HP announced that the HP ITRC is to undergo maintenance late in May, during which time the ITRC will be read-only.
Maintenance will start on May 19 at 6:30 am GMT, and end on May 22 at 3:00 pm GMT. During the time that ITRC is read-only, no new forum messages can be posted, and no changes to user profiles, favorites, or notifications will be possible.
All of those that use HP support should be using HP ITRC as much as possible; I’ve found that the HP-UX and OpenVMS support is fantastic. There is quite a lot of expertise behind the readers and responders of the forums.
