| * | | [SCSI] zfcp: Remove flag ZFCP_STATUS_FSFREQ_TMFUNCNOTSUPPChristof Schmitt2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flag ZFCP_STATUS_FSFREQ_TMFUNCNOTSUPP is never set and hence can be removed. This is a leftover from the time when zfcp had to decide whether the target supports a "logical unit reset" or not. Nowadays, the SCSI midlayer calls the eh_device_reset_handler or the eh_target_reset_handler and zfcp simply maps this to a "logical unit reset" or a "target reset".

The zfcp hbaapi already has this information hardcoded, but this would allow to switch from the coding in the zfcp hbaapi to the common FC transport attributes in the future.

| * | | [SCSI] zfcp: Block scsi_eh thread for rport state BLOCKEDChristof Schmitt2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case the SCSI error recovery starts because of a SCSI command timeout, but then something else triggers the rport to be deleted, the SCSI error recovery will run to the end and set the SCSI device offline. To prevent this, call the FC transport function fc_block_scsi_eh which waits until the rport leaves the BLOCKED state. This guarantees that communication is possible if the rport is ONLINE, or the SCSI devices will be removed if the rport state switches to NOT_PRESENT.

Returning DID_TRANSPORT_DISRUPTED is a better approach, use this for reporting FSF errors back to the SCSI midlayer. See http://marc.info/?l=linux-scsi&m=125668044215051&w=2 as reference. There is also no need in special treatment of ABORTED commands, so remove the ZFCP_STATUS_FSFREQ_ABORTED, the commands are then returned with DID_TRANSPORT_DISRUPTED. Also remove the ZFCP_STATUS_FSFREQ_RETRY: It is useless, no retry is happening in the FSF layer and nobody checks the state of this flag.

The SCSI midlayer will retry the commands and fc_remote_port_chkready will return the correct status code. But with the delay between calling scsi_done in softirq context and the call to fc_remote_port_delete from the workqueue, there is a window where zfcp returns DID_ERROR. This leads to SCSI error recovery which then leads to offline SCSI devices since all recovery actions will fail with the rport now being blocked. In this window, zfcp has to return DID_IMM_RETRY just as the FC transport class would do in fc_remote_port_chkready for the blocked fc_rport. As soon as the fc_rport is BLOCKED, fc_remote_port_chkready will do the right thing. Additionally, there are two more cases to catch in zfcp_scsi_queuecommand: - After the port has been opened, the unit has to be opened. During this period I/O has to be retried. This can also be handled with DID_IMM_RETRY. - If the access to the unit fails, but the port is good, then this single unit cannot be accessed and I/O to this unit has to fail without involving the FC transport class.
