How to avoid stopping the failover when adding a new failover task?

Currently, I have two SAN servers in cluster with failover with multipath setup. In the initial setup, I only have one failover task running. When the failover service is running, I can't add another failover task. Is stopping failover service the only way before I can add new failover task?

If I stop the failover service, both virtual IPs will be inaccessible as well, then the hypervisor will lose connections to the SAN cluster. Any advice how to avoid service interruption when adding a new failover task? Thanks.

submit a support ticket, and I can give you a small update to make this work.
also make sure you are on the most current version of DSS V6

Thanks. I had submitted the ticket. I am using the DSS V6.

what is the build number?

Thanks. I received the file. I am going to test it.

Hi there!

@cloudtech: Did you test it? Any succes / advise?

@Gr-R: Is the update available at kb-open-e? Do I have to submit a ticket to get it as well.
We are testeing with a set of up90 storages right now.
We are planning to update our other storages to up90 as well asap.
So the version should be runnung for up90.

Will the functionality be available in the standard soon?

Thanks

Sorry for late reply. I haven't had a chance to test it since I could not apply the patch to existing build b5794 or upgrade to the latest build . Gr-R suggest me to re-install the DSS software, but I haven't had a time to do it.

You will need to submit a support ticket to get the small update.
I can make the update available for the following builds:
5377
5626
5794
5845

Between Christmas and New Year we updated all our storages to up90 (5845).
All the machines (VM) and the data residing on the storages have been available during the updateprocess due to the failoversystem we are using.

:) It worked flawless, thanks for that. :)

I will submit a support ticket to get the small update and report results later.

Am I right in assuming that this update includes the most needed function for DSS?

So after this update i can add some harddisks, configure my failover task for this drives, and add it to the failover without the need of shuting it down? No need to shutdown 20 VMs when adding a single drive to the SAN?

Well, i'm on up85 5794, where can i get this update?

Correct. this small update gives you the ability to add tasks to the failover configuration without stopping failover.
Submit a support ticket in your user portal, and request the update.

We are testing it right now (since a week).

It works fine so far. :)

We are glad to hear that, and we are planning to add this small update to our future new builds of DSS.

This small update ( upd_0904c-DSS-V6 ) is already included within the build up95. 6156 and after, so if you are running any build after up95.6156, then no need to this small update.
