About Swapping Host Bus Adapters
Swapping brands of host bus adapters (HBA) on a Microsoft Windows 2000 host may have
undesirable side effects. For example, after swapping out one brand of an HBA for another
(including driver installation), WinMgmt.exe might crash repeatedly and appear to be associated
with an error in the Windows Event Log about being unable to retrieve data from the PerfLib
subkey in the Registry. To solve this problem, reinstall the operating system.
“Fork Function Failed” Message on AIX Hosts
If a CIM Extension running on AIX detects low physical or virtual memory while starting, a “Fork
Function Failed” message appears. A CIM Extension on AIX uses additional memory and CPU
resources at start time. If the resources on the AIX machine is already low, you may see the “Fork
Function Failed” message. Depending on the AIX operating system or hardware, the host may crash
after you see this message.
Known Driver Issues
If you are having problems with a driver, keep in mind the following:
• The software requires the driver to have a compliant SNIA HBA API. Emulex driver version 4.21e
does not support the SNIA HBA API.
• If the driver has a compliant SNIA HBA API, make sure the driver is installed correctly.
