Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsq08896 Symptom: In rare cases, an FCIP link may flap periodically.When you issue the show port internal link-events command from the associated module, you may see a Loss of Sync reason in the output which might indicate this issue. Workaround: This issue is resolved.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsq70353 Symptom: The QOS component on a standby Supervisor module looses a small amount of memory during every port flap. This loss increases over time and may result in the QOS component restarting on the standby Supervisor module. This affects standby Supervisor modules on MDS 9500 series switches only.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsq37212 Symptom: The show tech-support details command leaves residual files in the /tmp directory on the MSM-18/4 module if the SME feature is not enabled. This exhausts the file system limit for open files after issuing the the show tech-support details command more than 117 times and causes a module reload. Workaround: This issue is resolved.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • 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.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsk49634 Symptom: In rare cases, an FCIP link might flap on a network with high latency and a consistently high loss rate. Workaround: None. • CSCsk51193 Symptom: Following an upgrade to Cisco MDS SAN-OS Release 3.2(1) on a Cisco MDS 9124 switch, an interface is shown as up, but there is no FLOGI information for the port in the FLOGI database. Workaround: Set the port mode to F.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m If an upgrade is attempted when such active configuration is present, the switch will go into a disruptive upgrade. Workaround: None. On the MDS 9222i module, an upgrade from SAN-OS Release 3.2(x) to Release 3.3(1a) is not supported if there is a Cisco SME or Cisco DMM configuration in the fabric for hosts and targets attached to the MDS 9222i module.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsg19148 Symptom: Time zone changes that are executed on an MDS switch do not take effect on the 12-port, 24-port, and 48 port 1-Gbps/2-Gbps/4-Gbps Fibre Channel modules, and on the 4-port 10-Gbps module. This issue occurs in SAN-OS Releases 3.0(1), 3.0(2), 3.0(2a), and 3.0(3).
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsk35951 Symptom: In a configuration with a PortChannel with FCIP members and write acceleration in use, if IVR NAT is enabled on one end of the PortChannel and not enabled on the other end, then traffic over the FCIP tunnel might fail. Workaround: Enable IVR NAT on both ends of the PortChannel or disable it on both ends.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsk95241 Symptom: If you use JDK instead of JRE on Solaris, you might encounter a problem trying to install Device Manager from a web browser. This can happen because the installer heap limit of 256 MB is not sufficient. Workaround: If you have this problem, save the jnlp link as file, increase the heap limit to 512 MB, and run javaws element-manager.jnlp at the shell prompt.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsl42571 Symptom: SNMP timeouts occur when a AAA user ages out. By design, a AAA user is aged out every hour on a switch for security reasons. If a large fabric is discovered using a AAA user and a Performance Monitoring (PM) collection is added for such a fabric, a number of SNMP requests (related to the discovery or PM statistics collection) could time out.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsm54071 Symptom: Data Virtual Targets (DVTs) are lost after a downgrade from Release 3.3(1) to earlier releases Workaround: None. • CSCsm63010 Symptom: In SAN-OS Release 3.2(3a) or earlier, Cisco DMM did not include Method1 and Method2 DMM jobs. In those releases, stored configurations were treated implicitly as Method1 DMM jobs. Configurations now stored by SAN-OS Release 3.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Workaround: Before you install Fabric Manager, Fabric Manager Server, and Device Manager when using Microsoft Terminal Server in Application mode, you must install the application for global use. This is required when a Service is installed and invoked, and when creating a local dbadmin user. To activate this setting, do the following: 1.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCso49196 Symptom: During an upgrade from SAN-OS Release 3.2(3a) to Release 3.3(1a), when a switchover occurs to the Supervisor running Release 3.3(1a), Cisco SME traffic flows for hosts that are not connected locally to the switch that is getting upgraded, may get flapped for a very short time. This can also occur during a switchover to a Supervisor running Release 3.3(1a). Workaround: None.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsk43927 Symptom: The following Fabric Manager client components that use SSH and Telnet do not work well with NAT: • DMM storage job creation • Cisco SAN-OS software upgrade • Zone activation Workaround: None. • CSCsk90998 Symptom: The signal loss counters in the output of the show interface fcx/y command are not incremented.
