Toasters,

This might be a descent time to ask. What actions are taken to resolve "Link Failure" and "Loss of Sync". Both Underruns and Invalid CRCs aren't really a concern since it should generate a resend, or at work a loop reset to clear any blockage. However, I'm curious what happened after a Link Failure and Loss of Sync. On most systems I'd assume this would result in a LIP. I suppose you could respond to a Link Failure with a full loop reset (rather than LIP) but I'm not sure how their being handled.

Is there comeone familiar enought with FC on the Filers to comment on which actions are taken to resolve each of these states at the FC level?

Thank You.

Ben Rockwood

I need a little advise on what this all means below in regards to the FC LINK STATS for my F760. I'm running DOT 6.2.1 with 1 FC8 drive shelve with 7 18GB drives. I'm not to sure if this is the beginning of a failed disk or what. Any info would be appreciated.
