next in thread | raw e-mail | index | archive | help
I am trying to get FreeBSD to probe for multiple luns on a aic7880
controller on a Dell PowerEdge 4100 server connected to a CMD Daytona
RAIDarray (SCSI ID 0), but it only ever finds the 2G partition on lun 0,
and can't find the 10G partition on lun1. FreeBSD seems to ignore
the fact that lun 1 exists.
When I boot the machine, the controller bios correctly reports the
existance of lun 0 and lun 1. (I have multiple lun support turned on)
I remapped the 10G partition as lun 0, and the 2G partition as lun 1,
and it finds the 10G partition successfully but doesn't pick up the
2G partition.
I compiled a kernel where I specifically stated that there was something
on lun 1, but that didn't seem to help.
I turned on SCSIDEBUG; here are the bootup messages:
