v3700

Recently one of our IBM Xseries 3650 M4 server faced hardware failure related to local storage. Two partitions from IBM Storwize v3700 were assigned to this system, connected with 2 QLogic FC cards connected with 2 BROCADE fiber switches for fail over.

After doing re installation of Windows 2008 R2, SAN partitions were appearing duplicate. Windows MPIO feature was enabled but still partitions were twice appearing. After applying IBM base SDDDSM MPIO updated driver, problem got solved.

Subsystem Device Driver Device Specific Module (SDDDSM) is IBM’s multipath IO solution based on Microsoft MPIO technology, it’s a device specific module specifically designed to support IBM storage devices. Together with MPIO, it’s designed to support the multipath configuration environments in the IBM Storage.

Download link is as follosw. Just a small patch , apply and restart 🙂
