Subject: [patch 16/18] [PATCH] zfcp: erp failed status bit will not be set
Date: Mon, 02 Mar 2009 13:09:09 +0100 [thread overview]
Message-ID: <20090302121004.183095000@de.ibm.com> (raw)
In-Reply-To: 20090302120853.279447000@de.ibm.com
[-- Attachment #1: 717-zfcp-erp-status-bit.diff --]
[-- Type: text/plain, Size: 975 bytes --]
From: Martin Petermann <martin@linux.vnet.ibm.com>
It will not be necessary to set the erp failed status bit
in case a SCSI device is removed by the SCSI mid layer.
In the case a SCSI device is unavailable for a short time
(15 to 20 seconds) a FCP unit will not get on-line again.
