End of Stack Trace
This problem happens on HP Integrity rx2600, rx3600, rx6600, BL860c systems, and on
rx7640 and rx8640 systems with AH303A adapters installed.
Corrective Action: Reboot the system to recover from the panic.
5 Recommendations
This section provides recommendations for highest performance and reliability.
• Updating Physical Disk Firmware
Consider the following when you use sasmgr(1M) to update the firmware of physical disks
that are part of a RAID volume attached to an HP 8 Internal Port SAS Controller:
◦ If you are updating the firmware on two or more disks that are part of a RAID volume,
do not issue multiple commands to download simultaneously.
◦ If the disk firmware download to a disk that is part of a RAID volume fails or is terminated,
reset the controller using the sasmgr(1M) reset command:
sasmgr -f reset -D /dev/sasdX
(Replace X with the instance of the SAS controller.)
• Swapping Spare Disks
Consider the following when you swap physical disks in a RAID volume controlled by an HP
8 Internal Port SAS Controller:
◦ Before swapping a spare disk, delete it using sasmgr(1M):
sasmgr delete -D /dev/sasdX -q raid -q spare
(Replace X with the instance of the SAS controller.)
After the new disk is installed, use sasmgr(1M) to configure the new disk as spare:
sasmgr add -D /dev/sasdX -q raid -q spare -q enc_bay=<enc>:<bay>
(Replace X with the instance of the SAS controller and <enc>:<bay> with the location
of the disk to be configured as spare.)
◦ By default, RAID volumes are created with Auto-Configure enabled. If you swap a physical
disk that is part of a RAID volume, a resync begins and data on the new disk is lost. Do
not insert a replacement disk unless you are sure that existing data is backed up.
