mirror rootvg

Hello

I have a new problem with mirror rootvg

I need to do the same thing on others servers. In one of these I do the same with no problem, but in another fs on the same server I got this message

lsvg -l rootvg
rootvg:

There are not enough free partitions or not enough physical volumes

should be retried with different allocation characteristics.

Thanks again for your tips.

Sorry, lo-lp-kl, but this really takes the biscuit: what is ununderstandable in an error message which lists the reason of why and how a command failed with painful clearness?

You have a (one or more) mirrored LV, which properties perhaps say "each copy on a separate disk" (which makes sense, because two copies of one LP on the same disk would both be lost once the disk fails) and one of these disks does not have enough free PPs to increase the LV in size. Install an additional disk (or instead change the disk for a bigger one), add it to the VG (see "man extendvg"), and try again.

On a personal note: PLEASE read a bit about the Logical Volume Manager and try to understand its concepts. Everybody, regardless of knowledge or experience, is welcome here and indeed we are gladly trying to accomodate even the most "newbiest" of newbies but asking the equivalent of "what does 'disk full' mean" is supposedly slightly overdoing it.

I hope this helps.

mirror rootvg

Thanks for the comments bakunin

I agree with you but sometimes we have to do somethings in the fly and dont have to much time to read the books.

I resolve the problem with the mklvcopy. I need to type the command with the hdisk0 because the fs was created on the hdisk1.

The mirror was created but when I try to syncvg -v rootvg nothing happens

I got this

LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
hd5 boot 1 2 2 closed/syncd N/A
hd6 paging 24 48 2 open/syncd N/A
hd8 jfs2log 1 2 2 open/syncd N/A
hd4 jfs2 16 32 2 open/syncd /
hd2 jfs2 77 154 2 open/syncd /usr
hd9var jfs2 12 24 2 open/syncd /var
hd3 jfs2 12 24 2 open/syncd /tmp
hd1 jfs2 12 24 2 open/syncd /home
hd10opt jfs2 12 24 2 open/syncd /opt
lg_dumplv sysdump 16 16 1 open/syncd N/A
Websphere jfs2 80 160 2 open/stale /opt/IBM
paging00 paging 24 48 2 open/syncd N/A

I try also with syncvg -l Websphere and also with varyonvg rootvg but the same thing nothing happens.
