Step by Step Installation of SGeSAP on Integrity Linux for SAP WAS Central Instances
Linux Configuration
Chapter 2 55
IS370 Installation Step:
If you need to establish frontend and server LANs to separate network
traffic, be sure to add static routing entries to the internet routing
configurations of /etc/sysconfig/network/routing file. Route all
relocatable client LAN addresses to the local server LAN addresses. For
example, a two package concept would result in two entries:
<relocdb> <relocdb_s> 255.255.255.255
<relocci> <relocci_s> 255.255.255.255
IS380 Installation Step:
Comment out the references to any filesystem that is identified as shared
in section “Planning the LVM layout for Clustered SAP Environments”
from /etc/fstab.
IS390 Installation Step:
Make sure that the content of /etc/fstab is not recreated during
system reboot.
The file /etc/rc.d/boot.vginit is executed during reboot by default.
It should not perform any action for shared volume groups.
IS400 Installation Step:
The HA NFS file system export and crossmounting is realized using the
Linux automounter. It is required to use autofs version 4.
This can be done by (re)installing the corresponding rpm package from
the distribution or Service Pack images. For example:
rpm -U autofs4-4.1.3-1.8.ia64.rpm
Uncomment the following line in /etc/modprobe.conf:
alias autofs autofs4
Then reload the autofs4 kernel module using modprobe(8m) and restart
the automounter process in /etc/init.d/autofs. Also check that the
automounter is configured as part of the system startup.
IS410 Installation Step:
Add the following entry to your /etc/auto.master file:
/import /etc/auto.import nfsvers=3
The use of NFS version 3 is required.
