lun mapping create

Map a LUN to an initiator group

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

Description

This command maps a LUN to all of the initiators in an initiator group (igroup). After you map the LUN, the LUN is visible to all initiators in the igroup.

Data ONTAP ensures that there are no LUN map conflicts whether the LUN is offline or online. A LUN map conflict is a mapping that would violate either of the following rules:

Note: Prior to mapping a LUN, you must have at least one iSCSI or FCP LIF provisioned on the LUN's owner node and high-availability partner node.

Parameters

-vserver <Vserver Name> - Vserver Name
Specifies the Vserver that contains the LUN you want to map.
{ -path <path> - LUN Path
Specifies the path of the LUN that you want to map. Examples of correct LUN paths are /vol/vol1/lun1 and /vol/vol1/qtree1/lun1.
| -volume <volume name> - Volume Name
Specifies the volume that contains the LUN you want to map.
[-qtree <qtree name>] - Qtree Name
Specifies the qtree that contains the LUN you want to map.
-lun <text>} - LUN Name
Specifies the LUN name that you want to map.
-igroup | -g <text> - Igroup Name
Specifies the igroup that you want to map.
[-lun-id <integer>] - LUN ID
Specifies the LUN ID for the mapping. The LUN ID is specific to the mapping, not to the LUN itself. This is used by the initiators in the igroup as the Logical Unit Number for the initiator when accessing the storage.
[-additional-reporting-node <nodename>] - Additional Reporting Node (privilege: advanced)
Specifies an additional node to populate the -reporting-nodes list when creating the LUN mapping. The specified node's high availability partner will be automatically populated as well. Use this parameter when preferred data mobility destinations are known ahead of time and the appropriate paths can be pre-configured.

Examples

cluster1::> lun mapping create -vserver vs1 -path /vol/vol1/lun1 -igroup ig1 -lun-id 8
