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. For more information, see the online help topics.
To configure a failover alert delay:
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.
Changing The Cache Settings On The Storage Array
To change the storage array cache settings:
1. In the AMW, select Storage Array → Change → Cache Settings.
The Change Cache Settings window is displayed.
2. In Start flushing, select or enter the percentage of unwritten data in the cache to trigger a cache flush .
3. In Stop flushing, select or enter the percentage of unwritten data in the cache to stop a cache flush in progress.
4. Select the appropriate Cache block size.
A smaller cache size is a good choice for file-system use or database-application use. A larger cache size is a good
choice for applications that generate sequential I/O, such as multimedia.
