Severity: Major

Alarm Description: HyperMetro is disconnected

Handling Process

Collect the hardware logs  in order to see if any part is faulty, the link or some disk.

 

Root Cause

The HyperMetro link down because datacenter lost power.  In the meanwhile, the Quorum server of HyperMetro domain in datacenter, was disconnected because of network issue.

Solution

Since the 18500V3 storage in datacenter found HyperMetro link and Quorum server was down at the same time,based on HyperMetro mechanism, it will suspend the service and waiting for engineer to manually restore.

For the 18500V3 storage in datacenter, after power on again, the system is designed that it needs manually determine the external fault, and recovery (such as network storm, single site failure).

So, they both set the HyperMetro LUN as local resource access denied
