这是脚本
RMAN> RUN {
2> ALLOCATE CHANNEL CH00 TYPE 'SBT_TAPE';
3> SEND 'NB_ORA_SERV=backupserver,NB_ORA_CLIENT=p550a_svc';
4> RESTORE CONTROLFILE FROM '/cntrl_36931_1_936134229';
5> RELEASE CHANNEL CH00;

问题解决
通过分析与文档的解释，确定了问题所在，即netbackup中设置的client name与client端的hostname不相同，导致了恢复的时候，无法找到正确的途径，导致恢复失败。
将netbackup服务器上的client name修改成netbackup客户端的hostname，重新运行sbttest sbt_tape，restore测试通过。
看看能否解决你的问题

试试这个
问题和你一样
问题描述：
RMAN> run {
2> allocate channel t1 type \'sbt_tape\';
3> send \'NB_ORA_SERV=netbackup,NB_ORA_CLIENT=hz1\';
4> restore controlfile to \'/oracle11/oradata/control01.ctl\' from \'/c-3201563006-20141026-02\';
5> release channel t1 ;
6> }
allocated channel: t1
channel t1: SID=239 device type=SBT_TAPE
channel t1: Veritas NetBackup for Oracle - Release 7.0 (2010010501)
sent command to channel: t1
Starting restore at 29-OCT-14

解决方法：
异机环境的 oracle 软件属组，用户是否与源环境一致？
这里的一致包括user id ，group id 也是要一样的
NBU 自带的备份集权限参数：
bkup_image_perm =[user | group | any]
uset=>600
group =》640
any=》660
