You are using a
PowerVault MD3000
or PowerVault
MD3000i storage
array and Virtual
Disks failover
continuously between
the two storage
controllers when a
storage path fails. The failback mode for
the cluster node(s) is
not set properly. Set the correct failback mode on each
cluster node:
• For PowerVault™ MD3000 storage,
merge the Cluster.reg file located
in the \utility directory of the Dell
PowerVault MD3000 Resource
Media into the registry of each
node. This file changes the
PowerVault MD3000 from
Stand
Alone to Cluster mode.
• For PowerVault™ MD3000i, merge
the Cluster.reg file located in the
windows\utility directory of the
Dell PowerVault MD3000i resource
media into the registry of each
node. This file changes the
PowerVault MD3000i from
Stand
Alone to Cluster mode.
You are using a
PowerVault MD3000
or PowerVault
MD3000i storage
array and Virtual Disk
Copy operation fails. The Virtual Disk Copy
operation uses the
cluster disk as the
source disk. To perform a Virtual Disk Copy
operation on the cluster share disk,
create a snapshot of the disk, and
then perform a Virtual Disk Copy of
the snapshot virtual disk.
