Multipathing information:
numpaths: 2
c1t0d3 state=enabled type=secondary
c4t1d3 state=disabled type=primary
In the Multipathing information section of this output, the numpaths line
shows that there are 2 paths to the device, and the following two lines show that
the path to
c1t0d3 is active (state=enabled) and that the other path c4t1d3
has failed (state=disabled).
The type field is shown for disks on Active/Passive type disk arrays such as the
EMC CLARiiON, Hitachi HDS 9200 and 9500, Sun StorEdge 6xxx, and Sun
StorEdge T3 array. This field indicates the primary and secondary paths to the
disk.
The type field is not displayed for disks on Active/Active type disk arrays such
as the EMC Symmetrix, Hitachi HDS 99xx and Sun StorEdge 99xx Series, and
IBM ESS Series. Such arrays have no concept of primary and secondary paths.
