storage array disk paths show

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)

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

[-target-port-access-state <text>, ...] - Failover optimization type

Selects information about disks visible on target ports that have the specified access state.

[-initiator-io-kbps <integer>, ...] - Kbytes of I/O per second on Initiator (Rolling Average)

Selects information about disks visible to an initiator that has executed I/O at the specified throughput.

[-initiator-iops <integer>, ...] - Number of IOPS on Initiator (Rolling Average)

Selects information about disks visible to an initiator that has executed the specified number of IOPs.

[-target-io-kbps <integer>, ...] - Kbytes of I/O per second to Target (Rolling Average)

Selects information about disks visible on target ports that have reached the specified I/O throughput.

[-target-iops <integer>, ...] - Number of IOPS to Target (Rolling Average)

Selects information about disks visible on target ports that have performed the specified number of IOPs.

[-path-link-errors <integer>, ...] - Link Error count on path

Selects information about disks with paths that have incurred the specified number of FC link errors.

[-path-io-kbps <integer>, ...] - Kbytes of I/O per second on Path (Rolling Average)

Selects information about disk with paths that have reached the specified I/O throughput.

[-path-iops <integer>, ...] - Number of IOPS on Path (Rolling Average)
