vgcreate problems
# vgcreate vgu23 /dev/dsk/c14t3d1
Increased the number of physical extents per physical volume to 51199.
vgcreate: Volume group "/dev/vgu23" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the
extent size or decrease max_PVs/max_LVs and try again.

Re: vgcreate problems
You may need to increase the PE size while creating VG. By default PE size is 4MB.
# vgcreate -s <4/8/16/32/64>
Thanks & Regards

Re: vgcreate problems
You can see, these defaults are too large.
Consider to reduce at least one of them or increase the PE size.
see
http://docs.hp.com/en/B2355-60105/vgcreate.1M.html
If you tell us the output of
diskinfo -v /dev/rdsk/c14t3d1
this will give us more info about the disk size - easier to suggest something.
Hope this helps!
Regards
Torsten.

Re: vgcreate problems
If know about them you will understand the problem.
See also
http://docs.hp.com/en/B2355-90950/ch06s01.html#bficdcif
The first physical extends (PE) will hold VG specific data - no user data.
This includes information about the extend and LVOL layout etc. LVM will calculate and reserve space for future added disks too.
This special area (VGRA) is limited to 1 PE.
If the disk is large and the maximum of disks for this VG is large too, 1 PE is just too small to hold all information.
This is the reason of the error you get.
If you specify now a larger size of the PE's, you (your system) will get more space to save this information.
So you should specify the "new" PE size in your command:
# vgcreate -s 8 vgu23 /dev/dsk/c14t3d1
Hope this helps!
Regards
Torsten.
