Hello list! I've got a new server Hp9000 D310 with HP-UX 10.20. Installation of IDS 7.30.UC8-1 was succesful.

The installion nodes said to install some another patches: PHSS_13421 -> On HP web-page I've got PHSS_17907 After installation of PHSS_17907 the server hangs after reboot ( stty Not a typewriter, (after DHCP)) What patches must I have???? At the moment I recover my server with backup. Thanx in advance. Dirk Emmermacher
