As firefox111 stated run;

Code:

lsvg -l rootvg

This will display something like;

Code:

root@ap1:/u/amilburn $ lsvg -l rootvg
rootvg:
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
hd5                 boot       1     2     2    closed/syncd  N/A
hd6                 paging     16    32    2    open/syncd    N/A
hd8                 jfslog     1     2     2    open/syncd    N/A
hd4                 jfs        1     2     2    open/syncd    /
hd2                 jfs        7     14    2    open/syncd    /usr
hd9var              jfs        2     4     2    open/syncd    /var
hd7                 sysdump    5     5     1    open/syncd    N/A

As you have probably already figured out you are looking for the number of LPs compared to the number of PPs. if the PPs are doubled then it is mirrored. If it is not then figure out where that LV resides. If it already resides on hdisk1 then it will not do you any good but if it resides on hdisk0 then you can use;

Code:

migratepv -l logicalvolume hdisk0 hdisk1

to move that LV from hdisk0 to hdisk1 to free up some space on hdisk0.

You can use

Code:

lspv -l hdisk?

to figure out which disk the LV in question resides.

In my case my the only LVs that are not mirrored are my sysdump devices so that might be something to look for.
