[Linux-cluster] GFS/SCSI Lost

[isplist at logicore.net]

I posted about this last night but found some additional info. My first post 
was not very useful, showing a paste of SCSI errors after it was disconnected.

I see that something just times out and the storage is lost. I find that I can 
just get on the node, unmount the lost mount, remount and it's back. I also 
notice that the mount is set as non permanent? 

Do I need a keep alive script or is there a configuration somewhere I've 
missed? Here is a snippet from where SCSCI errors started overnight.
