IMHO it would use what it has so 7.1...
You do have a mksysb somewhere I hope? Thats would be the best deal to put all at the level of that image... then you could start all again... When you say it renamed all the LV are you talking of rootvg only ? because those have just numbers to what I remember so I dont see how you could see anything change, but if the others that is because of their definition you find in /etc/filesystems which is found on rootvg, in other words using a mksysb from a previous configuration may show trouble mounting disks if not the same or for unfound filesystem and will not mount what it doeesnt know of like new LVs etc...
The same is true for passwords, reason why I include root passwd somewhere with it, I did before that make mksysb removing root passwd but found it was a terrible threat as too many engineers around, one could do silly things by mistake...
I have learned maybe the hard way, but I did too because of an HACMP failure long ago, that when anything system has changed like adding removing disks, new net or HBA cards etc... to update a text file YOU manage with vi and nothing else, somewhere you can always find if the system can boot (single user or maintenance level) where you can see what you know of and compare in order to get things right and not drown into more trouble such as the system seeing "new disks" will quite surely scan and find LVs and so ...
AIX is like HP-UX very robust, both have their pros and cons, but both have first class system administration tools which explains they are still on the market, one strength is that very very rarely you need to re-install after a serious issue on the hundred I had to administrate I never had once to reinstall a box except and AIX 4.3 as I never found out what a previous sysadm did to wreck the box , I had to format the root/boot disk twice to get it looking sane again but we are talking pre Y2K ...

quotacheck
QUOTACHECK(8) BSD System Manager's Manual QUOTACHECK(8)
NAME
quotacheck -- filesystem quota consistency checker
SYNOPSIS
quotacheck [-gquv] filesystem ...
quotacheck [-gquv] [-l maxparallel] -a
DESCRIPTION
quotacheck examines each filesystem, builds a table of current disk usage, and compares this table against that recorded in the disk quota
file for the filesystem. If any inconsistencies are detected, both the quota file and the current system copy of the incorrect quotas are
updated (the latter only occurs if an active filesystem is checked). By default both user and group quotas are checked.
Available options:
-a If the -a flag is supplied in place of any filesystem names, quotacheck will check all the filesystems indicated in /etc/fstab to be
read-write with disk quotas. By default only the types of quotas listed in /etc/fstab are checked. See also -l.
-g Only group quotas listed in /etc/fstab are to be checked. See also -u.
-l maxparallel
Limit the number of parallel checks to the number specified in the following argument. By default, the limit is the number of disks,
running one process per disk. If a smaller limit is given, the disks are checked round-robin, one file system at a time. This
option is only valid with -a.
-q quotacheck runs more quickly, particularly on systems with sparse user id usage, but fails to correct quotas for users [groups] not
in the system user [group] database, and owning no files on the filesystem, if the quota file incorrectly believes that they do.
-u Only user quotas listed in /etc/fstab are to be checked. See also -g.
-v quotacheck is more verbose, and reports corrected discrepancies between the calculated and recorded disk quotas.
Specifying both -g and -u is equivalent to the default. Parallel passes are run on the filesystems required, using the pass numbers in
/etc/fstab in an identical fashion to fsck(8).
Normally quotacheck operates silently.
quotacheck expects each filesystem to be checked to have a quota files named quota.user and quota.group which are located at the root of the
associated file system. These defaults may be overridden in /etc/fstab. If a file is not present, quotacheck will create it.
quotacheck is normally run at boot time from the /etc/rc file, see rc(8), before enabling disk quotas with quotaon(8).
quotacheck accesses the raw device in calculating the actual disk usage for each user. Thus, the filesystems checked should be quiescent
while quotacheck is running.
If quotacheck receives a SIGINFO signal (see the status argument for stty(1)), a line will be written to the standard error output indicating
the name of the device currently being checked and progress information.
FILES
quota.user at the filesystem root with user quotas
quota.group at the filesystem root with group quotas
