Guillaume,

You can have multiple major numbers used for DASD devices, but my point was
to avoid using DASD at all, and use straight SCSI to the storage array.

The problem is still the number of available minor numbers. If I am not
mistaken, the kernel gives 4 minor numbers for one dasd. This means you
can mount at the same time 255/4 = 63 disks. You can still play with the
kernel ignore list, I guess. Am I missing anything ?

Anyway, the 2.6.0 kernel is supposed to be released with 32 bits device
numbers.... So this should not be a problem anymore.

Guillaume.
