Modify qtree oplock mode

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

Description

This command allows you to display or modify the opportunistic lock mode of a qtree. This command is not supported on Infinite Volumes.

Parameters

-vserver <vserver name> - Vserver Name

This specifies the name of the Vserver on which the volume containing the qtree belongs.

{ -volume <volume name> - Volume Name

This specifies the name of the volume containing the qtree.

-qtree <qtree name> - Qtree Name

This specifies the name of the qtree for which the oplock mode is being displayed or modified.

| -qtree-path <qtree path> - Actual (Non-Junction) Qtree Path }

The qtree path argument in the format /vol/<volume name>/<qtree name> can be specified instead of specifying volume and qtree as separate arguments. The automatically created qtree0 can be represented as /vol/<volume name>.

[-oplock-mode {enable|disable}] - Oplock Mode

This specifies the new oplock mode of the qtree. If this parameter is not specified, then the current oplock mode of the qtree is displayed.

Modifying qtree0's oplock mode will not affect any of the files in the other qtrees of this volume.

Examples

The following example displays the oplock mode of a qtree called qtree1. The Vserver name is vs0 and the volume containing the qtree is named vol1.

cluster1::> volume qtree oplocks -vserver vs0 -volume vol1 -qtree qtree1
/vol/vol1/qtree1 has mixed security style and oplocks are disabled.
The following example modifies the oplock mode of a qtree called qtree2 to enabled. The Vserver name is vs0 and the volume containing the qtree is named vol1.
cluster1::> volume qtree oplocks -vserver vs0 -volume vol1 -qtree qtree2 -oplock-mode enable

The following example uses a 7G-compatible command to display and modify the oplock mode of a qtree.

cluster1::> vserver context vs0
vs0::> qtree oplocks /vol/vol1/qtree1
/vol/vol1/qtree1 has mixed security style and oplocks are disabled.
vs0::> qtree oplocks /vol/vol1/qtree2 enable
