rpr - repair parity information in an HP SCSI disk array LUN
rpr -b block device_file
rpr repairs the data parity information on a LUN in an HP SCSI disk
array when the LUN is configured in a data redundant RAID-level (RAID
_1, RAID_3, or RAID_5). block is the logical address of the data
block corresponding to the parity block needing repair. block is
specified using the -b parameter. device_file is the name of the
device file for the LUN.
Use scn (see scn(1M)) to identify data blocks that do not have correct
rpr returns the following values:
0 Successful completion.
-1 Command failed (an error occurred).
DIAGNOSTICS AND ERRORS
Errors can originate from problems with:
+ SCSI (device level) communications
+ system calls
Error messages generated by rpr:
usage: rpr -b block>>>> <<<<special>>>>
rpr encountered an error in command syntax. Re-enter the command
with all required arguments, in the order shown.
rpr: LUN does not exist
The addressed LUN is not configured, and is not known to the
rpr: LUN # too big
The LUN number, derived from the device file name, is out of
rpr: Not a raw file
rpr must be able to open the device file for raw access.
rpr: Transfer length error
The amount of data actually sent to or received from the device
was not the expected amount.

rpr: Not an HP SCSI disk array
The device being addressed is not an HP SCSI disk array.
SCSI (device level) communication errors:
Sense data associated with the failed operation is printed.
Error messages generated by system calls:
rpr uses the following system calls:
malloc(), free(), stat(), open(), close(), fopen(), fclose(),
read(), write(), unlink(), and ioctl().
Documentation for these HP-UX system calls contains information about
the specific error conditions associated with each call. rpr does not
alter the value of errno. The interpretation of errno for printing
purposes is performed by the system utility strerror().
To repair block 12345 of the LUN /dev/rdsk/c2t6d0 on a series 800:
rpr -b 12345 /dev/rdsk/c2t6d0
The HP C2425 and HP C2427 disk arrays are only supported on Series 700
systems running HP-UX version 9.0X.
The HP C2430 disk array is supported on Series 700 and 800 systems
running HP-UX versions 9.0X and 10.0X.
rpr was developed by HP.
