Please see notes below. Also understand that we have seen SCSI timeout
problems with this configuration under Linux when trying to qualify this
configuration with some commercial HA products. We were never able to
qualify whether or not it was a hardware problem or a problem with the
kernel they were using. Please proceed with extreme caution before
putting something like this in production.

This would be more likely to work correctly.

This would be less likely to work correctly.
