Problem(Abstract)
KAIO is not enabled when chunks are created on raw devices. OS and related environment are no problems.
Cause
ls -l shows that the chunks are in the raw devices which are created as block devices by mistake.
ls -l
brw-rw---- 1 root system 22, 1 Aug 4 2012 rootchk
brw-rw---- 1 root system 22, 1 Aug 4 2012 llogchk
brw-rw---- 1 root system 22, 1 Aug 4 2012 plogchk
brw-rw---- 1 root system 22, 1 Aug 4 2012 datachk
The raw devices should be character devices.
crw-rw---- 1 root system 22, 1 Aug 4 2012 rootchk
crw-rw---- 1 root system 22, 1 Aug 4 2012 llogchk
crw-rw---- 1 root system 22, 1 Aug 4 2012 plogchk
crw-rw---- 1 root system 22, 1 Aug 4 2012 datachk
Resolving the problem
Change the devices to character devices with relative OS commands and restart Informix Server. Then KAIO will be enabled correctly.
