IBM SAN Volume Controller plug-in considerations and limitations
The following considerations and limitations are applicable:
NetBackup disables vDisk protection to perform the deport and delete operations on the array when these operations are initiated, and then it reverts to the original state. These operations do not have any impact on any existing mapping or I/O operations performed on the array.
During restore the standard warning shown on the array regarding FlashCopy mappings is considered as a warning. NetBackup restores the volume irrespective of the warning, as similar behavior is observed on the array side.
Do not delete the mappings created between the source and target volumes. If any mapping between the source and target volume is deleted, then the snapshot becomes invalid and NetBackup operations are not performed.
Do not delete the mappings between the source and the target volumes because the snapshot is not restored on the source volume.
The copying operation of any FlashCopy mapping must not be interrupted in any case.
The mapping between the source and target volume in the consistency group snapshot should not be deleted. If any mapping between the source and target volume is deleted, that source volume is not restored as it is not the part consistency group snapshot.
