Hot-Pluggable Pci Adapter Removal - IBM pSeries 630 6C4 Service Manual

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.
