Disk roaming has some constraints as described in the followings:
1.
Check the firmware of two systems first. It is better that both systems have the same
firmware version or newer.
2.
All physical disks of related RG should be moved from system-1 to system-2 together. The
configuration of both RG and VD will be kept but LUN configuration will be cleared in order
to avoid conflict with system-2.

Support Microsoft MPIO and MC/S
MPIO (Multi-Path Input/Output) and MC/S (Multiple Connections per Session) use multiple physical paths
to create logical "paths" between the server and the storage device. In the case which one or more of
these components fails, causing the path to fail, multi-path logic uses an alternate path for I/O. So
applications can still access their data.
Microsoft iSCSI initiator supports multi-path. Please follow the procedures to use MPIO feature.
1.
A host with dual LAN ports connects cables to controller.
2.
Create a RG/VD and attach this VD to the host.
3.
When installing “Microsoft iSCSI initiator”, please install MPIO driver at the same time.
4.
Logon to target separately on each port. When logon to target, check “Enable multi-path”.
5.
MPIO mode can be selected on Targets
