some instances, the API of the Brocade switch has been known to hang. Rebooting the switch clears the switch of the API hang.

Incorrect Topology Sometimes Displayed for CNT Switches

The CNT SMI-S provider for CNT switches does not return the correct topology information when more than one fabric is managed by the same InVSN™ Storage Network Manager. McDATA, which completed its acquisition of CNT in the summer of 2005, has been made aware of this issue.

Device Locking Mechanism for Brocade Element Manager Query/Reconfiguration

Please keep in mind that the configuration for Brocade switches is locked while getting all details for elements in a zones. The software ensures that each CIM query locks out any reconfiguration. For example, if you are getting details for elements in all zones, you cannot add a new Brocade switch while you are doing it (the discovery or configuration process waits until the collection of details is finished before proceeding). However, simultaneous CIM queries do not lock each other out.

A Discovered Sun StorEdge A5000 JBOD Does Not Display Its WWN Properly

Although full monitoring and management support is available only to those devices for which there is a provider, the software's topology displays other devices found on your storage area network (SAN) to give you a more complete view. However, because these devices do not have a provider, only basic information is returned. In some cases, as with the Sun StorEdge A5000 JBOD (just a bunch of disks), the Worldwide Name (WWN) presented and reported to the management server may be different from the official WWN of the device, as the management server reports the WWN of the port connected to the fabric.

Sun 6920 Storage Systems: “ReplicatorSQLException: Database create error”

During Discovery Data Collection

While performing a Discovery Data Collection, the Sun 6920 provider will return the error “ReplicatorSQLException: Database create error” under certain circumstances. This error appears in the management server logs but can be safely ignored. Sun Microsystems is aware of this issue.

Mirrored Volumes Cannot Be Provisioned on Sun 6920 Storage Systems

Mirrored volumes are not represented properly by the management server. You cannot use the management server to provision mirrored volumes on Sun 6920 storage system.

Unable to Monitor McDATA Switches

McDATA switches use the Fibre Channel Switch Application Programming Interface (SWAPI) to communicate with devices on the network. The McDATA switches allow only one SWAPI connection at a time. For example, if the management server discovers the IP address of the
