The Cluster Enable on Creation option is also enabled by default. If you want to cluster-enable
the pool at the same time it is created, accept the default entry ( Yes ) and continue with Step 6 . If
you want to cluster-enable the pool at a later date, change the default entry from Yes to No ,
select Create , and then go to “Creating NSS Volumes” on page 144 .
6 Specify the virtual server name, IP address, and advertising protocols.
When you cluster-enable a pool, a virtual Server object is automatically created and given the
name of the Cluster object plus the cluster-enabled pool. For example, if the cluster name is
cluster1
and the cluster-enabled pool name is
pool1
, then the default virtual server name is
cluster1_pool1_server
. You can edit the field to change the default virtual server name.
Each cluster-enabled NSS pool requires its own IP address. The IP address is used to provide
access and failover capability to the cluster-enabled pool (virtual server). The IP address you
assign to the pool remains assigned to the pool regardless of which server in the cluster is
accessing the pool.
The
NCP option is selected by default. NCP
TM
(NetWare Core Protocol
TM
) is used by NSS to
enforce the Novell trustee model of file access for all users of the data, and also as an
advertising protocol for NCP clients. Selecting
NCP causes commands to be added to the pool
resource load and unload scripts to activate the NCP protocol on the cluster.
IMPORTANT: Using the CIFS check box or the AFP check box requires that Novell CIFS for
Linux or Novell AFP for Linux is already installed and configured on the nodes in the cluster
and nodes in the peer clusters where you want to be able to fail over this pool cluster resource.
Select the CIFS check box to add it as an advertising protocol. Specify a CIFS share name for
users to access the resource. Selecting CIFS causes commands to be added to the pool resource
load and unload scripts to activate the Novell CIFS for Linux protocol on the cluster.
Select the
AFP check box to add it as an advertising protocol. Selecting AFP causes commands
to be added to the pool resource load and unload scripts to activate the Novell AFP for Linux
protocol on the cluster.

Select Create to create and cluster-enable the pool.
8 Repeat Step 3 to Step 7 for each additional pool you want to create on shared storage.
9
Select Partitions from the NSSMU main menu.
10 Select the partition you want to mirror (this is the partition that was created when you created
the pool), then press the F3 key.
11 Enter a name for the software RAID 1 device that will be created.
For more information on configuring software RAID for NSS, see “
Managing NSS Software
RAID Devices ” in the OES 2 SP2: NSS File System Administration Guide .
12 Select the shared device with free space that you want to use as the mirror, 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. You can select up to three shared devices.
13
Repeat Step 9 to Step 12 for each additional shared pool that you want to mirror.
14 Continue with “Creating NSS Volumes” on page 144 .
