Can i move disk from RG1 to RG2 on va7410?

Hello. I have va 7410 disk array.
RG1 have 100 Mb free and RG2 have 20 Mb free.
I want to balance free capacity and move one disk from RG1 to RG2 (move disk from slot 9 to slot 12). Can i do it?
What actions i must do and where can i read about it?

Remove one disk. Let the rebuild complete without error â watch the armdsp output. Re-install the disk in the new RG. You must let the rebuild complete, else the controller will use the disk in the old RG.

Also, removing a disk induces a failure. The array is now exposed to a second failure. Having a backup of your data would be a good safety net. Also, review the logprn data for the last completion of Scrub. If Scrub has completed in the recent past, then it is unlikely that there are any latent parity errors

When you have data on the array it will not let you down a disk without using a "force" parameter. You can just pull the disk out, watch for the rebuild to complete and then insert it in the other RG. Be sure the rebuild has complete or you will have a warning state "disk in wrong RG"...
