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.
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 McDATA switch,
other management servers and third-party software are not able to communicate with the switch
using SWAPI.
Use Enterprise Fabric Connectivity (EFC) Manager to communicate with the McDATA switch. EFC
Manager versions 7.0 and later can communicate with the management server and the switch. This
configuration lets multiple instances of the management server or other clients contact EFC
Manager, which in turn provides information about the switch. To communicate with the EFC
Manager, discover the McDATA switches as described in ”Discovering NAS Devices, Tape Libraries,
Switches and Storage Systems” on page 17.
