   1 From: Gerald Schaefer <geraldsc@de.ibm.com>
   2 Subject: zfcp: erp failed status bit will not be set
   3 References: bnc#482818,LTC#51962
   4
   5 Problem:     It will not be necessary to set the erp failed status bit
   6              in case a scsi device is removed by the scsi mid layer.
   7              In the case a scsi device is unavailable for a short time
   8              (15 to 20 seconds) a FCP unit will not get on-line again.
   9 Solution:    Do not change the status bits if slave destroy is called.
