VIOS Paging Default Devices


When you install a VIOS (or AIX) from the installation DVD, or a NIM source created from DVDs, the default paging devices are not optimal.
It has always been a best practice for paging devices to never have more than 1 device per physical volume.

Yet the default build creates 2 un-even sized paging devices on hdisk0.

$ ioslevel

$ oem_setup_env

# lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type Chksum
paging00 hdisk0 rootvg 1024MB 1 yes yes lv 0
hd6 hdisk0 rootvg 512MB 1 yes yes lv 0

Please update the default VIOS and AIX build process to only create hd6 on hdisk0 and size it accordingly.
