Managing Serviceguard Extension for SAP on Linux (IA64 Integrity and x86_64), February 2008

Step-by-Step Cluster Conversion
Linux Configuration
Chapter 3 113
IS010 Installation Step:
Make sure that the volume group layout is compliant with the needs of
the Serviceguard package(s) as specified in the tables of Section
"Planning a File System Layout for SAP in a Serviceguard/LX Cluster
Environment.” All directories that are labeled shared in these tables
need to reside on logical volumes on a shared external storage system.
The recommended separation in different volume groups can also be
taken from these tables.
IS030 Installation Step:
Comment out the references to any file system that classified as a
SHARED in Chapter 2 of this manual from the /etc/fstab.
IS031 Installation Step:
If /usr/sap/<SID> is a mountpoint that contains the Central Instance
directory DVEBMGS<INSTNR>, you have to move some files to a local logical
volume and change the mountpoint. For example:
mkdir /usr/sap/<SID>.new
cd /usr/sap/<SID>
df .
# Remember the file system column.
# It will be referred to as <dev_path> later.
find . -depth -print|cpio -pd
/usr/sap/<SID>.new
cd /
unmount /usr/sap/<SID>
