Use the rebuild function to rebuild a designated disk drive. This
function is valid for disk arrays that contain one or more logical
drives that are in the critical state. Progress is indicated during the
rebuild operation, but you can also use the getstatus function to
obtain progress information about the rebuild.
Supported operating systems: Windows NT, Windows 2000
Command: ipssend rebuild controller dch dsid nch nsid
where:
v controller is the ServeRAID controller number (1–12)
v dch is the channel number for the defunct drive (1–4)
v dsid is the SCSI ID for the defunct drive (0–15)
v nch is the channel number for the new drive (1–4)
v nsid is the SCSI ID for the new drive (0–15)
Use the setstate function to change the state of a physical device
from its current state to a new state.
Attention:
For example, you might lose data if you reset a defunct device to
online without first performing a rebuild operation.
Supported operating systems: Windows NT, Windows 2000
Command: ipssend setstate controller channel sid nstate
where:
v controller is the ServeRAID controller number (1–12)
v channel is the channel number for the drive (1–4)
v sid is the SCSI ID for the drive (0–15)
v nstate is the new state for the drive. Valid states are:
– EMP for Empty
– RDY for Ready
– HSP for Hot spare
– SHS for Standby hot spare
– DDD for Defunct disk drive
– DHS for Defunct hot spare
– RBL for Rebuild
– SBY for Standby
– ONL for Online.
Use the unblock function to gain access to a blocked logical drive.
RAID level-0 logical drives become blocked if they are in an array
that contains RAID level-1 or level-5 logical drives and the array is
being rebuilt. Because the RAID level-0 logical drives cannot be
rebuilt, the data stored on the RAID level-0 logical drives is
damaged and should not be accessed. After you issue the unblock
function, you must re-create or restore the data previously stored
on the RAID level-0 logical drives.
Supported operating systems: Windows NT, Windows 2000
Command: ipssend unblock controller drivenum
