Re: console hungs

Hi,

Run the following command on the command line to "reboot" the GSP (without rebooting the server):

#stty +resetGSP < /dev/GSPdiag1

Re: console hungs

See KB UCMDSKBRC00009102 - "Hung Console : applies to all HPUX Servers with standard console" how to deal without reboots.

Check also required patches/firmware upgrades.

Refer to :

http://docs.hp.com/en/A5191-96018/ch04s02.html

You can also reset the GSP thru a small button at the back of the server.

If the GSP becomes hung, it is possible to reset the GSP without impacting the server. The GSP may be reset via the GSP RESET button on the right side of the card. The PCI cover panel (right side panel) must first be removed to allow access to the right side if the GSP card.

Re: console hungs

but if you can get the CM prompt, i doubt the gsp has hung. the console hung could be due to system is totally hang since your telnet to the system is also hung. if no other way you can access to the system, you may do a TC at the CM prompt to reset the server which will be followed by a TOC dump onto the dump space. the files in the /var/adm/crash can be sent to HP for analysis on the root cause of the system hang.

Re: console hungs

Did you try to connect to the server's IP instead of the GSP IP?
I'm not sure about this.

Hope this helps!
