hy,
Do you have the crash dump? Some of the things that you can do is

1. From the console prompt do things like
show ????
do a help if you need to know your
options.
Look out for any environment errors etc

2. After the system is up, you can always
look at your errorlog and dump
(if present) using the stack dump anal
ANAL/SYS

Hello,

It's look like there's a problem with the metadata for the /oracle.

Cheers

hy,
Looking at the timestamps of the errors i posted in my previous message, it looks like they are pretty old, dated as far as Oct ?

Are we missing something

it seems you have a problem with your hsz50.
Can you post

show disk full
show mirror
show fail

thanks,

Michael

Thank Mobeen,Nicolas and Michael.Now the system is running and the hsz50 is being used.Then can "show this fulls","show other (if redundant)","show disk full","show mirror" and "show fail" be used when the hsz50 being used?And do you need me to provide other messages?Thank you.

[Mobeen_1]

Hy,
No problem. You can use all the show commands that were requested without any issues on a running system. Trust me for that :-). Go ahead and give us the details
