Caveats Send documentation comments to [email protected] Symptom: An IOA flow can take a few seconds to become active in certain events such as host or target port flaps. PLOGIs from the hosts are buffered until the IOA flow becomes active. Once the IOA flow becomes active, a RSCN is sent, which forces the host to perform a PLOGI again. Certain target arrays perform a few back-to-back PLOGIs prior to the flow becoming active, which may cause automatic path recovery to fail. Workaround: This issue is resolved. • CSCti00670 Symptom: The system reboots when IVR fails. Workaround: This issue is resolved. • CSCsx33891 Symptom: In rare circumstances, the SANTap process or SME process might fail on an MDS switch running NX-OS Release 4.1(x) software. If the process fails on an MDS 9222i switch, then a full switch reload might occur. Workaround: This issue is resolved. • CSCtb43279 Symptom: The wwn_manager process might fail after ports are flapped because the internal system manager does not received a heartbeat from the process. Workaround: This issue if resolved. • CSCte93219 Symptom: If you have an MDS 9000 switch running NX-OS Release 5.0(1a) and also running DMM or Secure Erase, when you downgrade to an NX-OS 4.x release, you see the following errors: - Syslog messages display the error string PSS_VERSION_MISMATCH for the configuration of an internal service (ilc_helper) - After the ISSD completes and the switch comes up with the NX-OS 4.x release, an internal process (ilc_helper) fails. Workaround: This issue is resolved. • CSCtg11776 Symptom: On a switch where AAA remote authentication was configured, scheduled jobs started failing approximately 24 to 48 hours after they were configured because the scheduler aaa-authentication command did not appear in the running configuration. Workaround: This issue is resolved. • CSCtg86355 Symptom: Quoted strings are not permitted in a Call Home configuration for the following values: customer ID and site ID. Workaround: This issue is resolved. • CSCth20253 Symptom: The data path processor engine on the MSM-18/4 module occasionally fails after an exchange error occurs between an initiator and target in an IOA cloud. The error occurs because the tape write takes a long time to complete and IOA on the target side MDS 9000 switch tries to abort the exchange. Workaround: This issue is resolved. • CSCth21404 OL-21012-02 Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.0(4) 35
