make_recovery

Hi people,
I've created a boot disk on the server using the make_recovery. And only the server has the tape drive and the rest of the clients just share the tape drive.
And now, one of the client couldn't boot up. Can I boot the client by using the make_recovery tape from the server site?
What should I do in this case?
Thanks.

Hi June

first it is advise to do the make_recovery for all the system in each tape .

second - you can buy the product ignite - server that will give you the ablilty to do the backup by net in a sigle ignite-server .

about your que. , if the computer that you made a recovery tape is the same of the computer that have a problem .

you can also boot the system from the recovery cd and will give you the ablilty to fix the error that you have in the computer ( you didnt tell what is the problem with the computer )

to boot from the recovery cd you need of course a cd in the computer , the cd is the same of the install core cd .

just choose the option recovery cd and then you can choose to boot the cd from the cd and over there you can do your trubleshoot of the problem .

be advise that there is a few option after you recover from the recovery cd .

one more advise - as you wrote about the config of your site i thing that ignite-server that have a tape device is the best option .

When you mention: sharing the tape drive, I am guessing that you are not moving the cable from computer to computer, but using networking to share the tape. The answer is no, there is no way to boot any tape over the network to another machine.

This brings up a good point. When HP-UX is running, then networking is available and you can access the tape, although not transparently. But if the remote machine cannot boot, the remote tape is useless and that is a big problem.

However, Ignite/UX comes with two flavors: make_tape_recovery and make_net_recovery (if you are using make_recovery, download the latest version). The make_net_recovery tool allows you to create a network-bootable image which most (but not all) 9000's can see from the processor ROMs. Ignite/UX is a free product.

Hi,

There are two simple methods to do this.

To make the recovery tape for the server
you are on:

# make_recovery -ACvd /dev/rmt/0mn

TO make an image that can used for other
HP-UX servers of the same class

# make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn
The -I option allows you to install on
another server interactively.

Note the no rewind device that MUST be used.

HTH
