Restoration problem

Question

Hi
We are in the process of setting DR for our production environment. We are using legato tape backup to restore the DB.
The DB was started in nomount and trying to restore controlfile from the Tape backup. We use following command to restore the controlfile.
run
allocate channel ch1 type 'sbt_tape';
restore controlfile from autobackup;
release channel ch1;
But it gives error that
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of allocate command on ch1 channel at 07/13/2010 13:38:22
ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27211: Failed to load Media Management Library
Additional information: 2
The same problem I had while configuring legato rman backup using tape. That time I linked the library file as oracle user and it was resolved.
Linked file: ln -s /usr/lib/libnwora.so /oracle/ABP/102_64/lib/libobk.so
I tried the samething in our restoration also. But still the error exists.
Could you please guide us on this.
