Release Notes

Dell™ PowerEdge™ Cluster

SE600Wi Systems Important

Information

In a redundant direct-attached or network-attached configuration, the logical

unit numbers (LUNs) on a Dell PowerVault™ MD3000i storage array may be

trespassed (the ownership of the LUN is moved to a different storage controller)

when a cluster node reboots. When the LUNs on the PowerVault MD3000i

storage array are trespassed:

• The Microsoft

Windows

System Event Log (SEL) logs the event

number 801 and event number 10 from

md3dsm

• The Dell Modular Disk Storage Manager flags the storage array as

Not Optimal

and displays the following message in the Recovery Guru:

Virtual Disk Not On Preferred Path..

Use the Recovery Guru in the Modular Disk Storage Manager to rebalance

the LUNs and reassign them back to the original storage controllers. To access

the Recovery Guru, go to Modular Disk Storage Manager→ Summary→

Storage Array Needs Attention.

You can also manually rebalance the LUNs using a CLI command or go to

Modular Disk Storage Manager→ Support→ Manage RAID Controller

Modules→ Redistribute Virtual Disks.

A fix for this issue will be available in a future firmware release.
