4. When the reboot process is complete, the SC1> prompt reappears.
5. Move the controller mode switch (CCM or SCSI/DKI) to ENABL.
6. Go to the MRC> prompt and enter restore standby to restore the standby Control
Computer to the in-service state.
C. Use this option when the console is not available.
Move the controller mode switch (CCM or SCSI/DKI) from ENABL to DIAG to DISAB, and
all the way up to ENABL again.
When the reboot process is complete, the SC1> prompt reappears.
D. This option is used to reboot the standby Control Computer from the MRC> prompt. Use
the init standby command.
Restoring the Standby Switch
The following procedure outlines the steps to restore a standby Switch module. The switchover
switch command is also used to switch over to the in-service standby Switch module.

PROCEDURE 3-23. Restoring the Standby Switch
Application: Nodes with redundant Switch modules.
1. Use the dstat switch command to check the slot number and status of the redundant Switch
module.
2. At the CC0> prompt, enter the restore switch command.
After the message Standby switch <module address> is downloading appears,
the CC0> prompt returns. The process runs in the background for about six minutes before
the following message appears.
<YY-MM-DD> <hh:mm:ss> NODE=<xxxxx>
8635B MODADDR=<addr> SWITCH=standby MODTYPE=switch
REPORT STATUS: swmaint: Restore standby switch successful.
3. Synchronize the database using the sync command.
4. If an error is detected on an active Switch module, automatic switchover to the in-service
standby Switch module occurs. Alarm messages indicate that a switchover has occurred.
Use the dstat switch command to determine the status of the standby Switch module.
