Can you show us the output from the following:-
When creating a volume group, some limits are either set or assumed and it may be that you've hit one of these.

Volume group SAPVG old, not me create the volume group.
How to add new disk to volume group not error..
Anyway, thanks for the output. It gives us:-
From the manual page for mkvg, we read:-
Quote:
When creating the default volume group type (with a maximum of 32 PVs) or the big volume group type (with a maximum of 128 PVs), there is a
limitation of 1016 physical partitions per PV. When specifying the physical partition size (-s), make sure the value is set large enough so
that 1016 physical partitions per PV limit is not violated. For example, a partition size of at least 16 MB would be needed to create a volume
group with a 10 GB disk. Using a factor size (-t) of 2, a smaller partition size of 8 MB can be used. If a factor value is specified, the
maximum number of PVs that can be included in the volume group is MaxPVs/factor.
I think that you have reached this limit. Have a calculate to see if you agree. When creating the VG, the PP size has been set larger, possibly automatically for a 3Tb volume group.
Read the manual page for chvg and see if you might get away with chvg -G but read the manual first to see if it applies safely to you.
You may need to build a new volume group and add more logical volumes in there. Our main Oracle database has 12 volume groups with around 30 logical volumes in each. What do you need to add the extra disk for? There is space to grow LVs in your current VG - although it's only about about 3G which is pretty small for this VG I suppose.
