Managing Serviceguard Extension for SAP, December 2007
Step-by-Step Cluster Conversion
HP-UX Configuration
Chapter 3130
IS190 Installation Step:
In full CFS environments, this step can be omitted. If CFS is only used
for SAP and not for the database, then the volume group(s) that are
required by the database need to be distributed to all cluster nodes.
Import the shared volume groups using the minor numbers specified in
Table 1 – Instance Specific Volume Groups contained in chapter
“Planning the Storage Layout”.
The whole volume group distribution should be done using the command
line interface. Do not use SAM. SAM will not create minor numbers in
the intended fashion. Specify the device minor numbers explicitly by
creating the group file manually.
On possible failover nodes, for example:
mkdir /dev/vgdb<SID>
mknod /dev/vgdb<SID>/group c 64 0x080000
Now you can use vgimport(1m) with the map file created on the primary
host during Step IS020.
IS210 Installation Step:
Create a local directory for the saposcol temporary data on possible the
backup nodes. For example:
mkdir -p /usr/sap/tmp
IS220 Installation Step:
Create a local mount point for each file system that was specified in
chapter “Planning the Storage Layout to have shared disk” or HA NFS”
access point. Refer to the tables in chapter 2 for Instance, System and
Environment specific volume groups and the corresponding tables that
represent entries for the required database type. Depending on the past
usage of the hosts, some of the directories might already exist.
For non-CFS options only:
su - <sid>adm
mkdir -p /sapmnt/<SID>
mkdir -p /usr/sap/trans
mkdir -p /usr/sap/<SID>/<component><INSTNR>
exit
