Replacing Fibre Channel adapters using hot swap
When hot swapping Fibre Channel adapters, be aware that device-related software for the storage
devices might have additional devices (for example, the dar device associated with the FAStT or DS4800)
that need to be removed. Refer to specific storage device documentation for information about how to
remove these additional devices.
The adapter has a unique worldwide port name (WWPN). Check the zoning and LUN assignments to
ensure that the new adapter functions as expected.
Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. For information about operating system and partition requirements, see one of the following
topics:
• The latest version of enabling libraries and utilities can be downloaded from Fix Central (http://
www.ibm.com/support/fixcentral/).
• Power Systems Prerequisites (http://www14.software.ibm.com/support/customercare/iprt/home).
• IBM SSIC (System Storage Interoperation Center) (http://www-03.ibm.com/systems/support/storage/
ssic/interoperability.wss).
• The latest version of the device driver or IBM Power RAID adapter utilities (iprutils) can be downloaded
from the IBM Service and Productivity Tools website (http://www14.software.ibm.com/webapp/
set2/sas/f/lopdiags/home.html).
• For support details, see the Linux Alert website (http://www14.software.ibm.com/webapp/set2/sas/f/
