Linux OS checks for SAP HANA environments - SLES,RHEL for Intel x64 and IBM Power

FAQ

Q: Does it work on all linux versions - independend from distributions, kernel, filesystem, hana version?
A: Yes, checks themselves will verify if they are applicable for environment. However, checks are not complete, eg. filesystems/HANA specifics are not included so far.

Q: Does it change anything on the system?
A: No, scripts only read data. Nothing is changed or written.

Q: Are there any restrictions attention should be paid to?
A: Some checks require root permission in order to read certain kernel parameter values. The check suite itself could run as non-root user, but root required checks would be skipped.

How to run

as root user - extract scripts to Linux server & run saphana-check.sh

• download release

• install rpm (installed to /opt/sap/saphana-checks)

  rpm -Uvh saphana-checks-*.rpm

• just run it or redirect output:

  /opt/sap/saphana-checks/bin/saphana-check.sh
  /opt/sap/saphana-checks/bin/saphana-check.sh 2>&1 | tee -a $(hostname)_SHC.txt
