Ok with the AIX5.3ML11 (> ML8 is were you need to be)
you have 36096 megabytes (36GB) free in the vg to allocate without requiring the need to more disk.
you said you needed approximate 36GB to add so you are going to add it and it will go to these disk drives.

hdisk64 active 199 70 00..00..00..30..40
hdisk65 active 199 71 00..00..00..31..40
hdisk66 active 199 70 00..00..00..30..40
hdisk67 active 199 71 00..00..00..31..40

Since this is SAN disk I will assume that all the raid is handled by the back end. and you are not doing mirroring

with all that said we are going to let AIX find and place the required PP's as needed. But I do have 1 more question.
Why are the disk drives we are going to use only 199 PP's but all the others are 399 PP's.
The SAN should have allocated the same disk size to you for usage.
SO is this correct disk for the system?

Anyway you can do this in smit or

Code:

chfs -a size=+9G /sapdata5qa  (I am also assuming that this is the File System Mount and not the LV)

I would probably just round the 7.75 and the 7.50 GB's to 8.
But if you want the exact you will do the GB size the another for Meg size.

And like all things be sure you have a valid backup before you do this.

apmlabel

APMLABEL(8)						    BSD System Manager's Manual 					       APMLABEL(8)

NAME

     apmlabel -- update disk label from Apple Partition Map

SYNOPSIS

     apmlabel [-fqrw] device

DESCRIPTION

     apmlabel is used to update a NetBSD disk label from the Apple Partition Map found on disks that were previously used on Mac OS systems (or
     other APM using systems).

     apmlabel scans the APM contained in the first blocks of the disk and generates additional partition entries for the disk from the entries
     found.  Driver and patches partitions are ignored.

     Each APM entry which does not have an equivalent partition in the disk label (equivalent in having the same size and offset) is added to the
     first free partition slot in the disk label.  A free partition slot is defined as one with an fstype of 'unused' and a size of zero ('0').
     If there are not enough free slots in the disk label, a warning will be issued.

     The raw partition (typically partition c, but d on i386 and some other platforms) is left alone during this process.

     By default, the proposed changed disk label will be displayed and no disk label update will occur.

     Available options:

     -f  Force an update, even if there has been no change.

     -q  Performs operations in a quiet fashion.

     -r  In conjunction with -w, also update the on-disk label.

     -w  Update the in-core label if it has been changed.

HISTORY

     The apmlabel command appeared in NetBSD 5.0.
