44 Preparing Your Systems for Clustering
Assigning the Virtual Disks to Cluster Nodes
NOTE: For best practice, have at least one virtual disk for each application. If
multiple NTFS partitions are created on a single LUN or virtual disk, these partitions
will not be able to fail over individually from node-to-node.
To perform data I/O to the virtual disks, assign the virtual disks to a cluster
node by performing the following steps:
1
Open a Web browser.
2
Type the storage system IP address in the
Address field
.
The
Navisphere Express
console is displayed.
3
Login with user name and password that were created during the storage
initialization.
4
In the
Manage
menu,
a
Click
Disk Pools
. You can create multiple disk pools.
b
Click
Virtual Disks
. You can create multiple virtual disks for each disk
pool.
c
In the
Virtual Disks
screen, select the virtual disks that you want to
assign to the cluster node and click
Assign Server
.
5
In
Assign Server
screen, select the cluster nodes that you want to assign to
the virtual disk and click
Apply
.
6
Repeat step 4 and step 5 for each virtual disk.
7
Close the
Navisphere Express
window.
8
Verify that the PowerPath on the cluster nodes can access all paths to the
virtual disks.
