[Litsov]

Good day All.
I have EVA 3000 4100 firm. with 2 Windows host. 4/16 sw(6.1 fw).
suddenly all Luns from hosts disappear. The host see EVA devices(controllers) in device manager, but no LUNs in Disk manager. I've tryed to unmap and map again LUNS to hosts. But nothing happend.
The Qlogic sansurfer see only zero system lun from EVA. I have reboot all hosts, EVA, Switches,
resolve some problems with SFPs, nothing changed.
Need help.
