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
