Hi all,
I've hacked up scsi_debug to support REPORT TARGET PORT GROUPS.
In combination with vpd_use_hostno=0 it'll now support multipathing
nicely.
Doug, there is reference to port_a and port_b in the VPD page support.
However, port_b appearently is just a fake entry with no (virtual)
device backing.
Hannes,
Yes, I was mimicking a SAS drive with the secondary port
unconnected.
Hmm. We could to that, too. Just set the secondary port to unavailable.
Let's see ...
We could eg use the 'channel' value to refer the relative port number,
so that host & channel act as a fan-out for multipathing.
I'll have a look, perhaps it could be wired when
vpd_use_hostno=0 .
Yep, that would be possible.
James, please apply.
Umm, I would like to find out why that patch oopses
my machine when I load the scsi_debug module.
Not my fault (I hope). Patch works when compiling under 2.6.18 ...
Cheers,
Hannes
