The Activate on Creation option is enabled by default. This causes the pool to be activated
as soon as it is created. If you choose not to activate the pool, you need to manually
activate it later before it can be used.
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 4b . If you want to cluster-enable the pool at a later date, see the OES 2 SP2:
Novell Cluster Services 1.8.5 for NetWare Administration Guide for more information.
4b Specify the Virtual Server Name , IP Address , Advertising Protocols and, if necessary, the
CIFS Server Name .
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 will be
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 hosting the pool.
You can select one or all of the advertising protocols. NCP™ is the protocol used by
Novell clients, CIFS is the protocol used by Microsoft clients, and AFP is the protocol
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.
5 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.
D.2 Creating NSS Volumes
After you create the pool and its mirror, you must create an NSS volume on each of the pool
resources so that it works properly as a cluster resource. To create an NSS volume on a shared pool,
follow the instructions in “
Creating NSS Volumes on a Shared Pool ” in the OES 2 SP1: Novell
Cluster Services 1.8.6 for Linux Administration Guide .
You must create at least one shared volume in a cluster-enabled pool. Typically, all volumes are
created when you initially set up the cluster resource and before you need to cluster migrate or fail
over the resource to other servers in the cluster.
