Vertical port failover behaviour

Hello,

When the 2nd switch is rebooted it should fail back to the first switch at that time.  It does not fail back when the first switch comes back up automatically.

I would check the cabling and make sure the first switch was fully booted before rebooting the 2nd switch.

Regards,

Don

Thanks Don,

OK, I rebooted the second switch to test this. The two active switch ports on the bottom switch (In vertical port failover) flipped to the top switch, so no data loss but the array is still in vertical failover even after both switches are operational.

The only way to correct this is to pull a cable on the standby controller which then corrects the situation, the end result being that the live ETH ports are on the Active CM.

I would have thought that the EQL has the intelligence to make sure that live ETHs were on the active CM. Especially as LLDP is advertising the switch name and port.

Since it's only the connector being used there's really no need to failback.  

Hi Don,

Perhaps I should have stated from the start that this is a PS6210 with two ports per CM.

That's ok, same principle.   That active CM can use either physical port, and switch back and forth w/o a problem.
