Dell PowerVault ME5 Series Storage System CLI Reference Guide

Shows information about mappings between volumes and initiators. If no parameter is specified, this command shows information for all mapped volumes.

In a dual-controller system, if a mapping uses corresponding ports on both controllers, such as A1 and B1, the Ports field will simply show 1.

show maps

[all]

[initiator]

[<IDs>]

Optional. Shows mappings of all access types: read-write, read-only, no-access, and not-mapped (default mappings). If this parameter is omitted, mappings of type not-mapped are not shown.

Optional. Shows mapping information by initiator. If this parameter is omitted, mapping information is shown by volume.

Optional. A comma-separated list of the names or serial numbers of host-type items (initiators, hosts, and host groups) or volumes for which to show mappings. If a volume is mapped to a host group, to see mappings you must specify the host group, not a host or initiator in the group. If a volume is mapped to a host, to see mappings you must specify the host, not an initiator in the group.

You can specify:

• A host by name in the format <host-name>.*, where * represents all initiators in the host. Example: FC-Server.*
• A host group by name in the format <host-group>.*.*, where the first * represents all hosts in the group and the second * represents all initiators in those hosts. Example: TestLab.*.*

Serial Number

The serial number of the volume.

The name of the volume.

• The controller host ports to which the mapping applies.
• Blank if not mapped or mapped as no-access.

• The 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: Read and write.
• read-only: Read only.
• no-access: No access (masked).
• not-mapped: Not mapped.

Identifier

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

• For a host, its name in the format <host-name>.*, where the * represents all initiators in the host.
• For a host group, its name in the format <host-group>.*.*, where the first * represents all hosts in the host group and the second * represents all initiators in those hosts.
• Blank if not set or for all other initiators/

• 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.

ID

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