Subject: multipath-tools - checker for DDN S2A8500
Date: Wed, 26 Jul 2006 14:06:24 +0200 [thread overview]
Message-ID: <44C75AC0.1030905@ext.bull.net> (raw)
Hello,
When using multipath-tools 0.4.7, I would like to reports that DDN S2A8500 disk
array reports a wrong status whith 'readsector0' checker. 'directio' seems to be
the right checker for such storage system (see following logs).
Can you update hwtable.c in this way ?
