#22 multiple paths under Linux

[Anonymous]

Hi,

my Target has two NIC´s
1. 192.168.0.1
2. 10.0.0.3

I need to see multiple paths to one disk, because I need
to test a management tool. My config file looks like that:

DiscoveryAddress=192.168.0.1
DiscoveryAddress=10.0.0.3

When I start iscsi under SLES8 he connects to both
portals, with iscsi-ls he shows me that he is connected
to 10.0.0.3. If this path is corrupted he switches
automatically to 192.168.0.1. So the Failover works.
But what I need is that I have the target bound in over
two paths, so I see the devices double.

Could you give me an example of a config-file?
I tried a lot, but I don´t get it work...

thanks a lot

In the 3.x driver you can find the details in the MULTIPATH
SETTINGS section of the conf file.

Hi,
I have read the manpage, and some other docs, but I want to
see two SCSI Instances in the OS, so that i have under
/proc/scsi/iscsi two paths assigned to my Target.

I enabled multipath (multipath=yes and tried portal) switched
off failover. But with this settings I even dont get a connection
to my Target Portal...

So How can I manage it to see my iSCSI Target under two
paths or instances?

right now my config file looks like this:

DiscoveryAddress=192.168.0.1
DiscoveryAddress=10.0.0.3

HostIPforMP=192.168.0.1,10.0.0.3

for example when I connect a Storage system via
Fibrechannel in a redundant way, with two paths I see all
devices double. Cause the OS can speak to the devices from
two paths. So how can I get this via iSCSI?

thanks

How about

Multipath=yes
PortalFailover=no

in the iscsi.conf

Hi,
this I tried, so the settings I had activated were:

iscsi.conf
"
DiscoveryAddress=192.168.0.1
DiscoveryAddress=10.0.0.3

Multipath=yes
PortalFailover=no
"

with this configuration, he didnt even get a connection to the
Target. :(

Try this config file:
DiscoveryAddress=192.168.0.1
DiscoveryAddress=10.0.0.3
Multipath=no
PortalFailover=yes

or only
DiscoveryAddress=192.168.0.1
DiscoveryAddress=10.0.0.3
