Subject: [SCSI] qla2xxx: Correct vport-state management issues during ISP-ABORT.
X-Git-Tag: v2.6.27-rc4~33^2~13
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a7a28504bfa61dc6caa495f55c52623d10b42b32;p=linux-2.6

[SCSI] qla2xxx: Correct vport-state management issues during ISP-ABORT.

* Use correct 'ha' to mark a device lost from ISR.
  I/Os will always be returned on the physical-HA.
  qla2x00_mark_device_lost() should be called with the HA bound
  to the fcport.
* Mark *all* devices lost during ISP-ABORT (bighammer).

These fixes correct issues discovered locally where during
link-perturbation and heavy vport-I/O fcport/rport states would
stray and an rport's scsi-target lost (timed-out).
