Identifying drives

When identifying drives, there are other optional parameters that you can include to narrow the scope of

the drives to obtain information from. You can identify drives from the adapter (all down-chain

enclosures attached to a specified HBA), all the drives in a specific enclosure, or all the drives in a

specified drawer in a specified enclosure. To get information about all the drives visible to an adapter, run

the following command:

To get information about all the drives on the machine:

shmcli list drives

To get information about all the drives visible to an adapter:

shmcli list drives -a=<(SASAddress | AdapterIndex)>

For all the drives visible to an adapter:

To get information about all the drives in a specific enclosure:

shmcli list drives -a=<(SASAddress | AdapterIndex)> -enc=<(WWN | EnclIndex)>

Output

For all the drives in a specific enclosure:

To get information about all the drives in a drawer within an enclosure:

shmcli list drives -a=<(SASAddress | AdapterIndex)> -enc=<(WWN | EnclIndex)> -

w=<DrawerIndex>

Output

For all the drives in a drawer within an enclosure:

The relevant information to record from the list drives command are the Enclosure Slot Index and

the WWN. These values are required to perform actions on a specific drive such as updating the firmware

or making the LED of a drive to blink for identification purposes.
