Event code: 061
Message: Fabric controller database invalid.
Severity: Minor.
Explanation: Following a CTP card failover or replacement, IML, or firmware download, the fabric controller database failed its
CRC validation. All fabric controller databases are initialized to an empty state, resulting in a momentary loss of
interswitch communication capability.
Action: Perform the data collection procedure and return the CD to IBM support personnel.
Event Data: No supplementary data included with this event.

Event code: 062
Message: Maximum interswitch hop count exceeded.
Severity: Informational.
Explanation: The fabric controller software detected that a path to another fabric element (director or switch) traverses more
than seven interswitch links (ISLs or hops). This may result in Fibre Channel frames persisting in the fabric longer
than standard timeout values allow.
Action: If possible, reconfigure the fabric so the path between any two directors or switches traverses no more than
seven ISLs.
Event Data: Byte 0 = domain ID of the fabric element (director or switch) more than seven hops away.
Bytes 1 - 3 = reserved.
