Need to move devices between DG's for a DR test
Hello all,
have an upcoming DR test that is only partial and the environment consists of several VMware farms. The issue is that only a few luns from each DG need to be tested and I was asked to created a new DG ( no issue) and move the luns/devices to be tested into that DG for testing.
Cannot find any way to move devices from one DG to another. Is there a way of doing this without taking them out of one DG (loosing synch and protection during this time) and placing them on the new group?
regards

Hello Rui,
Thanks for writing back. Yes, it can be done.
symdg -g move ld [-force] [-rename]
The above command can be used to move devices from one DG to another.
Refer the SE 7.5 command reference guide page 175 which documents this.
Does this answer you?

If you are looking to add some devices to a new DG while they are still present in the old DG.
To do so use the below command to add the device to the new DG:
symdg –g dg_name add dev xxxx –sid xxx
Note: For a device to be present in more than 1 DG at a given time, the parameter SYMAPI_ALLOW_DEV_IN_MULT_GRPS needs to be enabled. This parameter can be found in the OPTIONS file which is located at C:\Program Files\EMC\SYMAPI\config (default location).

Thanks for the answers but the issue would not be having the devices in more then 1 DG, but actually moving them between 2 dg's.
so for example device 1 /3 /4/5 /7 from vmware_dg being moved to dr_test_dg (only present in the second DG for a 1 week period after which they would be moved back to original DG)
Is this possible?

1) Devices can exist in multiple DGs. You need to enable an option in option file.
2) If its SRDF/A, then you cant run commands (like failover or split etc..) on few bunch of devices exist in same RA group.
3) You can change the SRDF mode to ACP and then perform the action on few bunch of devices.

Also just an FYI, moving a device out of a DG doesn't disrupt the sync on the device.
It does, however, mean that any commands issued against that DG will not be issued against the removed device.
