Description
Shows information about all disks or disk slots in the storage system. The command will show
information about all installed disks by default, or you can use parameters to filter the output.
NOTE: In console format, to aid reading, disks are sorted to display in order by enclosure and disk
number. In API formats, output is not sorted because it is expected to be manipulated by a host
application.
