Good day,
Recently I have been getting these kinds of alerts from my HMC. It all
started when I connected an old DS6800 and the details are:
Node 1
Machine: 2498-B40
Serial: IBMCA107312B
Physical Interface: 6620
Logical Interface: 0020
Node 2
Machine: 1750-511
Serial: IBM130000715
Physical Interface: 0100
Logical Interface: 0000
I keep getting these errors about 3-4 per day with the exact same
interfaces specified. No others, just these.
When I look at the referenced SAN switch and I do a "porterrshow" things
seem fine:
frames enc crc crc too too bad enc disc
link loss loss frjt fbsy c3timeout pcs

I assume the interface given in the alert is in hex, so the error would be
about port 32 (which is indeed connected to the DS6800 controller 1, port
0).
As you can see the port seems to be fine.
The full portshow 32 is here:

As far as I can tell the port is doing just fine, and I have not received
any reports of connectivity issues to the actual DASDs.
Any suggestions on what is going on, or worst case - how I can disable
these alerts?
Regards,
