Subject: RE:[PATCH 05/14] IB/srp: Maintain a single connection per I_T nexus
Date: Wed, 12 Jun 2013 16:29:27 +0200 [thread overview]
Message-ID: <51B885C7.1020701@profitbricks.com> (raw)
> An SRP target is required to maintain a single connection between
> initiator and target. This means that if the 'add_target' attribute
> is used to create a second connection to a target that the first
> connection will be logged out and that the SCSI error handler will
> kick in. The SCSI error handler will cause the SRP initiator to
> reconnect, which will cause I/O over the second connection to fail.
> Avoid such ping-pong behavior by disabling relogins. Note: if
> reconnecting manually is necessary, that is possible by deleting
> and recreating an rport via sysfs.
