Hi William,
A LC stuck in Waiting to retry can have multiple causes but it is too difficult and long to properly troubleshoot this here.
Anyway the causes might be:
1- LCs failed (2 of them is pretty rare but can happen) > solution is RMA
2- Backplane issue > solution is replacing the chassis
3- Something between the RP and that slot gets hung up and the RP cannot properly communicate with the LC. It could be a sw issue. i.e. CSCsz12469 LC will not boot after MBUS_SYS-3-NOBUFFER & PRP-3-CHP_DESCQ_FULL error
4- RP problem (rare).
What I would do is (following the order):
- reseat (physically) the cards. Probably you did it already
- try use another slot (if all are busy move other cards to those 2 slots and those cards to those slots. That would verify bullets 2 and 3.
- RP switchover (if redundant RP is present).
- Engage the TAC to troubleshoot from the fabric perspective (too complex here).
Good luck
Riccardo
