VERITAS Storage Foundation 4.1 Intelligent Storage Provisioning Administrator's Guide

Chapter 4, Administering Application Volumes

Verifying the Intent of a Volume

1. Enter the following command to discover the task tag of the operation that you want to reverse:

# vxtask list

2. Use the task tag with this form of the vxtask command to stop the operation:

# vxtask abort task_tag

3. Finally, use the vxrelayout command to revert the volume to its former layout:

# vxrelayout [-g diskgroup] reverse volume

Note When mirrors are added or removed, ISP does not use the relayout or transform

operations internally. After adding a mirror to a volume, VxVM starts synchronizing the new

plexes from the existing plexes. In this case, the reverse operation can be performed by

removing the newly added plexes. To reverse the removal of a mirror, a new plex must be

added, and time allowed for it to be brought into synchronization with the volume.

Verifying the Intent of a Volume

To verify whether the application volumes in a disk group conform to the template rules,

user-defined rules, volume group rules and storage pool rules that were used to create them, use the

following command:

# vxvoladm -g diskgroup verify

To verify the intent of all application volumes in all disk groups, use this form of the command:

# vxvoladm -a verify

Displaying the Rules Associated with Objects

You can use the following command to display the rules that are associated with disk groups,

storage pools, plexes and volumes:

# vxvoladm [-g diskgroup] printintent [object_name ...]

If no objects are named as arguments, the command displays the rules that are associated with the

disk group.
