Thank You !

Got that update already, we have multiple systems running here,
but they were all updated some time before to up80,
before we went to up90.

I'll give it a try.

Looking to our systems already running on up90,
the failover on I/O errors is already enabled by default
so we don't have to configure this.
Good idea, because we could not configure this anyway,
since for configuration changes we would have to stop failover...

Regards,
Ralph
