Currently, the scsi error handler will issue a START_UNIT command if the drive indicates it needs its motor started and the allow_restart flag is set in the scsi_device. If, after the scsi error handler invokes a host adapter reset due to error recovery, a device is in a unit attention state AND also needs a START_UNIT, that device will be placed offline. The disk array devices on an ipr RAID adapter will do exactly this when in a dual initiator configuration. This patch adds a single retry to the EH initiated START_UNIT. Signed-off-by:

Attached is the patch I feel will address this issue. As an added 'perk' I have also added the code to detect if the controller was previously initialized for interrupted operations by ANY operating system should the reset_devices kernel parameter not be set and we are dealing with a naïve kexec without the addition of this kernel parameter. The reset handler is also improved. Related to reset operations, but not pertinent specifically to this issue, I have also altered the handling somewhat so that we reset the adapter if we feel it is taking too long (three minutes) to start up. We have not unit tested the reset_devices flag propagation to this driver code, nor have we unit tested the check for the interrupted operations under the conditions of a naively issued kexec. We are submitting this modified driver to our Q/A department for integration testing in our current programs. I would appreciate an ACK to this patch should it resolve the issue described in this thread... Signed-off-by:

This patch fixes a problem discovered on a system with some bad SATA devices attached. If a command to a SATAPI device times out and the device gets reset as part of error recovery, its possible that ipr will set err_mask to indicate a device error has occurred. If this happens, a request sense will get issued by libata. Since scsi core thinks this scsi command is now completed, because the device reset handler completed successfully, scsi core will free the associated scsi command, which may cause an oops when that request sense is completed later by ipr. This patch ensures that any commands that get aborted as a result of a device reset set err_mask appropriately so that the request sense does not get sent. Signed-off-by:

The ipr driver has a sysfs attribute which can be used to adjust the logging level of the driver for error events. The error response data for commands can be dumped by increasing the logging level of the ipr driver. This currently only works for JBOD passthrough devices. This patch enables this function for all devices, including RAID devices, to aid in debugging problems. Signed-off-by:

The Adapter build date that is to be printed on instantiation was not displayed as a result of the supplemental adapter information structure not being in sync with the Firmware; the driver took an early test cycle version that had a miss-sized padded region at the head and the structure was not re-checked at the end of qualification. The Build Date was not a priority and is merely a cosmetic enhancement, and the wrong location for the start of the structure member would not induce any side-effect problems. We updated the structure to match the actual format, and added the TSID (Tech Support Identification) value print, should it be present, to the adapter instantiation announcements during driver load. This later enhancement should improve the relationship between Service folk & Tech Support if the printed value of the TSID found it's way into the circular file labeled G... Neither of these values show in sysfs (yet). Signed-off-by:

Just sweeping the floor clean in one spot. Some of these constants have never been used in the driver or in the firmware (and thus are meaningless). Triggered this patch because I discovered one of the unused constants was actually incorrect and figured it was better to clean them out than correct and update. There are no side effects at all regarding this patch, it is purely cosmetic. Signed-off-by:

Unsigned long is not always the same size as a pointer, namely on 32 bit systems with 64 bit address space. Ptrdiff_t is the same size as a pointer in all configurations. By using ptrdiff_t we can mitigate the warning messages on these configurations. There should be no side effects of this patch. Signed-off-by:

We have seen two cases where VPD on an emulex card has been incorrect and we end up walking off the end of memory. It looks like someone made an update (increased the length of a string) without increasing the Length field. Then we do: Length -= (3+i); And since Length is unsigned it becomes very large and we loop forever in the encapsulating: while (Length > 0) { If we make Length signed then we fall out of the loop and proceed on. Its important to note we have only seen this in the lab and it may be the only two cases of this in existence, but since the rest of the code has been written to be resilient against bad VPD we may as well fix this too.

There is some residual cleanup of the last series of patches and the need to bump the revision number to draw the line in the sand. The cmd->SCp.phase is set in the aac_valid_context routine, then set again to the same value following it's return. The cmd->scsi_done is set twice in the aac_queuecommand routine. Free up the scsidev FILO in aac_probe_container as it is not needed further down the function in any case. Improve the efficiency of the abort handler kernel print parameters. Bump revision number of driver to approximate the equivalent in the Adaptec supplied version. Signed-off-by:

Captured a panic on an older kernel where an application issuing commands via sg was sending requests that lacked a request_buffer, thus the buffer pointer used in aac_internal_transer was NULL. The application was fixed closing the issue, but felt it was advised to immunize the driver against the eventuality. Signed-off-by:

Implement SBC START/STOP management. sdev->mange_start_stop is added. When it's set to one, sd STOPs the device on suspend and shutdown and STARTs it on resume. sdev->manage_start_stop defaults is in sdev instead of scsi_disk cdev to allow ->slave_config() override the default configuration but is exported under scsi_disk sysfs node as sdev->allow_restart is. When manage_start_stop is zero (the default value), this patch doesn't introduce any behavior change. Signed-off-by:

This address the issue of VMWare guest OS being remounted as read-only becuase the underlying device was held busy too long and at the same time address Engenio MPP driver concerns over infinite retries. This patch removes the code that snoops the SAM STATUS on busy, which would be returning DID_BUS_BUSY, instead we return the status as is. Retry hanlding seems to be properly handled in scsi_softirq_done, where a busy sam status would only occurr for the time specified by (cmd->allowed +1) * cmd->timeout_per_command. Signed-off-by:
