HP Storage Platform 2.1 Release Notes

Hardware Monitoring
The following section describes workarounds for known hardware monitoring issues in the 9320 platform
• Hardware monitoring will continue to show a storage cluster in a DEGRADED state when an MSA
snapshot LUN is removed due to the reserve LUN getting full or the user removing the block
snapshot from an Ibrix 9320 Storage Platform. To resolve this issue, stop the monitoring process
via the “/etc/init.d/hpspmon stop” command. The monitoring process will be restarted
automatically and will reset the statuses.
• An HBA device driver issue can cause a kernel panic when reflashing any storage component on
the 9320 Storage Platform while monitoring is active or IO is still occurring. IO should be
suspended before the update, including all IO initiated by the HPSPMON monitoring subsystem.
IMPORTANT:
Storage disk drive update is an OFFLINE process.
• The pre-requisite measures to be followed before performing firmware update operation on
enclosures and enclosure hard disk drives are:Ensure that all host and array I/O must be stopped
prior to the update.
9. Make sure all the file-systems are un-mounted. Failure to comply may result in an OS
crashing.
10. Ensure that no other user is performing administrative functions on the storage system.
11. Ensure that the storage system configuration is not being reconfigured during a firmware
update.
12. To avoid spurious failure indications and potential system crashes, you must suspend
hardware monitoring during the update process. You should execute "hpspmonControl --
pause" on both servers in the couplet before performing the flash operation. You should
then make sure to execute "hpspmonControl --resume" on both servers in the couplet after
the flash operation is complete.
13. Do not cycle power or restart devices during a firmware update.

FRU Procedures
The following are known workarounds for some FRU replacement tasks:
• Before removing cables, switches must be first powered off. This detail will be added to our next
edition of the Field Repair Guide for the 9730.
• When the system board in a blade server is replaced, serial number, product ID and iLO
credentials (hpspAdmin account) for the HPSP monitoring software are lost and must be manually
restored to the new board. Also, the new system board has new Ethernet chips with different
MAC addresses than the system board it replaced. These values must be manually entered into
the ifcfg files as documented in the system Administration Guide. Follow these procedures to
perform these restoration tasks:
