Failover operation

This topic provides information about failover operation.

When a failover monitor detects a triggering event, IFM invokes a failover operation and performs the following actions:

Removes existing deployment data from the standby server.
Powers off the standby server, if it is powered on, unless Ignore Power is enabled on the Deployments panel.
Attempts to copy the deployment data to the standby server.
If IFM is unable to copy the deployment data, IFM backs out the changes to the backup server and selects the next server from the standby pool and retries.
Once the deployment data is successfully copied to the backup server, IFM attempts to copy VLAN data, if specified by the settings in the failover monitor.

Notes:

To avoid a loss of data during a failover event, set up the standby pools to match the monitored pools.
(IBM BladeCenter devices only) For failover to occur to a standby server, the standby server must be powered off, unless Ignore Power is enabled on the Deployments panel.
(IBM Flex System devices only) You must provide the SNMV3 receiver IP address and the SNMV3 receiver password for the chassis. To define the values, select Edit on the Hardware Devices panel.
