HP StorageWorks Disk Array XP operating system configuration guide: MPE/iX (A5951-96145, November, 2005)

When you are installing A6795A Fibre Channel HBAs o n A-Class and N-Class systems,

be sure to record the I/O slot paths where you install the cards. You will need the

I/O paths of these HBAs later during the I/O conﬁguration procedure. For SCSI HBA

installations, recording the I/O paths is not required. You can determine those I/O

later using the MAPPER/MAPPER2 facility .

Fabric zoning a

If you plan to us

e clustering, install and conﬁgu re the clustering software on the servers.

Clustering is

the organization of multiple servers into groups. Within a cluster, each

server is a nod

e. 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.

Withi

n the Storag e Area N et work (SAN), the clusters may be homo geneous (all the

same operating system) or they m ay be h eterogeneous (mixed o p erating systems). How

you conﬁgure LUN security and fabric zoning depends on the operating system mix and

the SAN conﬁguration.
