Following SCSI ID’s have the same data <v.z>
Channel-x:a.b.c
Problem: The physical disk roaming feature found the same data on two or more
physical drives on channel (x) with the listed SCSI IDs (a, b, c, and so on). The
adapter cannot determine which drive with duplicate information to use.
Suggested solution: Remove the drive or drives that should not be used.
Other Troubleshooting
NOS Does Not Load (Boot)
Problem: Operating system does not load at start-up time.
Suggested solutions:
• Use the Setup utility to define the boot order. (Press the F2 function key
during startup.)
• Use HP NetRAID Express Tools to enable/disable the HP NetRAID BIOS
as required.
Hard Drive Fails Often
Problem: One of the hard drives in the array fails often.
Suggested solutions:
• Check the drive error counts using HP NetRAID Assistant Physical Drive
Properties. Be aware that the drive error counter clears if the drive is
moved or powered off while the adapter remains powered on.
• Format the drive.
• Rebuild the drive.
• If the drive continues to fail, replace the drive with another drive with the
same capacity, and rebuild.
