In this system configuration, the disk vmhba0:0:2 has a “fixed” policy. There are six
paths to the disk recognized by ESX Server. The list of paths indicates the different
physical routes by which the disk can be accessed.
The status of each path to the disk is indicated in the second column. The report lists
each path as on, off, or dead:
• on indicates that the path is functional, and that data is being transferred
successfully
• off indicates that this path has been deliberately turned off
• dead indicates that the path should be active, but the software cannot connect
to the disk through this path
The report lists the mode of each path in the third column:
• preferred identifies the primary path ESX Server uses to access the disk
• active identifies the actual path used by ESX Server to access the disk
Note: Reports returned by vmkmultipath list paths to both physical disks and
storage controllers. In the example above, the “disks” listed as having no space
available are actually storage processors.
You can display the multipathing status for a single disk by specifying it in the query
command. For example, to display the report for disk vmhba0:0:6, enter:
# vmkmultipath -q vmhba0:0:6
