Mounting disk on Tru64 system

[#1]

Hi All,

I want to mount a SCSI disk on Tru64.
I am able to see the disk using
hwmgr -show scsi command, but i don't know the domain name and fileset for the disk.
The disk contains a AdvFS filesystem.

Can anyone help me how to mount the disk.

I think you can use '/sbin/advfs/advscan' command on the disk name for this. Check the manpage for details.

# /sbin/advfs/advscan dsk3

Scanning devices /dev/rdisk/dsk3

Found domains:

*unknown*
Domain Id 4600e1a4.000541d0
Created Wed Mar 21 13:11:24 2007

Domain volumes 1
/etc/fdmns links 0

Actual partitions found:
dsk3c*
*unknown*
Domain Id 3776e099.00086640
Created Mon Jun 28 08:10:25 1999

Domain volumes 1
/etc/fdmns links 0

Actual partitions found:
dsk3g*


How to mount it?

Can you post the output of 'disklabel dsk3c'?

Hi Venkatesh,

Here is the output:

Ok, if you are sure that this disk alone constituted a AdvFS domain, you could try the following:

1) # cd /etc/fdmns/
2) # mkdir test_dom ; this would be the name of the advfs domain
3) # cd test_dom
4) ln -s /dev/disk/dsk3c

Now try "showfsets -b test_dom"

If the previous steps were successful, you should be seeing one or more fileset names as output.

If say you get a fileset name as 'xyz', then you could mount it on to an existing mount directory (say., /mnt) using:
# mount test_dom#xyz /mnt

Let me know how it goes.

It doesn't work :(

I am getting following error:

# showfsets -b test_dom
showfsets: can't show fileset info for domain 'test_dom'
showfsets: error = Device busy

That error indicate to me that you are on the wrong disk. Are you sure that this disk is not part of an already mounted advfs file system?

Can you:
1) # cd /etc/fdmns
2) # ls -R

and post the output?

if u are able to see disk in
#hwmgr v d
that means disk is available.
second thing if u want to find out domain
#ls -lRt /etc/fdmns
check the link for dsk3.
it would show you the domain and fileset.
If nothing bad was done is disk you would be able to mount it easily.
