Determine whether LSI9361 drives are present
To determine whether LSI9361 drives are present perform the following steps:
- To list SCSI hosts, run the lsscsi command. Check for the
megaraid_sas
string in the output.localhost:~ # lsscsi --hosts [0] aacraid [1] megaraid_sas [2] mpt3sas [3] qla2xxx [4] mpt3sas [5] qla2xxx localhost:~ #
- For each controller, that is, for each SCSI host, run the storcli64 command
from
Broadcom
driver to check the drives that are attached to each controller. The storcli64 command numbers the controllers starting with 0, for example /c0, /c1 and so on.localhost:~ # storcli64 /c0 show ...

Notes:- Since the output can be long, consider only the
PD LIST
section. Only drives in theUGood
state can be erased, and such drives are not accessible from the OS. If the drive is part of a RAID volume, or shown as a JBOD, it must be disconnected from the volume or OS. - The
Med
column indicates whether a drive is rotational (HDD) or solid-state (SSD). TheSED
column indicates the presence of SED drives if it has value of Y. The PI column indicates whether the drive is using T10-Protection Information. - Use the data from the
EID:Slt
column as a value for the/ex
and/sx
parameters in the erase commands.
