About update-ux
The update-ux command improves the usability and robustness of the
update process by eliminating many of the manual steps required by
swgettools in previous HP-UX updates. In addition to ensuring a safe
environment on the target system for the OS update, update-ux
performs these update preparation steps before initiating the update:
• Before updating from HP-UX 10.20, update-ux performs these
operations for you:
— Verifies that FibreChannel Storage is not on the system. If
present, it must be manually removed.
— Ensures that you are not updating a diskless server. You’ll have
to cold-install 11i on a diskless server, making it a stand-alone
system.
— Checks for minimal disk space in /, /stand, /opt, /usr and
/var on a system using LVM.
— Removes the no-longer-needed SW-DIST.RUPDATE fileset.
— Removes any 10.x patch information and 10.20 OS bundle
wrappers.
— Upgrades to JFS version 3 if needed.
• Before updating from HP-UX 11.0 or an earlier version of 11i,
update-ux performs these operations:
— Checks for minimal disk space in /, /stand, /opt, /usr, and
/var on a system using LVM.
— Removes HP-UX 11.0 OS bundle wrappers.
— Removes MirrorDisk/UX bundles prior to update.
If any requirements are not met, update-ux will display an appropriate
message and exit.
update-ux installs a new version of HP-UX Software Distributor (SD),
plus any patches to it, from the source depot before initiating an OS
update.
