this production server is an legacy.
my seniors taking over from the previous vendor, did not even do any mksysb backup until i join and ask them to do it.
First off: no problem. I have seen worse, so stay cool. You can handle that.
The first thing you need to explain (to your seniors) is: taking an mksysb is not changing or even doing anything to their precious production server. Getting a working mksysb image in fact enhances runtime security. Here is how to do it correctly:
1) on your production server create a file "/etc/exclude.rootvg" where you put in all the directories you do not want to have in your mksysb-image. Possible contents could be:
2) Issue the mkszfile command. This generates a file called /image.data in which the layout of the FSes, LVs, disks, etc. is described as it is used by the mksysb-command. You need to edit this file prior to running the mksysb itself to remove LV-copies (mirrors) and the like. If you need help there: just post the file and we can go over it.
3) Only after adapting both these files run the mksysb-command, exactly as follows:
Note that you do NOT use the -i flag, which would overwrite the /image.data file you edited, voiding your edits.
The resulting mksysb-image should fit onto a tape and you can subsequently install it onto another system. If the resulting restore is not to your liking: finetune the process by excluding more directories, etc.. You can do this over and over again without changing your environment itself in any way.
I hope this helps.

Hello Guys,
Can before and after snapshots be used to verify successful filesystem restoration?
snapshots will be created using fssnaps and restoration is thru legato restore?
Any ideas on this? or any other ways I could verify that restoration is good?
