Disk device naming in VxVM

Prior to VxVM 3.2, all disks were named according to the c#t#d# naming format used by the operating system. Fabric mode disks were not supported by VxVM.

From VxVM 3.2 onward, the following methods for naming disk devices exist:

OS-based naming

In the OS-based naming scheme, all disk devices except fabric mode disks are named using the c#t#d# format.

The syntax of a device name is c#t#d#, where c# represents a controller on a host bus adapter, t# is the target controller ID, and d# identifies a disk on the target controller.

Fabric mode disk devices are named as follows:

Enclosure-based naming

Enclosure-based naming operates as follows:

See "Changing the disk-naming scheme" on page 93.

To display the native OS device names of a VM disk (such as mydg01), use the following command:

# vxdisk path | egrep diskname
