Listing MDisks using the CLI

You can use the command-line interface (CLI) to list the MDisks.

1. Issue the following CLI command:

   lsmdisk delim :

   The following output is an example of what you might see when you issue the lsmdisk delim : command:

   id:name:status:mode:mdisk_grp_id:mdisk_grp_name:capacity:ctrl_LUN_#:controller_name:UID
   0:mdisk0:online:unmanaged:::68.4GB:0000000000000000:controller0*
   1:mdisk1:online:unmanaged:::68.4GB:0000000000000000:controller1+
   2:mdisk2:online:unmanaged:::68.4GB:0000000000000000:controller2++
   3:mdisk3:online:unmanaged:::68.4GB:0000000000000000:controller3
   4:mdisk4:online:unmanaged:::68.4GB:0000000000000000:controller4#

2. View the status column to determine the status of the MDisk. In this example, all the MDisks have a status of online. The following list shows the possible status of an MDisk:
   • Online
   • Offline
   • Excluded
   • Degraded ports
   • Degraded paths
3. View the mode column to determine the mode of the disk. In this example, the mode is unmanaged. The following list shows possible modes for an MDisk:
   • Managed
   • Unmanaged
   • Image
4. You can also list more detailed information about an MDisk. For example, issue the lsmdisk delim : 3 command to see detailed information about the MDisk with an ID of 3. The following output is an example of what you might see:

   id:3
   name:mdisk3
   status:offline
   mode:managed
   mdisk_grp_id:3
   mdisk_grp_name:SSD3

   spare_goal:2

   balanced:yes
   tier:generic_ssd
   site_id:3
   site_name:Quorum

   Note: If the selected MDisk is a flash drive, the node ID, node name, and node location attributes contain values.
