Recommended Patches - Extension Software
HP recommends that you install the patches from Extension Software. Extension
Software is a DVD that contains HP-UX core patches for each version of HP-UX. The
patches in the bundle have been tested as a single unit and therefore the possibility of
conflicting patches is minimized.
Installing Extension Software
1. Put the “HP-UX Extension Software” DVD into the DVD drive.
2. Make sure the DVD drive is mounted:
/usr/sbin/mount
If there is no entry for the DVD drive, mount it:
/usr/sbin/mount /dev/dsk/devicefile /your_mount_directory
3. Read (or print) theREADMEFIRSTon the DVD prior to installing the patch bundles:
cd /your_mount_directory
more READMEFIRST
This file contains warnings, installation instructions, and the list of patch bundles.
Removing Patches
On a standalone system, type the following command to remove individual or multiple
patches:
/usr/sbin/swremove -x auto_reboot=true \
PHxx_yyyy.PHxx_yyy...[PHxx_yyyy.PHxx_yyy...]
