Dear user097815,
I think there are a couple of syntax errors and it would be better for you to first try each one one-by-one than add them into your "run" block.
RMAN> allocate channel for maintenance device type 'SBT_TAPE';
using target database control file instead of recovery catalog
allocated channel: ORA_MAINT_SBT_TAPE_1
channel ORA_MAINT_SBT_TAPE_1: sid=910 devtype=SBT_TAPE
channel ORA_MAINT_SBT_TAPE_1: Data Protector A.06.10/611
RMAN> allocate auxiliary channel t1 type 'sbt_tape';

}Hope That Helps.
