mpio_get_config Command

Purpose

Displays information about the DS3000 or the DS4000® subsystem that is based on multiple path I/O (MPIO) and the hdisks that are associated with the subsystem.

Syntax

mpio_get_config [ -v ] [ -a ] -A | -l <hdisk#> | -? | -h

Description

The mpio_get_config command displays information about the MPIO-based DS3000 or DS4000 subsystem and the hdisks that are associated with the subsystem.

Specifically, the command displays the information about the subsystem, including the assigned name of the subsystem, the worldwide name of the subsystem, and a list of hdisks in the Available state that are associated with the subsystem.

The following information about the hdisk# is displayed:
  • hdisk name
  • LUN number
  • Current ownership
  • Preferred path
  • Adapter information
  • User-assigned label for the volume

Flags

Item Description
-A Lists information for all attached subsystems.
-l Lists information for the subsystem that includes the hdisk that is specified by the hdisk# parameter.
-v Lists additional information about the controller and partition.
-a Lists the adapter information.

Parameters

Item Description
hdisk# Specifies the hdisk name.

Examples

  1. To display information about the subsystem that hdisk11 is a member of, enter the following command: 
    mpio_get_config -l hdisk11
    The system displays a message similar to the following message: 
    Storage Subsystem Name = 'Twister'

hdisk#           LUN #   Ownership          User Label
hdisk11              0   A (preferred)      1_disk_0
hdisk12              1   A (preferred)      1_disk_1
hdisk13              2   A (preferred)      1_disk_2
hdisk14              3   A (preferred)      1_disk_3
  2. To display the information about the subsystem that hdisk11 is a member of, along with the adapter information, enter the following command: 
    mpio_get_config -a -l hdisk11
    The system displays a message similar to the following message: 
    Storage Subsystem Name = 'Twister'
hdisk#           LUN #   Ownership           Adapter  User Label
hdisk11              0   A (preferred)        fscsi0  1_disk_0
hdisk12              1   A (preferred)      Inactive  1_disk_1
hdisk13              2   A (preferred)      Inactive  1_disk_2
hdisk14              3   A (preferred)      Inactive  1_disk_3
  3. To display information about all the attached subsystems, enter the following command: 
    mpio_get_config -A
    The system displays a message similar to the following message: 
    Storage Subsystem worldwide name: 60ab80026982e000045f255d7
Storage Subsystem Name = 'Twister'

hdisk#           LUN #   Ownership          User Label
hdisk11              0   A (preferred)      1_disk_0
hdisk12              1   A (preferred)      1_disk_1
hdisk13              2   A (preferred)      1_disk_2
hdisk14              3   A (preferred)      1_disk_3
  4. To display additional information about all the attached subsystems, enter the following command: 
    mpio_get_config -A -v
    The system displays a message similar to the following message: 
    Frame id 0:
Storage Subsystem worldwide name: 60ab80026982e000045f255d7
Controller count: 2
Partition count: 1
Partition 0:
Storage Subsystem Name = 'Twister'
hdisk#           LUN #   Ownership          User Label
hdisk11              0   A (preferred)      1_disk_0
hdisk12              1   A (preferred)      1_disk_1
hdisk13              2   A (preferred)      1_disk_2
hdisk14              3   A (preferred)      1_disk_3
