If you need to replace an MSM-18/4 module with another MSM-18/4 module
In the existing MDS 9000 Family platform, a module can be replaced with another module and there is
no change in configuration. In Cisco SME, due to security reasons, when an MSM-18/4 module is
configured as part of a cluster, it cannot be replaced with another MSM-18/4 module otherwise the Cisco
SME interface will come up in an inactive state. The correct procedure is to remove the Cisco SME
interface from the cluster and re-add the interface back into the cluster.
If a Cisco SME cluster is not successfully created
There are three main reasons that a Cisco SME cluster may not be successfully created:
SSH must be enabled on every switch that is part of a Cisco SME cluster.
•
Note
If the Cisco SME switches are managed using their IP addresses (instead of host names or FQDN),
•
the entry "sme.useIP=true" must be set in the smeserver.properties file. Be sure to restart the Fabric
Manager Server after modifying the smeserver.properties file.
• The DNS server must be configured.
Sometimes, improperly configured personal firewall software (running on Cisco Fabric Manager
•
Server) may also cause a created SME cluster to stay in the "pending" state. Be sure to create proper
firewall rules to allow necessary traffic between Fabric Manager Server/Fabric Manager web
client/switches.
A Cisco SME interface does not come up in a cluster
If a Cisco SME interface does not come up, this can be due to the following:
• A Cisco SME license is not installed or the license has expired.
• An MSM-18/4 module has been replaced after the Cisco SME interface has been configured.
• The copy running-config startup-config command was not entered after adding or deleting a Cisco
SME interface from a cluster or before rebooting the switch.
For the second and third scenarios, you must first remove and re-add the interface to the cluster and then
enter the copy running-config startup-config command.
When selecting paths, a "no paths found" message is displayed
A tape library controller or robot can be shown as a target in the Select Tape Drives wizard. If you select
the controller or robot as a target, a "no paths found" message is displayed. You will need to verify
whether or not the selected target is a controller or robot.
When the "no paths found" message is displayed, enter the show tech and show tech-support sme
command.
Newly added tape drives are not showing in a cluster
If you add new tape drives as LUNs to a tape library after Cisco SME has already discovered available
tape drives, a rescan is required from the host to discover the new LUNs.
Cisco MDS 9000 Family Storage Media Encryption Configuration Guide
9-8
Only SSH/dsa or SSH/rsa are supported for Cisco SME cluster configurations using Fabric
Manager Web Client. SSH/rsa1 is not supported for SME cluster config via FM web client
in 3.2.2 (release with SME feature). It may (or may not) be supported in future releases.
