3.1.4 Shared Disk System Requirements

A shared disk subsystem is required for each cluster in order to make data highly available. Make
sure your shared storage devices meet the following requirements:
"Shared Devices" on page 36
"SBD Partitions" on page 37
"Shared iSCSI Devices" on page 37
"Shared RAID Devices" on page 37
Shared Devices
Novell Cluster Services supports the following shared disks:
Fibre Channel LUN (logical unit number) devices in a storage array
iSCSI LUN devices
SCSI disks (shared external drive arrays)
Before installing Novell Cluster Services, the shared disk system must be properly set up and
functional according to the manufacturer's instructions.
Prior to installation, verify that all the drives in your shared disk system are recognized by Linux by
viewing a list of the devices on each server that you intend to add to your cluster. If any of the drives
in the shared disk system do not show up in the list, consult the OES 2 documentation or the shared
disk system documentation for troubleshooting information.
Devices where you plan to create shared file systems (such as NSS pools and Linux POSIX file
systems) must be unpartitioned devices that can be managed by EVMS. NSS automatically
partitions the device and lays down a Cluster Segment Manager on the partition when you use NSS
tools to create a pool. You use the EVMS GUI to partition and create shared Linux POSIX file
systems.
