8.16.4 Creating a Mirrored Cluster SBD Partition

If the cluster has a shared disk system, you can achieve a greater level of fault tolerance for the SBD

partition by mirroring it. Novell Cluster Services uses the NSS software RAID capability to mirror

the SBD partition.

You can mirror the SBD partition when you install Novell Cluster Services on the first node, or you

can create it afterwards by using the sbdutil utility or the evmsgui utility to create a mirrored cluster

partition.

Using SBDUTIL to Create a Mirrored Cluster SBD Partition

1 As the

sbdutil -c -n clustername -d device_name -d device_name

Replace device_name with the name of the devices where you want to create the cluster

partition and its mirror. Use the EVMSGUI (or EVMSN or EVMS) tool to check the names of

the devices if needed, and only use the base (leaf) names (such as sdb or mpathd) with the -d

option.

For example, you might enter something similar to the following:

sbdutil -c -n mycluster1 -d sdb -d sdc

2 Modify the Cluster object in eDirectory to enable its NCS: Shared Disk Flag attribute.

2a In a Web browser, open iManager, then log in to the Novell eDirectory tree that contains

the cluster you want to manage.

IMPORTANT: Log in as an administrator user who has sufficient rights in eDirectory to

delete and modify eDirectory objects.
