[smartmontools-support] access with linux to drives visible on scsi bus, but not as dev nodes.

[Elliott A. J. <el...@ip...>]

I've been using mpt-status on a herd of Dell machines running linux, but would prefer what smartmontools offers on our HP machines with CCISS arrays.

It appears that the fusionMPT drivers conceals the physical devices behind the hba, but the drives are S.M.A.R.T. capable and visible on the scsi bus:

Can smartmontools access a device via the scsi bus or does it require that a device node exist for the drive?  Are there any work arounds to allow smartmontools to access these disks?

Thanks in advance,
