Backup SAP HANA via a DDBEA failed

Hello!

Question to someone familiar with DDBEA. Could you please help me to find out what may cause such error?

I'm trying to configure backup of SAP HANA to Data Domain VE via a Dell EMC Data Domain Boost for Enterprise Applications and ProtectPoint Database Application Agent. Its version is 4.5.1.

Following admin guide, I've configured both SAP HANA and DDBEA, but can't make a backup. It fails with following error in SAP HANA:

Could not start backup for system BBB DBC: [447]: backup could not be completed: [110515] Backint missing software version tag

In DDBEA logs there is not much information which could help to identify root cause of a problem.

The only suspicious messages that I've found in LGTOSAPs.debug log are:

(pid = 11321) (11/24/2017 10:33:01 AM) lnm_parms_list_get_type: Entering.

(pid = 11321) (11/24/2017 10:33:01 AM) lnm_parms_list_get_type: Exiting with error:

The name 'data domain client information' does not correspond to a valid LNM parameter.

(pid = 11321) (11/24/2017 10:33:01 AM) lnm_parms_list_check_recognized: Entering.

and

hdbbackint: 11/24/17 10:33:01.498176 Reverse DNS lookup failed for <ip of my SH server>: Name or service not known

but it can be successfully 'nslookup'ed manually.

In hdbbackint<SID>.debug log there are some additional messages. Not sure about them's importance:

11/24/17 10:32:57 hdbbackint: 11/24/17 10:32:57.427161 No access to file /usr/sbin/lcmap: No such file or directory

The only parameters which I've modified in conf file were:

DDBOOST_USER

DEVICE_HOST

DEVICE_PATH

DEBUG_LEVEL

DPRINTF

PARALLELISM

May be I've missed something?

Also, "hdbbackintHANA_..." files which are error logs and usually are created in case of errors aren't created in this case! It's strange!

I very appreciate possible answers/advices! Thank you in advance!

Re: Backup SAP HANA via a DDBEA failed
