无法使用 Azure 站点恢复连接到 SAP HANA 备份中的“AAD1”服务

Question

I am using the SAP Hana 2.0 & trying to implement the SAP HANA backup using the Azure Recovery vault.

For that, I have to run the file "msawb-plugin-config-com-sap-hana.sh". So it was showing the error as Failed to connect AAD1 service.

Anyone knows the issue. please resolve.

Answer 1

I am facing the same issue too. I'm working with SAP Hana running on a SUSE 15sp1 Azure VM, with network connectivity established by the use of NSG service tags as from https://docs.microsoft.com/en-us/azure/backup/backup-azure-sap-hana-database .

Looking inside the script I noticed that a curl request is used to run connectivity checks

curl --silent --output /dev/null --location --request "HEAD" "https://login.windows.net/" --write-out "%{http_code}\n"

If I run curl manually, changing the options in order to make it display the whole of the command output, it returns the following:

Warning: Setting custom HTTP method to HEAD with -X/--request may not work the
Warning: way you want. Consider using -I/--head instead.
curl: (56) OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104

This error is reported as a closed issue on the curl Github repo ( https://github.com/curl/curl/issues/4409 ). It looks like if it would be solved by subsequent curl release.

Mine is 7.60.0. Latest is 7.73.0. Unfortunately 7.60 seems to be the latest available in SUSE repos and I do not want to intall not officially approved packages on a production system.

So in my case the only way out would be to run the script with the --skip-network-checks parameter.

We just fixed this issue in the latest version of script updated yesterday. Can you please re-check with the latest version?
