PORT RECOVERY TIMEOUT is the maximum time between the controller's detection of the PHY down until the receipt of the ID_Frame (from the same remote SAS port). If the time expires before the ID_FRAME is received, the port is considered INVALID and can be removed. The IOP_EVENT_PORT_RECOVERY_TIMER_TMO event is reported following the IOP_EVENT_ PHY_DOWN event when the PHY/port does not recover after Port Recovery Time. Signed-off-by:

In pm8001_ccb_task_free(), the dma unmapping is done based on ccb->n_elem value. This should be initialized to zero in the task_abort(). Otherwise, pm8001_ccb_task_free() will try for dma_unmap_sg() which is invalid for task abort and can lead to kernel crash. Changes From V1: None Signed-off-by:

The driver is calling hpsa_shutdown before calling scsi_remove_host. hpsa_shutdown is disabling interrupts. scsi_remove_host can trigger I/O operations, such as SYNCHRONIZE CACHE when multipath is enabled which hang the system. Call scsi_remove_host before calling hpsa_shutdown. Reviewed-by:

A regression was introduced into the hpsa driver a while back so non-zero LUNs of multi-LUN devices may no longer be presented via a SAS based Smart Array. 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. Suggested-by:

Driver crashes if the BIOS do not set up at least one memory I/O resource. This failure can happen if the device is too slow to respond during POST and is missed by the BIOS, but Linux then detects the device later in the boot process.
