- Check whether the same virtual LDEV ID as that of the P-VOL is assigned to the virtual storage machine in the secondary site. In this example, the virtual LDEV ID (0x2222) is assigned to the volume (actual LDEV ID: 0xfefe).
raidcom get ldev –ldev_list virtual –virtual_type 911111 RH20ETP -fx -IH1 LDEV# VIR_LDEV Serial# V_Serial# V_ID V_NUMBER VOL_TYPE VIR_VOL_TYPE SSID VIR_SSID AUTO_VIRTUAL_STORAGE fefe 2222 922222 911111 RH20ETP 1 OPEN-V-CVS OPEN-V-CVS a a YES 2223 2223 922222 911111 RH20ETP 1 OPEN-V-CVS OPEN-V-CVS a a NO
- If you use the virtual LDEV ID (0x2222) for a GAD pair volume, delete the volume.
raidcom delete ldev -ldev_id 0xfefe -operation initialize_capacity_saving -IH1
- Confirm that the volume has been deleted. Run the raidcom get command_status command to confirm the completion of the raidcom delete ldev command processing. Then, run the raidcom get ldev command to confirm that the volume has been deleted.
raidcom get command_status -IH1
raidcom get ldev -ldev_id 0xfefe -fx -IH1
- Re-create the volume by specifying the GAD reserve attribute -virtual_ldev_id reserve.
raidcom add ldev -pool 0 -ldev_id 0xfefe -capacity 1024000 -virtual_ldev_id reserve -capacity_saving deduplication_compression -drs -request_id auto -IH1 REQID : 100
Note:The maximum number of request IDs that can be assigned to a storage system is 65,280. If no request ID is available, the command fails with EX_IDEXHA. If this happens, release request IDs by referring to the description of request ID's functionality in the Command Control Interface Command Reference.
- Check the error information of the CCI configuration command that is performed asynchronously, by specifying the request ID displayed in step 4. Confirm that a hyphen (-) is displayed for Description.
raidcom get command_status -request_id 100 -IH1 REQID R SSB1 SSB2 Serial# ID Description 00000100 - - - 922222 - -
- After confirming that the asynchronous command is complete, release the request ID.
raidcom reset command_status -request_id 100 -IH1
- Confirm that the assignment of the virtual LDEV ID (0x2222) is released from the volume (LDEV ID: 0xfefe).
