Hot-Pluggable PCI Adapter Removal
Note: Removing a hot-pluggable PCI adapter requires the system administrator to take
the PCI adapter offline before performing any PCI adapter hot-plug procedures.
Before taking an adapter offline, the devices attached to the adapter must also
be taken offline. This action prevents a service representative or user from
causing an unexpected outage for system users.
For additional information about taking an adapter offline or removing it from the
system configuration, see the
AIX System Management Guide: Operating
System and Devices
.
Documentation for the AIX operating system is available from the IBM Eserver
pSeries Information Center at
http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base. Select AIX
documentation. The
AIX Documentation
CD contains the base set of
publications for the operating system, including system-management and
end-user documentation.
This publication is also contained on the AIX Documentation CD. The
documentation is made accessible by loading the documentation CD onto the
hard disk or by mounting the CD in the CD-ROM drive.
