                     Smart Array backplane RAID controllers using parallel
                     SCSI expect to be connected to enclosures that have
                     individual built in enclosure processors. This
                     processor or Environmental Monitoring Unit (EMU)
                     monitors fans, controls LEDs and so on. The EMU also
                     provides information about hot-plug events available
                     in the enclosure. The Smart Array controller is thus
                     always aware of the insertion or removal of a SCSI
                     disk drive when used with such type of enclosures,
                     like MSA30.

                     The 64xx series Smart Array card can also be cabled 
                     to the internal parallel SCSI drives on applicable I64
                     platforms. These drives are housed in an enclosure
                     that is totally passive with respect to hot-plug event
                     notification. The Smart Array controller cannot
                     detect that a physical disk has been hot-inserted.
                     If a RAID physical disk fails and must be replaced,
                     the controller will not start the recovery process
                     on the affected RAID volumes.
                       
                     After replacing the bad disk(s) with the new disk(s),
                     if the system is rebooted before issuing the SCAN ALL
                     command, then all the affected RAID volumes configured
                     on these disks will move to the "VOLUME ready for
                     recovery operation" state. The REBUILD operation will
                     not start automatically.
   
                     The "START RECOVER" command will initiate the REBUILD
                     operation for all the UNITs configured in the
                     disk group sequentially.

                     Note that "hiding" the insertion of a new disk from the
                     controller can result in the REBUILD operation not
                     starting automatically, even if the controller can detect
                     hot-plug events, such as when connected to a MSA30. 
                     Removing a disk while the host system is running, and
                     replacing the disk while the host system is powered off,
                     will effectively hide the insertion. The START RECOVER
                     command will initiate the REBUILD operation in such
                     scenarios also. 

                     This command is supported on both OpenVMS Alpha and
                     OpenVMS I64 platforms.

                     Note: Refer to SCAN ALL command for additional
                           information on rebuild of volumes.
