We've discovered a couple of these bypassed disk conditions via the flashing amber light - but this was noticed totally out of band with normal support
Each time we opened a case manually and Netapp immediately sent out a disk replacement.
So why is a bypassed disk not treated as a failed disk ? This kind of silent failure (in terms of Netapp monitoring and alerts) in a lights out datacenter seems negligent.
Message logged on syslog server:
esh.bypass.err.disk:error]: Disk 4d.49 on channels 4d/PARTNER disk shelf
ID 3 ESH A bay 1 Bypassed due to the drive self bypass.
BTW: I read the KB article on bypassed disks and ran the CMD to highlight BYP but it did not show BYP
