HP Surestore SAN Manager DM, Surestore SAN Manager LM Release Notes

SAN Manager LM 1.2 for Windows NT Release Notes

New In This Release

OFTWARE

SAN Manager LM is compatible with Windows NT 4.0 with Service Pack 4 or later. However, due to the limitations discussed in the first paragraph under Known Issues on page 3, HP recommends Service Pack 6a.

ARDWARE

With the release of version 1.2, SAN Manager LM now supports the following hardware:

RAIDs

– EMC Symmetrix 3000 Devices (SCSI)

– HP SureStore E Disk Array XP256 (SCSI)

Note

– HP SureStore E Disk System FC60 with version 7.02.27.01 or later of the RDAC driver

OMPATIBILITY

EMC Symmetrix 3000 (SCSI) devices and XP256 (SCSI) devices are only compatible with SAN Manager LM when they are configured with a Crossroads bridge and QLogic HBAs.

UALIFIED

The following HBAs are the only HBAs that are qualified for use with SAN Manager LM on Windows NT hosts:

– QLogic QLA2100 and QLA2200 with the HP SAN Manager LM QLogic HBA driver

HBA

For an up-to-date list of the HBAs and drivers that are qualified for use with SAN Manager LM, visit HP’s Customer Care website. For more information about the Customer Care website, see the Obtaining Free HP Product Information document that is included in your SAN Manager LM box.

QLogic HBA Issues

– The BIOS must be disabled on the HBA. Failure to disable the BIOS can result in unstable operation

and compromised storage.

– The HP SAN Manager LM QLogic HBA driver (trqladrv.sys) does not support hot-plugging. You cannot

insert an HBA card into a computer that is powered on.

– If you choose not to install the HP SAN Manager LM QLogic HBA driver during the SAN Manager LM

installation procedure, and later you decide to use the HP SAN Manager LM QLogic HBA driver, you must uninstall and then reinstall SAN Manager LM.

EATURES

SAN Manager LM-Ready Filter Driver – A standard filter driver for FCCI (Fibre Channel Common

Interface) compliant HBA drivers has been included in SAN Manager LM. This filter driver provides support for qualified off-the-shelf HBA drivers from other HBA vendors.

LUN Identification – LUNs that are related (same unit of storage with a different WWN) can now be

identified through SAN Manager LM’s device shortcut menu. This capability simplifies the management of multi-ported RAIDs that present duplicate LUNs on more than one port for high availability and other purposes.

Drag-and-Drop Discovery – A new method has been provided for the discovery of hosts on Windows NT

networks. The SAN Manager LM administrator can now invoke discovery on selected hosts or a branch of the Windows NT Network Neighborhood tree by selecting the items and dragging them into the main window of the SAN Manager LM administration application.

Device Locking – Inadvertent changes to devices can now be prevented by the device locking feature. A

locked device cannot be assigned, unassigned, moved to another device group, or re-partitioned.

THER

Host Information Dialog Box – This dialog box provides information about the installed operating

system and SAN Manager LM components on a selected host.

Note

NHANCEMENTS

When viewing the host information of hosts that are running SAN Manager LM 1.1.1 and earlier, the dialog box lists only the host ID and SAN Manager LM service version.

This feature is currently supported on Windows NT hosts only.

Host Settings Dialog Box – This dialog box allows users to view and change host-specific SAN Manager

LM settings without using tools such as the Windows NT Registry Editor.

Note

This feature is currently supported on Windows NT hosts only.

Silent Install – A hands-off (automated) method for installing SAN Manager LM is available to reduce

installation time on multiple hosts. Command-line flags and an install text file control the silent installation process.

Database Wizard – A database wizard has been added to guide administrators through the SAN Manager

LM database creation process.

Remove License – Reconfiguration of multiple SANs has been simplified by the remove license feature. It

is now possible to remove a SAN Manager LM license key without removing the database on the source SAN.

SCSI Address Decoding – The device information dialog box now provides information on the type of

SCSI addressing used, and decodes the address bits for easier viewing. This information can also be appended to the device name in the main window of the SAN Manager LM administration application. This feature is valuable for analyzing configurations with devices that use different SCSI addressing modes.

Assignment Warning Message – A warning message is displayed when the administrator tries to assign

unpartitioned storage or storage with an incompatible partition map format to a host (e.g., when a Windows NT-formatted disk is assigned to a Solaris host).

Note

Numbered Error Dialogs – SAN Manager LM error dialog boxes are now numbered so support engineers

can easily identify them after product localization.

Windows NT Event Log – More SAN Manager LM error conditions are now reported in the Windows NT

Event Log.

Enhanced Online Help – What’s This? help is now available in the main window of the SAN Manager LM

administration application.

No assignment warning is displayed when you assign an unpartitioned device to a share group.

Known Issues

On Windows NT hosts with service packs prior to Service Pack 6, the system SCSI port driver

•

(SCSIPORT) may leak hundreds or thousands of handles each time a bus rescan is performed. When the SAN Manager LM administration application assigns one or more LUNs to a Windows NT host, the SAN Manager LM service (TRSANManService.exe) triggers a bus rescan. The result is that the leaked handles are attributed to the service’s open-handle count, which will continue to grow until it interferes with the service’s functionality. Further, when a LUN is assigned to a host, but the host cannot contact that LUN, the SAN Manager LM disk driver (TRDISK.SYS) will periodically trigger a bus rescan so it can try again to contact the LUN. As long as the missing LUN is assigned to the host, periodic rescans will continue to cause handle leaks. These handles are attributed to the system process rather than the SAN Manager LM service. This means that the open handle count for the system process will continue to grow until it eventually interferes with correct system operation.

The number of handles open in a process can be observed on the Processes tab page in the Task Manager utility.
