HPUX Patch naming conventions

HP release OS patches for HPUX every 6 month i.e. twice a year. For smaller HPUX patch which are releases as on need basis HP follows below naming conventions

Patch name format is PHxx_yyyy


xx = area of patch
CO : General HPUX commands
KL : Kernel patches
NE : Network specific patch
SS : all other subsystem patches

yyyy = unique number

From patch name you will be able to guess area of its impact so that you can plan your activities accordingly. If patch requires a reboot or not can be determined while downloading patch from HP portal itself or even by running swinstall command with -p (preview) argument.

HP patches are available on http://software.hp.com/ which will redirect you to HP software depot home. HP passport login required to download patches or software from software depot.
