Display the maximum possible size of a LUN on a given volume or qtree.

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

Description

This command returns the maximum size of LUNs for different OS types in a volume or qtree. The command also includes possible maximum size for LUNs with Snapshots or without Snapshots. You can specify the path of the volume or qtree to determine the maximum size of a LUN that you want to create within that volume or qtree.

If you do not specify a path, the command returns the maximum LUN size for each OS type for all volumes and qtrees in a cluster.

The available space in a volume can change over time which means that the size reported by lun maxsize can change as well. In addition, the maximum LUN size allowed in a lun resize command may be less than the size reported by lun maxsize .
