INIT: no more processes left in this runlevelRedhat 5 and 6 have begun to hang on shutdown/reboot
Some QAS libraries are owned by "init" causing the /opt file system not to unmount cleanly during a reboot.The issue occurs when the following conditions are met:
1. Redhat 6 Linux.
2. /opt is on a separate file system
3. vas3 is behind files in the nsswitch.conf file -
Cause
The default path /opt/quest is mounted froma remote drive.
Rebooting the machine goes through unmounting any shared drive before stopping the vas services; which should be the other way around.
Stop VAS and unmount drive in this scenario.
-
Resolution
This is an OS issue, not a VAS issue. To fix it, move vas3 behind files in nsswitch.conf.

Additional Information
Thats it - system needs to be switched off by force. It seems to berelated to the NSSwitch-component:
vastool unconfigure nss
--> Reboot OKvastool configure nss
--> Reboot hangs
