Adding asyncdsk driver to kernel

MikeL_4 — Wed, 07 Feb 2007 13:04:53 GMT

We are running Veritas Foundation Suite and have been requested by DBA's to add Veritas Database Edition for Oracle so they can implement Quick I/O for there databases.

This will require that I add the asyncdsk driver to our kernel, which is no problem, but is there anything additional that needs to be done for this ?

I've seen threads in Google that reference having to do a mknod for /dev/async and /dev/asyncdsk ??

Shalom,

HP-UX doesn't work that way. There are afew kernel parameters that refer to i/o but the OS is ready for asynchronous i/o from install time.

Assuming you would be so kind as to share with us which HP-UX release you intend to use.

sam
kernel configuration
drivers

You may see what you need.

We are running HPUX 11.11, when we tested the install of Database Edition for Oracle on a Lab server it told us we needed to add asyncdsk driver to our kernel.

Thanks, found the answer elseware, after rebuilding and rebooting server for asyncdsk drive, need to run insf -e to create the device special files:
Must have in your /dev
crw-rw-rw- 1 bin bin 101 0x000000 Jan 23 12:41 /dev/async
crw-rw-rw- 1 bin bin 101 0x000000 Jan 23 12:41 /dev/asyncdsk
