unable to boot the tru64 unix server from the SRM prompt

[sk.imran]

Dear Vladimir Fabecic,

I think this is due to missing file.

osf_boot

becuase in the it cant open osf_boot

is there in any way to copy the file from the cd or tape.

if it is possible ..please help me..

[Vladimir Fabecic]

Yes, there is a way to recover osf_boot.
First you need boot CD.
When will you have it?

[sk.imran]

Thanks..
I have already Tru64 Unix V5.1B Media

I tried to boot from media

and then in the Unix shell what are the steps to be performed ..please give the details..

and how to mount the dsk0 disk and how to copy the file from the media or tape device.

Please give the steps..

[Vladimir Fabecic]

Try:
# cd /etc/fdmns
# mkdir tmproot
# cd tmproot
# ln -s /dev/disk/dsk0a
# cd /
# mount tmproot#root /mnt
Then do:
# ls -al /mnt
and send output
In case of any error message, please post them.

as

# cd /etc/fdmns
# mkdir tmproot
# cd tmproot
# ln -s /dev/disk/dsk0a
# cd /
# mount tmproot#root /mnt

# ls -al /mnt
Output: only showing the two file and one directory as:

dwrxr-xr-x 3 root system 8192 Aug 27 06:16 .
dwrxr-xr-x 21 root system 8192 Oct 24 2002 ..
dwrx------ 2 root system 8192 Aug 27 06:16 .tags
-rx-r----- 1 root operator 8192 Aug 27 06:16 quota.qruop
-rx-r----- 1 root operator 8192 Aug 27 06:16 quota.user


I am not able to access the disk after mounting to /mnt

This looks like empty file system.

Very strange output of disklabel!
Only partition "a" marked as advfs???
Did someone play with this server?
As I can see from hwmgr output you have SWXCR RAID controller configured with 7 LUNs, probably JBODs.
Is everything OK with hardware (any amber lights?)
Were you able to mount "old root" or not?
What is the output of:
# df
