SMBDirect --------- - 41620: One of the system hits BSOD while upgrading drivers on cluster nodes. - 39745: Rebooting machine with SMBDirect traffic is not supported. NOTE: This is not a Chelsio driver issue. On rebooting the machine with heavy SMB traffic, the shutdown takes long time as disabling NDK gets stuck in the stack modules. This issue is not seen with the latest Windows OS builds. - 38987: "AE qpid" messages observed on doing link unplug and plug with VMfleet traffic running on the S2D cluster. NDIS SR-IOV ----------- - 41127: "ReadVfConfigBlock failed" messages observed in VM with VFs and Guest RDMA enabled by disabling host NDIS driver. - 40522: System hits BSOD on rebooting host with 17 VMs (each having 2 vnics) connected to SR-IOV enabled SET vSwitch. NOTE: This is a Microsoft issue. The issue will not be seen if using 16 VMs (each having 2 vnics, for a total of 32 VFs). The issue is resolved with latest Windows OS builds. - 38887: RDMA connection fails to establish when tried to access the share of other VM using same vswitch. - 38726: Host machine hits BSOD by rebooting VM's after mode 3 traffic. NOTE: This is not a Chelsio driver issue. BSOD occurs because a pnp event is improperly issued. The issue is resolved with latest Windows OS builds. - 37069: Disable/Enable NDIS with SRIoV and vRSS interfaces connected to VM is not supported. - 36921: Issues seen on VM while uninstalling and installing the VF driver multiple times. NOTE: This is Microsoft issue. As a workaround, reboot the host machine if the issue is encountered. - 36847: Need iSER and NVMe-oF support over Guest RDMA. iSCSI Storport Miniport ----------------------- - 41161: Session fails to reconnect after link toggle. - 40777: iSCSI queues not getting updated while running traffic. - 39046: [T6225-SO]: RW numbers drop for IO size > 128K. - 33200: Need mechanism to notify ip conflict. iSER Storport Miniport ---------------------- - 41839: Rebooting the Initiator with targets logged in is not supported. - 40681: With SET switch configured, iSER initiator's IP is not shown for discovery. Workaround: Once SET switch is configured with IP address and RDMA, disable and enable the VBD. - 36705: Only 32 connections are supported on T6 SO cards. - 35703: Discovery/Login does not work, when iwpmd service is running on Target. - 34687: Logout time is slower.
