I have a server running as an ESXI host that has a RAID card that is failing. But as the RAID is currently being used for datastores I am worried that replacing the RAID card will destroy all data on the drives.
My question is: If I replace the RAID card will the current RAID be recoverable or do I need to copy all data from the drives before replacing the card and rebuild the RAID from scratch?
The current server is a HP server and could replace the RAID card, but also have a spare Dell server that is ESXi hosted already and could just swap the drives out. But thinking that changing makes of servers/RAID controllers will destroy the RAID array.
Any help with this urgent issue is greatly appreciated.
