Scheduling revert on Active slave
A revert can scheduled only on the active slave or passive to active slave state.
Before scheduling a revert, a non-revertive must be enabled.
Revert can be scheduled using the following command,
nplus1 revert schedule <month/day/year> <hh:mm:ss>
For Example:
nplus1 revert schedule 12/01/2012 01:02:03
Master1(15)# sh nplus1
-------------------------------------------------
Current State : Active Slave
Non-Revertive Mode : Enable

Master IP : 10.1.1.10
Master Hostname : MasterNplus1
Slave IP : 10.1.1.21

At this time, the active slave switches the role to standby master and reverts to the
passive state.
Cancel the Schedule Revert
To Cancel the Schedule Revert the following command is used:
nplus1 revert cancel
Reverting the Active Slave to Standby
You may want to change the role the active slave back to standby slave if it becomes
obvious that the failed controller will be offline for some time. By reverting the slave
from active to standby, the cluster can continue to be monitored.
Use the nplus1 revert command to change the status of the slave from active to
standby.
