Changing the region will not give you more space, so most likely your problem will not change at all.

You can move the PPs used by a LV with the "migratepv" command. See the man page for details.

I hope this helps.

The command lspv hdiskX will tell you how much free space is available on a volume. Look for FREE PP.

If that is 0 (or otherwise less than you want to grow a filesystem) you need to add a volume, or use
# chfs -a size=-XXXM /somefs_in_vg to free space from where too much has been given!

Hope this helps you further.

migratepv and/or chlv to change region assignment, followed by reorgvg (read man pages) will help minimize potential performance issues from fragmented logical partitions.

see this i can unmirror rootvg but i can not reduce it from the rootvg

PHP Code:
/tmp>lspv | grep rootvg
hdisk0 00c759904bc3798c rootvg active
hdisk1 00c759904bc379e1 rootvg active
/tmp>unmirrorvg rootvg
/tmp>reducevg -d rootvg hdisk1
0516-1782 reducevg: Physical volume hdisk1 is not part of volume group
rootvg.
0516-884 reducevg: Unable to remove physical volume hdisk1.

First off: we have "CODE"-tags and "PHP"-tags. Please use "CODE"-tags for terminal output and data, not "PHP"-tags, because the latter are expecting PHP-code inside, which you are not posting. The button to add "CODE"-tags is labeled "CODE", the button for PHP-tags is labeled "PHP. This should make it possible to discern one from the other with finite effort. Thanks.

It might be that the information in your ODM is somehow corrupted (this happens sometime). Try to correct this by using the "synclvodm" command and "cfgmgr". You can even dump the contents of the ODM by using the "odmget" command. See the man pages of the respective commands for details.

I hope this helps.

This might help, but is not guaranteed to work. When the system restarts it runs "cfgmgr" in mode 1, which isn't possible at any other time. This might correct any inconsistencies in the ODM if this is indeed the cause - it was just a guess of mine, although the most probable reason for the behavior you describe.

If it doesn't work and the problem is indeed the ODM you might need to correct it otherwise. Take a "mksysb" backup and restore it to another - identic - system to a fresh disk, then try to boot from this disk. (You have not told us so far, but i am assuming this is an ordinary LPAR, nothing anything fancy?)

I hope this helps.
