Problem-isolation and debug functions

The IPSSEND problem-isolation and debug functions include the following:
certify
eraseevent
Attention: You must be very careful when you use this function.
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, OS/2,
NetWare, Linux, OpenServer, UnixWare, and DOS
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, OS/2,
NetWare, Linux, OpenServer, UnixWare, and DOS
Command: ipssend unblock controller drivenum
where:
v controller is the ServeRAID controller number (1–12)
v drivenum is the logical drive number (1–8)
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:
v controller is the ServeRAID controller number (1–12)
v channel is the channel number for the device (1, 2, 3, or 4)
v sid is the SCSI ID for the device (0–15)
Use the eraseevent function to clear all logged entries in the
