Failover Alert Display

You can change the failover alert delay for a storage array. The failover alert
delay lets you delay the logging of a critical event if the multi-path driver
transfers virtual disks to the non-preferred controller. If the multi-path driver
transfers the virtual disks back to the preferred controller within the specified
delay period, a critical event is not logged. If the transfer exceeds this delay
period, then a virtual disk-not-on-preferred-path alert is issued as a critical
event. You can also use this option to minimize multiple alerts when more
than one virtual disk fails over because of a system error, such as a failed host
adapter.

online help topics.
