Subject: [LSF/MM TOPIC] SCSI referrals support
Date: Thu, 20 Jan 2011 17:00:10 +0100 [thread overview]
Message-ID: <4D385C0A.3000901@suse.de> (raw)
Agenda topic proposal:
SCSI referrals support has already been discussed at last year's LSF
conference. However, the solution proposed there would not support
failover and would require quite a lot of changes to multipathing.
To enable failover it might be an idea to handle the LUN directly in
multipathing. This would require eg:
- request splitting
- I/O alignment handling
- SCSI unit attention handling
I would be giving a short overview/presentation of the current
state of the art, the shortcomings on the original proposal,
and would like to invite a discussion on how to best support
SCSI referrals.
Cheers,
Hannes
