used by Macintosh* clients. Selecting any of the protocols causes lines to be added to the
pool resource load and unload scripts to activate the selected protocols on the cluster. This
lets you ensure that the cluster-enabled pool you just created is highly available to all your
clients.
If you select CIFS as one of the protocols, a CIFS Server Name is also required. This is the
server name CIFS clients see when they browse the network. A default server name is
listed, but you can change the server name by editing the text in the field.
4c Select Create to create and cluster-enable the pool.

Select the partition you want to mirror (this might be the partition you just created) and press
the F3 key.
6 Select the device with free space or the partition you want to mirror to, then select YES to
mirror the partition.
To ensure disaster recovery, the device you select to mirror should be in another storage array
in the other data center.
Creating an NSS Pool and Volumes
After an NSS partition has been created and mirrored, if you have not already done so, you must
create an NSS pool and volume on that partition. To do this, follow the instructions in "“
Creating
NSS Pools ” " in the “ Installation and Setup ” section of the Novell Cluster Services 1.8.2
Administration Guide for NetWare .
Novell Cluster Services Configuration and Setup
After configuring NSS mirroring and creating a pool and volume on the mirrored NSS partition, if
you did not cluster-enable the NSS pool on the mirrored partition when you created it, do so by
following the instructions in the “
Installation and Setup ”section of the Novell Cluster Services 1.8.2
Administration Guide for NetWare .
When you cluster-enable a shared disk pool, the commands to start and stop the pool resource are
automatically added to the resource load and unload scripts.
Checking NSS Volume Mirror Status
After you have configured NSS mirroring with Novell Cluster Services, you should check to ensure
that it is working properly in a cluster environment.
1 Ensure that the volumes on the cluster-enabled pool are mounted on the assigned server by
entering
volumes
at the server console.
2 Check the mirror status of the mirrored partition by entering
mirror status
at the server
console of the server where the NSS pool on the mirrored partition is active.
After entering mirror status, you should see a message indicating that mirror status is 100
percent or a message indicating that the mirrored object is fully synchronized.
3 Migrate the pool to another server in the cluster and again check to ensure the volumes on the
pool are mounted by entering
volumes
at the server console.
4 Check the mirror status of the partition again by entering
mirror status
at the server
console.
