Description This chapter describes AMC (the ADIC Management Console). AMC is a fully-featured management tool for storage-area networks (SANs) with storage networking controller (SNC) or management control blade (MCB) connectivity. A SAN is a network linking servers or workstations to disk arrays, tape backup systems, switches, bridges, and other devices, over high-speed transports such as Fibre Channel or gigabit Ethernet.
AMC provides several levels of access permissions and the ability to customize views and portals. By keeping track of different client views, you can recall a saved view from any client. The server provides security features by maintaining account names and passwords on behalf of the client application. AMC also provides functionality to support server-less backup, tools for LUN mapping, and easy channel zoning. ADIC Management Console Functionality AMC uses a three-tier client/server model.
Heartbeat AMC monitors system components to ensure continuity of service. If an SNC or MCB is no longer available, the server component notifies monitoring clients.For more information, refer to Checking the Heartbeat on page 103. Health Checks Instantaneous and periodic health checks allow monitoring of each appliance and the devices attached to it. For more information, refer to Using Health Check on page 102.
SNMP SNMP (Simple Network Management Protocol) community strings are a part of the software agent’s messaging functionality that serve to group network devices into logical collections for management purposes. The community strings on the server must match those on the appliance(s) you wish to manage.
ADIC Management Console User’s Guide 7
8 Description
Getting Started The AMC server communicates over Ethernet to its clients. To manage a SAN, install an instance of the server onto any open-platform system that is connected via Ethernet to each SNC and each AMC client. You must install at least one instance of the server to manage your SAN with AMC. The AMC client can be launched from any connected system on which it is installed. For intelligent-platform libraries, a library management client can also be launched from the AMC SAN client.
HP-UX The installation requirements for HP-UX are as follows. • HP-UXTM 11.0 or later • 80MB or greater system memory • 60MB free disk space in the destination partition Solaris The installation requirements for Solaris are as follows. • SolarisTM 2.7 or 2.8. The maintenance level must support JDK 1.4.
CAUTION 1 Verify that you have enough space, about 100 MB, in the temporary directory to be able to complete the installation. Obtain the network parameters for the client, the server, as well as any other Scalar libraries in the SAN. • Use static IP addresses. • If the Scalar libraries in the SAN are not on the same TCP/IP subnet as the server, assign a default network gateway address and/or route table entries. 2 Save this configuration information for future reference.
Installing the Server on a UNIX System Install the AMC server after you have completed the steps in Before Installing AMC on page 10. 1 Load the product CD. 2 Navigate to the ADIC Management Console folder. 3 Open the folder and copy the image file to a temporary folder on the host. CAUTION Verify that you have enough space, about 100 MB, in the temporary directory to be able to complete the installation.
9 • Network name of your mail server, for example, MyMailServer. • Valid email account for the specified SMTP server, for example, Joan.Dow • Valid password for this email account, for example, *u!nBe • Email address that you want mail recipients to see when AMC contacts them. This need not be an email address that has been previously validated by a working mail server, for example, AMCAlert@MyCompany.com Proceed to Launching the AMC Server on page 13.
Note Do not close the server window. Follow the exit procedure in Shutting Down the AMC Server on page 19 to shut the server down. Proceed to Launching the AMC Client on page 15. Installing the AMC Client The AMC Client is used to manage your SAN.
CAUTION Verify that you have enough space, about 80 MB, in the temporary directory to be able to complete the installation. On Solaris systems, if the /tmp directory is not big enough for InstallAnywhere to operate, the installation fails, even if the temporary directory is resized later. Set the IATEMPDIR environment variable to have the name of a directory which is big enough. Then InstallAnywhere will use that directory instead of /tmp.
2 Select Client to launch the program. When the client launches, both the ADIC Management Console window and a Receive Event Traps window appear. If event traps are issued, messages appear in the Received Event Traps window. You cannot close the Received Event Traps while the client is running but you can minimize it. 3 If the remote server is running on a system that is also remote to the client, the client window displays a prompt for you to connect to a server.
Logging on The Log On dialog box is displayed automatically when a new connection to the server has been established. It can also be displayed when you select Session and then select Log On. The Logon dialog box is also displayed when you select the Log On toolbar button. In the Logon dialog box, type "admin" as the user name. Type "password" as password, if this is the first time you have logged on. CAUTION After the initial log in, set up another SAN administrator.
The default master portal consists of all the devices discovered, according to the discovery configuration file. When the download is complete, the AMC screen is filled with data. For information about this screen, refer to Reading the SAN Management Information Panels on page 26. Logging off Log off after you finish using AMC. You will not need to restart the client before your next management session. 1 Select the Session menu, then select Log Off. A warning dialog box is displayed.
Select No if you have changed your mind. If you select No, you are returned to your view. 3 Select Yes if you have made changes to the view that you want to save. Select No if you do not want to save changes. Exiting the AMC Client Exit stops the AMC client application and closes its window. Use Exit if you want to restart the client application the next time you use AMC. Normally you will only log off, and leave the client running between sessions. 1 After logging off, select Session > Exit.

The SAN Management Interface The AMC interface presents you with a number of menus and toolbar buttons. Menus AMC organizes user commands into a number of different menus: • The Session menu consists of commands governing your current established connection: connecting to the server, logging off and on, changing your password, and exiting the program.
Panels The AMC interface consists of three information panels: • The navigation panel presents you with a hierarchically organized representation of SAN components, using special graphical conventions as well as textual information to represent SAN structure • The graphical panel presents you with a nontextual representation of your SAN, except for the textbearing menus mapped to hotspots • The data panel lists component, configuration, and build specifications for SAN components Received Event Trap W
• Scalar 1000 tape libraries contain three SNCs • Scalar 100 tape libraries contain one SNC • Scalar 24 tape libraries contain one SNC SNC nodes expand to show channels. Channels expand to show attached hosts and devices. The node symbol for SNCs and channels also functions as a toggle. Clicking it a second time collapses the expansion. Refer to Figure 1.
Figure 1 on page 27 shows a navigation panel with several navigation elements expanded. Because the SNC 5100 with IP address 172.16.76.215 is selected, it is shown in the navigation panel with blue highlighting. This SNC is aggregated into a Scalar 1000. For a list of symbols used in the graphical and navigation panels, see Figure 2. Figure 2 Symbols used in graphical and navigation panels For a summary of channel mode graphics, see Figure 3.
Target is the default mode for Fibre Channels. They are shown in blue. When channels are set to Target, you are able to see attached hosts. You must first be running the host registration software (HRS). Talk to your service representative about installing this software. Green indicates that the channel is in Initiator mode. Initiator is the default mode for SCSI channels.When channels are set to Initiator you are able to see attached devices.
Figure 4 AMC representation of the Scalar i2000 Scalar i2000 The navigation panel string representing the Scalar i2000 physical library consists of three elements: the IP address, the library’s name (for example, adiclib), and the library product identity (for example, Scalar i2000). Click the node symbol to the left of the library to show associated devices (drives) and partitions. All nodes have been expanded in Figure 4. The node symbol is a toggle. Clicking it a second time collapses the expansion.
The Scalar i2000 library In Figure 4 consists of a physical library divided into two partitions. In the line below the physical library line, the string representing the partition consists of two elements: the word Partition followed by the name of the partition. The partitions in Figure 4 are named SDLT and LTO. The tape device strings consists of the phrase SCSI Tape Device, followed by the location coordinates for the drive. Fibre Channel Tape Device is also possible in this area.
Pathlight VX The navigation panel string representing the Pathlight VX is analogous to the string for the Scalar i2000. Figure 5 shows the Pathlight VX as an expanded node. It consists of one virtual library named nyvp1_lib1. This virtual library consists of three drives. For more information about virtual libraries and drives, refer to the Pathlight VX online help.

Managing User Accounts AMC will enable you to create user accounts with the correct privilege levels for each user. Changing the Administrator Password SAN administrators must use this procedure to modify the SAN administrator password. To change a user’s password, refer to Modifying a User Account on page 42. Be certain to change the SAN administrator password periodically. CAUTION The default admin/password account is disabled after a new SAN Administrator account is created.
• Power user • Basic user The basic user has the most limited set of user capabilities, including access and view only of assigned portals. Power users have the basic user capability, as well as the ability to categorize assigned portals, save various views, and use all AMC tools—except Virtual Private Map (VPM)—to configure access. However, they cannot create, modify, or delete users, portals, or policies.
Table 2 User Capabilities Based on Privilege Level (Continued) Restart the appliance Y Y5 Y5 N Obtain CFL data Y Y Y5 N Obtain drive dumps Y Y Y5 N 1SA=SAN administrator 2PA=portal administrator 3PU=power user 4BU=basic user 5If the portal defined for the PA or PU includes only part of the appliance to be acted on, this privilege is assigned only to the SAN administrator.
Modifying a User Account SAN administrators and portal administrators use this procedure to modify another user’s privileges. If you are changing your own password, go to Changing the Administrator Password on page 39. 1 Log on as SAN administrator or portal administrator. 2 Select the Admin menu, point to User, then select Modify. 3 Select the name of the user whose privileges you want to modify in the Modify User Account grid. 4 Select Next.
Working with Portals This section contains procedures for administering portals. Portals are physical collections of libraries and SAN appliances that are available to users, as defined by the SAN Administrator. The SAN Administrator has access to the entire set of appliances and libraries described as the master portal. Creating a New Portal Create portals to assign access to devices, channels, views, and subportals.
New portals appear as subportals in the parent portal list. Modifying a Portal Note You cannot modify the master portal using this tool. 1 Log on as SAN administrator or portal administrator. 2 Select the Admin menu, point to Portal, then select Modify. 3 Select the portal that you want to modify. 4 Select Next. 5 Check or clear the boxes in front of SAN appliances to appropriately modify the portal definition. In the example, access to all the SCSI channels on 172.16.76.
Deleting a Portal A portal can be deleted without loss to stored data. Deleting the only portal for a user will result in that user having no access to the SAN. 1 Log on as SAN administrator or portal administrator. 2 Select the Admin menu, point to Portal, then select Delete. 3 Select the portal that you wish to delete. The Delete button becomes available. 4 Select Delete, and then select OK. The portal is deleted.
46 Working with Portals
Working with Categories and Views SAN components can be organized into logical groupings to facilitate SAN management. When you categorize your SAN, you choose the categories—subnet, department, location, host type, etc. AMC uses the file folder icon to represent a category. See Figure 2 on page 28 for more about icons used in the navigation panel. Working with SAN Categories Creating categories of SAN appliances is an easy way to help you manage your SAN.
4 Select Yes if you want to proceed. Otherwise, select No. The navigation panel refreshes to include lines for the categories. 5 Save the categories as a view. Refer to Saving Views on page 54. Creating a new Category Categories are used to group SAN components visually in the navigation panel and the graphical panel. 1 Log on as SAN administrator, portal administrator, or power user. 2 Select the view that is at the root of your display or the category you want to sub-categorize.
3 Right-click the category. Select Delete. 4 Or, having selected the category in the navigation panel, select the Category menu, then select Delete. The navigation panel window automatically refreshes. Moving a Category This section describes different ways to move categories. They are: • Use drag and drop • Use the Move Categories command 1 Log on as SAN administrator, portal administrator, or power user. 2 Select the category that you want to move.
In the example, the appliance at IP address 172.16.76.154 is selected. 3 Drag and drop it into the correct category. Be sure the cursor is pointing inside the folder icon of the target category. If you are moving the item to root, you can point anywhere on the root view line.
4 Continue until all items that you want to move have been moved. 5 Save the categories as a view. Refer to Saving Views on page 54. Moving Items by Using the Menu 1 Log on as SAN administrator, portal administrator, or power user. 2 Select the category into which you want to move items. 3 Select the Category menu, then select Move Items. 4 The Move Items dialog box is displayed. In the top of the dialog box, click, shift-click, or control-click to select all the appliances you want to move.
Opening Saved Views 1 Select the View menu, then select Open. The Open View procedure can also be initiated by selecting the Open View toolbar button. 2 If you already have an open view, you are prompted to confirm closing it. If you have unsaved changes in your current view, you are prompted to save it. Select Yes to save the current view. The view is saved. All SAN components disappear from the navigation panel display. The Open View dialog box is displayed.
Figure 8 New view at default master portal level Because the view was created directly under the master portal, Portal1 is displayed between the name and the portal affiliation. If the view had been created under the NewPortal or OtherNewPortal level (portals subordinated to the default portal), the numbered level would be Portal1.1, Portal1.2, etc. Figure 9 Numbered levels for views Portal 1 Portal 1.1 Portal 1.2 Portal 1.2.1 If you have not categorized your view, do so now.
Saving Views Creating views, which are logical organizations of SAN components, allows you to work more efficiently. You must save the views you create, or you will have to re-create them. If no changes have been made to a view, or the view is not newly created, the Save command is not available. 1 Log in as SAN administrator, portal administrator or power user. 2 Select the View menu, then select Save. The Save Current View procedure can also be initiated by the Save Current View toolbar button.
Type the search string into the dialog box. Select OK. The navigation panel refreshes to show the line containing the first occurrence of the search string highlighted in blue. 2 To continue the search, select Next Occurrence on the Find submenu of the View menu. The navigation panel refreshes to show the line containing the next occurrence of the search string highlighted in blue. If there is no next occurrence, a dialog box is displayed.

Performing Administrative Tasks This chapter describes procedures for a variety of administrative tasks.
Configuring Policies The policy engine is an expert system that allows AMC to alert persons specified by the administrator that certain SAN conditions have been met. These conditions are defined in terms of event traps. For more information about event reporting, refer to Monitoring and Managing Event Logs on page 93. 1 Select the Admin menu, point to Policy Configurations, then select New Policy. The Add New Rule dialog box is displayed. 2 Select Check traps when they arrive.
Discovering the SAN This section contains procedures for establishing and modifying the elements of the SAN. 1 Log on as SAN administrator. 2 Select the Admin menu, point to Discover SAN, then select Modify Discovery Configuration. The Discovery Configuration dialog box opens. All IP addresses are entered in dotted quad format, xxx.xxx.xxx.xxx. 3 Select a segment. 4 Do one of the following: To add a network segment for discovery, select Add. The Segment Configuration dialog box is displayed.
• SNMP Timeout values are entered in milliseconds. They limit the time allotted to wait for a response from each IP address that is being checked. The default value is intentionally set to a high number to make certain that all devices on a slow network are discovered. You may set the timeout value considerably lower than the default (5000 milliseconds) to speed discovery. • The SNMP Read Community on Scalar SNCs is set to public by default.
Two configurable strings are defined: • Read allows AMC to get information from appliances with matching Read community strings. • Write allows AMC to manipulate the settings of appliances with matching Write community strings. The appliance can maintain 32 Read and 32 Write community strings. CAUTION 1 Incorrect adjustment of the SNMP Community Strings can prevent the AMC from managing your system. Log on as SAN administrator.
Figure 11 Right-click from the navigation panel representation of appliance Refreshing Data Refreshing the appliance displays host, device, and connection status changes. Note After adding a device to a channel, rescan the channel and refresh data on the appliance. 1 Right-click an appliance in the navigation panel or the graphical panel. 2 Select Refresh Data. The displayed data will refresh. Note If you have turned off trap event notices, Refresh will not turn them back on.
After a few seconds the message Successfully received configuration from xxx.xxx.xxx.xxx appears in the Status/Message Area. 4 Select Save Locally. 5 A file browser opens. It defaults to the “cfg” subfolder of the “Client” folder. 6 Select Save. 7 Select Save on Server. After a few seconds the message Configuration file saved successfully appears in the Status/Message Area. Note 8 It is a good idea to save the configuration both locally and on the server to ensure that you have access to the file.
4 Select Load to continue with the load. Updating Firmware The Update Firmware command can only be used on appliances. To update firmware on a device attached to an appliance, go to Managing a Device on page 72. Note To update firmware on any component of an i-platform library, refer to the documentation for those systems. 1 Stop all I/O to the appliance. For instructions, refer to the Hardware User Guide for the appliance. 2 Log on as SAN administrator, portal administrator, or power user.
Select No to cancel the restart. Restarting...Please Wait appears in the Status/Message Area. Getting Information About a Library Scalar Library RMU data can be accessed by right-clicking the library and selecting the Show RMU Data command. For more information about displaying RMU data, refer to Displaying RMU Data on page 65. Note I-platform libraries do not have RMUs. Displaying RMU Data Not all appliances in the SAN are capable of providing this data.
66 Performing Administrative Tasks
Configuring Channels and Devices In the course of managing your SAN, you will want to rescan or reset channels, change connection modes and options, or update device or drive firmware. AMC has a structure in place to meet those needs. You can also adjust the device map from the AMC. Managing the SCSI Channel By right-clicking a network appliance’s SCSI channel, you can directly configure SCSI channel parameters, or instantly rescan and reset the SCSI channel.
Use Reset carefully because it causes pending I/O commands to return failed status back to the host operating system and may have unexpected results. Make sure all I/O is stopped before issuing this command. For instructions on doing so, refer to the appliance’s Hardware User Guide. CAUTION 1 Expand the appliance in the navigation panel or the graphical panel. 2 Right-click the appropriate SCSI channel graphic. 3 Select Reset. A warning is displayed. 4 Select Yes to continue.
Channel Mode Channel Mode identifies the channel as either an initiator or a target. When a SCSI channel is changed from target to initiator mode, the values that appear in the host ID and alternate host ID boxes do not default to 0. They default to values that the appliance has most recently used. Host ID Host ID is typically assigned as 7. Bus Reset on Power Up Bus Reset on Power Up is typically enabled. Removing the check mark from this box disables SCSI bus reset on power-up.
Resetting the Fibre Channel Using the Reset command cancels all pending commands, resets the channel, and performs a rescan. Use this command after making changes to the channel configuration. Use Reset carefully because it causes pending I/O commands to return failed status back to the host operating system and may have unexpected results. Make sure all I/O is stopped before issuing this command. For instructions on doing so, refer to the appliance’s Hardware User Guide.
Understanding Port Mode Options The Fibre Channel ports support Private and Public Fibre Channel attachments. The default port mode setting is Public Target. You can view the settings and change port parameters. INITIATOR In this mode, the port operates as an initiator allowing Fibre Channel targets (disks, tape devices, or FC switch) to attach to it. TARGET In this mode, the port operates as a target allowing a Fibre Channel initiator (host or FC switch) to attach to it.
Host Type Host Type has many possible values: AIX, AS400, Gateway, HP-UX, Linux, NT (includes Windows 2000, XP, and 2003), Netware, Generic, Solaris, and Autosense/NT (same as “NT”). Hosts running other operating systems use the setting Generic. The default setting is NT. The host type is either the name of the host operating system or the type of appliance attached to the port.
If I/O to the device cannot be stopped, or if you change your mind, select No to cancel the firmware upload. After the firmware upload is complete, you will be prompted to Restart the appliance. Refer to Using Restart on page 64. Editing Device Maps Some applications require LUNs to be presented in an order other than the order that the discovery routine presents them to the SNC. 1 Log on as SAN administrator, portal administrator, or power user.
Pre-Assigning Device Numbers The New Device command is used to assign a LUN to a device that is currently not present on the system, but for which a soft LUN—a LUN registered by the SNC during discovery—is not adequate. A medium-changer will typically be the first odd numbered LUN (1) if available, or the first odd LUN available after the last tape. Particular applications or tools may require settings that are different than the defaults.
Configuring SAN Access In addition to providing security via user privilege assignments, AMC allows you to configure SAN access for a particular channel or group of LUNs, or from a particular host perspective. Enabling Licensed Features Use the Feature Enable menu to enable licensed features for the selected appliance.
Data Mover Module Note Basic users are not authorized to enable the Data Mover Module. For user privileges, refer to Table 2 on page 40. The data mover module allows you to use server-free tape backup applications that support SNIA extended SCSI copy. Enabling this feature allows the appliance to move blocks of data directly between storage devices attached to it.
Installing HRS The Host Registration Service (HRS) presents host information that SNCs and MCBs use to manage host access and data retrieval. The information that is presented includes host name, host type, host connection and the online or offline status. This information is sent periodically over the host Fibre Channel connection. The default HRS setting re-registers the host every 5 minutes. You can change the re-registration period to any value between 1 and 255 minutes.
and press Enter. If a previous version of HRS is found, a message similar to the following displays: <219 ? 4 0:00 hrs> If no messages similar to the output in Step 3 display, proceed to Step 6. If a similar message displays, type pkgrm and press Enter. 5 If you removed a package, reboot the host: reboot -- -r 6 Load the product CD into the Solaris host. 7 Find the HstRegSrv.tar file. 8 Copy HstRegSrv.tar to a temporary directory. 9 From the directory that has HstRegSrv.
Installing the Host Registration Service for HP-UX Install this software on a host computer running the HP-UX operating system that is attached to an SNC, MCB or network chassis. 1 Verify that the HP-UX host you are configuring has an installed Host Bus Adapter (HBA). 2 Obtain HstRegSrv.depot from your service representative. 3 From the command line type sam and press Enter. 4 Select the Software Management menu, then select Install Software on the Local Host.
The software installs. 8 Reboot. 9 Optionally, change the re-registration period, by typing hrs -i[interval in minutes] -D & and press Enter. This causes HRS to run in the background as a daemon, registering at the specified time interval. The default re-registration period is 5 minutes. Installing the Host Registration Service for Linux To install HRS, perform the following steps: 1 Obtain the HRS file from the ADIC website or from your customer service representative.
Installing SFM Installation of SFM into a system with a developed SAN is different than installation of SFM into a new system. 1 Log in as SAN administrator, portal administrator or power user. Note Basic users are not authorized to configure SFM. If the portal administrator or power user have access to a portal with only partial access to the SFM configuration, only the SAN administrator can modify access.
Figure 12 Scalar Firewall Manager access settings dialog box Figure 12 shows labeled components of the Scalar® Firewall Manager Access Settings dialog box. Registered hosts are shown in the column on the left. When a host is online its name is displayed in black. When a host is registered but not currently online its name is displayed in blue. To have complete host information appear in the display, you must first be running HRS. Consult your service representative.
• To select or deselect access to all LUNs for a host, find the host’s name in the list of hosts in the upper left corner of the screen and select it. Then select Select All or Deselect All. Figure 13 on page 83 shows LUNs assigned so that no host can access LUNs that any other host is accessing. Figure 13 5 LUNs restricted for selective access by four hosts Select Apply to keep the changes you made to host data fields and LUN assignments.
• Select the correct Host Type, which is the operating system or appliance type, from the Host Type drop-down list. • The Host Connection consists of the port number that the host attaches to, the host’s IP Address, and information about the HBA. • You must know the host’s World Wide Name to add it manually. 3 When you are finished, select either Accept New Host or Quit New Host. 4 Select the Apply button to keep the changes you made to host data fields and LUN assignments.
Installing eVPS Installation of eVPS into a system with a developed SAN is different than installation of eVPS into a new system. Note 1 Basic users are not authorized to configure eVPS. If a portal administrator or power user has access to a portal with only partial access to the eVPS configuration, only the SAN administrator can modify access. Log on as the SAN administrator, portal administrator, or power user.
• From the appliance’s perspective • From the host’s perspective Assigning LUNs to host(s) using the appliance perspective 1 Make a list of which LUNs you want to assign to which host(s). A maximum of 64 hosts can be connected to a Fibre Channel. 2 Right-click the appliance with eVPS enabled. 3 Select the Access Options menu, select Extended Virtual Private SAN®. The eVPS Access Settings dialog box is displayed.

Troubleshooting the SAN This section references event codes and error messages that may appear in the event trap window or the event log maintained by the AMC server. For in-depth maintenance, repair, and troubleshooting information refer to the maintenance manual for your library or the hardware guide for your SNC. Monitoring and Managing Event Logs For libraries that have an SNC, submenus under Events allow you to control the way the event log is displayed and how traps are generated.
• If you do not want to print all the pages of a lengthy event log, click, shift-click and/or controlclick to select the lines you want to print. • Paste this text into a file editor. • Select the File menu, then select Print. Saving a Copy of Currently Displayed Entries 1 Right-click an appliance in the navigation panel or the graphical panel. 2 Select the Events menu, then select Save Event Log. 3 Type a name for the file in the browser dialog box.

Setting the Event Trap Threshold The Trap Threshold Level determines how many times an event can occur in a ten minute period before it is reported to client Received Event Trap windows. To receive email messages, in addition to event traps, refer to Configuring Policies on page 58. 1 Log on as SAN administrator. Note Portal administrators, power users, and basic users are not authorized to change event trap thresholds. For user privileges, refer to Table 2 on page 40.
1 Select the Received Event Traps window, which is always running when an instance of the client is running. It may be minimized, however. For more about the Received Event Traps window, refer to Reading the SAN Management Information Panels on page 26. 2 Look in the Received Event Traps window to see trap messages. Messages identify the appliance by its IP address. They also include a date and timestamp, an event code, and a description of the event that caused the trap.

Monitoring Environmental Data Not all appliances in the SAN are capable of providing this data. If the appliance you select is not capable of communicating this information, Get Environmental Data does not appear on the appliance menu.
4 When you are finished viewing the data, select OK. 5 Environmental data ranges may vary from appliance type to appliance type. Using Health Check Health Check allows you to determine periodically the operational state of SNC connections to the interfaces it controls. When the Health Check is disabled, the SNC performs no periodic checks beyond monitoring environmental status lines, which indicate power supply and temperature conditions.
4 • If you selected Cancel, above, and you want to adjust the interval when Health Checks are performed, repeat Step 1 - Step 3 above. • Then select the Interval tab. On the Interval tab, type the amount of time that should elapse between automatic health checks on the selected appliance. The interval can range from 0 to 65,535 minutes. The default interval is 60 minutes. Selecting 0 disables the Health check.
Checking the Command Flow Log Two kinds of events are recorded in the command flow log (CFL) file: sequence events and single command events. Sequence events are Read/Write commands. All other events are single command events. You can retrieve the CFL log file for use as a diagnostic tool. Not all appliances in the SAN are capable of providing CFL data. If the appliance you select is not capable of communicating this information, Command Flow Log does not appear on the appliance menu.
Figure 28 CFL output The output starts with the internal LUN number of the device for which information is being provided. The device’s vendor, product ID, and serial number are also listed in this line: LUN=1 Vendor=HP Product=Ultrium 1-SCSI SN=IE71K05450 After this line, numbered events pertaining to the cited LUN are printed. Each line begins with an event number.
106 Troubleshooting the SAN
Glossary This glossary consists of terms that can be used for components that you may have in your SAN. Aggregation The navigation panel representation of an SNC, so that it is subordinate to the Scalar library in which it is contained. AMC (ADIC Management Console) Client-server software. The AMC client-server is used to manage the SAN. Appliance An SNC, whether embedded or standalone. For example, the Scalar i2000 is not and does not contain an appliance, but the Scalar 100 contains an embedded appliance.
Event A condition that matches a numbered, predefined set of circumstances. The AMC client can be configured to display events at specified severity levels and to generate traps (also called “event traps”) for specified occurrences. Event log A list of all pre-defined events logged by the AMC server, whether or not the AMC client has been configured to display these events to the user. eVPS (extended Virtual Private SAN) A virtual LUN mapping scheme for Fibre Channel hosts that runs on the SNC.
LUN (Logical Unit Number) A unique identifier used on a SCSI bus to distinguish between devices that share the same bus. SCSI is a parallel interface that allows up to eight devices (target IDs) to be connected along a single cable. Each of these eight devices has access to 16 unique address spaces (LUNs). A specified intersection of target ID and target LUN can be construed as the Assigned LUN. LVD (Low Voltage Differential) A type of drive.
SFM (Scalar Firewall Manager) A virtual LUN mapping scheme for Fibre Channel hosts, allowing an overall LUN total of 2048 devices to be virtually remapped on a SAN-wide basis. SNC (Storage Networking Controller) ADIC term for a storage networking appliance. The SNC enables high-performance, networked communications that support intelligence functionality within the Scalar storage system. SNC menu An AMC menu that allows the user to configure the appliance parameters for an SNC.
