DSS V6 iSCSI Failover with XenServer

Hey,

I'm currently running an open-e dss v5 since years without any problems.

So I wanted to setup the v6 dss with volume replication and failover lan and downloaded the free trial 6.0up65.xxxx.5217.

After some days of trying without any success in different constellations, I built up *exactly* the same network described in this manual: http://www.open-e.com/download/libra..._file/get/363/
means, I chose the same networks, IPs, two switches, two pingnodes etc.
But it doesn't work!
I always get the messages "Configuration of both nodes finished with errors" in step 8, trying to start the failover service. The service doesn't start. The status of the ping nodes is ok, everything else is down or unknown.

Is there any failure known in this version respective this error?

THX for helping me.

So to make sure that I understand your are doing this with 2 DSS V6 and not with your DSS V5 to DSS V6 - correct?

If you are doing it with 2 DSS v6 make sure your SCSI ID and LUN# and Target names are the same. Make sure you have the Aux for the Volume Replication NICs and for the Pri. and Sec. Nodes.

Video might helps as well.

2010.06 Open-E DSS V6 Synchronous Volume Replication with Failover over LAN

Wow, fast answer. THX. :)

You're right, I have two DSS V6 in the same configuration.
Setup as shown in the pdf, networks 192.168.0.x to 192.168.3.x. Left side is .230, right side .240.
SCSI ID is on both sides 0000000000000000 and LUNs are 0.
AUXs are set, checked every setting twice (or more ;) ).

I know the video, I have seen some good webinars with a german presenter (Janusz Bak).

Still doesn't working. :(

Are you using XenServer ?
As you can find more PDF files about Failover at our library:
http://www.open-e.com/library/how-to-resources/

Also you can save your old settings from your old system (DSSv5) and apply them to your Trial DSSv6. (some settings may not work).

To save your configuration and setup settings from the GUI in MAINTENANCE -> miscellaneous -> Function: Save settings. ( same place to restore "reload" them).

Give me the setup for Source and Destination. Also is the Volume Replication completed?

Source:

IP of the Volume Replication (Aux)
Primary Node IP (Aux)
Ping Node
VIP

Destination:

IP of the Volume Replication (Aux)
Secondary Node IP (Aux)
Ping Node
VIP

Yes, I am using Citrx Xen 5.5 with the V5 and in the new scenario 5.6 with the v6.
But with the old v5 I am not using failover, so export/import settings is obviated.

The pdf "How to setup iSCSI Failover with XenServer" helps me to configure the xen, but unfortunately I don't get to that point. So, how far does the Xen has to be configured, when I am trying to start the failover service? Does he play any role at this point? Configuring the Xen in the mentioned way let the dss service still tell me "Configuration of both nodes finished with errors".

Thanks again.

For the Auto Failover XEN is not needed, we are just trying to get an over view.

First, at this point, great support! I am exalted. :)

Does this message in the syslog helps you?

COMMAND=/var/nasexe/Heartbeat/failover_monitor
[user.err] cl_status: [13698]: ERROR: Cannot signon with heartbeat
[user.err] cl_status: [13698]: ERROR: REASON: hb_api_signon: Can\'t initiate connection to heartbeat

It looks like some connection issue - if you want send me a privet email in the forum and I will send you a Netviewer session to look at your system.

Todd,
u got mail. ;)

check you email for the link that I sent.

Check the link that you sent, it refers to the forum. ;)
I answered a few minutes ago. :p

Looks like your connected now.

Yeah, it really works now.
I set the aux on eth1 & eth2 (vip) wrong. Without the heartbeat on it, it works.
Todd helped me a lot.
Thanks very much.
Really great forum.
Thumps up!!!

Glad we can help :)
