Problem
Track Alignment may not work correctly in Storage Foundation for Windows 5.0.
Solution
Track Alignment
is enabled, but not enforced for an array with Track Alignment settings
configured in Storage Foundation for Windows (SFW) 5.0.
Conditions:
- The array is listed in the SFW Veritas Enterprise Administrator (VEA) User Interface -> Control Panel -> Track Alignment Settings dialog.
- Track Alignment is enabled in the same dialog.
- The Vendor ID and Product ID of the Disk does not exactly match the Vendor ID and Product ID listed in the Track Alignment Settings dialog.
Cause:
The Track
Alignment feature works by comparing the Vendor and Product ID read from the
disks (array) against a static list; as seen in the VEA - Control Panel -
Track Alignment Settings dialog. Most arrays have a static Vendor and
Product ID; however, there are instances where this can change. An example is
where the ProductID "RAID" can also be "RAID_5".
Affected
Registry Hives:
64-bit Server:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Veritas\VxSvc\CurrentVersion\VolumeManager\TrackAlignment]
32-bit Server:
[HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\VxSvc\CurrentVersion\VolumeManager\TrackAlignment]
Answer/Resolution:
An update is
available by clicking on the Download Now link below. Please note that this
update stops and restarts the Veritas Storage Agent (vxvm). This will cause
clustered resources to fault. It is recommended to move any clustered resources
to other nodes prior to running this patch.
1. Download the
attached binary (1125275_293232.exe) and extract to a temporary
folder
2. Change to
the 32 or 64 Folder depending on the version of Windows (32/64
bit)
3. Run
"SFW50-TAV-Registry-Update.cmd" from the temporary folder
Note:
This update also adds Track Alignment support for the Pillar Axiom 300 and 500
series. Following installation of the update, Track Alignment will be set to
Enabled.
Note:
This technote supersedes technote 292352
