Workaround for Windows restart
In the PRIMEQUEST 2000 series, the restart request can be suppressed by identifying the Reserved SB in
advance.
Execute the following procedures for all the partitions with Windows installed.
When these workaround steps are executed, restart is not requested when there is a switching to the
Reserved SB due to SB failure.
1. Shutdown the partition after completing the installation of Windows.
2. Remove one SB from the partition by using the MMB Web-UI. When there are multiple SBs, any SB can
be removed.
For details, see ‘Removal of SB and IOU’ of’ 3.4.1 Partition Configuration Setting’ in “PRIMEQUEST 2000
series Installation Manual” (C122-E174).
3. Add the SB of the Reserved SB to the partition.
For details, see ‘Adding an SB/IOU’ of 3.4.1 Partition Configuration Setting’ in “PRIMEQUEST 2000
series Installation Manual” (C122-E174).
4. Power on the partition and start the Windows.
5. Log in with Administrator privilege. After the message that the system must be restarted is displayed on
the window, follow the instructions and restart the system.
6. Shutdown the system after restarting the Windows has been completed.
7. Using the MMB Web-UI, remove the SB of the Reserved SB, which was added in Step 3.
8. Add the SB removed in Step 2, to the partition.
Notes on VMware
When there is a switching to the Reserved SB in the partition running VMware, the guest operating system
may not start at the first restart after the switch over.
Set the guest operating system to automatically restart, and the Blue Window Timeout items when setting
Reserved SB in a partition running VMware.
For details on the setting, see the VMware Manual.
Switching rules
Switching rules for the Reserved SB are as follows.
- Determining the switching source SB
- When an SB has been configured as a Reserved SB for multiple partitions, and there is simultaneous
failure in multiple partitions, the partition with the lowest number takes priority for switching (Example 1).
- When multiple SBs fail in a partition, the SB with the lowest number takes priority for switching (Example
2). Determining the switching destination SB
- When multiple Reserved SBs have been sent in a partition, and there are Reserved SBs that do not
belong to any partition, the Reserved SB having the highest SB number takes priority for switching
(Example 3).
- When multiple Reserved SBs are set in a partition, and there are only Reserved SBs included in the
partition, the Reserved SB having the highest SB number in a powered off partition takes priority for
switching (Example 4). If all the partitions are powered on, the Reserved SB with the highest SB number
takes priority for switching (Example 5).
