Do not assign an access attribute to a volume if any job that handles data on the volume is running. If you assign an access attribute to such a volume, the job might end abnormally.
When the expiration lock is enabled, all volumes with the read-only and protect attributes cannot be changed to the read/write attribute even if the prohibition period for changing to the read/write attribute has elapsed. This setting applies to all volumes with the read-only and protect attributes on the storage system, not to each volume.
Prerequisites for changing the access attribute to read-only or protect :
- The Storage Administrator (Provisioning) role is required to perform this task.
- Verify that the volume must not meet the following conditions:
-
Volume that is not available
- Volume that is configured as a command device
- TrueCopy S-VOL*
- Universal Replicator S-VOL* or journal volumes
- ShadowImage S-VOL*
- Pool volume
- Deduplication system data volume
*The access attribute of the S-VOL might be changed depending on the pair status. For more information, see the user guide for each software product.
