Installing PowerPath

For example:

local0.Warn /dev/sysmsg

The separator between localX.Warn and /dev/sysmsg must be a tab character.

2.Set the RAD_LOG_FACILITY environment variable to

LOG_LOCALX, where X is the number you used in the local setting of the /etc/syslog.conf file.

For example, for csh, enter:

setenv RAD_LOG_FACILITY LOG_LOCAL0

For sh, enter:

RAD_LOG_FACILITY=LOG_LOCAL0; export RAD_LOG_FACILITY

Prepare For a Clustered Environment

If you are installing PowerPath in a clustered environment:

Prepare the cluster environment.

Refer to Chapter 2, PowerPath in a Cluster Environment, for information on installing PowerPath in a new or existing cluster.

Find a major number that can be assigned to the PowerPath driver, emcp, on every host in the cluster. This must be a unique number that is unused by any host in the cluster. The installation will prompt you for this number.

Setting the major number is necessary only if you intend to use NFS mounted file systems on PowerPath Volume Manager volumes in your cluster. For more information, refer to Setting Major and Minor Numbers on page 2-13.

To find a unique major number:

1.Enter the following command on every host in the cluster: sort -n +1 /etc/name_to_major

2.Note the highest major number on every node.

Then, when the installation prompts for a major number, use a number that is higher than all of these.
