Here on the OEM team, we are often asked storage-related questions about the latest versions of Storport.sys, the iSCSI Initiator, and MPIO.
For easy reference, below are the latest available versions of Storport.sys, MPIO, and the iSCSI Initiator as of 7/15/2009. Both GDR branch fixes available directly from the Microsoft Download Center and LDR branch fixes available from Microsoft Support are listed.
Please note that all updates are cumulative within the same branch, so though the below updates may not resolve a problem you are seeing, a previous fix may resolve your problem. Look for more details on GDR fixes versus LDR fixes in David's post from 3/11/08: "What is the difference between general distribution and limited distribution releases?"
Please contact your storage vendor to discuss whether you should upgrade to the latest available Storport.sys, vendor-specific MPIO DSM, HBA drivers, etc.
