What will happen when we swap the controller? Will the system just ask us to import the foreign config and we can retain the OS or will it require complete OS rebuild?
The HBA330 is not a RAID controller but and internal SAS HBA card which does not support RAID and as such will not posses any RAID information. Therefore, there will not be any foreign configuration to import. The option available is to backup existing data, install the H730 card, create Virtual Disks as necessary; re-install the OS and restore data from backup.
