lun modify

Modify a LUN

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

Description

This command modifies LUN attributes. Because LUN modifications can result in data corruption or other problems, we recommend that you call technical support if you are unsure of the possible consequences of modifying a LUN.
Note:

Parameters

-vserver <vserver name> - Vserver Name

Specifies the Vserver.

{  -path <path> - LUN Path

Specifies the path for the LUN you want to modify. Examples of correct LUN paths are /vol/vol1/lun1 and /vol/vol1/qtree1/lun1.

|  -volume <volume name> - Volume Name

Specifies the volume for the LUN you want to modify.

   -qtree <text> - Qtree Name

Specifies the qtree for the LUN you want to modify.

   -lun <text>  } - LUN Name

Specifies the name for the LUN you want to modify. A LUN name is a case-sensitive name and has the following requirements:

[-space-reserve {enabled|disabled}] - Space Reservation

Specifies whether the space reservation setting is enabled or disabled for a LUN. If you set the parameter to enabled, the LUN is space-reserved. If you set the parameter to disable, the LUN is thinly provisioned. The default is enabled.

[-serial <text>] - Serial Number

Specifies the serial number for the LUN you want to modify.

[-comment <text>] - Comment

Specifies the comment for the LUN you want to modify.

[-space-allocation {enabled|disabled}] - Space Allocation

Specifies whether space allocation is enabled or disabled for a LUN. If you set this parameter to enabled, space allocation is enabled and provisioning threshold events for the LUN are reported. If you set this parameter to disabled, space allocation is not enabled and provisioning threshold events for the LUN are not reported. The default is disabled.

[-state <lunState_enum>] - State

Specifies the administrative state of a LUN. The options are:

{  [-device-legacy-id <integer>] - Device Legacy ID

Specifies the device legacy ID for the LUN you want to modify.

|  [-device-binary-id <text>] - Device Binary ID

Specifies the device binary ID for the LUN you want to modify.

|  [-clear-binary-id [true]]  } - Clear Device Binary ID

Clears the binary format of the optional device ID.

{  [-device-text-id <text>] - Device Text ID

Specifies the device text ID for the LUN you want to modify.

|  [-clear-text-id [true]]  } - Clear Device Text ID

Clears the text format of the optional device ID.

[-qos-policy-group <text>] - QoS Policy Group

This optionally specifies which QoS policy group to apply to the lun. This policy group defines measurable service level objectives (SLOs) that apply to the storage objects with which the policy group is associated. If you do not assign a policy group to a lun, the system will not monitor and control the traffic to it. To remove this lun from a policy group, enter the reserved keyword "none".

Examples

cluster1::> lun modify -path /vol/vol1/lun1 -space-reserve disable

Disables the space reserve attribute for LUN /vol/vol1/lun1.

cluster1::> lun modify -path /vol/vol1/lun1 -state offline 

Takes the LUN /vol/vol1/lun1 offline.

cluster1::> lun modify -path /vol/vol1/lun1 -comment "new comment"

Adds the comment "new comment" to the LUN /vol/vol1/lun1.
