11.1 Requirements for Shared Linux POSIX
Volumes
EVMS must be installed and running on each server in the cluster.
You must install Novell Cluster Services before you create shared disk partitions on shared
storage (storage area network, or SAN).
Cluster Segment Manager (CSM) containers require Novell Cluster Services to be running on
all nodes that access the CSM container. Do not create or make to modifications to EVMS
objects unless Novell Cluster Services is running.
You should carefully plan how you want to configure your shared storage prior to installing
Novell Cluster Services. For planning information, see the following:
Section 3.1.4, "Shared Disk System Requirements," on page 36
Section 3.1.5, "SAN Rules for LUN Masking," on page 38
Each cluster-enabled Linux volume needs its own static IP address. The IP address is used to
provide access and failover capability to the cluster-enabled volume. The IP address assigned
to the volume remains assigned to it regardless of which server in the cluster is accessing the
volume.
In a mixed cluster of NetWare
cluster resources cannot be created until the entire cluster is migrated to OES 2 Linux. Linux
POSIX file systems as cluster resources cannot be migrated or failed over to NetWare cluster
nodes. Only NSS pool cluster resources that are created on a NetWare cluster node can be
failed over between Linux and NetWare nodes of a mixed-node cluster.
