Multipath configuration
The server starts up with the same disk status (online or offline) as when the multipathing was set up re-
gardless of the SAN Policy setting.
• When the multipathing of an online disk is set up during the configuration of the environment
The multipath disk starts up in the online status after the firmware is updated.
When the multipathing of an offline disk is set up during the configuration of the environment
•
The multipath disk starts up in the offline status after the firmware is updated.
●
Method for proactively preventing occurrences
For multi-path configurations, there are no proactive measures (such as a setting change) to prevent the disk
from becoming offline after the environment is configured. In addition, the disk status when multipathing
was set up cannot be checked after the environment is configured.
Perform the procedure in
while the firmware is updated.

Measure to take after a problem occurs
When the OS can be started up
•
Manually change the offline disks to online by following the procedure below.
1
Click the [Start] button, select [Computer Management] under [Administrative Tools] and then select
[Manage Discs] (or [Disk Management]) in the left pane.
2
Select each offline disk, then right-click the selected disk to change the status to online.
• When the OS cannot be started up
If the Active Directory database is located in a disk other than the OS area, the OS may not be able to start
up because the disk is offline and the OS cannot access the Active Directory database.
In this case, the disk can be recovered by starting the OS in the Directory Services Restore Mode and chang-
ing the disk status to online.
The procedure for restoring (or reconfiguring) the disk is as follows:
1
Start the server.
2
Press the [F8] key on the server start-up screen.
3
The Advanced Boot Options screen appears.
4
Select Directory Services Restore Mode.
5
Log in as Administrator after the OS starts.
6
Select [Computer Management] under [Administrative Tools] and then select [Manage Discs] (or
[Disk Management]) in the left pane.
7
Select each offline disk, then right-click the selected disk to change the status to online.
