When I am trying to boot the server I am getting below O/P
ERROR: Your system crashed before I/O and dump configuration was complete.
A crash dump cannot be taken under these circumstances without
special configuration. Contact your HP support representative.
Could you please help me to resolve this issue

If you are not able to boot the system then where from you got the above outputs? Have you booted the system in lvm maintenance mode ?

Or you rebooted the system since it has the above problems and now system is not booting at all ?

Please share all these details and give some background about the activities performed before reboot.

Thanks a lot for your valuable replays. I have booted the system in lvm maintenance mode and I collected above O/Ps. Servers is up and running now. I have switched off the server for some time after that its came up.
