Failover task will not start

[brenno]

Hi,

The steps that I do when I extend a volume are:

- Remove replication task from failover task
- Stop and remove replication task
- remove LV from iscsi target (both nodes)
- remove replication from LV by modify LV (both nodes)
- extend LV by modify LV (both nodes)
- add replication to LV by modify LV (both nodes)
- set LV as destination on node2
- add LV to iscsi target (both nodes)
- create new replication task
- add replication task to failover task

At the last stage it stops... Please tell me which step I am missing...

What about this : The replication task IS running: FunxTestSync 2012-09-25 10:18:50.. is your task start after the error message?
Also are you running the latest build of DSS ? if not then please follow the following steps:
- Please save all settings in the Maint. > Misc. and take all options.
- Stop the secondary system,
- Update the secondary system to new version,
- Start the secondary system,
- Wait for replication to be consistent,
- Start manual failover,
- Stop the primary system,
- Upgrade the primary system,
- Start the primary system,
- Wait for replication to be consistent,
- Start failback.

When it stopped at the last stage as, does it gave you error then continue, or only stopped ?

Hi,

We are currently running version 6.0up97.xxxx.6335 2012-06-22 b6335
Should be the latest version available at the moment.

After I recreated the replication task I also start it.
After which I will then try to add it to the failover task.
At that point you get the 'disconnected' error message.

Funny thing is though. I just tried it again and it got accepted.
You just need to wait a few hours before it works, apparently...

Seems you have small mount of RAM of a very huge replicated storage. It shouldn't take hours! only some time but not hours!
You may send us a support ticket so we can check your system for you.

Just to be clear - to extend a volume I must stop Failover?

Yes and you must modify the volume and remove the Replication task associated with it then apply and then modify again with the added capacity and add the Replication again.

See video below explaining this procedure.
