Hello Gurus,

        Sorry for the late summary. My question was:

> How do I mount/move an AdvFS disk on another machine(with DU4.0B)?
> What are the steps involved?

Here are the suggestions:

*1
cd /etc/fdmns
mkdir name_of_the_domain
cd name_of_the_domain
ln -s /dev/rzxxxxc
mkdir /bigdisk
mount name_of_the_domain#name_of_the_fileset


*2

Use advscan to create the link structure for the domain and then
mount file system just as you would elsewhere. If the particular
domain and fileset are already in use, recent versions have an
option on mount (as I recall) to allow mounting the file system.
On older versions you'd have to rename the domain.


*3

- Make sure that you don't duplicate disk IDs when you move the disk.

- On the target machine BEFORE the move, run scu and issue a "show edt"
command to see what's out on those busses.

- Power down, change the ID on the disk if necessary, install in the target
machine and power up. Either do a show device at the console or rerun the
scu command (after booting) mentioned earlier to make certain you see the
"new" disk. 4.0x automatically creates the new special device files in
/dev. No need to rebuild the kernel. You will need to identify the new
device name for later use. An ls of /dev/rrz*a before and after the change
would probably be the simplest method.

- then follow the above mentioned steps(*1 and *2).


Thanks a lot for the help,

Jacob Rajan.
