10. SOFTWARE RAID1
10-18
10.4.4 When a problem occurs during recovery work
(1) Rebuilding does not start
The following are considered as a possible cause of this problem.
• The software RAID does not detect connection of HDD.
• Setting for manual rebuilding start is made.
• A used HDD is mounted as an HDD for replacement.
1. On the hardware status display window, confirm that the status of the mounted HDD is
shown as “OFFLINE”. If a replacement HDD is mounted before the message “Not
Connected” appears, remove the HDD and confirm that “Not mounted” appears. Then,
mount the replacement HDD again.
2. Enter the following command from the command prompt as administrator, and check the
setting to see if manual rebuilding is able to start.
C:¥> raidctrl /MANUAL
When “Manual Rebuild:ON” appears, enter the following command to start rebuilding.
C:¥> raidctrl /REBUILD
3. Check whether the event log (event ID: 3001, source: HTsfRaid_SYS) of the software
RAID is recorded referring to the “system” category of the event log. When the event log is
recorded, take the following actions according to error codes shown in the description of
the event log.
• Error code = 0x0504310* (*: an arbitrary value)
An HDD that was used as a software RAID may have been mounted. Check whether a
defective HDD is mounted. If an HDD that was used as a backup HDD is mounted,
replace the backup HDD with a new one, and then restart the recovery work in the same
way as “10.4.6 Recovery a normal HDD that has been set to offline by mistake”.
• Error code = other than 0x0504310* (*: an arbitrary value)
Access to the mounted HDD may have failed. Check the status of the HDD.
(2) A blue screen (0x9502) occurred during OS startup after HDD has been replaced
The HDD may have been used as a RAID1 array for another computer. Use a brand new
HDD or a new HDD.
