AH303A PCIe SC44Ge SAS Host Bus Adapter for Integrity Servers Support Guide, September 2009

Recommendations
Updating Physical Disk Firmware
Consider the following when you update the firmware of physical disks attached to the AH303A
Host Bus Adapter with sasmgr(1M):
• If you are updating the firmware on more than one disk, do not issue multiple disk firmware
download commands on the same command line. Use individual commands for each disk
that is to be updated.
• If the disk firmware download is terminated, reset the controller using the sasmgr(1M)
reset comman:
sasmgr -f reset -D /dev/sasdX
(Replace X with the instance of the SAS controller.)
For example:
# sasmgr -f reset -D /dev/sasd0
Device (/dev/sasd0) has been RESET.
