1.7.3 Configuring the IBM 2105 for clustering
This section describes how to configure a Hewlett Packard host system for
clustering.
The steps to configure MC/ServiceGuard with the IBM 2105 are the same as the
steps in the Hewlett Packard high availability documentation located at the
following Web site:
www.docs.hp.com/hpux/ha/index.html
If you are not familiar with the steps in the Hewlett Packard documentation, IBM
recommends that the system administrator attend the Hewlett Packard class
about high availability features.
After you configure your host for normal operating system access, the 2105 acts
as a normal disk device in the MC/ServiceGuard configuration. IBM recommends
that you create volume groups that contain the volumes using the Hewlett
Packard logical volume manager. This method of disk management is more
reliable, easier, and more flexible to manage than whole-disk management
techniques.
Creating volume groups also allows the implementation of PV-Links, Hewlett
Packard's built-in multipathing software, for highly available disks such as the
IBM 2105. To establish PV-Links, perform the following steps:
1. Create the volume group, using the path to the volumes that you want as the
primary path to the data.
2. Extend the volume group with the path to the volumes intended as alternate
paths. The logical volume manager reads the label on the disk and knows
that it is an alternate path to one of the volumes in the group. The logical
volume manager labels the volume. For example, if a host has access to a
volume on a 2105 with the device nodes c2t0d0 and c3t0d0, you can use the
c2 path as primary and create the volume group using only the c2t0d0 path.
