HP Tru64 UNIX Technical Updates for the Version 5.1B and Higher Operating System and Patches (February 2010)

In a future patch kit, these tunable variables will be implemented as kernel subsystem configurable
attributes, accessible through the sysconfig command.
Patch Kit 2
The following notes pertain to Patch Kit 2.
Installation Problem on Cluster Systems Running Patch Kit 1 (Aug. 2003)
TruCluster Patch 7.00 will not be installed if you install Patch Kit 2 on a TruCluster system
running Patch Kit 1. To work around this problem, take one of the following actions:
• If you have installed Patch Kit 1 but have not yet installed Patch Kit 2, remove TruCluster
Patch 7.00 before installing Patch Kit 2.
• If you have installed Patch Kit 2, remove TruCluster Patch 7.00 (which was installed with
Patch Kit 1) and then install Patch 7.00 from Patch Kit 2.
Removing Patch May Create Problem with vrestore Archive (July 2003)
Patch 685.00 in Patch Kit 2 installs Version 5.1 of the vdump and vrestore utilities. If you use
that version to create an archive and then uninstall that patch, attempting to restore the archive
will fail with the following message:
vrestore: Need vrestore V5.1 to restore contents: terminating
This occurs because by removing the patch, vdump and vrestore revert to an earlier version,
which does not recognize the Version 5.1 archive.
To restore the archive, you will have to reinstall Patch 685.00 or install the binary file for vrestore
included in Patch Kit 2.
Problems with /sbin/dsfmgr Versions (Mar. 2003)
When downgrading to an earlier version of the Tru64 UNIX operating system (for example, by
uninstalling a patch kit or installing an earlier version of the operating system), an older version
of the device special files manager, dsfmgr, may have problems reading the newer version the
dsfmgr .dat files. When that happens, you will see a message such as the following during the
boot process:
dsfmgr: Error: cannot open and read file /etc/dfsc.dat
Bad status file data/format
dsfmgr: Error: cannot open and read file /etc/dfsl.dat
Bad status file data/format
bcheckrc: Device naming failed to boot configure or verify.
Please correct the problem and continue or reboot.
Uninstalling the Patch Kit
If you made the following changes to your system after installing the patch kit, you will have to
undo those changes before you can uninstall the patch kit:
• If you changed your hardware configuration (for example, by adding a new disk), the system
configuration that existed prior to installing the patch kit might not recognize the new devices
or may not provide the necessary support for them.
• If you added new cluster members, the new members will not have an older state to revert
to if you attempt to uninstall the patch kit.
To uninstall the patch kit, do the following:
1. Remove all new hardware and new cluster members that you added after installing the
patch kit.
2. Run dupatch to uninstall the patch kit.
3. Verify that the patch kit was successfully uninstalled.
