Default How to distinguish active and standby path?

Hi Christophe,

* We're using your multipath tools to access an Active-Standby storage(Oracle SS7420 if you're concerned.)

* There're 4 path's to a LUN, 2 active and 2 standby.
* But we can't distinguish them from 'multipath -ll'.


* for example:
-------------------------------------------------------------------------
chuli3v0 (3600144f0ad85965d00004f446c610001) dm-34 SUN,ZFS Storage 7420
[size=4.0T][features=0][hwhandler=0][rw]
\_ round-robin 0 [prio=1][enabled]

*\_ 8:0:2:2* sdbd 67:112* [active][ready]
\_ round-robin 0 [prio=1][enabled]
*\_ 6:0:3:2* sdt* 65:48** [active][ready]
\_ round-robin 0 [prio=1][enabled]
*\_ 8:0:0:2* sdbv 68:144* [active][ready]
\_ round-robin 0 [prio=1][enabled]

*\_ 6:0:2:2* sdcn 69:176* [active][ready]
-----------------------------------------------------------------------

* All 4 path's are same.
* We're using redhat 5.5 and multipath 0.4.7

* Is there any way to distinguish them?


* Thanks and regards

Sam
