Copying data from one system to another

[Subbu Krishna]

Hello,

I have a N4000 connected to XP256 that is up and running. This is up for lease and we need to return this
to HP. I also have a new N 4000 with FC60 disk storage.

I need to transfer data from the old N to the new N.
Any idea ?...

Option 1 - Connect the XP256 and FC60 to the new N and do a mirror and then later break the mirror. I don't believe i have enough controllers on the new N to do this.

Option 2 - Tape backup and restore / copy the data over the network.

Aany thoughts ?.

Thanks for the help.

Hi,

The network backup sounds good to me. With 100base LAN cards it will be faster than tape.

Network backup will be the best.

The network backup is better, try this simple procedure and command:
cd to /directory to be backed up then,
find . -depth |cpio -ocB |remsh remote_servername "cd /destination directory; cpio -ivcmdB"

Go for the network backup. A possibility:

/usr/sbin/vxdump 0f - /dev/vgXX/lvYY | remsh '(cd /dev/vgXX/lvYY;/usr/sbin/vxrestore -rf -)'

This works on the vxfs file systems

I dont know wether you want to try this.Why dont you swap the controllers from the old N and do the mirroring as you wish and put them back once you have finished. Does this sound feasible.

[Dave Wherry]

How much data do you have on the XP? How many and what type of controllers do you have on each host?

By the way I would try to rework the deal and keep the XP and send the FC60 back.

Also, you posted this question twice in the hp-ux forum and once in the mass storage. Centralize, centralize.

Hi
Use NFS :
-
1. On the data server export the file system/s that you want the data from.

2. On the receipient server mount those file systems.

3. Cd into the mounted file system and :-
find . |cpio -pudvm /

Quick and easy.

Hi Subbu,

Even if the network backup looks attractive, I would go for a tape backup because this one would provide you with an extra copy of your data for archiving purposes.

It's one more step than network copying, but it's added safety for your data.

Best regards,

Dan

I would agree with Dan.
But you dont really need to restore from the tapes, that would take ages.
So, do a tape backup.
Copy the files over the network, using nfs or without.
Test your backup tape by doing a couple of restores.
