tsm卡带，怎么解决?

q mount

volume TB0000 is mounted r/w in drive drive7 (/dev/IBMtape6),status:dismounting.

upd path ....

drive drive7 is currently in use

q path

drive7 online=no

后台进程

unable to open drive /dev/ibmtape6

failure connecting to library client node*  to manage volume TB0000

带库是ibm3584的，6.3的tsm，以前出现问题时，手动取出磁带，回滚tsm数据库到某个时间点，再解决的，可是很麻烦，请问大家有遇到这个问题吗?多谢了!
