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 55.
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
cfgadmn command makes the software realize the drive has been removed. Refer to the
documentation that shipped with the Solaris operating system for more information about the
cfgadm command.
Unable to Obtain Information from a CLARiiON Storage System
If you are having difficulty obtaining topology information or element details from a CLARiiON
storage system, the NaviCLI might have timed out as a result of the service processor being under a
heavy load. The management server uses the NaviCLI to communicate with the CLARiiON storage
system. This situation has been seen in the field when the service processor is running more than
35,000 IOPS (IOs/Sec).
Try obtaining Discovery Data Collection/Get Details from a CLARiiON storage system when the
service processor is not under such a heavy load.
