Re: Attach San Disk to Tru64 then to HP-UX
then I doubt that an HP-UX system would
understand its contents. There might be some
basic UNIX file system which both systems
might understand, but if you're not already
using it, then the conversion time might
outweigh the benefit of simply switching the
disk over.
> [...] avoid using NFS [...]
There are many ways to avoid using NFS. One
example: a "tar" pipeline using
remsh/rsh/ssh. That would still involve the
network, of course.
Regardless of the method you choose, I'd run
a test on some non-critical data before I
trusted any scheme to do the right thing with
any valuable data. Moving the disk would
certainly add danger which copying its
contents would not.

Can't I just create a new filesystem with this filesystem type and dump the data in there ? that way I wont have to convert my whole Tru64 system to this type. Is that possible?
Yeah, I know about the tar, we are just trying to avoid using the network and opt for a faster way (deatching/attaching of disks from san) if possible.

On some new disk, sure. I assume that UFS
is the thing to use on the Tru64 side. I
haven't looked at HP-UX closely enough to
know anything. I use AdvFS on Tru64, and
"vxfs" (or whatever the complex thing is
called) on HP-UX, so I've never tried to do
anything like this. It should be relatively
easy to run a small experiment.
But if you need to copy the stuff once from
AdvFS to UFS, and again from UFS to whatever,
then a network method might start to look
more attractive.

Re: Attach San Disk to Tru64 then to HP-UX
This is a one time procedure, as we are basically migrating, we wont be doing this much. I will try to run an small experiment:
1) Attach a disk to the Tru64 box
2) Createa UFS file system type on this new disk
3) Dump the data to this filesystem
4) Detach the disk from the Tru64 box
5) Attach the disk to the HP-UX
6) Mount the file system
At first, I dont see UFS on HP-UX, but will search a litle bit. I will let you know how it goes.
Thanks again.

Re: Attach San Disk to Tru64 then to HP-UX
I still know nothing, but these could be
interesting:
man 1m mount
man 1m fstyp
I'd guess that "hfs" is about as close as
you'll find. Note that large-file capability
is optional on HP-UX. (The "64" in Tru64 did
have some benefits.)

Re: Attach San Disk to Tru64 then to HP-UX
I think better would be take the backup on tape and create file system and restore the data from tape.

Re: Attach San Disk to Tru64 then to HP-UX
Would tape be better than the network?

Re: Attach San Disk to Tru64 then to HP-UX
I think Jaoquin is avoid using network in that case I think tape is pretty feasible in this.

Re: Attach San Disk to Tru64 then to HP-UX
And why would that be? Because it's slower?
And tape would be faster?
