Hi all I wonder if anyone has a working setup with a HDS device. Right now I am seeing a weird performance issue. With default multipath settings dd of zeros into the /dev/mapper lun shows at 0.2kbps while writing directly into a single path at /dev/sdb provides 900Mbps. I am using 10g iscsi with 4 ports on the HDS and dual port cnas on the hosts Thanks Dan
