Fabric Zoning And Lun Security; Connecting The Disk Array - HP StorageWorks P9000 Configuration Manual

Fabric zoning and LUN security

By using appropriate zoning and LUN security, you can connect various servers with various
operating systems to the same switch and fabric with the following restrictions:
Storage port zones can overlap if more than one operating system needs to share an array
port.
Heterogeneous operating systems can share an array port if you set the appropriate host
group and mode. All others must connect to a dedicated array port.
Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port.
LUN Manager provides LUN security by allowing you to restrict which LUNs each host can
access.
QLogic and Emulex FCAs must be in separate zones (a QLogic zone and an Emulex zone)
whether the FCAs are in the same or separate servers.
If booting over the SAN, within a server, the booting FCAs must be from the same vendor.
Additional data storage FCAs can be from a different vendor.

Environment
Standalone SAN
(non-clustered)
Clustered SAN
Multi-Cluster SAN
If you plan to use clustering, install and configure the clustering software on the servers.
Clustering is the organization of multiple servers into groups. Within a cluster, each server is
a node. Multiple clusters compose a multi-cluster environment. The following example shows
a multi-cluster environment with three clusters, each containing two nodes. The nodes share
access to the disk array.

Connecting the disk array

The HP service representative performs the following steps to connect the disk array to the host:
OS mix
homogeneous (a Not required
single OS type present
in the SAN)
heterogeneous (more Required
than one OS type
present in the SAN)
Fabric zoning LUN security
Must be used when
multiple hosts or cluster
nodes connect through
a shared port
