HP Tru64 Unix Release Notes for Version 5.1B-6 (5900-1150)

Script Must Be Run When Returning to Prepatched System
If removing this patch kit restores your system to a prepatched state, you must run the /etc/
dn_fix_dat.sh script before rebooting your system during the patch-deletion process.
This situation occurs if Version 5.1B-2, or higher, is the only Tru64 UNIX patch kit installed on
your 5.1B system.
NOTE: Because the no-roll procedure automatically reboots the system after deleting the
patches, you cannot use this method to delete this patch kit if doing so returns your system to a
prepatched state.
Failing to run this script results in your system being unable to boot normally. If this occurs, do
the following:
1. Boot your system in single-user mode:
>>> boot -fl s
2. Run the dn_fix_dat.sh script:
# /etc/dn_fix_dat.sh
3. Reboot normally.
If you also need to reverse the version switch as described in “Script Required to Reverse Version
Switch”, run the /etc/dn_fix_dat.sh script after step 5 in that process.
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 prepatched state
NOTE: If during the dupatch installation and deletion processes you see a Special Instruction
about running the /etc/dn_fix_dat.sh script, you should ignore that instruction unless your
system meets the requirement described here.
