We mapped two LUNs to the host, and could view two virtual LUNs and four physical LUNs on the UltraPath management interface.
We powered off and on the iSCSI interface module on controller A twice.
Then on the UltraPath management interface, we saw only one virtual LUN instead of two.
In Computer Management > Device Manager shown in Figure1, we also saw four physical LUNs and only one virtual LUN.
