Full Discussion: Mksysb restoration
Operating Systems AIX Mksysb restoration Post 302976645 by bakunin on Saturday 2nd of July 2016 09:58:54 AM

When you issue the mksysb command to take the mksysb-image issue the mkszfile first. This command (re-)writes a file named /image.data where the sizes of all PVs, LVs, etc. in the rootvg are stated.

It is possible to edit this file and then use the edited one, this way i.e. taking a mksysb of a mirrored rootvg and restore it without mirroring onto a single disk. Without any other hints i'd start investigating this frst to find out what the culprit is. The /image.data is quite straightforward and although its content is not exactly well-documented you can understand it with some limited guesswork. Reading the man pages for mksysb and mkszfile will sure help too.

I hope this helps.

       -C config-file
	      Read configuration options from config-file.

       -l     List the expunged messages in the specified mailbox which are available for restoration.

       -t time-interval
	      Unexpunge messages which were expunged in the last time-interval seconds.  (modifiers: m: minutes, h: hours, d: days, w: weeks).

       -a     Restore all of the expunged messages in the specified mailbox.

       -u     Restore only those messages having the specified UIDs in the specified mailbox.

       -d     Unset the Deleted flag on any restored messages.

       -v     Enable verbose output/logging.
