I have a filesystem that the users want bigger. The filesystem is a
mount of the sandboxc logical volume. The LV looks like:

# lslv -l sandboxc
sandboxc:/vistaarchive

So I have a few disks with lots of free PPs. But how do I 'grow' my
existing filesystem?

With chfs. Read the manual page, note the option '-a Size=[+]<NewSize>'.
You can also user smit: 'smitty chfs'.

This will extend the file system, the required partitions are taken from
any disk in the volume group. The underlying logical volume is grown
automatically.

If you want to specify from which disks the partitions should be taken,
first extend the logical volume with extendlv and then extend the
file system on it.

Okay, I increased the "MAX LPs" for my LV. I then grew the LV and then
grew the FS all with smit (which just runs chlv, chfs, etc).
Thanks

If I have just one volume group & 1 hard disk and several logical
volumes, do I need to add PPs to the logical volume being changed in
size?

When you extend the logical volume, new PPs are allocated to it.
This happens automatically if you use extendlv.
If you want control over which PPs are allocated, you will have to create
a map file and use extendlv -m.
