[anoop_10]

Hi,

I have one rp-4440 with HP-UX 11.23(CFS- CLUSTER).After changing some kernel parametrs which required for oracle ,re-booted my server.But its not comming up ..started giving this error..

Entering single user mode now...
mkdir: cannot create /stand/current/krs: Too many levels of symbolic links
chmod: can't access /stand/current/krs
ERROR: Unable to read title of running configuration: KRS error code 2

So I copied some files(vmunix,mod,krs,.config,bootfs,mod,system)
from /stand/backup to /stand/current..

After that sytem is comming up to normal mode but stiil giving the error...





ERROR: Unable to retrieve module information from configuration
'current':
kc_kr_open_node(/kconfig/Modules): KRS error code 2
WARNING: Unable to load modules scheduled to be loaded at boot time:

ERROR: Unable to read title of running configuration: KRS error code 2

WARNING: Unable to read the currently booted kernel configuration in order to generate an updated system file. The system file may be out of sync with the booted kernel configuration.

Can you create a new kernel now?

mk_kernel

Hi,

What To Do
HP recommends that customers boot from a stable backup."

Shalom,

1) Boot off of vmunix.prev or whatever you named the previous kernel.

2) Put the parameters back to what they were.

3) Generate a kernel with sam or however you did it last time.

Note the default system boot point is off of /stand/vmunux , not /stand/current

Hi,

Something similar happened to me:

# kcconfig
ERROR: Unable to read title of running configuration: KRS error code 2

What I did (worked fine for me):

# kconfig -n "last_install"
# shutdown -ry 0

Rgrds,
