MSA 1000 Acive to Standby

[ZK_1]

Recently we purchased one MSA 1000 With 2/8 Switch , all redundant ,4 BL 460 C ,one DL 360 G5 (only one single port HBA) and one MSL2024 LTO-3 Ultrium 960 Tape Library (one port connected to Switch )

Problem what we are facing is sometimes the controller will Move Active to standby , since we have Dl 360 and MSL 2024 having only one port connected to switch we are losing connectivity

all blade C 460 Servers are installed with Windows 2003 server and MPIO version v1.40

Controller Firmware Version is 4.48.B342

any recommendations
