make_tape_recovery flags

[Semaj Mot]

Greetings! The answer to my question is probably very obvious but I'm having no success finding it.

Prior to our upgrade to 11i, I used the following command to create a bootable system recovery tape:
/opt/ignite/bin/make_recovery -ACv -d /dev/rmt/2m


Now that were running 11i, I want to use make_tape_recovery. My question is, what flags used with make_tape_recovery are the equivalent to the -A and -C flags of make_recovery?

I searched the manual page for make_tape_recovery and discovered that the -d (destination) flag was replaced by -a, and that the -v (verbose) option hadn't changed. But I didn't find any mention of which flag to use to specify that the entire root disk/volume group be included (which was option -A with make_recovery) or which option created the system status file /var/opt/ignite/recovery/makrec.last (flag -C was used to perform this task with make_recovery)

I find it hard to believe that HP would remove these particular options, but I suppose it's possible.

In any case, if someone out there has information on this issue, I would enjoy hearing from them.

Thank you for your time.

Hi:

The easy way to capture all of vg00 is this:

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

Don't confuse the '-i' option of the old 'make_recovery' with the '-i' option of its replacement, 'make_tape_recovery'. The '-I' option of 'make_tape_recovery' is the *same* as the '-i' option of 'make_recovery'. '-I' means cause the Ignite process to be interactive when booting from tape.

There are additional include and exclude options available. Remember that man pages are included with each download of Ignite software so consulting them will provide you with knowledge of any new options too.

Regards!

Hi,

To get all of vg00 use
-x inc_entire=vg00

I can't seem to find the equivalent to -C.

There is no equivalent to make_recovery -C in make_tape_recovery. Whenever make_recovery is finally obsoleted, that option will go away.

The '-C' option adds a lot of time and overhead to the tape creation process that really isn't necessary.

My view is, if you think you need a new make_tape_recovery tape, then you do. Go ahead and make it.

Hi (again):

The '-C' option of 'make_recovery' was intended to allow a 'check_recovery' to be run to determine what had changed since the last recovery tape was made and therefore if it was necessary to make another recovery tape.

The 'check_recovery' feature has been deprecated. It's overhead was not deemed worth it. Making Ignite recovery tapes routinely is simply desireable insurance.

A gratuity of 'make_tape_recovery' is that you get a current "manifest" of your server: '/var/opt/ignite/recovery/latest/manifest'.

Yep, Patrick's correct.
Since -C was only used for check_recovery which is obsolete now, it appears there is no longer a need for it.
