Cannot perform an SAP backup with brbackup

Hello,

I am posting this question as the SAP administrator of our company, who has purchased an EMC Data Domain in order to use it as

a storage for backups, i.e. our SAP backups are being stored there as well.

There is a Data Boost library, which can be used to simulate a tape device and we are using the SBT_TAPE device to take backups.

This has already been configured successfully for 6 Solaris 10 x86 zones and 7 SAP instances. Now I have tried to set it up on another

Solaris zone, using an already established procedure, which is proven to work, but this time it fails miserably and since yesterday

several people have been trying to solve the problem, and still nothing. We are facing the following error:

RMAN> 2> 3> 4> 5> 6> 7> 8> 9> 10> 11> 12> 13> 14>

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03009: failure of allocate command on sbt_1 channel at 11/26/2014 16:19:46

ORA-19554: error allocating device, device type: SBT_TAPE, device name:

ORA-27211: Failed to load Media Management Library

Additional information: 3977

The installation of the libraries using install.sh went flawlessly. I even stopped everything, rebooted the zone and reinstalled again, in

order to be sure that everything is clean. I have used BRBACKUP tracing and still no additional hints to the error. Just from the BRBACKUP

trace I could see, that the correct directory $ORACLE_HOME/lib is present in the LD_LIBRARY_PATH variable, used by BRTOOLS.

The library files are present, with correct ownership and permissions, everything is setup fine, just only on this zone it is failing.

I also went through all the troubleshooting step in the documentation: h10683-dd-boost-oracle-rman-tech-review-wp.pdf. Everything looks

fine, running ldd shows that all the libraries are present and can be resolved...

I have also compared the environment variables of the ora users between the non-working zone and a working zone, also the RMAN

parameters, using the show all; command, it is all identical and I am really totally out of ideas!

PLEASE kindly help me to resolve this issue, it is a show stopper for a long chain of further activities... Thank you!
