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.

This makes it a little easier to find the boundaries between the various stages of command processing in trace output. Note, this patch does not implement a 'finished' message for TM events; there is already a "TM reply" message that can serve that purpose. Signed-off-by: Steven J.

Vladislav Bolkhovitin	e1447ae241	Add implicit ALUA support. On a setup with more than one target port ... (sometimes called storage head) this patch makes it possible to tell the initiator which port to use. Since that information can be specified per LUN, with this patch it is not only possible to tell the initiator which path to choose but also to balance the load over target ports. Target port attributes can not only be defined for target ports that exist on the system on which SCST is running but also for target ports present on other nodes of the same HA setup. As far as I know this feature is unique among open source storage target implementations. Note: with this patch SCSI target port attributes can be defined for each LUN defined on each SCST target individually. Such an SCST target is either a physical entity (e.g. a HCA for the ib_srpt driver) or a logical entity (e.g. an iSCSI target for the iscsi_scst driver). In the last case it is up to the user to make sure that there is a one-to-one relationship between SCST target and SCSI target port. This patch is based on the specifications in the ANSI T10 spc4r30 document.
