Locating a solid-state drive (SSD) using the CLI

You can identify the node slot that a solid-state drive (SSD) is located in using the SAN Volume Controller CLI.

1. To locate an SSD, run the following command :

   svcinfo lsmdisk mdisk_name | mdisk_id

   Where mdisk_name | mdisk_id is the name or ID of the MDisk that is an SSD.

   Output is similar to the following example. The node_id and node_name fields identify the node that the SSD is installed in. The location field indicates the drive slot that the SSD is located in. If the field is blank, the MDisk is not an SSD in a SAN Volume Controller node.

   id 0
   name mdisk0
   status online
   mode managed
   mdisk_grp_id 1
   mdisk_grp_name ssd_n1
   capacity 136.7GB
   quorum_index
   block_size 512
   controller_name controller0
   ctrl_type 6
   ctrl_WWNN 5005076801E00047
   controller_id 0
   path_count 1
   max_path_count 1
   ctrl_LUN_# 0000000000000000
   UID 5000a7200000839100000000000000000\
   0000000000000000000000000000000
   preferred_WWPN 5000A72A00008391
   active_WWPN 5000A72A00008391
   node_id 1
   node_name node1
   location 2

2. Run the following command to list additional details about the SSD, including the serial number and firmware level.

   svcinfo lsnodevpd node_name | node_id

   Where node_name | node_id is the name or ID of the node that contains the SSD.

   Output is similar to the following example. The drive_location identifies the specific SSD that is listed:

   drive_location 2
   manufacturer IBM
   model Z16IZD2B-73
   capacity 00014337400
   serial_number S092901FG008
