• Virtual Partitions do not boot if hardware reconfiguration changes the hardware path
under vPars A.4.05.
Virtual Partitions (vPars) using an HP StorageWorks MSA50/MSA60/MSA70 enclosure do
not boot if hardware paths change due to hardware reconfiguration. For more information
on the impacts of hardware reconfiguration, see the Ignite-UX and SAS Devices white paper
at:
http://docs.hp.com/en/oshpux11i.html
Corrective Action: This issue is corrected in vPars A.04.06 (B.11.23.0809).
• 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_37869. You can download patches from the IT Resource Center at:

• System panic when downgrading the sasd driver.
CAUTION: Installing version B.11.23.0712 or earlier of the sasd driver downgrades the
adapter firmware. This can cause RAID volumes in the system to become degraded. Back
up important data before downgrading the adapter firmware.
If you install an older version of the sasd driver and version B.11.23.0712 is installed, the
system panics with the following stack trace:
panic: post_hndlr(): Unresolved kernel interruption
