Displaying Multipaths to a VM Disk
The vxdisk command is used to display the multipathing information for
a particular metadevice. The metadevice is a device representation of a
particular physical disk having multiple physical paths from the I/O
controller of the system. In VxVM, all the physical disks in the system
are represented as metadevices with one or more physical paths.
To view multipathing information for a particular metadevice, use the
following command:
# vxdisk list devicename
For example, to view multipathing information for c1t0d3, use the
following command:
# vxdisk list c1t0d3
Typical output is as follows:
Device: c1t0d3
devicetag: c1t0d3
