How to resolve volume changes for Auto Image Replication
When you open the Change Disk Pool dialog box, NetBackup loads the disk pool properties from the catalog. NetBackup queries the storage server for changes when you either click the button in the Change Disk Pool dialog box or when you configure a new disk pool for the storage server.
Veritas recommends that you take the following actions when the volume topology changes:
Discuss the changes with the storage administrator. You need to understand the changes so you can change your disk pools (if required) so that NetBackup can continue to use them.
If the changes were not planned for NetBackup, ask your storage administrator to revert the changes so that NetBackup functions correctly again.
NetBackup can process changes to the following volume properties:
If these volume properties change, NetBackup can update the disk pool to match the changes. NetBackup can continue to use the disk pool, although the disk pool may no longer match the storage unit or storage lifecycle purpose.
The following table describes the possible outcomes and how to resolve them.

No changes are discovered.
No changes are required.
NetBackup discovers the new volumes that you can add to the disk pool.
The new volumes appear in the Change Disk Pool dialog box. Text in the dialog box changes to indicate that you can add the new volumes to the disk pool.
The replication properties of all of the volumes changed, but they are still consistent.
A Disk Pool Configuration Alert pop-up box notifies you that the properties of all of the volumes in the disk pool changed, but they are all the same (homogeneous).
You must click Change Disk Pool dialog box are updated to match the new volume propertiesin the alert box, after which the disk pool properties in the
If new volumes are available that match the new properties, NetBackup displays those volumes in the Change Disk Pool dialog box. You can add those new volumes to the disk pool.
In the Change Disk Pool dialog box, select one of the following two choices:
The replication properties of the volumes changed, and they are now inconsistent.
A Disk Pool Configuration Error pop-up box notifies you that the replication properties of some of the volumes in the disk pool changed. The properties of the volumes in the disk pool are not homogeneous.
You must clickin the alert box.
In the Change Disk Pool dialog box, the properties of the disk pool are unchanged, and you cannot select them (that is, they are dimmed). However, the properties of the individual volumes are updated.
Because the volume properties are not homogeneous, NetBackup cannot use the disk pool until the storage configuration is fixed.
NetBackup does not display new volumes (if available) because the volumes already in the disk pool are not homogeneous.
To determine what has changed, compare the disk pool properties to the volume properties.
Work with your storage administrator to understand the changes and why they were made. The replication relationships may or may not have to be re-established. If the relationship was removed in error, re-establishing the relationships seem justified. If you are retiring or replacing the target replication device, you probably do not want to re-establish the relationships.
The disk pool remains unusable until the properties of the volumes in the disk pool are homogenous.
In the Change Disk Pool dialog box, click or to exit the Change Disk Pool dialog box.
NetBackup cannot find a volume or volumes that were in the disk pool.
A Disk Pool Configuration Alert pop-up box notifies you that an existing volume or volumes was deleted from the storage device:
NetBackup can use the disk pool, but data may be lost.
To protect against accidental data loss, NetBackup does not allow volumes to be deleted from a disk pool.
To continue to use the disk pool, do the following:
