Dell PowerVault ME5 Series Storage System CLI Reference Guide

Shows information about how the system is provisioned. This command shows the associations between controllers, disks, pools, volumes, and mappings. The command will show information for all associations by default, or you can use parameters to filter the output.

This command is useful for the following purposes:

• You want a quick overview of how the system is provisioned.
• You know of a disk-related issue (perhaps from the event log) and want to understand what components it may be impacting. You can use this command to see which volume WWNs are affected, which you can use on the host to determine which device node might be seeing errors.
• You know of a volume-level issue and want to determine which associated components to investigate. You can use this command to quickly see which controller owns the volume and which disks are associated with the volume. For example, perhaps at the OS level, a certain device node (target) looks “slow” relative to the rest of the targets. You can correlate the OS device node to the volume WWN (or LUN), and then use the command output to find the associated controller and disks.

Optional. Shows provisioning information for the specified list of disks. For disk syntax, see Command syntax. This command does not support the use of hyphens to indicate a range of disks.

Optional. Shows provisioning information for the specified list of LUNs.

Optional. Shows the Mapped field but no other mapping information. If this parameter is omitted, all mapping information is shown.

Optional. Shows provisioning information for the specified list of pools. A name that includes a space must be enclosed in double quotes.

Optional. Shows provisioning information for the specified list of ports. For port syntax, see Command syntax. This command does not support the use of hyphens to indicate a range of ports.

Optional. Shows provisioning information for the specified list of volumes. A name that includes a space must be enclosed in double quotes.

Optional. Shows provisioning information for pools whose health is not OK. If this parameter is omitted, provisioning information is shown for all pools.

Volume information:

• Volume name.
• Blank if the pool does not have a volume.

• Volume World Wide Name.
• Blank if the pool does not have a volume.

Owning controller of the pool.

Shorthand list of the disks within a pool.

Pool name.

• OK
• Degraded
• Fault
• N/A
• Unknown

Indicates whether the volume is mapped. This is useful when the no-mapping parameter is specified to hide detailed mapping information.

• Yes: The volume is mapped.
• No: The volume is not mapped.

Mapping information:

• Controller host ports that the mapping applies to.
• Blank if not mapped or mapped as no-access.

• LUN that identifies the volume to a host.
• Blank if not mapped or mapped as no-access.

Type of host access to the volume:

• read-write: The host has read and write access to the volume.
• read-only: The host has read access to the volume.
• no-access: The host is denied access to the volume.
• not-mapped: The host is not mapped to the volume.

• For an FC initiator, its WWPN.
• or a SAS initiator, its WWPN.
• For an iSCSI initiator, its node name (typically the IQN).

Host nickname.

• Standard: Default profile.
• HP-UX: The host uses Flat Space Addressing.
• OpenVMS: The initiator does not allow LUN 0 to be assigned to a mapping.

Standard: Default profile.
