Checking status of archivelogs - Data Protector

Hi Expects,

We have restored the database and recovery done. We would like to check the status of few archivelogs whether they are available. We used the same below commands for restore and recovery.But the list command fails. Not sure whether it is valid inside the RUN block.

RMAN> run{
2> allocate channel 'dev_0' type 'sbt_tape' parms 'SBT_LIBRARY=/opt/omni/lib/libob2oracle8_64bit.so';
3> send device type 'sbt_tape' 'OB2BARHOSTNAME=erpprod-scan.ttd.com';
send channel 'dev_0' 'OB2BARTYPE=Oracle8';
send channel 'dev_0' 'OB2APPNAME=prodcdb2';
send channel 'dev_0' 'OB2BARLIST=ERP_PROD_19C';
list backup of archivelog sequence 29222;
}4> 5> 6> 7>
