Table 2. Situations and steps for preparing the client logical partitions (continued)
Situation
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 PCI tools are installed for Linux

Find information about using the hot-plug PCI tools for a PCI adapter installed in a system with a Linux
operating system.
Procedure
1. Enter the following command to verify that the hot-plug PCI tools are installed: rpm -aq | grep
powerpc-utils.
If the command does not list any powerpc-utils packages, the PCI 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 PCI slots.
The following is an example of the information displayed by this command:
drwxr-xr-x 15 root root 0 Feb 16 23:31 .
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
drwxr-xr-x
• If the directory does not exist, run the following command to mount the filesystem: mount -t
sysfs sysfs /sys
3. Ensure the following tools are available in the /usr/sbin directory.
• lsslot
• drmgr -c pci

Steps
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.
For systems that are managed by the HMC, see
