Clustered Node Synchronization
1. Repeat the steps in this section for each node of the cluster that is
different from the primary.
2. Logon as root to the primary host and prepare a logon for each of its
backup hosts.
LC030 liveCache installation Step:
Synchronize the /etc/group and /etc/passwd files. The liveCache
installation has created a <lcsid>adm user belonging to the sapsys
group. Make sure the user and group exist on all nodes and that UID and
GID are consistent across the nodes.
LC040 liveCache installation Step:
Synchronize the sql<nn> entries from the /etc/services file between
the nodes to match the entries on the primary node. Usually you will find
service entries for sql6 and sql30.
LC050 liveCache installation Step:
Change the Linux kernel on the backup nodes to meet the SAP liveCache
requirements as specified in the SAP liveCache installation documents.
