RIOIP11

Use this procedure to recover from a B7xx 6982 12X failure.

1. Record the 12X loop number in the first four characters of word 7 of this SRC and perform RIOIP10.
2. Did the 12X loop recover?
   • No: Continue with the next step
   • Yes: Close the problem. This ends the procedure.
3. Work with the customer to determine if an I/O enclosure on the 12X loop has powered down normally.
4. Was an I/O enclosure on the loop powered down normally?
   • No: Go to 6.
   • Yes: The loop remains in a failed state until all I/O enclosures on the loop are powered on and functioning. Work with the customer to determine if all the powered down enclosures on the loop can be powered on. After all enclosures on the loop are powered on, continue with the next step.
5. Did the 12X loop recover?
   • No: Continue with the next step.
   • Yes: Close the problem. This ends the procedure.
6. Search for a serviceable event with a 1xxx xxxx SRC logged at approximately the same time and with one or more FRUs in the same unit as those in the FRU list for the SRC you are currently working.
7. Did you find a serviceable event with a 1xxx xxxx SRC?
   • No: Go to 9
   • Yes: Work to resolve the problem. After you have repaired that error, the 12X loop may be recovered. After you finish working on the problem, return to this procedure and check to determine if correcting that problem also corrected the 12X error. To determine if the 12X loop has recovered, record the 12X loop number in the first four characters of word 7 of this SRC and perform RIOIP10.
8. Did the 12X loop recover?
   • No: Continue with the next step.
   • Yes: Close the problem. This ends the procedure.
9. In the serviceable event view, search for a B700 6981 error logged at approximately the same time and on the same 12X loop (the first four characters of word 7 are the same).
10. Did you find a serviceable event with a B700 6981 SRC at approximately the same time and on the same 12X loop?
    • No: Go to 14.
    • Yes: Work to resolve the problem. After you have repaired that error, the 12X loop may be recovered. After you finish working on the problem, return to this procedure and check to determine if correcting that problem also corrected the 12X error. To determine if the 12X loop has recovered, record the 12X loop number in the first four characters of word 7 of this SRC and perform RIOIP10.
11. Did the 12X loop recover?
    • No: Continue with the next step.
    • Yes: Close the problem. This ends the procedure.
12. Verify that all 12X cables in the loop are connected securely. Attach any cables which are not connected to complete the 12X loop. Did you find any 12X cables to connect?
    • No: Go to 14.
    • Yes: Perform RIOIP10.
13. Did the 12X loop recover?
    • No: Continue with the next step.
    • Yes: Close the problem. This ends the procedure.
14. Using the FRU list that you are working with for this SRC, exchange one FRU at a time. After you exchange each FRU, determine if the loop has recovered. To determine if the 12X loop has recovered, record the 12X loop number in the first four characters of word 7 of this SRC and perform RIOIP10. After the loop recovers or after you have exchanged all the FRUs, continue with the next step. To replace a FRU, see System FRU locations.
15. Did the 12X loop recover?
    • No: Contact your next level of support. This ends the procedure.
    • Yes: Close the problem. This ends the procedure.
