HP Tru64 UNIX Version 5.1B-2 and Higher Patch Kit Installation Instructions (March 2009)

and use one disk for the root and /var file systems, one disk for the /usr file system, and
one disk for the quorum; you will need six additional disk drives to use cloning technology.
Performing the Cloned Installation
To create an exact duplicate of your system on an alternate set of disk drives, you can find a
third-party program that will do it for you, or you can use the following list of tasks as a guide
for doing it yourself:
1. Download and extract the latest Tru64 UNIX version or mount the latest Tru64 UNIX version
CD to your Version 5.1B-3 or higher system and run the dupatch command to install the
latest tools, including the necessary cloning tools. See Chapter 3 (page 33) for more
information on installing the new tools.
2. Identify the alternate set of disks you will use for the new software
3. Partition the alternate drives so those partitions are as large or larger than the current drive
set
4. Duplicate all cluster file systems onto the alternate disk set. This includes cluster_root,
cluster_usr, and cluster_var.
5. Duplicate all member-specific root partitions onto the alternate disk set. (that is,
root1_domain, root2_domain, and so forth.)
6. Create the CNX partitions for all member root drives and the quorum disk (if it exists).
Be careful to ensure that the alternate drive CNX partitions reference the disk device number of
the alternate drives, not the drives used by the currently running operating system. For example:
A cluster comprised of two members has the following disk setup.
dsk0a: contains the cluster_root file system
dsk0g: contains the cluster_var file system
dsk1g: contains the cluster_usr file system
dsk2a: contains the member1 root partition
dsk2h: contains the member1 CNX partition
dsk3a: contains the member2 root partition
dsk3h: contains the member2 CNX partition
dsk4h: contains the quorum disk partition
Additionally, the cluster has five unused disks available to it (dsk10, dsk11, dsk12, dsk13, dsk14),
which are as large as or larger than, the existing system disks.
The spare drives are used as a duplicate, or “clone,” of the existing operating system and they
are mounted on a mount point called /clone” The steps are:
1. Partition dsk10a to be as large or larger than dsk0a
2. Partition dsk10g to be as large or larger than dsk0g
3. Partition dsk11g to be as large or larger than dsk1g
4. Partition dsk12a to be as large or larger than dsk2a
5. Partition dsk12h for the special size of a CNX partition
6. Partition dsk13a to be as large or larger than dsk3a
7. Partition dsk13h for the special size of a CNX partition
8. Partition dsk14h for the special size of a quorum disk
9. Build the CNX partitions for dsk12h, dsk13h, and dsk14h
10. Create AdvFS domains and file sets for all file systems (that is, alt_cluster_root,
alt_cluster_usr, alt_cluster_var, alt_boot1, alt_boot2.)
11. Use common UNIX commands to exactly duplicate existing cluster and member file systems
onto the alternate disks.
12. Mount all file systems in a hierarchical form on the mount point /clone.
When these steps are complete, the mount command will display output similar to the following:
