Caveats Send documentation comments to [email protected] • CSCsg49151 Symptom: If you bring up more than one link at a time between two VSANs that have overlapping domains and at least one of the switches is SDV enabled, one link will become isolated. The other links will come up, even though the domains are overlapping. In addition, the SDV virtual domains will change, causing traffic disruption on all devices associated with their old value. 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.
