Dear AIX,
vpath is a pseudo device know from IBM multipathing SW called SDD.
So more info you can find in the SDD User's Guide available for you on
this web page. Some copy-paste sentences from there:
Each SDD vpath device represents a unique physical device on the storage server. Each physical device is presented to the operating system as an operating system disk device. There can be up to 32 operating system disk devices that represent up to 32 different paths to the same physical device. However recommendation is to use not more than 4 to 8 different paths to the same physical device. The SDD vpath devices behave almost like native operating system disk devices. You can use most disk device operations of operating systems on the SDD vpath devices, including commands such as open, close, dd, or fsck.
Have fun!
