Check for the latest version of SAP OSS Note 757692.
Installation is complete.
Run some comprehensive switchover testing covering all possible failure scenarios. It is important that all
relevant SAP application functions are tested on the switchover nodes. There exist several documents provided
by HP or SAP that can guide you through this process.
IPv6 Specific Installation
Release A.03.00 of SGeSAP/LX now supports IPv6 network configurations in addition to the traditional IPv4
configurations. The cluster nodes will run as a dual network stack configuration - the network interfaces have
IPv6 and IPv4 enabled at the same time.
NOTE: Currently both Oracle and MaxDB only support IPv4 addressing, SAP Netweaver supports both
IPv4 and IPv6.
The perl Socket6 module provides an IPv6 function set for the perl language and is required by the
SGeSAP/LX A.03.00 scripts to work properly in an IPv6 environment.
In the following examples IPv6 address 2001::101:146 will be used for cluster node sap146, IPv6 address
2001::101:147 will be used for node sap147
The SAP SID <SX1> will be used in this configuration
Installation Step: IP1200
Check if the perl-Socket6 module is available on the system by running the command:
rpm -qa|grep perl-Socket6
If the module name is not returned install it if available from the original distribution media If it not available
the perl-Socket6 module can also be downloaded from the following web sites:
