IBM 81Y Computer Hardware User Manual


 
136 Hardware Maintenance Manual: xSeries 250
where:
controller is the ServeRAID controller number (1–12)
dch is the channel number for the defunct drive (1–3)
dsid is the SCSI ID for the defunct drive (0–15)
nch is the channel number for the new drive (1–3)
nsid is the SCSI ID for the new drive (0–15)
setstate Use the setstate function to change the state of a physical device from its
current state to a new state.
Attention:
You must be very careful when you use this command. 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, OS/2, NetWare, Linux,
OpenServer, UnixWare, and DOS
Command:
ipssend setstate controller channel sid nstate
where:
controller is the ServeRAID controller number (1–12)
channel is the channel number for the drive (1–3)
sid is the SCSI ID for the drive (0–15)
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, and ONL for Online.
unblock 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 command, you must re-create or restore the data previously
stored on the RAID level-0 logical drives.
Supported operating systems: Windows NT, OS/2, NetWare, Linux,
OpenServer, UnixWare, and DOS
Command:
ipssend unblock controller drivenum
where:
controller is the ServeRAID controller number (1–12)
drivenum is the logical drive number (1–8)
Problem-isolation and debug commands
The IPSSEND problem-isolation and debug commands include the following:
certify Use the certify function to verify the media of a physical drive. When the
program finds a media error, it reassigns the sectors. A summary of
reassignments and PFA errors appears upon completion of the verification.
Supported operating system: DOS
Command:
ipssend certify controller channel sid
where:
controller is the ServeRAID controller number (1–12)
