| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On excessive bit errors for the FCP channel ingress fibre path, the channel notifies us. Previously, we only emitted a kernel message and a trace record. Since performance can become suboptimal with I/O timeouts due to bit errors, we now stop using an FCP device by default on channel notification so multipath on top can timely failover to other paths. A new module parameter zfcp.ber_stop can be used to get zfcp old behavior. User explanation of new kernel message: * Description: * The FCP channel reported that its bit error threshold has been exceeded. * These errors might result from a problem with the physical components * of the local fibre link into the FCP channel. * The problem might be damage or malfunction of the cable or * cable connection between the FCP channel and * the adjacent fabric switch port or the point-to-point peer. * Find details about the errors in the HBA trace for the FCP device. * The zfcp device driver closed down the FCP device * to limit the performance impact from possible I/O command timeouts. * User action: * Check for problems on the local fibre link, ensure that fibre optics are * clean and functional, and all cables are properly plugged. * After the repair action, you can manually recover the FCP device by * writing "0" into its "failed" sysfs attribute. * If recovery through sysfs is not possible, set the CHPID of the device * offline and back online on the service element.

| * scsi: core: save/restore command resid for error handlingDamien Le Moal2019-10-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a non-passthrough command is terminated with CHECK CONDITION, request sense is executed by hijacking the command descriptor. Since scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd() do not save/restore the original command resid, the value returned on failure of the original command is lost and replaced with the value set by the execution of the request sense command. This value may in many instances be unaligned to the device sector size, causing sd_done() to print a warning message about the incorrect unaligned resid before the command is retried. Fix this problem by saving the original command residual in struct scsi_eh_save using scsi_eh_prep_cmnd() and restoring it in scsi_eh_restore_cmnd(). In addition, to make sure that the request sense command is executed with a correctly initialized command structure, also reset the residual to 0 in scsi_eh_prep_cmnd() after saving the original command value in struct scsi_eh_save.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework from previous work by: Sujit Reddy Thumma <sthumma@codeaurora.org> Until now the scsi mid-layer forbids runtime suspend till userspace enables it. This is mainly to quarantine some disks with broken runtime power management or have high latencies executing suspend resume callbacks. If the userspace doesn't enable the runtime suspend the underlying hardware will be always on even when it is not doing any useful work and thus wasting power. Some low-level drivers for the controllers can efficiently use runtime power management to reduce power consumption and improve battery life. Allow runtime suspend parameters override within the LLD itself instead of waiting for userspace to control the power management.
