Caveats Send documentation comments to [email protected] Workaround: Bring up multiple links between two switches one at a time. Verify that the first link came up correctly before attempting to bring up the next link. If the first link fails to come up because of a domain ID overlap, resolve the domain conflict and then try again to bring up the links. • CSCsi72048 Symptom: FCIP links may fail on an MDS 9216i switch that has compression set to auto when the other end of the FCIP link is terminated by an IPS-8 module. You may see the following message in the logs: %IPS_SB_MGR-SLOT1-3-CRYPTO_FAILURE: Heartbeat failure in encryption engine (error 0x1) %ETHPORT-5-IF_DOWN_SOFTWARE_FAILURE: Interface GigabitEthernet1/1 is down (Port software failure) %PORT-5-IF_DOWN_SOFTWARE_FAILURE: %$VSAN 1%$ Interface fcip99 is down (Port software failure) Workaround: If both ends of an FCIP link are not on an MPS-14/2 module, do not use mode 1 and auto. • CSCsk43922 Symptom: A data path processor (DPP) might fail on an MDS switch running SSI Release 3.2(1) on the SSM. The failure occurs after several days of running traffic when a misbehaving target sends unexpected frames well after the response has already been received from the same target. Workaround: None. • CSCsk49029 Symptom: If there is a request to export a domain while the same domain is being cleaned up, domain entries might not be programmed. As a result, communication between IVR devices might not occur. Workaround: Because the programming request was lost, the only way to retrigger the programming is to withdraw the domain and refresh IVR. Follow these steps: 1. Identify domains with problem using the show ivr internal dep command. switch# show ivr internal dep Internal information for DEP FSM vsan domain nh status sync_status req i/f 101 0x61(97) 1001 ALL_DONE OXID|FCID_RW 0 [ fc3/2 ] 102 0x62(98) 1002 ALL_DONE OXID|FCID_RW 0 [ fc3/5 ] 1001 0x9e(158) 101 NONE OXID|FCID_RW 0 [ fc2/16 ] 1002 0x98(152) 102 ALL_DONE OXID|FCID_RW 0 [ fc9/10] Number of DEP entries : 4 After waiting for a few minutes for IVR to stabilize, if the status column for the {VSAN, domain} combination is NONE, then this problem has occurred the switch. 2. Withdraw the troubled domains using the ivr withdraw domain domain vsan vsan-id command. 3. Readvertise the withdrawn domains using the ivr refresh command. • CSCsk49634 Symptom: In rare cases, an FCIP link might flap on a network with high latency and a consistently high loss rate. Workaround: None. OL-14116-10 Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.3(2) 45
