make_tape_recovery

Playing with make_tape_recovery today.

I'm under the assumption that the old: make_recovery -vCAd /dev/rmt/0m is the same as make_tape_recovery -vA ????

Hi,

The old 'make_recovery -ACvd /dev/rmt/0mn' is equivalent to 'make_tape_recovery -x inc_entire=vg00 -v -a /dev/rmt/0mn

The -A options under make_tape_recovery is different, but when you invoke the old routine it converts it.

This is interesting - the mirror disk lv's are marked as 2 (not included). I take it that this version still does not support mirroring.

You can still back up your whole vg00. If / when you have to restore your system from the tape, it will STILL NOT automagically restore the mirrors.

Here is the make_tape_recovery command that I use to back up all of my systems vg00:

/opt/ignite/bin/make_tape_recovery -a /dev/rmt/0mn -I -v -x inc_entire=vg00

make_tape_recovery seems to be behaving oddly.

I split the mirrors off to see if it would back up the entire volume group. It didn't backup the entire root volume from the primary disk. VERY ODD. Each volume still had a 2 next to it. Anyone got any ideas?

There's no reason at all to split the mirrors when making a make_tape_recovery tape. Try the command in my previous reply and you should have good luck. It has worked for me for several months without any problems.

What does the -A option do, none of your examples use it?

If you don't use `-x inc_entire=vg00` then the whole vg00 will not be backed up?

I currently use:

/opt/ignite/bin/make_tape_recovery -A -a $TAPEDRIVE

I guess I should add `-x inc_entire=vg00` to this?

Sorry about jumping in here I just want to make sure I am also getting a good ignite backup of vg00.

hmmmmm

the only reason I split the mirrors was to see if the behaviour differed when using split mirrors. It did. It's just that I'm currently getting conflicting results from the make_tape_recovery process. It is marking all of my LV's with the number "2" which is not included. Just weird is all.

[Scott Van Kalken]

oops - just READ THE DOCS!!!!! 2 is fully included. doh!
