used PPs not match the total disk space showed by df

Hi,

I see from lsvg the total used PPs is 1050 (67200 megabytes), but when I check the disk space with df command I can only see 31G total space, can somebody tell how this come?

Thanks!
Victor

Better do a

lsvg -l rootvg

and check again if the number of used PP is not correct. Chances are, that you have rootvg mirrored and so 2 PP (each on a different hdisk hopefully) belong to one LP. Space calculation for mounted FS'es with df belong to LPs, not to PPs.
Also you will have some LVs of the type boot, paging, jfs2log and sysdump, which don't show up in df either.

Hi Zaxxon,

You are correct, we are rootvg mirrored .

Thanks!
