<DIV><SPAN class=990122118-13032009><FONT face=Arial size=2>Using Windows SRP
(WinOF_2-2030_wnet_64) / Linux SCST+SRPT (svn 695) with dynamic
disks leads to some strange behavior when the initiator is rebooted.
All basic disks come back online just fine. The dynamic disks show up multiple
times under the same names in disk manager, all as offline or unreadable. The
basic disks show as unreadable in disk management even though they are connected
and working fine. I expect to see the dynamic disks as offline since the IB and
SRP devices come up after DMIO. I can script to bring these disks online after
boot. </FONT></SPAN></DIV>

restarting the WinOF SRP Miniport Device restores my basic disk, but only one
dynamic disk comes back online (with failed redundancy). The following doesn't
look right either. Does this have to do with the MPIO from the MS iSCSI
initiator package?</FONT></SPAN></P><FONT size=1>

fine using the SCST + iSCSI target with MS iSCSI initiator. Maybe
because the iSCSI initiator timing issues put it way farther back in
the load process behind the network stack and DMIO/LDM
