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:


    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


    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...]
