Veritas Volume Manager 5.1 SP1 Release Notes HP-UX 11i v3 (5900-1518, August 2011)

Workaround
If Virtual I/O (VIO) is used, switch to Accelerated Virtual I/O (AVIO). If problem still persists,
use a non-VxVM disk as the boot disk. Patch will be released in future to fix this issue.
• Problem
In rare cases, the system may panic with the following stack trace:
panic: all VFS_MOUNTROOTs failed: RDWR
Stack Trace:

End of Stack Trace
Workaround
Rebooting the system may fix the issue.
• Problem
After installing VxVM 5.1 SP1, the following message may be displayed on the console:
"hpalua claim_device: preferred bit is not set for the device
/dev/rdsk/c23t1d2.Please refer the document Storage Foundation
Hardware Technote for the same."
This message may be displayed for all the LUNs present on the system. It is generated because
the Preferred path/mode is not set for the LUNs.
Workaround
Using Command View, set the Preferred path/mode to [Controller A/B -
Failover/Fail-back] instead of the default [No Preference] .
• Problem
VxVM disk groups with a disk group version of 160 cannot be restored using Ignite-UX version
C.7.12.
Archive creation (when disk groups with a disk group version of 160 are present on the system)
does not display any error/warning indicating restore operation will fail.
Workaround
Use the selective archival feature provided by Ignite-UX to archive only the disk groups with
a disk group version less than 160. For more information, refer to the Ignite-UX Administration
Guide for HP-UX 11i, March 2011.
Future versions of Ignite-UX may support archive/restore operations of VxVM disk groups with
a disk group version of 160 or above.
For the most up-to-date information on the Ignite-UX product, refer to the latest version of the
Ignite-UX Release Notes HP-UX 11i.
