RMAN restore failing in another environment

Question

Hi,
I am facing a problem. I have to restore a database backup from production to Integration
environment. In Production, it is RAC db and RMAN and Veritas Net backup taking the backups.
In Integration Environment also we have the same setup.
So the steps I have done so far is:
1.Have the export of RMAN catalog schema from production and imported in RMAN server in Integration
Environment.#
2. UNIX admins put and mounts the TAPE in tape library.
3. Set the environment for new db in oratab file.
4. connected to target and RMAN.
5. startup nomount from RMAN.
6.executed the following commands
RMAN> run {
2> allocate channel t1 type sbt;
3> validate backupset 2805233;
4> }
released channel: ORA_DISK_1
allocated channel: t1
channel t1: sid=317 devtype=SBT_TAPE
channel t1: VERITAS NetBackup for Oracle - Release 6.0 (2005090703)
channel t1: starting validation of datafile backupset
channel t1: reading from backup piece db_11192_1_651890513
released channel: t1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of validate command on t1 channel at 06/05/2008 12:23:51
ORA-19870: error reading backup piece db_11192_1_651890513
ORA-19507: failed to retrieve sequential file, handle=”db_11192_1_651890513″, parms=”"
ORA-27029: skgfrtrv: sbtrestore returned error
ORA-19511: Error received from media manager layer, error text:
Failed to process backup file
RMAN>
I’ve got the backupset key from RMAN catalog, but it is failing to validate the backup set.
And also all the subsequent attempts to restore spfile/controlfile/database are failing.
Now, I have been advised by Oracle that this is the problem with Media Manager and I have to contact
them, unfortunately I dont have support service from Veritas.
Could any of you guys please advise, do we need to do any other configrations in net back to Identify
the tapes from foreigen envirnment/ do we need to pass any more paramters from RMAN to see the newly
mounted TAPS?
Your help will be highly appreciated.
Thanks and Regards,
Zach

Zach,
Can you certain tests for me ?
1)
Lets assume some terms here
a) origclient = your target host
b) altclient = your destination host
c)media manager server = host that contains your netbackup master software
Can you goto altclient and first check if your altclient is able to browse the backups generated by the origclient
$NETBACKUP_HOME/bin/bplist -C <origClient> -t 4 -l -R /
2) Have you configured your ORACLE_HOME on the destination to link one of its libraries to the Media Management software ?
goto $ORACLE_HOME/lib
ls -lrt libobk.sl . This file should be a softlink to $NETBACKUP_HOME/bin/libobk.sl64
3) Please use the SEND command in your RMAN restore scripts. You need so specify the NB_ORA_SERV (your media management master server) and NB_ORA_CLIENT (your origclient host)
SEND 'NB_ORA_SERV=<media manager server>, NB_ORA_CLIENT=<origclient>';
4) Make sure your $NETBACKUP_HOME/bp.conf has the required parameters for client and server. client will be your origclient and server will be your media management server that has the netbackup master software
