* [SCSI] zfcp: Use correct width for timer_interval fieldChristof Schmitt2010-07-282-1/+3
| | | | | | | | | The timer_interval is 14 bits in width. Introduce a define for properly masking the value. Reviewed-by: Swen Schillig <swen@vnet.ibm.com> Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] zfcp: Remove SCSI device when removing unitChristof Schmitt2010-07-283-2/+10
| | | | | | | | | | | | Configuring a LUN in zfcp, also creates a SCSI device. For consistency, it makes sense to remove the SCSI device when the LUN is deconfigured. Replace the flush_work with the call to scsi_remove_device: scsi_remove_device also takes the scan_mutex that synchronizes itself with any long running device discovery.

* [SCSI] zfcp: Use forced_reopen in terminate_rport_io callbackChristof Schmitt2010-07-281-3/+5
| | | | | | | | | | | | | When running in non-NPIV mode, the port_reopen in terminate_rport_io might succeed even though the remote port is not available. If the same port connection is held open from another operating system, the reopen is only a virtual operation and might not hit the SAN. Fix this by changing the call to forced_reopen that forces a logout/login operation in the SAN.

* [SCSI] zfcp: Register SCSI devices after successful fc_remote_port_addChristof Schmitt2010-07-285-17/+33
| | | | | | | | | | | | | | | | | | | | | When the successful return of an adisc is the final step to set the port online, the registration of SCSI devices might be omitted. SCSI devices that have been removed before (due to a short dev_loss_tmo setting) might not be attached again. The problem is that the registration of SCSI devices is done only after erp has finished. The correct place would be after the call to fc_remote_port_add to mimick the scan in the FC transport class. Change the registration of SCSI devices to be triggered after the fc_remote_port_add call. For the initial inquiry command to succeed, the unit must also be open. If the unit reopen is still pending, the inquiry command to the LUN will be deferred with DID_IMM_RETRY, so there is no harm from this approach.

| | | | | | | | | | | | | | Trying to read the FC host statistics on an offline adapter results in a 5 seconds wait. Reading the statistics tries to issue an exchange port data request which first waits up to 5 seconds for an entry in the request queue.

A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...)
