d. Boot the system from the alternate boot path, where the CSLT is mounted.

b. Enter Y to the Interact with IPL? prompt, if it appears on your screen.
The system boots from the alternate source (tape). After some tape activity, the
ISL prompt displays.
e. Update with your backup CSLT.
ISL>UPDATE CONFIG
If you are backdating with a CSLT, UPDATE CONFIG brings in the boot and system
files from your previous release, as well as your previous configuration files.
f. Monitor progress messages.
While the UPDATE process is taking place, it is important that you monitor the
process at the console. Note any errors that may be reported to the screen for future
action.
If you modified your configuration after updating to Release 5.5, you may need to
check the configuration when the backdated system is up and running normally.
These changes may include I/O changes and other changes made to logging events or
miscellaneous configuration changes.
If configuration files reside in groups other than the CONFIG group, the system will
not have the proper configuration when booted after updating from the CSLT. If your
configuration files are in a group other than CONFIG, you must restore them now and
reboot the system.
Updating with your CSLT ensures that any patches that had been applied (from a
PowerPatchtape) which changed NL.PUB.SYS, XL.PUB.SYS,orSL. PUB.SYS will still
be in effect. Also, any additions made to these libraries as a result of SUBSYS
products having been installed will be there as well. Contact the Response Center or
your HP representative for information about applying patches to a backdated
system.
g. Confirm the date and time.
h. Boot the system from the primary boot path.
a. Boot messages can vary, depending on the system model.
b. Enter Y to the Interact with IPL? prompt, if it appears on your screen.
The system boots from disk. After some activity the ISL prompt displays.
