Manually failover Unity NAS Server to other SP?

Question

Is there a way to manually failover the Unity NAS Server (from SP A to SP B, or vice versa) without rebooting the SP? It appears that just disconnecting the Ethernet ports does not cause the failover.  Would like to perform a test, similar to how we used to test data mover failover without impacting any block access. Many thanks in advance.

You can change the SP a NAS server resides on. There's a drop down in the NAS server properties to select the SP.

I dont think there is a way short of rebooting the SP

Disconnecting network ports will not do the failover (which is why trunking is recommended for production).

For any test/maintenance, the required SP should be set to maintenance/service mode (which does the reboot and failover the services to peer SP).

However, in future code release, it will have this feature.

Thanks Chris, is this the same impact as an SP failover ?

Hi, is anyone aware of this functioanilty being released in current/future unity systems ? failover of NAS without SP reboot/failover. Many Thanks, Vivek

IMO it would be similar to a managed/graceful failover between the two SPs rather than a catastrophic failover.

IF you want to really test SP failover then you need to do a real failover - like rebooting the SP
