DISK SLICE NAMING CONVENTION: An 8 character string typically represents the fully name of aslice (c# t# d# s#)
1)controller:identifieshost bus adapater(HBA) which controls communication between the system and disk unit
2)targernumber:corresponding to a unquie hardware address that is assigned to each disk tape or cdrom
3)disk number: also know as logical unit number (LUN) this number reflects the number of disks as the target number 4)slice number: a slice number range from 0-7
the disk label is the ares set aside for storing information about the disk controller geometry and slices another term used to describe a disk label is the volume table of contents(VTOC)
the label dsik means to write slice information on the disk
In the bookish way c#t#d#s# is c controller t target d disk s slice
Now to make more clarity I would like to help you with an example but this is not accurate its just for your vizualisation ease. Basically c#t#d#s# is nothing but the the way of identifying a hard disk in a Solaris system
Visualize this like: With reference to your daily Intel based desktop
If you attach a new hard disk a Controller could be thought as the IDE port or your Intel motherboard like we have IDE 1 and IDE 2 The target cud be thought of like master and slave as in Intel desktop motherboard each IDE can support upto 2 jacks. and the Disk is the identification of the disk on the controller this is difficult to imagine as in our normal home desktop only one HDD can be plugged in the jack of master and slave but in sun box there can be more than one disk on the target then is the slice which is nothing but a partition on the above mentioned disk which can vary from 0-7.
Hope this example provides some clarity although this is just for mental reference Cheer
