A query on Disk naming conventions in Solaris.
These are findings by me with my little experience with Solaris 10. Please correct me if wrong..
In x86 systems with ide hard disk:
c= controller
d=disk
s=slice
1.Here controller c0 means the primary ide controller ide0.
controller c1 means the secondary ide controller ide1.
controller c2 means the external drives such as usb drive.
3.c0d0 = disk connected as primary master.
c0d1=disk connected as primary slave.
c1d0= disk connected as secondary slave.
c1 d1= disk connected as secondary slave.
4.s means the slices (partitions) we create in d0, d1, d2, or d3.
For eg. the primary master hard disk's 5 th slice will be:
c0d0s5
the secondary slave hard disk's 6th slice will be:
c1d1s6
Usually, in x86, the target number is not specified. I dont see an entry in /dev/dsk directory...( is it not?) . Not sure about this. Please clarify.
5.If you connect an external usb drive, it will be treated as:
c2t0d0p0. Am i correct?
