Replace the bad drive and let = Promise rebuild is one way. Promise RAID card does automatic rebuild = after an array failure. Usually why you boot up the server, Promise BIOS will say whether the = Array is FUNCTIONAL or FAILURE. You can also temporarily go to single mode and mount the drives manually = with ar1 instead of ar0 Tamouh
