HOWTO

Add new/replacement disk

Show all should tell you s(Slot), dg, array and row, then:

storcli /c0/e32/s12 insert dg=0 array=0 row=0
storcli /c0/e32/s12 start rebuild

Locate a disk

storcli /c0/e8/s2 start locate

Show rebuild status

storcli /c0 /eall /sall show rebuild

Drive mappings

sg_map -x

Output: /dev/sgXX <host_number> <bus> <scsi_id> <lun> <scsi_type>

TODO find out where that '7' comes from
