ExtremeWare XOS 11.5 Command Reference Guide
369
run msm-failover
run msm-failover {force}
Description
Causes a user-specified node failover.
Syntax Description
Default
N/A.
Usage Guidelines
Use this command to cause the primary MSM to failover to the backup MSM.
Before you initiate failover, use the
show switch {detail}
command to confirm that the nodes are in
sync and have identical software and switch configurations. If the output shows MASTER and
BACKUP (InSync), the two MSMs are in sync.
If the MSMs are not in sync, and both MSMs are running ExtremeWare XOS 11.0 or later, use the
synchronize
command to get the two MSMs in sync. This command ensures that the backup has the
same software in flash as the master.
NOTE
Both the backup and the master MSMs must be running ExtremeWare XOS 11.0 or later to use the
synchronize
command.
If the MSMs are not in sync, and one MSM is running ExtremeWare XOS 10.1 or earlier, specify the
force
option of the
run msm-failover
command. By specifying
force
, failover occurs regardless of
the version of software running on the MSMs.
Example
The following command causes a user-specified MSM failover:
run msm-failover
History
This command was first available in ExtremeWare XOS 10.1.
