Recovering Drives Configured for
NetWare Fault Tolerance
If you have chosen no fault tolerance for the drives connected to your
Smart Array 3200 Controller and have configured NetWare mirroring or
NetWare controller duplexing, perform the following steps to recover the data
after a drive failure:
1. Identify the failed physical drive that caused the NetWare device to be
deactivated. Record the device number and device name of the failed
logical drive. For example:
NWPA [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT
Failure messages are recorded on the server console and also in the
server error log file that can be viewed using the SYSCON utility (3.12)
or the NWADMIN utility (4.x). You will use this information later to
create a valid partition.
2. Load the INSTALL.NLM and select the Disk Options Mirroring menu. Select
the mirrored logical partition that was affected by the drive failure (see Step
1). Record the device number and partition number of the operational logical
drive in this mirrored group. This information will be used later to remirror
the repaired logical drive. For example:
NWPA: [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT
3. Delete the unavailable (possibly out of sync) device from the Mirror
Partition group. This device is unavailable due to the drive failure.
4. Record the drive bay location of the failed physical drive. The new
physical drive must be inserted into this drive bay.
5. If the failed drive is hot-pluggable, Skip to step 6. Otherwise, schedule
server down time, take the server offline, and power-off the unit.
