I got a great question recently:
We just updated our Cisco MDS9509s to NX-OS 4.2.7b (from Cisco SAN-OS 3.3.1c) and now we are getting emails from this source: GOLD-major.
The actual message looks like this:
Time of Event:2012-03-05 15:07:21 GMT+00:00 Message Name:GOLD-major Message Type:diagnostic System Namexxxx Contact Namexxx@xxx.com Contact Emailxx@xxx.com Contact Phone:+61-3-xxxx-xxxx Street Addressx Road, xxxx, VIC, Australia Event Description:RMON_ALERT WARNING(4) Falling:iso.220.127.116.11.18.104.22.168.1.10.18366464=2401032512 <= 4680000000:135, 4 Event Owner:ifHCOutOctets.fc4/5@w5c260a03c162 ThresholdType:FallingThreshold
So who is GOLD-major?
GOLD actually stands for Generic OnLine Diagnostics. From Cisco's website:
GOLD verifies that hardware and internal data paths are operating as designed. Boot-time diagnostics, continuous monitoring, and on-demand and scheduled tests are part of the Cisco GOLD feature set. GOLD allows rapid fault isolation and continuous system monitoring. GOLD was introduced in Cisco NX-OS Release 4.0(1). GOLD is enabled by default and Cisco do not recommend disabling it.
So in our example GOLD is actually reporting a major event (to do with exceeded thresholds, in this example utilisation on interface fc4/5).
Most clients using Cisco MDS switches are now moving to NX-OS (over SAN-OS, the name Cisco used for MDS firmware between version 1 and version 3) so this question will become more common. I am working on a post that discusses recommended versions (and the sunsetting of SAN-OS), so expect something soon. If on the other hand you are thinking.... how do I setup call home on a Cisco MDS switch? The information for NX-OS is here.
