MPIO Failed Paths Disappear

-

hi,

i testing new storage server on our san , having trouble mpio.  the storage server running comstar targeting software, luns being presented on fc.  after configuring mpio claim devices present server 2012 server, can see disks appropriate number of paths in round-robin active/active mode.  

the problem seeing--well, not sure unexpected--is when remove path disks, path removed mpio device.  if remove paths, disk disappears.  the failed paths not come pack until restart (initiator/server 2012) server.    

i think record of path persist in "failed" state until retry successful, in case path brought online.  

is there wrong mpio configuration?  or harware/storage server-side problem (details below)?  comstar, far can find, not have dsm.  

storage server:
- openindiana (current version)
- qlogic hbas on server/target
- emulex hbas on client/initiator
- hp brocade fc switches
- comstar targeting software 

my mpio settings (updated original posting):

pathverificationstate     : enabled
pathverificationperiod    : 5
pdoremoveperiod           : 1500
retrycount                : 300
retryinterval             : 5
usecustompathrecoverytime : disabled
custompathrecoverytime    : 40
disktimeoutvalue          : 60

thanks!

2. if use same hardware on windows server 2008 r2, same issue occur?

3. hardware compatible windows server 2012 , latest?
