Credential validations fail during instance registration even though credentials appeared to be correct
Description:
SAP HANA instance credential validation requires access or connection to the NetBackup clients or SAP HANA database servers and login to the SAP HANA SYSTEMDB database.
When manually creating the SAP instance in NetBackup, the host name, NetBackup client name and NetBackup host name may not match.
Solution or workaround:
Ensure that the host names specified in the SAP HANA instance matches with the NetBackup host name or client name and there are no network host name resolution issues.
Make sure the primary server can connect to the target SAP HANA clients and the credentials being used are correct.
Use NetBackup tool to test connectivity within NetBackup hosts:
bptestbpcd -host <sap host name> -bpclntcmd_test -M <Primary server name> - verbose
Make sure the SAP HANA database server instance is running and test login using the same credentials like the following command:
hdbsql -n <host name> -i <instance#> -u SYSTEM -p <pw> -d SYSTEMDB
