Mounting Drives from a Failed System

[mrunix]

Our NCR 3455 from 1991 crashed. The diagnostics say the main system planar board failed. We had 5 h/d's. Can you mount these on another system to retrieve files?

many thanks in advance,

chris

Depends on the filesystem used on those HD, whether any type of RAID was on place, and on the type of HD.
SCSI would be easier, but if other than IDE/SCSI it may be hard to do unless you have another NCR 3455 at hand.

If you have another 3455 then it should be possible.

What was the OS and version on it?

/stand bfs
/usr2 ufs
/select ufs
/dasdata ufs
/usr3 vxfs

hmmm, i don't even see the NCR 3455 on ebay anymore.

ncr unix mp-ras 3, which is SVR4.

can you hang the drives in another box, mount them and get the files?

many thanks for any help in advance,

chris

I assume the drivers are SCSI. If not then you may have problems.

With those filesystems you will probably be able to do it, but you still haven't told us if you had any RAID in place.

What you mentioned seems to be the mount points, and respective FS.

Do you also have the HD configuration?

Hi,

This might be a stupid question but; do you not have backups from the syste? If so, you could play them back to a different backup client.

first of all, thanks for the replies.

1. no raid, 50 pin SCSI

2. we have backups, but they belong to the system whose hardware failed and can't/shouldn't be replaced ( too old ).

3. we are recovering the database through the database s/w company.

4. the files we need are miscellaneous .txt files from other directories, we still have the h/d's

many thanks in advance,

chris

Why can't you restore those backups onto a different system?

Chris,

You mentioned that the Databases are being recovered by the DB company.
Does this mean that
A) They are acessing the HD directly
B) You have working backups and these are being restored by them to another machine

Any of the above should allow you to recover the files you need.

And finally do you need further help or are you sorted?

OK, don't laugh.

The DB company took our QIC drive and tapes, and are reloading the s/w and the database to a fresh install.

The drives I pulled out of the server in the hopes of hanging them in, maybe FreeBSD to just read and pull off files like awk command files and WP letters and such.

So, no not just sorted out yet.

Many thanks to all for the help,

chris

And they you didin't have those files on the backup? tsk tsk..

Get a Linux machine with SCSI, connect the guys, and be very very carefull with what you do, and mount them using the Linux tools available. (Unixware 7 is also able to do this).

IF you are not familiar with this stuff get some that is to do it for you. if you do not understand what you are doing you may overwrite the information on the HD.

(Where are you based?)
