Managing Serviceguard Extension for SAP, December 2007

SAP Master Data Management (MDM)
Installation and Configuration Considerations
Chapter 5248
MDM010 Setup Step:
Add MDM virtual IP addresses and hostnames to /etc/hosts.
The database will be accessible under the 172.16.11.97/mdbreloc
virtual IP address/hostname, the MDS component under the
172.16.11.95/mdsreloc virtual IP address/hostname and the MDM NFS
files systems under 172.16.11.95/mdmnfsreloc virtual IP
address/hostname. MDIS and MDSS do not require a separate virtual
address. Both always connect to the virtual IP address of the MDS server.
A virtual IP address will be enabled on the cluster node where the
corresponding Serviceguard package is started and disabled when the
package is stopped.
/etc/hosts
----------
172.16.11.95 mdsreloc # MDM reloc address for MDS
172.16.11.96 mdmnfsreloc # MDM reloc address for NFS
172.16.11.97 mdbreloc # MDM reloc address for DB
172.16.11.98 clunode1 # cluster node 1
172.16.11.99 clunode2 # cluster node 2
MDM020 Setup Step:
Run ioscan and insf to probe/install new disk devices.
Scan for new disk devices on the first cluster node (clunode1). In the
following example, the storage used for this configuration is EVA /
HSV200 based fibre storage and was already initialized.
