Displaying failover alert

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.

1. In the AMW, on the menu bar, select Storage Array > Change > Failover Alert Delay.
   The Failover Alert Delay window is displayed.
2. In Failover alert delay, enter a value between 0 and 60 minutes.
3. Click OK.
4. If you have set a password for the selected storage array, the Enter Password dialog is displayed. Type the current password for the storage array.
