（已解决）虚拟带库 rman 备份问题，请帮解疑

zyl19861126

模拟lan-free环境，mater server为redhat 5.4，带库为mhvtl，使用iscsi共享带库出去，media server为虚拟机redhat 5.4，使用iscsi能成功看见带库。

在master server、media server上能成功备份文件系统，但备份 media server 上面的Oracle数据库时就出错。手工备份会卡住，但在控制台上面就看见失败，无报错。

RMAN> run {
2> allocate channel ch00 type sbt_tape;
3> backup current controlfile;
4> release channel ch00;
5> }

allocated channel: ch00
channel ch00: SID=70 device type=SBT_TAPE
channel ch00: Veritas NetBackup for Oracle - Release 7.5 (2012020801)

Starting backup at 27-MAR-2012 12:24:43
channel ch00: starting full datafile backup set
channel ch00: specifying datafile(s) in backup set
including current control file in backup set
channel ch00: starting piece 1 at 27-MAR-2012 12:24:47

如上，卡住不动了。

而创建策略备份的话，也是卡住，一直在connecting状态。请问是怎么回事？

我又在master机器上面创建了一个disk存储，并且也能够备份文件系统。新建了一个policy，使用的就是这个文件系统。但rman备份数据库还是卡住不动，而在jnpSA上面已经显示红色“X"图标了。

RMAN> run {
2>      allocate channel c1 type sbt parms="ENV=(NB_ORA_SERV=hb3,NB_ORA_POLICY=VCSDB_FULL_BKP3)";
3>      backup archivelog all delete input;
4>      release channel c1;
5> }

allocated channel: c1
channel c1: SID=10 device type=SBT_TAPE
channel c1: Veritas NetBackup for Oracle - Release 7.5 (2012020801)

原来是NB_ORA_CLIENT=加错了。
