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" on page 112 "Using EVMSGUI to Create a Mirrored Cluster SBD Partition" on page 113 Using SBDUTIL to Create a Mirrored Cluster SBD Partition 1 As the root user, enter the following at the terminal console of a Linux cluster server: 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.
