Hi People,

This folder contains nodes which point to disk devices. It should be read as

c0t0d0s0 -> ../../devices/pci@1f,0/ide@d/dad@0,0:a,raw

pci@1f,0 - PCI bus 1f, dev 0; c0
ide@d - address of ide and port d
dad@0,0:a,raw - disk access device , t0, d0, s0

This folder contains all nodes which can point to any disk drives (SCSI,
RAID, IDE). Unused nodes are not cleared automatically by OS and if you feel
that the entries are old you can clean them out by

"devfsadm -C -v" or "reboot -- -r"

Big thanks to Michael Sullivan, Bernd Schemmer and all others who responded

Best Regards
Alexander
