Display a list of LUNs on the given array

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The storage array disk paths show command displays information about disks and array LUNs. Where it appears in the remainder of this document, "disk" may refer to either a disk or an array LUN. By default, the command displays the following information about all disks:

  • Disk Unique Identifier

  • Controller name

  • Initiator Port

  • LUN ID

  • Failover optimization type

  • The Use State of the LUN on this path

  • Target Port

  • Target IQN

  • TPGN

  • Port speeds

  • Kbytes/sec on Disk (Rolling Average)

  • Number IOPS per second on disk (Rolling Average)

To display detailed information about a single disk, use the -disk parameter.

Parameters

{ [-fields <fieldname>,…​]

Displays the specified fields for all disks, in column style output.

| [-switch ]

Displays the switch port information for all disks, in column style output.

| [-instance ] }

Displays detailed disk information. If no disk path name is specified, this parameter displays the same detailed information for all disks as does the -disk parameter. If a disk path name is specified, then this parameter displays the same detailed information for the specified disks as does the -disk parameter.

[-uid <text>] - Disk Unique Identifier

Selects the disks whose unique id matches this parameter value. A disk unique identifier has the form: `20000000:875D4C32:00000000:00000000:00000000:00000000:00000000:00000000:00000000:00000000 `

[-disk <disk path name>] - Disk Name

Displays detailed information about the specified disks.

[-array-name <array name>] - Array Name

[-nodelist {<nodename>|local}] - Controller name

Selects information about disks that are visible to all of the specified nodes .

[-initiator <text>,…​] - Initiator Port
