I am in a process of upgrading an EMC VNX5300. Have a RAID Group in DAE0_0 and the DAE is fully occupied with disks of this RAID Group plus Vault drives.
I just wonder if it is possible to add a new DAE and swap disks of mentioned RAID Group to the new DAE and Add up some HDDs and expand it later on?
I know this way we gotto ask for a down time. But we could have down-time for few hours.
