What is the best procedure for adding new (Symmetrix SRDF) disk volumes to a production Windows 2008 - Cluster Enabler 3.1 active/passive two site cluster.
Ideally with no or minimal downtime to the two cluster hosts and existing clusterted applications.
Use the "cluster" command line on the WIndows cluster nodes. Such as:
Add the disk to the cluster
C:\>cluster res "Disk Z:" /create /type:"Physical Disk" /group:"Available Storage"
C:\>cluster res "Disk Z:" /priv DiskPath="Z:"
Then you can modify the cluster group as per last post.
