mklv -ae -tboot -yhd5 rootvg 2 <disk_name>
where <disk_name> is an optional argument that should be used if your
rootvg has more than 1 physical disk. After recreating it, you should
use "lslv -m hd5" to verify that the partitions are contiguous.
It is a bit more complicated for AIX v3, but I'm assuming that you're
using v4.

bosboot -a
else you have an empty filesystem and your box
will never boot again.

Then,
bosboot -ad/dev/ipldevice
and have a long cool one as bosboot cranks along for 3-4 minutes.
When it completes, you are golden.
ps, if you want you can create a file "/tmp/bozo" which looks like
0001 hdisk0
0002 hdisk0
(above assumes hdisk0 is your ipldevice)
and use smit to create hd5 and point to /tmp/bozo as the 'map file'
on the smit dialog screen.

You lucky so & so. There are a lot of LV's a lot more critical than hd5
it simply contains the boot info and can be easily recreated as detailed
in other replys, or do you think hd5 is a disk, like hdisk5. Again, hd5
is a small, one or two PP LV without a filesystem on it called the BLV
the Boot Logical Volume. It gets destroyed & recreated on the fly all
the time, when bosboot is run, software upgrades etc. As I said you were
lucky.
