src/patches/suse-2.6.27.39/patches.arch/s390-12-03-zfcp_adjust_test_link_pre_reqs.patch

   1 From: Gerald Schaefer <geraldsc@de.ibm.com>
   2 Subject: zfcp: no port recovery after storage side error inject
   3 References: bnc#487755,LTC#52402
   4
   5 Symptom:     The remote port remains in error state even if connection
   6              is re-established.
   7 Problem:     A wrong precondition check was performed on the port status
   8              leading to a cancellation of the port reopen.
   9 Solution:    Remove the pre-req check because it's not required and better
  10              handled within the ERP.
