📦 version 3.1.3, in opensuse-leap 16.0

💅 cs_precheck_for_hana — the vibe check for your HANA box

ok so you found cs_precheck_for_hana(8) in the ClusterTools2 corner of the manual and you're like "what does this even do" — bestie, same, but I got you. Stick with me 🫶

✨ NAME ✨

cs_precheck_for_hana — checks the pre-requisites for SAP HANA System Replication and for automation with a SLE-HA cluster 🔥

🌸 SYNOPSIS 🌸

cs_precheck_for_hana [OPTION]

🦋 DESCRIPTION 🦋

okay so cs_precheck_for_hana checks whether a Linux system is prepared for running SAP HANA in general. and like, not just that — it also checks the pre-requisites for SAP HANA System Replication automation with a SLE-HA cluster. two-for-one, we love to see it 💅

the check is done according to the concept described in the setup guide SAP HANA System Replication on SLES for SAP Applications.

the way to do it: check all nodes of a cluster, no skipping 🙈. you can totally re-direct the output of cs_precheck_for_hana into a file. and then — plot twist — you can compare the output files from different hosts to make sure all nodes of a cluster are set up identically. this is helpful particularly in scale-out scenarios. iconic, honestly ✨

🎀 OPTIONS 🎀

the 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 💀

  • 0 — successful program execution. slay 🎉
  • >0 — usage, syntax or execution errors. not the vibe 😭

🌈 EXAMPLES 🌈

  • Show help.
# cs_precheck_for_hana -h
  • Check for basic OS pre-requisites needed to install SAP HANA. Items needed to set up automation for System Replication are also checked.
# cs_precheck_for_hana -b
  • Find differences between nodep and nodeq.
# cs_precheck_for_hana -b >nodeq.precheck.txt 2>/dev/null
# ssh root@nodep "cs_precheck_for_hana -b 2>/dev/null" >nodep.precheck.txt
# diff --suppress-common-lines nodeq.precheck.txt nodep.precheck.txt
  • Include findings of cs_precheck_for_hana with supportconfig file.
# sed -i s/#precheck_for_hana/precheck_for_hana/ /etc/ClusterTools2/supportconfig_plugins
# supportconfig

🍓 FILES 🍓

  • /usr/sbin/cs_precheck_for_hana — the program itself. main character energy, obviously 👑
  • /etc/ClusterTools2/cs_precheck_for_hana, /etc/ClusterTools2/cs_show_supportconfig — the configuration files.

🧚 BUGS 🧚

heads up bestie, real talk: the formatting and content of this script's output will change, since this script is under development. no cap. also, checks specific to the HANA application are currently not implemented — so don't come for it, it's literally still growing 😭

feedback is welcome, please mail to feedback@suse.com 💌
