D.1 Creating and Mirroring NSS Partitions on
Shared Storage
NSS provides a software RAID 1 configuration option that mirrors NSS pool partitions. The
partitions are automatically created by the NSS management tools when you create a pool and when
you mirror the pool. NSS supports two to four segments in a software RAID 1. To ensure disaster
recovery, the device you select to mirror should be in another storage array in the other data center.
For example, you create the original pool in one cluster, then create mirrors for that pool in the other
peer clusters, for a total two to four segments.
NSS partitions must be mirrored after they are created. If you have an existing partition that you
want to mirror, you can either create another partition of equal size on another device to mirror the
first partition to, or let the mirroring software automatically create another partition of equal size on
another device.
Prior to creating and mirroring NSS partitions 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.
NSS is installed and running. For information, see
Services" in the
You can add CIFS or AFP as advertising protocols for the NSS pool resource when you create
the resource, or add them later by using the Clusters plug-in for iManager.
You need a static IP address for the pool resource. It must be in the same subnet as the cluster
master IP address.
To create and mirror NSS pools:
1 Start NSSMU by entering
2 Select Partitions from the NSSMU main menu.
3 Press the Insert key and select the device on your shared storage system where you want to
create a partition.
With a device marked as sharable for clustering, all partitions on that device are automatically
sharable.
Device names are not changeable and might be labeled something like 0x2 or 0x1.
4 Select NSS as the partition type, then specify the partition size and, if desired, an NSS pool
name and label.
If you specify a pool name, a pool by that name is automatically created on the partition. If no
pool name is specified, you need to create a pool on the partition later.
4a If you chose to create a pool, choose whether you want the pool to be activated and
cluster-enabled when it is created.
