Hi

It looks like you have a paging space on a disk being used by oracle (my assumption) in addition to your rootvg (OS) paging space.  Provided the activity on this disk is not 'heavy' this should be OK. If this were a disk with heavy I/O this would probably impact performance.

Why are these different? (I'll assume too that you know they are considerably different in size)  My guess is that the difference in the size of paging space is why the utilisation is so.

My belief is that AIX prefers to see paging spaces of equal size to allow an even distrbution of usage (round robin); this would then suggest that because this is not the case here that your hd6 is being utilised more than the paging00, hence the differences.

Cheers, JP.

Undernormal conditions AIX when equipped with chipkill RAM will mirror RAM to swap and pull back if RAM fails.

Growing of PagingSpace is kinda normal. You should monitor your PagingSapce for some days and have a look if it's constantly growing or sometimes also shrinking.
