Make_net_recovery move to tape

[RonVH]

Hi
Does anyone know the best way or command used to take a network recovery of server A, that is stored on server B, then make it into a tape I can put in back into server A to do a recovery.

I think you are looking for the command

make_medialif

but the use of it might not be as simple as copying the net recovery image from disk to a tape, but a little more complicated. This page has pointers to two different solutions that you might be interested in:

good luck.

To recover A, why not just network boot it from B ?

Or maybe there is some reason not to ?

You could create a boot helper tape by executing 'make_tape_recovery -I' from B, use the tape to boot A, then choose the network restore option during install.

If A and B are in the same subnet, it is easier to recover A from B directly.

One thing to note:
On most our systems the network recovery never seems to work due to the fact that lan0 needs to be the nic that is on the same subnet as the network ignite server or the server is not on the same subnet entirely. Which is why we want to move the image to a tape.

Ron,

There is a concept called boot helpers. Details elude me right now, but you can find them in the ignite cookbook. Set one up where your lan0 is located (on another server that is) and use that one to boot from, i.e., boot lan.X.Y.Z.Q where X.Y.Z.Q is the ip address of your ignite helper, then point the process to download the ignite image from your main ignite server, provided ftp/tftp is allowed between lan0 subnet and the ignite server's subnet.

I have done this in the past but it was a long time ago and old age is catching up with my memory.

Hope it helps.

Hi,

Yes. You need boot helper to recover the system if clients are in different subnet.

Refer this on how to configure boot helper.

Thanks all for your help. Here is the script we developed to do the tape automatically for us:

#!/usr/bin/sh
# tape recover from net image.
