Post-failure recovery like you mention is possible too, but this way is easier. A spare can be added either via the BIOS or the CLI. The CLI can be obtained either from the Dell website (under the Linux download section; you must have the driver compiled with the AAC_COMPAT_LINUX option), or from the Adaptec website under the download section for the 5400S RAID card.
