Preparing Your Systems for Clustering
Access Logix is enabled by configuring the Access Logix option on your
storage system.
The storage systems are managed through a
management station
—a local or
remote system that communicates with Navisphere Manager and connects to
the storage system through an IP address. Using Navisphere Manager, you can
secure your storage data by partitioning your storage system arrays into LUNs,
assign the LUNs to one or more storage groups, and then restrict access to the
LUNs by assigning the storage groups to the appropriate host systems.
Access Logix is required if:
•
The server modules are configured in dissimilar configurations. These
configurations include:
–
Two or more stand-alone systems/non-clustered hosts.
–
Two or more clusters.
–
Any combination of server modules configured as cluster nodes and
stand-alone systems/non-clustered hosts.
•
MirrorView, SnapView, or SAN Copy are installed on your attached storage
system(s) and running in the cluster configuration.
Table 3-2 provides a list of cluster and host system configurations and their
Access Logix requirement.
