Creating and Mirroring NSS Pools on Shared Storage
NSS creates a partition for you when you create a pool.
Prior to creating and mirroring NSS pools on shared storage, ensure that you have the following:

All servers in the cluster connected to a shared storage system

One or more drive arrays configured on the shared storage system

The drives on the shared storage system marked as shared.
To create and mirror NSS pools:
1 Start NSSMU by entering
2 Select Devices from the NSSMU main menu and mark all shared devices as sharable for
clustering.
On Linux, shared disks are not by default marked sharable for clustering. With a device marked
as sharable for clustering, all partitions on that device are automatically sharable.
You can press F6 to individually mark devices as sharable.
3 ???From the NSSMU main menu, select Pools, press the Insert key, and then type a name for
the new pool you want to create.
4 Select the device on your shared storage where you want the pool created.
Device names might be labelled something like
5 Choose whether you want the pool to be activated and cluster-enabled when it is created.
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
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
6 Specify the virtual server name, IP address, and advertising protocols.
NOTE: The CIFS and AFP check boxes can be selected, but CIFS and AFP functionality does
not apply to Linux. Selecting the check boxes has no effect.
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
and the cluster-enabled pool name is
cluster1
cluster1_pool1_server
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.
