A client has a very old server with a failed SAS 5iR controller. The post don't show information regarding the SAS controller's configuration, just errors.
I want to back up the data on the server and build a new one.
Since it has a RAID1, If I remove one disk from the array and connect it to a new controller, would it be possible to boot / read the contents to make a backup?
As long as the "new" controller is a SAS 5/iR or SAS 6/iR, it will recognize the RAID formatting and be able to use the existing configuration and read the data.
