| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce support for enhanced I/O error handling. A device state is added to track 3 possible states of the device: Normal - the device is operating normally and is fully operational Limbo - the device is in a reset/recovery scenario and its operational status is paused Failed/terminating - the device has either failed to be reset/recovered or is being terminated (removed); it is no longer operational All operations are allowed when the device is operating normally. When the device transitions to limbo state, I/O must be paused. To help accomplish this, a wait queue is introduced where existing and new threads can wait until the device is no longer in limbo. When coming out of limbo, threads need to check the state and error out gracefully when encountering the failed state. When the device transitions to the failed/terminating state, normal operations are no longer allowed. Only specially designated operations related to graceful cleanup are permitted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scsi_error: should not get sense for timeout IO in scsi error handler When an IO timeout occurs, the IO will be aborted in scsi_abort_command() and SCSI_EH_ABORT_SCHEDULED will be set. Because of that, the SCSI_EH_CANCEL_CMD will be clear in scsi_eh_scmd_add(). So when scsi error handler starts, it will get sense for this timeout IO and the scmd of the IO request will be reused. In that case, the scmd may be double released when racing with io_done(), which will result in crash. SO SCSI_EH_ABORT_SCHEDULED should also be checked when getting sense. The bug maybe reproduced when the link between host and disk is unstable.

I have not done a bisection to discover the change that caused it. The CISS firmware specification (available on sourceforge) defines an 8 byte lunid that describes devices that the Smart Array can see/present to the system. The current code in the hpsa driver attempts to find matches for non-zero LUNs with LUN 0 for a bus/target by zeroing out byte 4 of the lunid and find a match. This method is sufficient for SCSI based Smart Arrays because byte 5 is always 0. For SAS based Smart arrays byte 5 of the lunid contains the path number for a multipath device and either one or two bits (the documentation does not define how many bits are used but it appears it may be one only) that indicate if the given path number in byte 5 must always be used to access that device. Byte 5 may not always be zero. The following are lunids (spaces added for clarity) for a MSL2024 single drive library connected via a H241 Smart Array: 00 00 00 00 01 00 00 01 (changer) 00 00 00 00 00 80 00 01 (tape) In the 4th byte (counting from 0) you can see that the tape is LUN 0 and the changer is LUN 1. The 0x80 set in the 5th byte for the tape drive means the driver should force access to path 0 (the library in this case was connected to one path only anyway). After the changes we can see the following in the dmesg output: scsi 0:3:0:0: RAID HP H241 1.18 \ PQ: 0 ANSI: 5 scsi 0:2:0:0: Sequential-Access HP Ultrium 6-SCSI 354W \ PQ: 0 ANSI: 6 scsi 0:2:0:1: Medium Changer HP MSL G3 Series 8.70 \ PQ: 0 ANSI: 5 Showing that the changer is correctly identified as LUN 1 of bus 2 target 0. Before the change the changer device is not seen.
