Troubleshooting 3 This chapter provides troubleshooting procedures for problems encountered during installation of the SR2122-2 Storage Router and consists of the following sections: ■ Solving Problems at the Component Level ■ Identifying Startup Problems ■ Troubleshooting the Power Supply ■ Troubleshooting a Network or Fibre Channel Port Connection ■ Contacting Customer Service IP Storage Router SR2122-2 User Guide 49
PAGE 50
Troubleshooting Solving Problems at the Component Level The key to troubleshooting the SR2122-2 is to isolate the problem on a specific storage router component. The first step is comparing what the storage router is doing to what it should be doing. Because a startup problem is usually attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the storage router.
PAGE 51
Troubleshooting Identifying Startup Problems Observe the operation of the SR2122-2 and its front-panel LEDs to determine startup problems. LEDs indicate storage router status in the startup sequence. By checking the LEDs, you can determine when and where the storage router failed in the startup sequence. To power up the storage router: 1. Listen for the chassis fan assembly operation. If it does not operate, see “Troubleshooting the Power Supply” on page 52.
PAGE 52
Troubleshooting Troubleshooting the Power Supply To help isolate a power problem: 1. Check the POWER LED. ■ If the POWER LED is off, verify that the power switch is in the on position. ■ If the power switch is on, unplug the power cord and then plug the power cord back in. ■ If the POWER LED remains off, continue with the next step. 2. Connect the power cord to another power source if one is available. ■ If the POWER LED comes on, the problem is the first power source.
PAGE 53
Troubleshooting Troubleshooting a Network or Fibre Channel Port Connection If an LED on a network or Fibre Channel port indicates a problem, follow the steps in the next sections to isolate the problem: ■ Troubleshooting a Connection to a Gigabit Ethernet Port ■ Troubleshooting a Connection to a 10/100 Ethernet Management or 10/100 Ethernet HA Port ■ Troubleshooting a Connection to a Fibre Channel Port Troubleshooting a Connection to a Gigabit Ethernet Port A bad connection to a Gigabit Ethernet (GE
PAGE 54
Troubleshooting Troubleshooting a Connection to a 10/100 Ethernet Management or 10/100 Ethernet HA Port A bad connection to the 10/100 Ethernet Management or the 10/100 Ethernet HA port (MGMT 10/100 or HA 10/100) is indicated by the ACT LED being off. If the ACT LED is off: 1. Verify that the cable is connected properly and is in good operating condition. ■ Verify that the cable is the correct type of cable. (See Appendix B, “Cable and Port Pinouts.”) ■ Disconnect and connect both ends of the cable.
PAGE 55
Troubleshooting Troubleshooting a Connection to a Fibre Channel Port A bad connection to a Fibre Channel port (FC 1 and FC 2) is indicated by the LOG LED flashing twice per second. If the LOG LED is flashing twice per second: 1. Make sure that the Domain ID of the Storage Router is configured properly. If the Domain ID is configured properly, continue to the next step.

PAGE 60
Software Overview 60 ■ Secure Sockets Layer Support provides HTTPS connection for secure access through the web-based GUI. ■ Secure Shell (SSH) protocol version 2 support provides high encryption and authentication for interactive management sessions, and is a common replacement for Telnet. ■ Routing Information Protocol (RIP) listening support allows the SR2122-2 to learn dynamic routing using RIP (version 1 or version 2) listening.
PAGE 61
Software Overview SCSI Routing Overview SCSI routing provides IP hosts with access to FC storage devices as if the storage devices were directly attached to the hosts, with access to devices being managed primarily in the storage router. An iSCSI target (also called logical target) is an arbitrary name for a group of physical storage devices. The iSCSI targets are created and mapped to physical storage devices attached to the storage router.
PAGE 62
Software Overview Routing SCSI Requests and Responses SCSI routing consists of routing SCSI requests and responses between hosts in an IP network and FC storage. FC storage IP hosts HP SR2122-2 IP SCSI requests and responses 15022 Figure 32: Routing SCSI requests and responses for SCSI routing Each host that requires IP access to storage via an IP Storage Router 2122-2 needs to have a compatible iSCSI driver installed.

Software Overview Access for SCSI routing is controlled in the IP hosts and the storage router. In an IP host, the Gigabit Ethernet IP address of the SCSI routing instance in the storage router with which the host is to transport SCSI requests and responses is configured in the iSCSI driver. In a storage router, access is controlled through an access list and a VLAN identifier (VID) number of the hosts. Additionally, access can be further controlled in the storage router through authentication.
PAGE 67
Software Overview Note: The purpose of Figure 35 and Table 7 is to illustrate the concept of storage mapping and access control. The IP addresses will vary according to each site. Similarly, the type of storage addressing (for example, LUNWWN, WWPN + LUN or LUN serial number) will vary according to the types of storage and the types of storage addressing preferred at each site.

Software Overview FCIP Overview Fibre Channel over IP (FCIP) enables SR2122-2 Storage Routers to provide connectivity between FC hosts and FC storage devices over an IP network. To deploy FCIP, two SR2122-2 Storage Routers are required. Each system is configured for FCIP and connected to a SAN (or to any FC host or FC device). The peer systems are connected to each other through an IP network.
PAGE 70
Software Overview The peer systems deployed for FCIP must be configured to use the TCP protocol. TCP protocol uses standard TCP flow control and error recovery algorithms and should be used if you require a standards-based FCIP implementation or connect to a non-SR2122-2 peer. With the TCP protocol one FCIP instance must be configured as the TCP client; the other FCIP instance must be configured as the TCP server.
PAGE 71
Software Overview FCIP Network Structures This section describes typical FCIP network structures. In all of these examples a management station (not shown) manages the storage routers through an IP network connected to the management interface and/or HA interface of each storage router. Figure 36 represents a basic, non-redundant structure of an FCIP network configuration.

Software Overview Mixed Mode Overview When the SR2122-2 is deployed for SCSI routing you can optionally configure one of the internal FC initiator interfaces for FCIP. When it is deployed for FCIP, one of the internal FC initiator interfaces can be configured for SCSI routing. This mixed mode deployment allows the storage router to provide IP hosts with access to the FC storage via one initiator interface and FCIP connectivity for FC hosts and FC storage devices via the other initiator interface.
PAGE 75
Software Overview Basic Network Structure When a storage router is deployed for SCSI routing and FCIP, IP hosts with iSCSI drivers access the storage router through the IP network connected to the storage router’s Gigabit Ethernet interfaces. The storage router accesses the storage devices or intelligent storage array connected to the Fibre Channel interfaces. Access to the FC interfaces is made through the internal FC initiator interface configured for iSCSI traffic.

Software Overview Cluster Management Overview You can configure storage routers in a cluster to allow the storage routers to back each other up in case of failure. Note: A storage router can participate in a cluster only if it is deployed for SCSI routing.
PAGE 80
Software Overview Interface Naming Configuring the SR2122-2 Storage Router software requires that you understand hardware interface naming. This section describes the interface naming system used with the storage router hardware. Each storage router interface is assigned a three-character name consisting of two lower case letters followed by a number. The letters designate the interface type; the number designates the chassis slot occupied by the interface.

PAGE 102
Configuring System Parameters Configuring IP Routes If the storage router requires access to any IP address outside the management subnet, you must configure the appropriate routes in the SR2122-2 routing table. You can configure static routes, or if you are using RIP in your network, you can enable the storage router to dynamically learn routes using the routing information protocol (RIP).
PAGE 103
Configuring System Parameters The SR2122-2 RIP implementation runs RIP v2 in broadcast mode. This allows the storage router to learn from either RIP v1 or RIP v2 hosts that are operating in broadcast mode. The storage router will not learn routes from RIP v2 hosts operating in multicast mode. Note: The storage router is a passive, or silent, RIP device; it updates routes based on RIP advertisements but it does not advertise. 1. enable — Enter Administrator mode 2. ip rip enable — Enable RIP listening.

Configuring Authentication 10 This chapter explains how to configure the authentication portion of HP authentication, authorization, and accounting (AAA) methods on the storage router, and how to enable iSCSI authentication, which uses the AAA authentication methods.
PAGE 146
Configuring Authentication Prerequisite Tasks Before performing AAA and iSCSI authentication configuration tasks on the storage router, make sure you have configured system parameters as described in Chapter 5, “Configuring the Storage Router” and Chapter 6, “Configuring System Parameters” If the storage router is deployed for SCSI routing, you should also configure SCSI routing instances as described in Chapter 8, “Configuring SCSI Routing” before proceeding.
PAGE 147
Configuring Authentication This chapter describes how to configure the following AAA security services: ■ RADIUS is a distributed client/server system implemented through AAA that secures networks against unauthorized access. In this implementation, the storage router sends authentication requests to a central RADIUS server that contains all user authentication and network service access information.
PAGE 148
Configuring Authentication Remote RADIUS servers Remote TACACS+ servers Username database user password user password user password user password user password user password ... ..... ... ..... When authentication is enabled, the SCSI routing instance passes the user name and password from the iSCSI driver to AAA for authentication. AAA uses the authentication list to determine which services to use for the authentication attempt.
PAGE 149
Configuring Authentication Remote RADIUS servers IP 10.5.0.53 IP 10.6.0.61 Key: rad123SN Remote TACACS+ server IP 10.7.0.
PAGE 150
Configuring Authentication Configuring Security Services Configuring security services consists of setting the appropriate parameters for the various service options that can be used by the storage router. The SR2122-2 can use any or all of the supported security services. Use the procedures that follow to configure the storage router to use the appropriate security services: ■ RADIUS Servers ■ TACACS+ Hosts ■ Local Username Database RADIUS Servers To configure RADIUS security services: 1.
PAGE 151
Configuring Authentication TACACS+ Hosts To configure TACACS+ security services: 1. enable — Enter Administrator mode. 2. tacacs-server host 10.7.0.22 — Specify the TACACS+ server to be used for AAA authentication services. For example, specify the TACACS+ server at 10.7.0.22 for use by the Storage Router. Because no port is specified, the authentication requests use the default port 49. The global timeout value is also used. 3.
PAGE 152
Configuring Authentication ■ Passwords are entered in clear text. However, they are stored in an encrypted format. ■ If the password contains embedded spaces, enclose it with single or double quotes. ■ After initial entry, passwords display in their encrypted format. Use the show aaa command to display the local username database entries.
PAGE 153
Configuring Authentication Building the AAA Authentication List iSCSI authentication uses a list of defined AAA authentication services to administer its security functions. The list that is created must be named default. To build a list of AAA authentication services to be used for iSCSI authentication: 1. enable — Enter Administrator mode. 2. aaa authentication iscsi default local group radius group tacacs+ — Create a list (named default) of authentication services.
PAGE 154
Configuring Authentication Testing iSCSI Authentication Before enabling iSCSI authentication for a SCSI routing instance, you can test iSCSI authentication from the storage router. The user name and password are passed to AAA authentication, which performs authentication using the iSCSI default authentication list. The command response indicates a pass or fail status. To test iSCSI authentication: 1. enable — Enter Administrator mode. 2.
PAGE 155
Configuring Authentication Verifying and Saving Configuration You can save the configuration at any time using either the save aaa bootconfig or save all bootconfig commands. You must save the authentication configuration for it to be retained in the storage router when it is rebooted. To verify and save authentication settings: 1. enable — Enter Administrator mode. 2. show aaa — Display AAA authentication configuration (Example 13). 3.

Configuring a High Availability Cluster 11 This chapter explains how to configure SR2122-2 Storage Routers in a cluster to allow the storage routers to back each other up in case of failure. The following tasks are covered: ■ Prerequisite Tasks ■ Adding the Storage Router to a Cluster ■ Changing Clusters High availability clusters can be configured using CLI commands, as described in this chapter, or via the web-based GUI.
PAGE 158
Configuring a High Availability Cluster Prerequisite Tasks Before performing any high availability cluster configuration tasks, make sure you have configured system parameters, including the HA interface, as described in Chapter 5, “Configuring the Storage Router” and Chapter 6, “Configuring System Parameters” When you configure SCSI routing instances to run in a high availability cluster, follow these guidelines: ■ If you map targets using WWPN, be sure to specify both the primary WWPN (the WWPN associat
PAGE 159
Configuring a High Availability Cluster The following storage router configuration settings are shared cluster-wide, and when configured on the first storage router in the cluster, will be shared with the other storage router that joins the cluster.
PAGE 160
Configuring a High Availability Cluster 3. To verify that both storage routers in the cluster include the same configuration, issue the following commands from the principal storage router in the cluster: ■ show accesslist all from bootconfig ■ show scsirouter all from bootconfig ■ show vlan ■ show vtp Issue the same commands from the storage router just added to the cluster. The displays should be the same. 4.
PAGE 161
Configuring a High Availability Cluster 2. When the storage router restarts, it communicates with other member of the cluster to obtain current cluster configuration information. Once the storage router is completely restarted, verify the new cluster configuration. Issue the show cluster command to verify the cluster name and confirm that the storage router is exchanging heartbeats with the other member of the cluster. 3.
PAGE 162
Configuring a High Availability Cluster Adding Completely Configured Storage Routers You may prefer to completely configure both storage routers (including SCSI routing instances and access lists) as standalone systems before joining them into a cluster. The following example explains the steps required to create a cluster named Cluster1, composed of two storage routers named StorageRouterSys1 and StorageRouterSys2.
PAGE 163
Configuring a High Availability Cluster 5. Add SvSys2 to the new cluster named Cluster1, using the Setup Cluster Configuration Wizard. When prompted, enter retain to share the existing SCSI routing instances across the cluster. 6. Use the show cluster command to verify the cluster name after StorageRouterSys2 reboots. Verify that the defined SCSI routing instances were retained, using show scsirouter command. 7. Restore any access lists saved in Step 3 using the restore accesslist from command.
PAGE 164
Configuring a High Availability Cluster 3. If you are going to retain data, determine if you have any duplicate SCSI routing instance names. When the storage router is added to the cluster, the data in the cluster will overwrite the existing data. You may prefer to change the configuration in the storage router before it joins the cluster to prevent this situation. 4. If you are going to retain data, determine if you need to save existing access list information. Access lists are not retained.
PAGE 165
Maintaining and Managing the Storage Router 12 This chapter explains how to perform normal maintenance and management tasks associated with the storage router.
PAGE 166
Maintaining and Managing the Storage Router Prerequisite Tasks Before performing any storage router maintenance tasks, make sure you have configured system parameters as described in Chapter 5, “Configuring the Storage Router” and Chapter 6, “Configuring System Parameters”. Note: Certain configuration tasks, such as identifying a location from which to download software, are optional and may not have been performed during initial configuration.
PAGE 167
Maintaining and Managing the Storage Router command, the machine must be accessible using the Trivial File Transport Protocol. If the machine is not running a web server or accessible via TFTP, use the storage router web-based GUI to make the updated software available to the storage router. (See the online Help for details.) The download location used for retrieving updated storage router software is set using the software http url, software proxy url, or the software tftp commands.
PAGE 168
Maintaining and Managing the Storage Router Proxy Url: http://www.hp.com Proxy Username: SWAdmin01 Proxy Password: ********* Tftp Hostname: 10.1.1.122 Tftp Directory: SR2122/v2.3/ Disk Space Available: 13357.0 KB Current Version: 2.3.1 Boot Version: 2.3.1 To update storage router software: 1. Identify the location from which to retrieve the updated storage router software. (This is either http://www.hp.com/support or another download location of your choosing, as previously described.) (Optional) 2.
PAGE 169
Maintaining and Managing the Storage Router Using HTTP To specify the HTTP download location: 1. enable — Enter Administrator mode. 2. show software version all — List the software versions currently available for booting, along with the current download locations. Verify that the version of software required is not already available. Verify that the current download location information for HTTP is correct. 3. software http url http://10.1.11.
PAGE 170
Maintaining and Managing the Storage Router 4. software proxy address http://10.1.10.126 port 32 — This is the address and port number of the proxy server that will be used to access the URL specified in Step 3 (for example, http://10.1.10.126, port 32). (Optional) 5. software proxy username HPuser password HPpswd — Use this command to define the user name and password needed to access the selected download location. For example, specify user name HPuser and password HPpswd.
PAGE 171
Maintaining and Managing the Storage Router To make a new version of software available to the storage router: ■ Using HTTP ■ Using Proxy Services ■ Using TFTP Using HTTP To make a new version of software available to the storage router via HTTP: 1. enable — Enter Administrator mode. 2. show software version all — Verify that there is only one version of software on the storage router.
PAGE 172
Maintaining and Managing the Storage Router Note: There may be times when you need to make special software available to the storage router, for example, under the guidance of a HP Technical Support professional. If you isolate this software from standard updates by placing it in another location (not the default download location), you could change the default download location, download the software, and then reset the default download location.
PAGE 173
Maintaining and Managing the Storage Router Setting Updated Software as Boot Version Downloading updated software to the storage router does not change the currently running version of the software, nor does it automatically set the new version to be booted at next system restart. You must take specific action to make the new software version bootable.
PAGE 174
Maintaining and Managing the Storage Router Backing Up System Configuration Backing up the system configuration consists of saving selected storage router configuration information to XML files that can be stored both locally and remotely. Should problems occur, AAA authentication information, SCSI routing instances, access lists, VLANs, and other storage router system configuration information can be restored from these files.
PAGE 175
Maintaining and Managing the Storage Router Storing Backups to a Remote TFTP Server To create a backup configuration file named backup1 and to copy that backup file to another file named back1.xml, located on the TFTP host, tftpserver1, in the default directory, /tftpboot: 1. enable — Enter Administrator mode. 2. save all backup1 — Save the current running configuration to a file called backup1 in the savedconfig directory. 3. copy savedconfig: backup1 tftp://tserver1/ back1.
PAGE 176
Maintaining and Managing the Storage Router Restoring a Deleted SCSI Routing Instance For example, suppose the SCSI routing instance, scsi1, was inadvertently deleted. To restore scsi1 from a configuration file that was saved to a URL: 1. enable — Enter Administrator mode. 2. copy http://10.1.1.44/~s1/back1.xml savedconfig: scsi1_restore.xml — Copy the specified configuration file from the designated URL and place it in the savedconfig directory, using the file name, scsi1_restore.xml. 3.
PAGE 177
Maintaining and Managing the Storage Router Restoring an Existing SCSI Routing Instance If you need to restore the configuration of a SCSI routing instance that is still active in the storage router, you must stop the instance, restore the configuration from the selected file, then restart the instance. For example, to restore the SCSI routing instance, scsi2, from the file, scsi2_backup. 1. enable — Enter Administrator mode. 2.
PAGE 178
Maintaining and Managing the Storage Router Restoring an Access List When you restore an access list, existing entries are never deleted. The restore will add missing entries and overwrite entries of the same name, but will never purge or delete existing entries. If necessary, you can delete an entire access list and then restore if from a saved configuration file. Use the following procedure to restore the access list, mylist1, from the file, accesslist_backup.xml.
PAGE 179
Maintaining and Managing the Storage Router 4. restore accesslist mylist1 from accesslist backup.xml — Restore the access list entries for mylist1 from the saved configuration file, accesslist_backup.xml. 5. show accesslist mylist1 — Display the entries for the restored access list, mylist1. The entries are: ■ 10.1.1.30/32 ■ 172.16.255.220/32 ■ 209.165.200.225/32 ■ chap-username 12h7b.lab2.webservices ■ chap-username 12784.lab1.webservices ■ chap-username test2.sys3 6.

Use the following procedure to properly power down a storage router.
PAGE 184
Maintaining and Managing the Storage Router Note: If the storage router is operating in a cluster environment, any SCSI routing instances running on this storage router fail over to another storage router in the cluster. If you are operating in a cluster environment but do not want SCSI routing instances to fail over, issue the no scsirouter enable command for all instances (or selected instances that should not fail over) before you issue the clear conf command.

PAGE 186
Maintaining and Managing the Storage Router 2. save all myfile — Save all configuration information in a file called myfile. This file is stored in the savedconfig directory. 3. clear conf — Clear the current configuration but retain system information (such as management and HA interfaces, logging table, DNS, Administrator and Monitor passwords, NTP server, and SNMP information) and saved configuration files. At the prompt, enter the Administrator password.
PAGE 187
Maintaining and Managing the Storage Router Recovering Passwords The storage router management interface is password protected. You must enter passwords when accessing the storage router via Telnet (for the CLI) or the web-based GUI. Password protection can also be enabled for the storage router console interface, requiring that the same Administrator and Monitor mode passwords that are configured for the management interface be applied to the console interface.
PAGE 188
Maintaining and Managing the Storage Router Making Changes to Instance Configurations Note: To assure that changes are correctly propagated to all storage routers within a cluster, always modify the configuration of a SCSI routing instance from the storage router where the instance is currently active. Frequently you will make changes to the SCSI routing instance configurations. Changes include such actions as adding or deleting a target, adding or deleting a LUN, remapping a target, or modifying access.
PAGE 189
Maintaining and Managing the Storage Router Enabling and Disabling Connections A SCSI routing instance becomes active, by default, once it is associated with a Gigabit Ethernet interface to IP hosts. Each target that is added to an instance is also, by default, enabled. However, no IP hosts can connect or log in to that target because the target has no access list association.

PAGE 191
Maintaining and Managing the Storage Router Once a SCSI routing instance has been stopped, it can be re-activated by issuing the scsirouter enable command. The scsirouter enable command must be issued from the same storage router as the no scsirouter enable command. See the IP Storage Router 2122-2 Command Line Interface User Guide for command details.
PAGE 192
Maintaining and Managing the Storage Router Note: If some targets are available but others are not, failover of the SCSI routing instance does not occur. Each cluster supports up to 12 active SCSI routing instances. Since each storage router can also support up to 12 SCSI routing instances, high availability is ensured for each instance in the cluster (regardless of the division of those instances between storage routers).
PAGE 193
Maintaining and Managing the Storage Router Note: Because there are only two storage routers in the cluster, you do not need to specify the failover destination. 4. show cluster or show scsirouter scsi1 stats — Verify that the specified SCSI routing instance, scsi1, is no longer running on the storage router, StorageRouterSys1.
PAGE 194
Maintaining and Managing the Storage Router 4. save scsirouter scsi2 bootconfig — Save the current SCSI routing instance configuration, including the primary setting, and circulate the changed configuration around the cluster. 5. failover scsirouter scsi2 — Failover the desired SCSI routing instance, scsi2.
PAGE 195
Maintaining and Managing the Storage Router Managing CDP on the storage router Cisco Discovery Protocol (CDP) is primarily used to obtain protocol addresses of neighboring devices and to discover the platform of those devices. CDP is mediaand protocol-independent and runs on all Cisco-manufactured equipment including routers, bridges, access servers, and switches. Each device configured for CDP sends periodic messages, known as advertisements, to a multicast address.
PAGE 196
Maintaining and Managing the Storage Router Modify the CDP Holdtime and Timeout Values Holdtime is the amount of time the receiving device should hold a CDP packet from the storage router before discarding it. The CDP holdtime value must be set to a higher number of seconds than the CDP timer value (the time between CDP transmissions from the storage router). For example, the default CDP holdtime value is 180 seconds. The default CDP timer value is 60 seconds.
PAGE 197
Maintaining and Managing the Storage Router ■ You can extend commands across line boundaries by ending a line with a backslash ( \ ) as the continuation character (Example 23). Use the continuation character to make long commands more readable. The line sequence is continued until a command line without a continuation character is encountered. If a comment line is used to end a line continuation sequence, you must add a blank line after the comment. Example 23: Extended Commands: radius-server host 10.5.

Maintaining and Managing the Storage Router Use the force keyword to execute the script immediately without asking for confirmation. (Optional) After the script completes, issue the appropriate show commands to verify that the script executed as expected. Managing the Log File The storage router can log event information to a series of log files, based on the routing rules specified in the storage router logging table.
PAGE 199
Maintaining and Managing the Storage Router Clearing the Log Files To periodically clear the storage router log files. 1. enable — Enter Administrator mode. 2. show logging size — Check the current size of the storage router log files (Example 24). 3. show logging all or show logging last 50 — Display all the current log file entries (first command), or display a selected number of entries, such as 50, from the end of the file (second command). 4. clear log — Clear the existing log file.
PAGE 200
Maintaining and Managing the Storage Router Using the Crash Log If the storage router experiences an unexpected problem that forces it to automatically reboot, a special log file is generated. The file is named crash.txt and is stored in the log directory (/ata4/log). You can display the contents of this file to the console using the show crash command. To save the show crash command output, redirect the output of your console using the logging facilities for your specific console interface.

Maintaining and Managing the Storage Router Capturing System Messages at Bootup The storage router logs a variety of messages to the console during the system boot process. If you are experiencing problems with the storage router, it may be helpful to capture these messages. Use the console interface to perform the boot process and capture the console log using typical external methods. Understanding Logging The storage router generates a variety of system event messages.

PAGE 207
Maintaining and Managing the Storage Router Filtering and Routing Event Messages The storage router logging table allows messages to be filtered by their facility and notification level and routed to the specified destination(s). When an event message arrives, the logging table rules are searched by facility name and by level until the first match is found. The message is sent to all the destinations specified by the matching rule. If no match is found, the event message is discarded.
PAGE 208
Maintaining and Managing the Storage Router Use the no logging on command to quickly disable logging for all destinations without modifying the storage router logging table. No logging will take place until logging is re-enabled by the logging on command. If you clear the logging table without returning to the factory defaults, all rules are removed from the logging table. This causes all messages to be discarded because there are no matching rules in the logging table.

Recommended Host/Storage Configurations FCIP with Local iSCSI Hosts One or more host servers may be connected to the extended SAN through a local IP network at site A using the iSCSI protocol. This connection is shown in Figure 56 using the second Gigabit Ethernet port on the site A SR2122-2.
PAGE 230
Recommended Host/Storage Configurations FCIP with Remote iSCSI Hosts The FCIP configuration with local iSCSI hosts may be extended by locating the iSCSI hosts apart from either site A or site B. This configuration requires that the iSCSI IP network be connect to the large SAN through a WAN network as shown in Figure 57.
PAGE 231
Recommended Host/Storage Configurations network bandwidth, the iSCSI protocol traffic can theoretically consume some or all of the bandwidth allotted to the FCIP connection. If that happens, both iSCSI and FCIP I/O commands are subject to failure due to dropped packets in the WAN network. By isolating the iSCSI protocol from the FCIP protocol using separate network connections, it is possible to prevent a failure in the FCIP portion of the system due to over-subscription of the WAN connection.
