Тут краткая заметка по поводу томов, и как с ними работать. В основном ключевые места из документации.
Disk Devices
- Volume Manager supports up to sixteen partitions
- partitions also called slices
A partition is addressed through a physical address (generally referred to as the device name) of the form c#b#t#d#s#, which is comprised of the following elements:
* c# --The number of the controller to which the disk drive is attached. * b#--The corresponding bus. * t# and d# --The target ID and device number that constitute the address of the disk drive on the controller. * s# --The partition number on the disk drive.
An example of a device name is c0b0t0d0s0. By convention, s0 is used to refer to the standard partitioning method used by VxVM. The physical disk is identified to the Volume Manager as c#b#t#d#s#. For many commands, the suffix s# is normally optional, though display commands usually report devices with an s# suffix. The Volume Manager vxdiskadm and vxdiskadd utilities take device names without the s0 suffix. For example, to specify the second disk attached to the first controller to vxdiskadd, use the name c0b0t1d0.
