Subject: [ 08/59] SCSI: zfcp: fix adapter (re)open recovery while link to SAN is down
Date: Fri, 26 Jul 2013 13:52:32 -0700 [thread overview]
Message-ID: <20130726205014.696828830@linuxfoundation.org> (raw)
In-Reply-To: <20130726205013.795696531@linuxfoundation.org>
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Hansel <daniel.hansel@linux.vnet.ibm.com>
commit f76ccaac4f82c463a037aa4a1e4ccb85c7011814 upstream.
FCP device remains in status ERP_FAILED when device is switched online
or adapter recovery is triggered while link to SAN is down.
When Exchange Configuration Data command returns the FSF status
FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE it aborts the exchange process.
The only retries are done during the common error recovery procedure
(i.e. max. 3 retries with 8sec sleep between) and remains in status
ERP_FAILED with QDIO down.
This commit reverts the commit 0df138476c8306478d6e726f044868b4bccf411c
(zfcp: Fix adapter activation on link down).
When FSF status FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE is received the
adapter recovery will be finished without any retries. QDIO will be
up now and status changes such as LINK UP will be received now.
