Verifying That The Hot-Plug Adapter Tools Are Installed For The Linux Operating System - IBM 9080-HEX Installing

physical volumes accessed by that adapter, then You can take action on the client before you unconfigure
the adapter.
The virtual target devices must be in the define state before the Virtual I/O Server adapter can be
replaced. Do not remove the virtual devices permanently.
Procedure
To prepare the client logical partitions so that you can unconfigure an adapter, complete the following
steps depending on your situation.
Table 2. Situations and steps for preparing the client logical partitions
Situation
You have redundant hardware on the Virtual I/O
Server for the adapter.
HMC-managed systems only: You have redundant
Virtual I/O Server logical partitions that, in
conjunction with virtual client adapters, provide
multiple paths to the physical volume on the client
logical partition.
HMC-managed systems only: You have redundant
Virtual I/O Server logical partitions that, in
conjunction with virtual client adapters, provide
multiple physical volumes that are used to mirror
a volume group.
You do not have redundant Virtual I/O Server
logical partitions.
Verifying that the hot-plug adapter tools are installed for the Linux operating
system
Find information about how to verify that the hot-plug adapter tools are installed on your Linux system so
you can then verify the adapter is installed.
Procedure
1. Enter the following command to verify that the hot-plug adapter tools are installed: rpm -aq | grep
powerpc-utils.
If the command does not list any powerpc-utils packages, the Hot Plug tools are not installed.
2. Enter the following command to ensure that the rpaphp driver is loaded: ls -l /sys/bus/pci/
slots/
The directory should contain data.
• If the directory is empty, the driver is not loaded or the system does not contain hot-plug adapter
slots. The following is an example of the information displayed by this command:

Steps
No action is required on the client logical partition.
No action is required on the client logical partition.
However, path errors might be logged on the client
logical partition.
See the procedures for your client operating
system. For example, for AIX, see Replacing a
disk on the Virtual I/O Server in the Advanced
®
POWER Virtualization Best Practices Redpaper.
The procedure for Linux is similar to this procedure
for AIX.For example, for AIX, see Replacing a
disk on the Virtual I/O Server in the Advanced
Power Virtualization Best Practices Redpaper. The
procedure for Linux is similar to this procedure for
AIX.
Shut down the client logical partition.
