Unable to See Path Information

You will not be able to see path information if LUN masking information is missing. To view LUN

masking information, follow the steps described in the section, ”

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 15.

IMPORTANT:

EFC Manager uses the SWAPI connection, preventing other third-party software

from contacting the switch.

Unable to Detect a Host Bus Adapter

The software is unable to detect a host bus adapter if you install its driver before you have

completed installing the Solaris operating system for the first time. For example, you installed the
