SerialSCSI-00 (sasd) B.11.31.1009 Mass Storage Driver Release Notes

Under the vPars I/O resource assignment rules, a host bus adapter cannot be shared among
multiple virtual partitions.
Corrective Action: None. This issue is corrected in vPars A.05.03 (B.11.31.0803).
• There is a setboot command issue on specific servers.
The setboot -p/-a/-h command fails when issued on an AH303A adapter installed in
slots 3 or 4 on HP Integrity rx3600 and rx6600 systems.
Corrective Action: Install AH303A adapters in nonswitched slots. This issue is corrected in
patch PHKL_37278.
4.3 All Controllers Supported by SerialSCSI-00
• Unnecessary reboot occurs when removing the sasd driver.
If you use swremove to remove the dynamically loaded sasd driver, the Critical Resource
Analysis (CRA) can fail. This causes the swremove command to incorrectly reboot the
system.
Severity: Low
Corrective Action: To avoid this CRA failure, before running swremove install patch
PHCO_36356 (or a superseding patch). Patches are available from the HP IT Resource Center
at:
http://itrc.hp.com/
Under “Maintenance and Support,” click the Patch Database link, then search for the patch
number. For more information on how to manage and install patches, see the Patch
Management User Guide for HP-UX 11.x Systems at:
http://www.hp.com/go/hpux-core-docs
NOTE: If you remove the dynamically loaded sasd driver while it is in use, or if you remove
the statically loaded sasd driver at any time, you must perform a reboot. This is normal
behavior under these conditions and is not affected by patch PHCO_36356.
• System panic when downgrading the sasd driver.
CAUTION: Installing an older version of the sasd driver downgrades the adapter firmware.
This can cause RAID volumes in the system to become degraded. HP recommends that you
back up important data before downgrading the adapter firmware.
If you install an older version of the sasd driver and version B.11.31.0712 is installed, the
system panics with the following stack trace:
panic: post_hndlr(): Unresolved kernel interruption
