Most systems come equipped with a hardware RAID controller, which can be controlled from the OS when the right software is installed. There are a couple of flavours available, the one you need is not always obvious. The software can be used to destroy the RAID set, but more usefully it can be used to:
- manage the audible alarm (e.g. in case the backup battery unit is failing)
- blink the led of a disk that needs replacement
- enable/disable a disk
Installing the software
If it is not already installed, the software is available through the nikhef-external repo with yum. Use either of:
yum install MegaCli yum install storcli yum install MegaRAID_Software_Manager
MegaCli is a command-line tool with a rather painful syntax. Storcli is nicer.
/opt/MegaRAID/MegaCli/MegaCli64 -CfgDsply -aALL /opt/MegaRAID/storcli/storcli64 show all
In case these tools report no RAID controllers, try the StorCli from the last one:
/usr/local/MegaRAID\ Storage\ Manager/StorCLI/storcli64 show all
One of these should work.
