sys/scsi : mpath.c mpath_rdac.c mpath_sym.c mpathvar.h
Log message:
implement handling of group failover.
if a controller sends sense data back, the path driver can tell
mpath that its indicating failover which kicks off an iteration
over all the groups until one says its active. if no groups claim
to be active, a timeout fires the process off again after a second.
you can start controller handover on rdac (well, an md3200i is all
i had to test with, others might need more work) and everything
keeps going. ill try to get to emc and hds working when i can poke
hardware again.
