Make_tape_recovery

[Learn_1]

running HP-UX11i on rp7410.disk system 2300 is connected with server via RAID4Si controller.I want to backup system disk which is on local disk not on disk system 2300.for this i will use the following command
make_tape_recovery -x inc_entire = vg00

i want to confirm this command before applying it.will i have to go in single user mode and then from there i should run this command.similarly if i go to single user mode then whether this command will be available as this is on /opt.
Please mention the exact procedure to create make_tape _recovery for system disk.Also please mention whether this will affect the disks on Disk system 2300 or not.

I always use:

make_tape_recovery -Av

[Pete Randall]

make_tape_recovery -a /dev/rmt/Xmn -I -v -x inc_entire=vg00

is what I always use.

Your command looks fine, but I would add to it a bit. Here is what I use regularly:

# make_tape_recovery -a /dev/rmt/0mn -I -m tar -v -x inc_entire=vg00

You do not have to go to single-user mode to do this. I do it regularly in multi-user mode, though we do run this on Sundays when the systems are fairly idle. It is best to run it at a time when there is not much activity on the system.

No this should not affect your disks on the DS2300. If vg00 is not on them, then it won't really even look at them.

If your tape is /dev/rmt/0mn this is exactly what you want, no need for single user mode.

(no spaces before and after the equal sign, though).

Maybe you want to consider adding the "-I" option for an interactive recovery. This will halt recovery after boot from tape and give you options to change (e.g. the size of the root filesystem).

without -I you have 10 seconds to interrupt automatic recovery (which is good for "just put the tape in boot and let it run"

Hello!

Try this, work for me:
make_tape_recovery -a -v -I -m tar -x inc_entire=vg00

thanks for your replies.
just want to confirm that can i run this command and create backup while the system is running or will i have to boot from cd and then run this command to backup system disk.if on running system what about the open files.

[Patrick Wallek]

Boot from CD to do a make_tape_recovery? Goodness NO!!!!

Just run it from multi-user mode when system activity is light and you will be fine. Don't worry about open files, especially if you are just doing vg00. The tape will be fine! I have never had a problem with running make_tape_recovery from run-level 3.

[John Meissner]

you can run these commands when the server is up and running.

[Geoff Wild]

You can cron it as well - we run ours "live" - no need to go to single user mode. If you have an ignite server - then you can run it remotely and store the image on the ignite server:

30 11 * * 5 /opt/ignite/bin/make_net_recovery -s igniteserver1 -x inc_entire=vg00

when we create this tape and recover by using this tape ,the disk2300 configuration is not being restored.therefore the disks configured in the disk system are not accessible and goes to unavailable or offline.
what should we do so that we when we recover by using this tape.the disks configured in the disk system also become availble.
note that we have disk system 2300 connected with the system via RAID 4Si SCSI controller.

Hi,

You haven't mentioned the version of Ignite you are using. Support for the RAID 4Si card started with 3.2 onwards.

Also, you may need to interact with the recovery and manually configure the card. This is possible by going to he Advanced Options tab and selecting the "Configure A5856A RAID 4Si cards" button which will run the "irm" utility to configure the card.

I would use the following command:

make_tape_recovery -A -a /dev/rmt/0mn -I -x inc_entire=vg00


Cheers!!!
