lun maxsize

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.

Parameters

{ [-fields <fieldname>, ...]
If you specify the -fields <fieldname>, ... parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.
| [-instance ]}

[-vserver <Vserver Name>] - Vserver Name
Specifies the Vserver.
{ [-path <qtree path>] - Volume or Qtree Path
Specifies the path of the root volume or qtree. Examples of correct volume and qtree paths are /vol/vol1 and /vol/vol1/qtree1.
| [-volume <volume name>] - Volume Name
Specifies the volume that contains the LUN you want to get the maximum size for.
[-qtree <qtree name>]} - Qtree Name
Specifies the qtree that contains the LUN you want to get the maximum size for.
[-ostype | -t <text>] - OS Type
Specifies the OS type for the new LUN. On an All SAN Array, the following OS types are supported:
  • hyper_v - the LUN will be used with Microsoft Hyper-V.
  • linux - the LUN will be used with Linux.
  • vmware - the LUN will be used with VMware VMFS.
  • windows - the LUN will be used with Microsoft Windows.
On all other clusters, the following OS types are supported:
  • hyper_v - the LUN will be used with Microsoft Hyper-V.
  • linux - the LUN will be used with Linux.
  • vmware - the LUN will be used with VMware VMFS.
  • windows - the LUN will be used with a Master Boot Record (MBR) partition table on Microsoft Windows 2003 or earlier.
  • windows_2008 - the LUN will be used with Microsoft Windows 2008 or later.
  • windows_gpt - the LUN will be used with a GUID Partition Type (GPT) partition table on Microsoft Windows.
  • xen - the LUN will be used with Xen
[-complete-ss-reserve <size>] - With Complete Snapshot Reserve
Shows the maximum size possible of a LUN if you have the complete Snapshot reserve enabled.
[-ss-reserve <size>] - With Snapshot Reserve
Shows the maximum size possible of a LUN if you have the Snapshot reserve enabled.
[-without-ss-reserve <size>] - Without Snapshot Reserve
Shows the maximum size possible of a LUN if you have no Snapshot reserve enabled.
