Kernel Asynchronous I/O (KAIO) is supported on this platform. However, it is DISABLED by default. To enable KAIO set the environment variable KAIOON. It is only effective on raw partitions. KAIOON=1; export KAIOON (for Bourne or Korn Shell) setenv KAIOON 1 (for C Shell) The following is a pre-requisite for using KAIO: o. HP KAIO driver "asyncdsk" is installed and linked into the kernel. o. To ensure KAIO driver is up and running, check to see if there is /dev/async, if not follow these steps: 1) su root 2) /usr/sbin/mknod /dev/async c 101 4 3) chmod 0666 /dev/async

TBP, I done the steps that you sent me (set KAIOON=1 and install asyncdsk), but the error still the same What can I do to solve this problem ?

Current State Pending State Looks a bit odd to have "KAIO disablsed".
