I have heard that multipath i/o is supported on s390 and was curious how this is accomplished. If anyone has any information I'd appreciate a reference or a reply to this post.
On other architectures, multipath i/o is handled in the scsi layer, using the scsi id found on newer drives. However, on a 390 system I haven't a clue as to how multipath would be handled ... unless the dasd driver is handling it ... but I don't think it does. Can anyone shed some light on this? Thanks! -Don
