Managing Serviceguard Extension for SAP Version A.06.00 for Linux, December 2012

Intermediate synchronization and verification of virtual hosts
To synchronize virtual hosts:
1. Ensure that all the virtual hosts that are used later in the SAP installation and the NFS toolkit
package setup are added to the /etc/hosts. If a name resolver is used instead of
/etc/hosts, then ensure that all the virtual hosts resolve correctly.
2. Verify the order and entries for the host name lookups in the /etc/nsswitch.conf.
For example:
hosts: files dns
Verification step(s):
To verify whether the name is resolved with the same IP address, ping the virtual host
on all the nodes.
ping nfsreloc
PING nfsreloc (192.168.100.99) 56(84) bytes of data.
64 bytes from saplx-0-31 (192.168.100.99): icmp_seq=1 ttl=64 time=0.113 ms
64 bytes from saplx-0-31 (192.168.100.99): icmp_seq=2 ttl=64 time=0.070 ms
Intermediate synchronization and verification of mount points
The procedure for synchronizing mount points are as follows:
1. Ensure that all the file system mount points for this package are created on all the cluster nodes
as specified in the prerequisites.
Verification step(s):
For example:
Run the cd /sapmnt/C11 command on all the nodes, and test for availability.
Infrastructure setup for NFS toolkit (Phase 1a)
If a dedicated NFS toolkit package sapnfs for SAP is planned for the installation, this must be
setup at a veryan early stage. You can create the package using either the Serviceguard Manager
or the CLI interface.
NOTE: If a common sapnfs package already exists, it can be extended by the new volume
groups, file systems, and exports. Mount points for the directories that are used by the NFS toolkit
package and the automount subsystem must exist as part of the prerequisites. If the mount points
do not exist, you must create it depending on the requirement.
For example:
mkdir -p /export/sapmnt/C11
Creating NFS Toolkit package using Serviceguard Manager
NOTE: To create a package you can use either Serviceguard Manager GUI or the CLI. This
section describes GUI steps and the CLI steps are described in the “Creating NFS toolkit package
using Serviceguard CLI” (page 51) section.
The Serviceguard Manager GUI can be used to setup, verify and apply SAP sapnfs packages.
To create an NFS toolkit package:
1. From the Serviceguard Manager Main page, click Configuration in the menu toolbar, then
select Create a Modular Package from the drop down menu.
2. If toolkits are installed, a Toolkits Selection screen for selecting toolkits appears. Click yes
following the question Do you want to use a toolkit?
