If you’ve migrated to a newer kernel and a newer hpsa module is used instead of cciss, you may wonder why you’re no longer able to use hpacucli tool to see the status of your RAID device:
If your RAID controller is similar to the one below (I’ve had it in ProLiant DL180 G6):
you may want to use these instructions:
- download and compile uname26 tool: http://mirror.linux.org.au/linux/kernel/people/ak/uname26/
- load sg module and try to run hpacucli again as below:
Other reported fixes:
- try the newest hpacucli
- use hpssacli instead of hpacucli
- make sure "sg" module is loaded (modprobe sg)
