recommends that you run UETP after an installation or if new hardware was added as part of
an upgrade.

Before using UETP, you must create a SYSTEST (standalone system) or SYSTEST_CLIG (OpenVMS
Cluster system) account. You should also create an account for HP service representatives to
use. You can use the CREATE_SPECIAL_ACCOUNTS.COM file to create these accounts, as
explained in HP OpenVMS System Manager's Manual, Volume 1: Essentials.

For complete information about using UETP, see the HP OpenVMS System Manager's Manual,
Volume 2: Tuning, Monitoring, and Complex Systems
.

7.21 Backing Up the Customized System Disk and Initiating Systematic
Backups

After you customize the OpenVMS operating system to your satisfaction and perform the other
steps recommended thus far in this chapter that are relevant to your system, protect your work
by making a standalone backup copy of the system disk to tape. To do so, follow the instructions
in

Section 7.2 (page 127)

. If you are going to be saving to disk, specify a disk that will not be (or

is not) part of a shadow set.

For complete information about backup operations, including a description of an alternative
method that does not require booting from the operating system media, see

Appendix F (page 301)

.

HP also recommends creating a systematic routine for backing up the application, data, and user
disks. For more information, see the HP OpenVMS System Manager's Manual, Volume 1: Essentials.

7.22 Reforming the Shadow Set as Final Postupgrade Backup

If your system disk participates in a volume shadowing environment, re-form the shadow set
again to generate another shadow copy onto the other disks in the set. To do so, follow the
instructions in

Section 7.7 (page 131)

.

7.23 Rebooting Cluster Members (Upgrades Only)

If you are performing a rolling upgrade in an OpenVMS Cluster environment and have completed
all the postupgrade tasks required thus far for your upgraded system disk, reboot each system
that boots from that system disk.

For more information about booting your system, see

Appendix A (page 167)

for OpenVMS Alpha

systems and

Appendix B (page 187)

.

At this point, your system is ready for general use.

7.24 Running AUTOGEN to Tune the System

When you install or upgrade the OpenVMS operating system, the system executes the
AUTOGEN.COM procedure to set the values of system parameters and the sizes of the page,
swap, and dump files according to the system configuration.

After running your system for at least 24 hours with users or a typical application workload on
the system, run the AUTOGEN.COM procedure again to tune the system properly. Run
AUTOGEN as follows. (In an OpenVMS Cluster, you must follow these steps to run AUTOGEN
on each cluster node.)
