I have question about two SCSI controllers on one SCSI bus,
I want to run following configuration: one FreeBSD with SCSI controler,
with mounted disks in read/write mode, and another FreeBSD with SCSI
controller on the same bus with mounted disks in read-only mode.
So can two controllers correctly handle SCSI bus with FreeBSD drivers ?
(I mean aic78* controllers)
I don't expect this to work because the readonly side can't know when the
incore informations outdates.
Yes, it can be a problem, but may be this may be solved by disabling any
cache on read-only side (or setting expire time in one sec) ?
The two controller side shouldn't be the problem - but I can't say for shure
as I don't know the CAM system much and havn't tried.
