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 Filers, 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 HBA drives too early when you used JumpStart to install Solaris. The best way to install the HBA driver is to install it after Solaris has been installed and is running.

Navigation Tab Displays Removed Drives as Disk Drives

If you remove an internal disk from a Solaris host and do not enter the cfgadm command, the Navigation tab displays the empty slot as DiskDrives_XXXXX after getting element details. The
