Enter Y to confirm restarting the system.
d. If the system does not respond, press the reset button, key switch, or on/off switch as appropriate for
your system.
e. Boot the system from the alternate boot path, where the CSLT is mounted.
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 the alternate source (tape). After some tape activity, the ISL prompt
displays.
f. 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.
g. 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 7.5, 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.
NOTE 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 PowerPatch tape)
which changed NL.PUB.SYS, XL.PUB.SYS, or SL. 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.
h. Confirm the date and time.
i. 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.
4. Start the system.
