Specify an LDEV ID whose virtual attribute with GAD reserve assigned to create a volume that is used as the S-VOL of the GAD pair. The capacity of the volume must be the same as the P-VOL.
-
Verify the capacity of the volume used as the P-VOL of the GAD pair on the
primary storage system.

- Create a virtual volume (DP-VOL) with a capacity of 1,024,000 blocks and an LDEV ID of 0x4444 in the Dynamic Provisioning pool with a pool ID of 0. If you perform VSM auto-configuration, specify the GAD reserve attribute (-virtual_ldev_id reserve).
Command example for VSM auto-configuration:
raidcom add ldev -pool 0 -ldev_id 0x4444 -capacity 1024000
-virtual_ldev_id reserve -capacity_saving deduplication_compression
-drs -request_id auto -IH1 REQID : 100
Command example for VSM manual configuration:
raidcom add ldev -pool 0 -ldev_id 0x4444 -capacity 1024000 -capacity_saving deduplication_compression -drs -request_id auto -IH1
REQID: 100
Note: A maximum of 65,280 request IDs can be assigned to one storage system. If there is no available request ID, the command fails with EX_IDEXHA. If that occurs, see the description of the function of request IDs in the Command Control Interface Command Reference and release request IDs.
- Specify the request ID that was displayed in step 2, and then check the error information about the CCI configuration command that is performed asynchronously. Verify that the value in the Description column is a hyphen (-).

Check command and output examplesDisplay the information about the volume (LDEV ID: 0x4444).
Verify that the created volume meets the following requirements:
- The GAD reserve is assigned to the virtual attribute.
- The volume has the same capacity as the P-VOL.
- The volume is a DP-VOL.
