The failover alertdelay lets you delay the logging of a critical event if the multi-path drivertransfers virtual disks to the non-preferred controller. If the multi-path drivertransfers the virtual disks back to the preferred controller within the specifieddelay period, a critical event is not logged. If the transfer exceeds this delayperiod, then a virtual disk-not-on-preferred-path alert is issued as a criticalevent. You can also use this option to minimize multiple alerts when more thanone virtual disk fails over because of a system error, such as a failed host adapter.For more information, see the PowerVault Modular Disk Storage Manageronline help topics.
