Kona LH problems, any advice?

[Rick Sebeck]

It sounds like its your Xserve. I had a similar problem with one of the machines that was connected to our Xserve RAID. It would capture fine the fist 10-15 seconds then it would crash. It tuned out to be the write abilities to the Xserve. Two things cured it. One was an upgrade to the SAN software and OS. We use Command Soft’s Fibre Jet. It seems that all the computers connected to thee SAN should be running the same SAN software and OS. Seems logical.

The second, and to be honest I don’t REALLY remember how I got into it… but there was a setting for the RAID’s cache. Basically the raid starts sucking in info (especially while digitizing) and begins caching that info. Well the info keeps coming in and the RAID starts freaking out… thus dropping frames. I think these setting were in the RAID admin settings. Sorry I don’t have the details.. but I hope this heads you in the right direction.

Have you had problems digitizing to this RAID? does the same thing happen if you digitize to a local disc?

Thanks Rick. I have someone looking into the items you suggested.

I haven’t tried digitizing to a local disk. I will do so tomorrow to see if I have a similar problem

very valid point Rick,

first set your scratch disk to your internal hd , if it works ok then
you know it has to be a raid Issue.

Check on the Apple support web site there is an update for the xserve raid
designed for video capture:

see if it helps, check your fibre channel card’s drivers too.
