Paging Space on mirrored 2 disk volume group

[jrmartin]

Scenario:
Mirrored volume group with two physical drives and two paging spaces.

Even though the primary copies of each paging space are on separate disk, doesn't this set up still violate the rule of not having two paging spaces share a physical volume?

I think the person who set this up was thinking they would have two spindles for paging, which would improve performance.

In this situation because of the mirroring wouldn't it be better to have one larger space mirrored to the other disk?

Example
lslv -m paging02|pg
paging02:N/A
LP PP1 PV1 PP2 PV2 PP3 PV3
0001 0055 hdisk6 0048 hdisk7
0002 0056 hdisk6 0049 hdisk7

lslv -m paging00|pg
paging00:N/A
LP PP1 PV1 PP2 PV2 PP3 PV3
0001 0080 hdisk7 0023 hdisk6
0002 0081 hdisk7 0024 hdisk6

Yup, but different paging spaces are easier to manage than a big paging space, because AIX can't reduce the size of any logical volume. I eventually I need less paging space I can deactivae one pagin space and don´t need to try complex procedures to reduce un-reduceable volumes!

I hope it works...
Unix was made by and for smart people.

Hello,
depending on how much paging is used you can remove the mirroring of 1 of the paging space.
