PowerPath for UNIX Installation and Administration Guide
PowerPath in a Cluster Environment
Editing main.cf to
Include EMCTypes.cf
Edit the /etc/VRTSvcs/conf/config/main.cf file on one node. The
changes are propagated to the other nodes in the cluster when you
start VCS on those nodes.
You do not need to perform this procedure if GeoSpan 2.0 is installed on the
host.
To edit the main.cf file:
1. Verify that the PowerPath Volume Manager VCS Agent is
installed on the host. Enter:
pkginfo -l EMCvg
2. Save the current /etc/VRTSvcs/conf/config/main.cf file to a
backup location. For example, enter:
cp /etc/VRTSvcs/conf/config/main.cf /etc/VRTSvcs/conf/config/main.cf.orig
3. Add the following line to the beginning of
/etc/VRTSvcs/conf/config/main.cf:
include "EMCTypes.cf"
4. Verify that there are no errors in the edited main.cf file. Enter:
hacf -verify config
If the verification is successful, no output is displayed. Otherwise,
note the error and correct it in the
main.cf file.
