In this example, the virtual LDEV ID (0x2222) is assigned to the volume
whose actual LDEV ID is 0xfefe.

.
To use the virtual LDEV ID (0x2222) for a GAD pair volume, use the
raidcom unmap resource
command to remove assignment of the virtual
LDEV ID (0x2222) from the volume whose LDEV ID is 0xfefe.
raidcom unmap resource -ldev_id 0xfefe -virtual_ldev_id 0x2222 -

.
Confirm that the assignment of the virtual LDEV ID (0x2222) is removed
from the volume whose LDEV ID is 0xfefe.
raidcom get ldev -ldev_id 0x2222 -key front_end -cnt 1 -fx -IH101
When you specify the virtual storage machine for HORCM_VCMD in the
configuration definition file, and execute the
raidcom get ldev
command
by specifying the
-cnt
option, the virtual LDEV IDs existing in the
specified range by the
-cnt
option are displayed.
After you execute the above command, if the virtual LDEV ID 0x2222 is
not displayed, the same virtual LDEV ID (0x2222) as that of the primary
volume does not exist in the virtual storage machine of the secondary
site.
Note:
After releasing the virtual LDEV ID assignment, if you execute the
raidcom get ldev
command without specifying the
-cnt
option, the
following error code and message are output:
raidcom: [EX_EGPERM] Permission denied with the Resource Group
In the example above, the virtual LDEV ID (0x2222) has not been defined
after you released the virtual LDEV ID assignment. Therefore, the user of the
virtual storage machine does not have access authority.
When a command is executed specifying a virtual storage machine (that is,
using HORCM_VCMD), both the actual ID and the virtual ID of the specified
resource must be assigned to the user. When the virtual storage machine is
not specified (that is, using HORCM_CMD), the user can execute the
command only if the actual ID of the specified resource is assigned to the
user.
Creating a global-active device pair
When GAD configuration is complete, you can start creating GAD pairs. When
a pair is created, the P-VOL LDEV ID is set as the S-VOL's virtual LDEV ID.
When the paircreate operation completes, the pair status becomes PAIR, and
the P-VOL and S-VOL can accept I/O from the host. When a pair is deleted,
the S-VOL's virtual LDEV ID is deleted, and the GAD reservation attribute
remains set on the S-VOL.
Note:
When you create a GAD pair, make sure that the available pool
capacity for Dynamic Provisioning below the warning threshold is more than
the capacity of the secondary volume. If you create a GAD pair at the
secondary storage system when the available pool capacity below the
warning threshold is less than the capacity of the secondary volume, SIM
