Re: mount error

Hi Mike,

Thanks for the good info. Do you have more suggestions? How do I boot with single user-mode?

Hi Guys,

Can I used the tool like;

Re: mount error

Hi,

from CRM console

#init -S
will take you to single user mode


first check with "verify" command, if any issues fix the problem using 'fixdomain" command.
There wouldn't no any impact on using these commands
never give up

Re: mount error

hi guys,

Is there any other ways to recover my data, heres the situation:

a) I have three (3) disk configured as one file domain ( rz1c, rz2c, and rz3c)

b) When I try to execute the command "verify" my systems reboots automatically.

c) Furthermore, when I execute the command "salvage" in order to at least get the data, an error displaying " I/O error"

What will I do next? Their is no yet available command "fixfdmn" in TRU64 4.0E.

Help me. :(

Re: mount error

Hi,

when the server reboots on verify then the domain is damaged beyond repair.

Sorry, but it looks like you will have to rebuild and restore.

Re: mount error

It might be worthwhile investigating the "I/O error" first. It could be that it can not access one of the disks in the domain (e.g. a disk that is not properly seated or a disconnected cable, etc.). If you can fix the "I/O error" (without having the disk replaced), your domain might be able to come back up again.

Re: mount error

Hi Marvin,

it seems to be a hardware error.
It's possible that the error is not the disk, like a scsi controller o something like that.

Can you list the output of:
#>scu show edt
in order to check the disk status?

Can you check for an error with:
uerf -R

Regards.

Re: mount error

Hi,

you should check for errors in binary.errlog and check the disks with
dd if=/dev/rrz1c of=/dev/null bs=1024k
Do you use any mirroring?

greetings,

Michael
