A fibre switch stack, in a redundant pair, suffered a fault at 13:16 today.
The effect of this was a loss of redundant paths to both the Central Storage Platforms and to all connected servers.
There was no loss of service in this event, just a loss of redundancy.
Engineers visited the Data Centre in question and brought the fibre switches back online at 13:52.
Some additional paths within the fabric had to be created to restore full connectivity. Diagnosis is not yet complete and so it is currently unknown if any further remedial action is required.
There has been no loss of service during this event, only a loss of redundancy.
Loss of resilient paths in Storage Area Network (SAN)
users should see no impact.
administrators of systems will see the loss of some paths to the SAN.
