Boot from a different kernel.

TechC — Tue, 27 Feb 2007 10:44:06 GMT

Hello,
I am getting an error when booting my HPUX 10.20 workstation. Says "exec failed cannot find /standvmunix or /vmunix" I tried booting from kernel.prev and kernel.bak and they both give a not found error. Is there any way to boot from a kernel say from tape, or can I use the install media to put a kernel in place. Would like to avoid ignite if possible. Any suggestion would be appreciated.
Thanks
James

James,

From the ISL, you should be able to find out the list of files in /stand by running the "hpux" command

ISL> hpux ll

This will list the kernels and other files available in /stand.

The kernel is usually named vmunix.prev. First, find out if there is a vmunix.prev by running the above command. If you find any, then

ISL> hpux /stand/

Mr. Sundar,
Thank You for replying.
The output of the command is.
./
../
lost+found
build/

Thanks
James

oh, you are probably out of luck. I guess someone has wiped off the /stand clean. I havent tried this before but see if this works

# hpux /stand/build/vmunix_test
