To view multi-pathing information for a particular metadevice
1
Use the following command:
# vxdisk list devicename
For example, to view multi-pathing information for c1t0d3, use the following
command:
# vxdisk list c1t0d3
The output from the vxdisk list command displays the multi-pathing
information, as shown in the following example:
Device: c1t0d3
devicetag: c1t0d3
type: simple
hostid: system01
.
.
.
Multipathing information:
numpaths: 2
c1t0d3 state=enabled type=secondary
c4t1d3 state=disabled type=primary
The numpaths line shows that there are 2 paths to the device. The next two
lines in the "Multipathing information" section show that one path is active
(state=enabled) and that the other path 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.
