Experiences with updating DSS while Failover service is running

[prahn]

Hi!
Thank you for the fast reply.
What I do not understand: After both systems are updated I am running both in mode "SCST VPD 2.0".
Will I ever be able to switch both system back to the highest level? I guess I need to shutdown failover for that, right?
Any disadvantages?

As the note said :
- In case of updating from version 6.0up95 or higher, please change the Identification Device (VPD) compatibility to SCST VPD 2.1.

So we recommend you to change the SCST VPD to 2.1 in the console mode, by pressing CTRL+ALT+W -> Tuning options -> SCST subsystem options -> Device Identification (VPD) compatibility.

You can switch it after or during the update, and in general, tuning this option should work without need to reboot, but in case you are running virtual machine, we cannot be sure about it's behaviors, so rebooting would be recommended in this case.
