Checking disk controller status using the CLI

You can use the command-line interface (CLI) to check the status of the system storage.

Issue lscontroller -delim : to display the example output:

id:controller_name:ctrl_s/n:vendor_id:product_id_low:product_id_high
0:controller0::IBM :1742-900:
1:controller1::IBM :2105800 :

You can also check the status of a specific disk controller. Issue the following command to check the status of a specific disk controller:

lscontroller -delim = controller_id

where controller_id is the ID of the controller whose status you want to check.

id=7
controller_name=controller7
WWNN=20000004CF2412AC
mdisk_link_count=1
max_mdisk_link_count=1
degraded=no
vendor_id=SEAGATE 
product_id_low=ST373405
product_id_high=FC      
product_revision=0003
ctrl_s/n=3EK0J5Y8
allow_quorum=no
site_id=2
site_name=DR
WWPN=22000004CF2412AC
path_count=1
max_path_count=1
WWPN=21000004CF2412AC
path_count=0
max_path_count=0
fabric_type=sas_direct

You can see the status of a specific disk controller (id=7) in the previous example. The value of degraded is defined below:

no: Specifies that the status is good
yes: Specifies that the status is undesirable
degraded: Specifies if the controller has degraded MDisks.
