Solution Type  Problem Resolution Sure

Solution  1005730.1 :   Sun Enterprise Volume Manager[TM] 2.X does not show both paths in DMP as valid after replacing GBIC hardware.  


PreviouslyPublishedAs

Symptoms
When a GBIC is replaced in an Sun StorEdge[TM] A5x00 array (photon),
Sun Enterprise Volume Manager (SEVM, Veritas Volume Manager, VxVM)
will not always recognize that the loop has been healed, and
therefore will not enable the previously failed path in
Dynamic MultiPathing (DMP). This is most likely to occur in
Sun Enterprise Volume Manager (SEVM) versions 2.x.

Resolution

You can verify whether the path has been
re-enabled or not by typing:
vxdisk list <diskname>
and looking for the section of the output that looks like:
Multipathing information:
numpaths:   2
c1t2d0s2        state=enabled
c2t2d0s2        state=disabled
If one of the paths still shows as disabled after the GBIC has been replaced,
perform one of the following:
vxdctl enable
or from vxva Volume Manager GUI in the 2.x versions:
Disks -> Advanced Ops -> DMP -> Reconfigure DMP
This should cause Volume Manager to recognize that the path has been restored.
