NAME¶

cs_precheck_for_hana - check pre-requisites for SAP HANA System Replication and automation with SLE-HA cluster

SYNOPSIS¶

cs_precheck_for_hana [OPTION]

DESCRIPTION¶

cs_precheck_for_hana checks if a Linux system is prepared for running SAP HANA in general. It also checks pre-requisites for SAP HANA System Replication automation with a SLE-HA cluster. The check is done according to the concept described in the setup guide SAP HANA System Replication on SLES for SAP Applications .
All nodes of a cluster should be checked. The output of cs_precheck_for_hana could be re-directed into a file. Output files from different hosts might be compared to ensure all nodes of a cluster are set up identically. This is helpful particularly in scale-out scenarios.

OPTIONS¶

Global options are:

--help show help information.

--version show version.

--writecfg show some internal variables.

--base show basic OS configuration, related to SAP HANA and its System Replication.

--apps show basic HANA application configuration, and more specific related OS settings.

EXIT STATUS¶

# diff --suppress-common-lines nodeq.precheck.txt nodep.precheck.txt

* Include findings of cs_precheck_for_hana with supportconfig file.
