I have a Dell ML-6020 ( rebadged ADIC Scalar ) tape library with six drives direct-attached to a DCX-8510-8B
The libary works well, but on occasions one or more ports are fenced by FOS on account of excess Invalid Words.
We're monitoring this in order to learn more, but I have noticed that, of the 6 drives, two have slightly different outputs for portshow:
portFlags: 0x20b03 PRESENT ACTIVE F_PORT G_PORT LOGICAL_ONLINE LOGIN NOELP ACCEPT FLOGI
portFlags: 0x24b03 PRESENT ACTIVE F_PORT G_PORT LOGICAL_ONLINE LOGIN NOELP LED ACCEPT FLOGI
Now, I do see this bitmap on other, non-tape ports, but there's no obvious pattern.
So, can anybody explain:
Many thanks for any insights you are able to share
