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 logicaldrive
where:
v controller is the ServeRAID controller number (1–12)
v logicaldrive 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 Predictive Failure Analysis
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 (1–4)
v sid is the SCSI ID for the device (0–15)
Use the eraseevent function to clear all logged entries in the
designated event log. See getevent help for information about the
contents of the device event log and the controller soft and hard
event logs.
Supported operating systems: Windows NT, Windows 2000, OS/2,
NetWare, Linux, OpenServer, UnixWare, and DOS
Command: ipssend eraseevent controller options
where:
v controller is the ServeRAID controller number (1–12)
v options is the designated event log:
– DEVICE for the device event log
– SOFT for the ServeRAID controller soft event log
