Need to remove (LP)PP

UNIX AIX
1

Had increased FS system size (sample_lv) on particular disks hdisk189 hdisk190 in a shared FS

but unfortunately given addnl size occupies the space on other disks hdisk78 hdisk40 too

In case, need to remove the addnl lv size occupied on hdisk78 hdisk40. How to achieve it. Pls advice.

lslv -m sample_lv|tail
1191  0121 hdisk78           0799 hdisk132
1192  0122 hdisk78           0298 hdisk40

are the following:

hdisk132
hdisk40
hdisk189 
hdisk190

on the same VG?

to be honest i'm not entirely sure about your question

Yes, all the disks are in same VG

to increase or decrease you can use:

smit
or
chfs

i would suggest you use the man page of chfs before you use the command.

you would use:

chfs -a size=<size> G/M <filesystem
example:
chfs -a size=4G /home

That would change /home to 4G

or use like this:

chfs -a size=+4G /home

this would add 4G to /home.
