Adding CLustered Disk Resource

[Ken Krause]

I have an existing active/passive cluster with a shared
SAN device. The existing shared disk resource is filling
up and I have added a second array/logical drive. The
problem is that when I go to add the new physical disk
resource, no drives appear in the Disk Parameters tab.
Both nodes see the drive and partitions in disk manager
and they both use the same drive letters for the
partitions. I ceated the logical drive using the array
config utility and wrote the disk signature from the
active node.
Any ideas?

TIA
Ken

Is the HDD configured as a shared LUN on the SAN ? it
will need to be.

You may have to reconfigure your Physical resource
completely so that it sees both of you logical drives.
Try redoing the cluster set-up see if that helps

This happens if you add the disk to the cluster incorrectly. For some
reason, if your partition is created on a new device while cluster disk is
enabled, it will not recognize your newly added disk. In order to correct
this, you'll need to disable the "Cluster Disk" driver on both cluster nodes
and then re-create your partition. You can read about this in the following

Try running "cluadmin ."
Then create the disk resouce.
