HP Surestore SAN Manager DM Software, Surestore SAN Manager LM Software manual Known Issues

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

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.

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.

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