We encountered this in ESX, which relies on these 2 bytes to parse the MISCOMPARE sense code (0xE1, 0x1D, 0x00). Bellow is a simple test to recreate this issue, but during vMotion operations (where VMs are moved from one host to another), this may cause the operation to fail leaving the VM in an inconsistent state. The test I ran to verify that we are indeed missing the bytes is the following: 1. Create a SCST based device 2. Expose the device to 2 ESX hosts 3. Format the device as VMFS5, create a test directory 4. From both hosts, I start writing to this directory (no VMs involved, just write normal files) At this stage, both ESX hosts try to take access to the directory. The VMFS filesystem contains a per-directory lock which is managed by COMPARE AND WRITE command. Each ESX will attempt to change the VMFS lock location from unlocked to locked to create the new file. Obviously there are bound to be failures (which are equivalent to programming locking conflicts), these are reported by the MISCOMPARE sense code. Upon these MISCOMPARE errors, the host will re-try taking the lock until it succeeds, and will then proceed to perform the write operation on the directory. Due to the bug in copying the sense buffer from the SCST core to the QLA ctio, instead of the full sense code, only the key (0xE) is sent, and ESX does not know how to handle it resulting in IO error. Here are the errors as they appear on the command line: /vmfs/volumes/54a297c4-ca5af1cc-7f94-002219d20f28/ats_test # ./open_close_test-esx2.sh ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_1.txt: Input/output error ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_21.txt: Input/output error ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_110.txt: Input/output error ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_111.txt: Input/output error In the /var/log/vmkernel.log, we can see that the sense information is missing (0xE, 0x0, 0x0) instead of (0xE, 0x1D, 0x0). 2014-12-30T12:13:20.714Z cpu6:33519)ScsiDeviceIO: 2338: Cmd(0x412e84f957c0) 0x89, CmdSN 0x234d from world 519051 to dev "eui.0024f400d5020007" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x0 0x0. 2014-12-30T12:13:20.766Z cpu6:33519)ScsiDeviceIO: 2338: Cmd(0x412e84f91d00) 0x89, CmdSN 0x2350 from world 519051 to dev "eui.0024f400d5020007" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x0 0x0. 2014-12-30T12:13:20.766Z cpu6:33519)ScsiDeviceIO: 2338: Cmd(0x412e80449fc0) 0x89, CmdSN 0x234f from world 519051 to dev "eui.0024f400d5020007" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x0 0x0.
