The Tru64 UNIX Version 5.1A operating system is installed on
member system 1. It can be installed on an internal disk, as is the
case in Figure 11–1, or on a shared disk.
Member system 1 is used to create the cluster with the
clu_create
command.
Member system 2 is added to the cluster with the clu_add_member
command.
The shared storage for member systems 1 and 2 contains the root (/),
/usr, /var file systems for the cluster, and the boot disks for member
systems 1 and 2. (See the Tru64 UNIX
Installation Guide and the
TruCluster Server Cluster Installation manual for information about
installing the Tru64 UNIX and TruCluster Server software.)
Give member systems 1 and 2 one vote.
– Member systems 2, 3, 4, and 5 share storage on the second shared
SCSI bus. Four systems is the maximum number of cluster members
that may be on a shared SCSI bus.
The shared storage on this bus contains the member system boot
disks for member systems 3, 4, and 5.
Use member system 1 or 2 to add member systems 3, 4, and 5 to
the cluster.
Give member system 3 one vote.
– Member Systems 1, 6, 7, and 8 form the third shared SCSI bus.
The shared storage on this bus contains the member system boot
disks for member systems 6, 7, and 8.
Use member system 1 or 2 to add member systems 6, 7, and 8 to
the cluster.
Section 11.2.1 and Figure 11–2 provide the details about cabling member
systems 1 and 2 for the first shared SCSI bus.
Section 11.2.2 and Figure 11–3 provide the details about cabling the second
shared SCSI bus and member systems 2, 3, 4, and 5 into the cluster.
Section 11.2.3 and Figure 11–4 provide the details about cabling the third
shared SCSI bus and member systems 1, 6, 7, and 8 into the cluster.
______________________ Note _______________________
You can install Tru64 UNIX and TruCluster Server Version 5.1A
after you complete member system 1 and 2 hardware installation,
or you can wait until the hardware for all the systems is installed.
