Re: I can't bring up the KAIO on IDS 7.30 under SCO Open Server.

I think the SCO AIO Driver and suds was installed. In resume: 1. the suds checked in /etc/conf/sdevice.d/suds. I edited the file and changed the N with Y. 2. I installed the SCO AIO Driver using mkdiv aio, after I tried it with aioinfo. ( I guess aio is right ) 3. I Modified the AIO Kernel parameter. 4. I relinked the kernel. 5. I setted the KAIOON=1, I tried to start the online server. Whatever, I am not sure suds drivers was installed, how can I test it? and I read about suds_ctrl and aiomemlock, but I have a doubt if I've got to use suds_ctrl or aiomemlock. did I have to use? and how?
