Solution

Review the status screen and/or the DOP of the VTSS for issues.

This error typically does not fence a FRU, but is indicating communications issue which is often a cable or in the customer's ESCON channel network. 

If a Host system has been reset recently, it will generate a high volume of errors that exceeded the expected threshold.

TSC Troubeshooting process:

1. Retreive the base files from the VTSS for review.
2. Review the hic_stat.dia the verify the box did generate the FSC32CB SIM/MIM
3. Review the pfaelg4a.cnt and pfaelg4a.dom files to see the number of temporary errors logged and to which channel ports they are on.
4. Review the status screen and/or the DOP of the VTSS for issues.
5. If multiple ports, identify the ports that have a very high volume of errors in order to help the customer identify a common external source.
6. If one port only, identify the ICE card.

Before replacing a channel card, perform the following.

1. Clean cables
2. Swapped cable for the port receiving the CHK2 errors with a known, good port or cable.
3. Replace the cable connected to the bottom port or replace both cables attached to this card ICE13.
