1 OVERVIEW Overview Key Features SAN Manager LM Architecture SAN Manager LM Components 13
Key Features Secure Storage Assignment SAN Manager LM provides SAN storage access control at the device or logical unit number (LUN) level. The storage security provided by SAN Manager LM enables users to build and manage complex SANs with heterogeneous servers and storage devices. IT managers can confidently assign storage to one or more hosts and be assured that no other hosts have access to the devices. SAN Manager LM allows the IT manager to view and manage an entire SAN from one centralized console.
available for immediate use. File systems on LUNs assigned to UNIX systems are also immediately available for use after the IT manager mounts the volumes. No Single Points of Failure Overview The SAN Manager LM software architecture has no single points of failure; therefore, introducing it into a system will not compromise availability. The SAN configuration database can be mirrored three ways to ensure that a copy will always be available.
Feature Benefit Share groups for cluster configurations Clear visualization of storage accessible to multiple hosts prevents errors when setting up cluster server and shared tape device environments. Fibre Channel topology independence Compatibility with Fibre Channel Arbitrated Loop and Switched Fabric topologies provides SAN configuration flexibility.

Creating the SAN Database About the Database The SAN Manager LM database stores important information such as administration groups, device assignments, and customized device information. To ensure reliability, the database design takes advantage of disk mirroring. By using a mirrored database, SAN Manager LM writes database information to multiple devices simultaneously, but reads from just one. If the active database device goes offline, another device from the mirror set takes over.
SAN Manager LM prompts you to create a database mirror set and database. 3. Click Yes. SAN Manager LM asks if you want to use the Database Wizard during the database creation procedure. Note 4. You cannot use the Database Wizard unless your monitor is capable of displaying 800X600 resolution. Do one of the following: – Click Yes and skip to page 38. – If you want to create a database without using the database wizard, click No to open the New Database dialog box.
Note This will create one 400 megabyte database partition and one file system partition composed of the remaining disk space. If you want to partition database devices with more complex partition configurations, follow the instructions on pages 138 to 141. c. Repeat steps a–b on additional devices. You can create up to three database partitions. d. Click the Create Database Mirror Set button. e. Click the Create Database button or the Load Database button to load a saved database.
The Database Wizard welcome screen appears. 5. 38 Click the Next button.

Using Device Groups A SAN Manager LM device group is a set of devices that are grouped into a logical set—for example, a JBOD, a department, or a computer room. With device groups, you can assign a set of devices to a host or share group, or identify all devices in the group. SAN Manager LM devices are stored in the default device group until you move them into a custom device group. Note The default device group name always includes the label [Default]. This part of the name cannot be changed or deleted.
Note 3. To name the devices in a group with sequential names based on the group name, right-click the device group and choose Name Devices As. For recommendations on device group, device, and volume naming, see page 151. Move devices into the group as described below. Moving Devices Between Groups • In the Storage pane, select one or more devices and drag them onto the destination device group’s icon.
Assigning Devices SAN Manager LM lets you assign devices to hosts or share groups without rebooting SAN hosts or storage systems.

This will unassign all of the devices that are assigned to that host or share group.
Reassigning Devices SAN Manager LM’s drag-and-drop capability lets you unassign devices from their current hosts and share groups and reassign them to other hosts or share groups. Reassignment Methods • To unassign one or more selected devices from one host or share group and assign them to another host or share group, drag the device(s) from the current host or share group onto the destination host or share group icon.
When you reassign devices, SAN Manager prompts you to confirm that you want to unassign the devices from their current host or share group and reassign them to the target host or share group. Do one of the following: – Click Yes or Yes to All to continue. If you click Yes, the reassignment warning message will appear for all devices that are being reassigned. If you click Yes to All, SAN Manager LM will reassign all of the selected devices with no additional device reassignment warnings.
Locking and Unlocking Devices SAN Manager LM’s shortcut menus allow you to lock and unlock devices. By default, all SAN Manager LM devices are unlocked. When a device is locked, you cannot partition the device, change its assignment status, or move it into another device group. Locking Devices • To lock all devices that are assigned to a host, right-click the host and choose Lock Devices. • To lock all of the devices in a device group, right-click the device group and choose Lock Devices.
Using Share Groups Share groups allow multiple hosts to use the same devices with read-write access. Hosts outside a share group cannot access share group devices. For general information on using share groups, follow the instructions below. For directions on using share groups with Microsoft Cluster Server, see pages 154–155. Share Group Restrictions • Hosts can be in one or more share groups. • Devices can be in only one share group at a time.

Storage Management Since SAN Manager LM storage is managed at the device (LUN) level, the application supports any partitioning format. You can partition and format devices before or after adding them to the SAN. When partitioning devices for use with SAN Manager LM, consider the following: • To partition and format devices with standard partitioning utilities, first assign them to the host you will use for partitioning and formatting.
SAN Storage Management About the Universal Partition Map (UPM) SAN Manager LM’s UPM is an operating system-independent partitioning format. UPM Partition Types SAN Manager LM’s partitioning utility allows you to create the following types of UPM partitions: Icon Partition Type Database partition: Used in the SAN Manager LM database mirror set. The recommended database partition size is 400 megabytes.
Partitioning Devices in SAN Manager LM • When you partition a device in SAN Manager LM, its partition map type is changed to the UPM format. Caution • Changing a partition map type will destroy all data on a disk. Modifying partitions in SAN Manager LM destroys data only on the partitions that are being modified. Partitioning a Device 1. In SAN Manager LM’s main window, the Database Wizard, the New Database dialog box, or the Database Mirror Set dialog box, double-click an unassigned device. 2.
SAN Storage Management The Device Partitions dialog box appears. Existing UPM partitions are listed in the Partitions pane. If there are no UPM partitions, the available disk space is listed as free space. 3. In the Partition Size text box, type the desired partition size in megabytes and press Enter or click Add Partition. Note If you are creating a database partition, the recommended size is 400 megabytes. The new partition appears in the Partitions pane with a file system icon: .
Note 5. SAN Manager LM’s partitioning utility supports up to 256 partitions per device. Windows NT only has 26 available drive letters, so when you assign UPM disks to Windows NT nodes, most applications can only access the same number of partitions as the number of available drive letters. When you create UPM partitions, they default to the file system partition type.
SAN Storage Management The Device Information dialog box appears. 8. Enter custom device information and click OK. If you do not want to customize the device information, click OK to close the dialog box.
Modifying UPM Partitions After partitioning a device in SAN Manager LM, you may want to resize file system partitions or change partition types. Increasing a Partition’s Size If there is free space listed after a file system partition in the Device Partitions dialog box, the file system partition’s size can be increased by adding some or all of the free space to it. 1. Double-click a UPM partitioned device in SAN Manager LM’s main window. 2. In the Device Information dialog box, click Edit Partitions.

If you want to edit more partitions, use the Apply button. The following warning appears: 5. Click Yes. 6. Do one of the following: – If you clicked OK in step 4, click OK to close the Device Information dialog box.
Formatting UPM Partitions When you assign a UPM partitioned device to a Windows NT host, all UPM file system partitions are listed with drive letters in Windows Explorer and My Computer. For instructions on using UPM devices with non-Windows NT hosts, see the SAN Manager LM Installation Guide for the appropriate operating system. Note When you assign a database device to a Windows NT host, the database partition is hidden by SAN Manager LM.
SAN Storage Management Formatting a UPM Partition Right-click the UPM partition’s drive listing in Windows Explorer or My Computer and quick format the partition or use the Command Prompt to format the partition. For more information on formatting disks, see your Windows NT documentation. Note You cannot partition or format UPM disks in Disk Administrator. UPM disks are displayed in Disk Administrator as foreign (UNIX) disks.
Erasing a UPM To re-partition a UPM disk with a standard partitioning utility, you need to erase the UPM. Note You cannot erase the UPM on a device that contains an active database mirror set device. To erase the UPM on a database device, first remove the device from the database (page 125). Erasing a UPM 1. Double-click an unassigned device to open the Device Information dialog box, or rightclick a device and choose Device Info in the shortcut menu. 2. Click the Edit Partitions button. 3.
SAN Storage Management Device Information Double-clicking a SAN Manager LM device opens the Device Information dialog box. On the left side of the Device Information dialog box, the text boxes with white backgrounds are customizable. The text boxes with gray backgrounds contain information that is automatically entered by SAN Manager LM. The following details are automatically entered by SAN Manager LM: • Name: The name of the device in SAN Manager LM.
• World Wide Name: The WWN of this device • LUN: The fields in the device’s SCSI-3 logical unit number. For more details about the information displayed here, see page 67.
SAN Storage Management Naming Conventions Assigned storage appears as local storage to SAN Manager LM hosts.When you assign a partitioned device to a host or share group, one or more separate partitions are listed by drive letter and volume label (if available) in Windows Explorer/My Computer on the host(s) with access. Volume labels are assigned when you format a device with Disk Administrator or with Windows NT’s Quick Format command.
Because this does not allow you to quickly make a connection between what you see in SAN Manager LM and what you see in Windows Explorer/My Computer, you may want to use a naming convention that ties together the device group, device, and volume labels.
6 ADVANCED SAN ADMINISTRATION Advanced SAN Administration Microsoft Cluster Server (MSCS) Using CLARiiON’s Application Transparent Failover (ATF) Using SAN Manager LM with the FC60 Storage Array Diskperf and Performance Monitor Ftdisk Disk Administrator Storage Management Software Replacing a Windows NT Domain Moving a Host from One SAN to Another Customizing the SAN Manager LM Installer Using SAN Manager LM’s Silent Install Mode SCSI Filter Drivers Configuring SAN Disks That Have No Active Logical Units
Microsoft Cluster Server (MSCS) The following information may be helpful when running SAN Manager LM with MSCS: • Use only Windows NT-partitioned (not UPM) storage as the quorum disk. • Use of a UPM logical device as the quorum disk is untested. SAN Manager LM encounters problems discovering logical devices if the physical devices are reserved by another host in the cluster.
• Advanced SAN Administration When using the HP SAN Manager LM QLogic HBA driver with Microsoft Cluster Server (MSCS) in a switched environment, set the BusResetBehavior registry value to 5, which enables bus reset operations to successfully break SCSI reservations, allowing successful cluster failover. A BusResetBehavior value of 5 enables target reset, LIP reset, and full login. For more information about the BusResetBehavior registry value, see page 188. Setting Up a MSCS Share Group 1.
Note SAN Manager LM devices cannot be unassigned while Cluster Server is running because Cluster Server’s drivers have claimed the devices. To unassign devices, shut down the cluster hosts or uninstall MSCS on the hosts, then unassign the devices in the SAN Manager LM administration application. You may need to re-apply current service packs after installing MSCS for the first time. See your Microsoft documentation for more information.
Using CLARiiON’s Application Transparent Failover (ATF) Advanced SAN Administration Setting Up ATF with SAN Manager LM includes the following steps: 1. Set up the Fibre Channel SAN Hardware 2. Install the Host Software 3. Discover LUNs on Both Storage Processors (SPs) 4. Assign Failover Pairs 5. Install ATF on Hosts that will use the RAID Set up the Fibre Channel SAN Hardware For hardware setup instructions, see page 21. Install the Host Software Install SAN Manager LM 1.
Registry Settings Caution Editing the registry incorrectly may cause serious problems that will require you to reinstall Windows NT. For more information about editing the registry, see your Microsoft documentation. On each host that will have access to the CLARiiON array, enter the registry settings in Table 1 and restart the host to activate the registry changes. Note If a registry path or value does not exist, create it. For instructions, see your Microsoft documentation.
Table 1 Registry Settings for ATF (cont’d) Path: Note The corresponds to the installed HBA driver. For example, for users with the HP SAN Manager LM QLogic HBA driver, the registry path is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ trqladrv\Parameters\Device[N] The number N appended to the path name is optional. It identifies the ScsiPort device instance (adapter) that the setting applies to.
Discover LUNs on Both Storage Processors (SPs) 1. Install CLARiiON’s Navisphere software on the host you will use to configure the CLARiiON array. 2. In SAN Manager LM, scan for devices to discover the active LUNs on the array’s SPs. 3. Confirm that all of the LUNs on the RAID are licensed and listed in SAN Manager LM’s main window. All of the active LUNs on both SPs should be listed. For example: Note Each device name lists the World Wide Name of its SP plus the LUN.
6. Using Navisphere, change the default SP assignment of each LUN. For example, change all LUNs on SP A to SP B, and change all LUNs on SP B to SP A. 7. Cycle power on the RAID to activate the change in SPs. 8. Start the SAN Manager LM administration application and scan for devices. Advanced SAN Administration The SAN Manager LM main window should now display the active LUNs and their missing peers. A LUN’s peer is a logical unit on the other SP that has the same logical unit number.
Tip To keep your devices organized in the main window, HP recommends creating a separate device group for all of the devices attached to each SP. Device group for SP A Device group for SP B 9. If desired, use Navisphere to redistribute the LUNs between the two SPs for normal operation. Assign Failover Pairs A failover pair consists of a LUN and its missing peer. 1. 162 Assign a LUN and its missing peer to a host that will be running ATF.
2. Tip After the LUN(s) and missing peer(s) are assigned, restart the host(s) to which they are assigned. Use the Event Viewer Log or bring up the ATF Console for any ATF program messages. Advanced SAN Administration Install ATF on Hosts that will use the RAID For instructions on installing ATF, see your CLARiiON documentation.
Using SAN Manager LM with the FC60 Storage Array SAN Manager LM for Windows NT can be used with HP FC60 storage arrays and the RDAC driver included with the HP Storage Manager 60-NT software. RDAC is an I/O path failover driver that is installed on host computers that access HP’s FC60. Typically, a pair of active controllers is located in a storage array. Each volume in the array is owned by one controller that provides the I/O path.
UPM file-system partitions may cause some confusion on the RDAC hosts to which they are assigned. In addition to the UNIX disks shown in Disk Administrator by SAN Manager LM’s disk driver, the RDAC disk driver will cause an offline device to display in Disk Administrator. However, this is expected and harmless behavior. • If you have an unwanted UPM partition on an FC60 LUN, unassign the LUN, erase the UPM partition map (page 148), and then reassign the LUN to the host.
Required Registry Settings Caution Editing the registry incorrectly may cause serious problems that will require you to reinstall Windows NT. For more information about editing the registry, see your Microsoft documentation. When running SAN Manager LM and RDAC the following settings are required on all hosts that are connected to the storage array. You can enter these registry settings through the Host Settings dialog box (page 182) or by using the Registry Editor.
Diskperf and Performance Monitor Advanced SAN Administration Diskperf (a filter driver) layers over disk drivers such as SAN Manager LM’s Disk Driver (trdisk). All disk I/O originating in higher-level drivers and applications passes through Diskperf, which collects performance statistics and reports them to the Performance Monitor application. Potential Problems • The filter driver is not loaded until it is enabled (diskperf -y) and the computer is restarted.
Ftdisk Ftdisk (Microsoft’s striping, mirroring, and volume-set driver) is a disk filter driver. Once a disk is enabled on a machine that is running Ftdisk, the device cannot be disabled until Ftdisk is stopped or the machine is shut down. This is because Ftdisk does not release its reference to the disk. Disabling a disk when there are active references to it could cause a computer to crash, so SAN Manager LM does not allow it.
If you create an invalid set in Disk Administrator, your computer may crash to a blue screen when you try to delete it. Caution Data loss or corruption can occur if you write data to an invalid set.
Disk Administrator Disk Administrator is the utility provided with Windows NT for managing disk partitions. It discovers the disks and partitions attached to the host on which it is running only at the time the program starts running. Disk Administrator does not hold disks open, and the View Refresh menu item does not actually detect the addition or removal of storage since the time Disk Administrator started.
Storage Management Software Advanced SAN Administration Software for configuring and managing storage devices such as RAIDs and tape libraries from Windows NT typically requires the capability of issuing SCSI commands to devices representing the hardware in question. When SAN Manager LM is installed on a SAN, these commands cannot be sent to such a device unless the device is assigned to the host on which the software is run.
Replacing a Windows NT Domain Note If you have a local group from a host included in your list of SAN Administration groups, you do not need to use the following procedure when replacing a domain. After replacing the domain, if you have a local SAN Administration group, run the SAN Manager LM administration application on the host with the local group. Choose administration groups from the new domain and remove administration groups from the old domain.
If you were unable to delete the database due to a domain controller failure, identify the database devices, if possible. This information will be used in step 4. 3. Replace the domain. 4. If the database could not be deleted due to a domain controller failure, disconnect the database mirror set device(s) from the SAN. 5. If you have a backup database file, restore it as described below.
Caution If you click Cancel before updating the administration groups, you will be locked out of SAN Manager LM and must start this procedure again with step 1. g. If you removed storage devices in step 4, continue with step 6. Otherwise, your database setup is complete. 6. Open the Device Information dialog box for the current database devices and write down the world wide name and logical unit number of each device, so they can be recognized in step 9. 7.
Moving a Host from One SAN to Another Unassign all storage from the host and remove the host from any share groups. 2. Stop the SAN Manager LM service on the host or shut the host down. 3. Make the cabling change to attach the host to a different SAN. 4. Restart the SAN Manager LM service or power up the host. 5. Using one of the methods on page 107, add the host to the database on the new SAN. 6. Delete the host from the original SAN database. For instructions, see page 108.
Customizing the SAN Manager LM Installer Some SAN Manager LM preferences are written into the registry by the installer. When you run the installer, it parses the file ModifiedInstall.txt and makes registry entries based on the contents of the file. The ModifiedInstall.txt file also allows you to specify installation settings such as the destination folder, and to set preferences for updating the registry, and installing the HP SAN Manager LM QLogic HBA driver and the administration application.
Using SAN Manager LM’s Silent Install Mode Advanced SAN Administration SAN Manager LM’s Silent Install feature allows users to run the installer with no required interaction. The silent install is performed by executing the setup.exe program from a command line with the -s flag, for example, setup.exe -s During the silent installation process, SAN Manager LM will create a log file reporting the status of the installation. The default log file is called setup.
SCSI Filter Drivers SAN Manager LM is not compatible with a class of drivers called SCSI filters unless SCSI filter compatibility mode is enabled. • Windows NT hosts operating in SCSI filter compatibility mode are subject to the following target and LUN limitations of the system SCSIPORT driver: 32 targets (0-31) per bus, 8 LUNs (0-7) per target. Note • This limitation varies depending on the installed Service Pack version and the registry setting for LargeLuns (page 181).
To optimize the interaction of SAN Manager LM and SCSIPORT, use the following settings: If the Update Windows NT registry for optimal SAN support option was selected during installation, the ScanDisconnectedDevices and LunRescan registry settings were automatically set up during installation. Caution Editing the registry incorrectly may cause serious problems that will require you to reinstall Windows NT. For more information about editing the registry, see your Microsoft documentation.
Configuring SAN Disks That Have No Active Logical Units Some devices present no active logical units when they are newly installed or otherwise un-configured. Previous versions (1.1 and earlier) of SAN Manager LM would not discover devices without active logical units, which meant the device could not be assigned to a host. As a result, the device management software could not communicate with the device to allow it to be configured.
Logical Unit Numbers Greater Than 7 Advanced SAN Administration When using disks in filter compatibility mode or non-disk devices such as tapes, SCSI bridges, and tape libraries regardless of mode, SCSIPORT’s restriction of eight LUNs per target (numbers 0–7) prevents SAN Manager LM and other applications and drivers from seeing devices with LUNs greater than 7. To configure SCSIPORT to support logical unit numbers greater than 7, use the LargeLUNs registry setting.
Registry Values for Customizing SAN Manager LM Caution Editing the registry incorrectly may cause serious problems that will require you to reinstall Windows NT. For more information about editing the registry, see your Microsoft documentation. Note Some of the registry keys listed in this section were installed during the SAN Manager LM installation. If a registry path or value does not exist, create it. You can specify some registry values during installation by using the ModifiedInstall.
