HP Tru64 UNIX Release Notes for Version 5.1B-4 (13157)

Enabling the Version Switch After Installation
Some patches require you to run the versw -switch command to enable the new functions
delivered in those patches. (See the Patch Kit Installation Instructions for information about version
switches.) Enter the command as follows after dupatch has completed the installation process:
# versw -switch
The new functionality is notavailable until after you reboot your system. You do not have to run
the versw -switch command, but if you do not, your system cannot access the functionality
provided in the version-switch patches.
Script Required to Reverse Version Switch
If you enabled version switches as described in “Enabling the Version Switch After Installation”,
you must run the /usr/sbin/versw_enable_delete script before attempting to remove
Version 5.1B-4. The steps for running this script require a complete cluster or single system
shutdown, so choose a time when a shutdown has the least impact on your operations. The
following steps describe the procedure:
1. Make sure that all phases of the installation process have been completed.
2. Run the /usr/sbin/versw_enable_delete script:
# /usr/sbin/versw_enable_delete
3. Shut down the entire cluster or the single system.
4. Reboot the entire cluster or the single system.
5. Run dupatch on your single system or on a cluster using the rolling upgrade procedure to
delete Version 5.1B-4 (as described in the Patch Kit Installation Instructions), up to the point
where the kernel is rebuilt and the system must be booted.
6. Reboot the single system or each member of the cluster.
NOTE: This step requires that you reboot each cluster member to remove Version 5.1B-4.
Because the no-roll procedure automatically reboots the system after deleting the patches,
you cannot use that method to remove the kit.
Restriction on Using No-Roll Procedure to Remove Kit
The section titled “Script Must Be Run When Returning to Prepatched System” describes actions
you need to take before rebooting your system if removing this kit would restore your system
to a pro-patched state. Because the no-roll procedure automatically boots your system, you cannot
use that patch kit removal method if doing so would restore your system to a pre-patched state
Do Not Install Prior NHD Kits on a Patched System
Do not install the NHD-5 or NHD-6 kits on your TruCluster Server system if you have installed
this patch kit or earlier patch kits. Doing so might cause an incorrect system configuration. The
installation code for these new hardware delivery kits does not correctly preserve some cluster
subset files.
General Release Notes

workarounds you can use.
