1.Why not using "extendvg rootvg hdiskX" ?


2.

http://publib.boulder.ibm.com/doc_link/en_US/a_doc_lib/cmds/aixcmds1/chvg.htm

-t [factor] Changes the limit of the number of physical partitions per physical volume, specified by factor. factor should be between 1 and 16 for 32 disk volume groups and 1 and 64 for 128 disk volume groups.
If factor is not supplied, it is set to the lowest value such that the number of physical partitions of the largest disk in volume group is less than factor x 1016.

If factor is specified, the maximum number of physical partitions per physical volume for this volume group changes to factor x 1016.

Notes:
If the volume group is created in AIX 3.2/4.1.2 in violation of 1016 physical partitions per physical volume limit, this flag can be used to convert the volume group to a supported state. This will ensure proper stale/fresh marking of partitions.
factor cannot be changed if there are any stale physical partitions in the volume group.
Once volume group is converted, it cannot be imported into AIX Version 4.3 or lower versions.
This flag cannot be used if the volume group is varied on in concurrent mode.
The maximum number of physical volumes that can be included in this volume group will be reduced to (MAXPVS/factor).
Change of the volume group may require the modification of the LVM meta data. In this situation the volume group will be varied off in management mode to ensure the integrity of the Volume group, needing the closure of all open logical volumes in this volume group. Since logical volumes in rootvg cannot be closed, rootvg cannot be converted if it needs modification of the meta-data as part of the chvg -t operation.

If you plan on ever importing that vg to another machine that is running AIX 4.3.0 or lower, then don't do it. However I cannot imagine why you would ever need to import a rootvg from one server into another running system. So go ahead. But...

...why do you need to change the factor on your rootvg? Do you really have that many disks in rootvg?

all begin because i want to ad other disk to my system
extendvg rootvg hdiskX command and send me this message

extendvg rootvg hdisk1
0516-1162 extendvg: Warning, The Physical Partition Size of 32
requires the
creation of 1084 partitions for hdisk1. The limitation for volume
group
rootvg is 1016 physical partitions per physical volume. Use chvg
comman
d
with -t option to attempt to change the maximum Physical
Partitions per
Physical volume for this volume group.
0516-792 extendvg: Unable to extend volume group.


then the people of the forum tell me i have to run this command

chvg -t 2 rootvg

but this command send me this message

WARNING, once this operation is completed, volume group rootvg
cannot be imported into AIX 430 or lower versions. Continue (y/n) ?

all i wanna do its add my new disk to my actual system i dont want import this file system to another machine i just want to add my new disk to the actual file system.

the message of warning its important to me because i dont want make useless my server. runninfg this command but thaks fot the help any ideas are important to me

Hehe, I was asleep at the keyboard, got my logic backwards. Not too many disks, too many PP! Go ahead and run the chvg.
