3.3 Troubleshooting The following sections provide some suggestions for troubleshooting. 3.3.1 RAID Properties Menu Item Disabled Problem: The RAID Properties menu item is disabled Solution: Check the following: • Is the adapter in the boot adapter list? • Does the LSI adapter have Integrated Mirroring (IM) firmware? • Is an IM volume already created on each Fusion-MPT adapter in the system? • Is "Disable Integrated RAID" set to Yes in the Global Properties screen? • Are there at least two disks on the selected SCSI bus? 3.3.2 IM Volume Uses Extra SCSI ID Problem: The IM volume with two mirrored disks uses an extra SCSI ID off the bus (that is, none of the physical disks of the IM volume has the same SCSI ID as the IM volume), and the configuration utility won't allow the disk at the ID currently defined as the volume ID to be configured. Solution: To change the IM volume configuration so it does not use an extra SCSI ID but also keeps the same volume ID, do the following: 1. Go to the RAID Properties screen. Note which SCSI ID the primary disk is using and which SCSI ID the volume is using. Also note the SCSI IDs of the remaining disks of the IM volume. 2. Set the IM volume disks to "No" and save the configuration (in other words, break the volume). 3. Return to the RAID Properties screen and reconfigure the IM volume as follows: - Primary disk at same ID as before - Secondary disk at ID used previously by the volume - Hot spare at SCSI ID used previously by the secondary disk 3-14 Setting Up Integrated Mirroring Version 1.0 Copyright © 2003 by LSI Logic Corporation.

3.3
Troubleshooting
The following sections provide some suggestions for troubleshooting.
3.3.1
RAID Properties Menu Item Disabled
Problem:
The RAID Properties menu item is disabled
Solution:
Check the following:
•
Is the adapter in the boot adapter list?
•
Does the LSI adapter have Integrated Mirroring (IM) firmware?
•
Is an IM volume already created on each Fusion-MPT adapter in the
system?
•
Is “Disable Integrated RAID” set to
Yes
in the Global Properties
screen?
•
Are there at least two disks on the selected SCSI bus?
3.3.2
IM Volume Uses Extra SCSI ID
Problem:
The IM volume with two mirrored disks uses an extra SCSI ID
off the bus (that is, none of the physical disks of the IM volume has the
same SCSI ID as the IM volume), and the configuration utility won't allow
the disk at the ID currently defined as the volume ID to be configured.
Solution:
To change the IM volume configuration so it does not use an
extra SCSI ID but also keeps the same volume ID, do the following:
1.
Go to the RAID Properties screen. Note which SCSI ID the primary
disk is using and which SCSI ID the volume is using. Also note the
SCSI IDs of the remaining disks of the IM volume.
2.
Set the IM volume disks to "No" and save the configuration (in other
words, break the volume).
3.
Return to the RAID Properties screen and reconfigure the IM volume
as follows:
–
Primary disk at same ID as before
–
Secondary disk at ID used previously by the volume
–
Hot spare at SCSI ID used previously by the secondary disk
