最近，搞了虚拟带库玩tsm, 昨天把虚拟机停了以后，今天发现虚拟带库不能用了，分享一下解决的经验：

今天启动 tsm server 端后：
ANR8840E Unable to open device /dev/tsmscsi/lb0 with file handle 2

原因找到：
是server 的虚拟带库没有启动：
解决方法：
cd /usr/cofi/vistor
./vistor start
在把库启动起来：还是这个目录：
./vs-library --setstate online --libid 1
就会发现：

cd /proc/scsi
[root@sheng scsi]# more scsi

  Vendor: HP    Model: Ultrium 2-SCSI Rev: 1.00
  Type: Sequential-Access             ANSI SCSI revision: 03

如果没有启动起来的话，只有：
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: VMware,  Model: VMware Virtual S Rev: 1.0
  Type: Direct-Access                   ANSI SCSI revision: 02

注意，现在还不是最后的解决方案，
现在：ls -l /dev/tsmscsi/..  发现dev 下面没有tsm
而且：tsm :> show slots vtl01 也报没有该库 vtl01的信息
原因找到，是tsm 没有和vistor 虚拟带库关联

解决方法：
cd /opt/tivoli/tsm/devices/bin
./autoconf
现在发现：
[root@sheng bin]# ./autoconf

所以问题解决，很高兴。
这个时候，
TSM :> show slots vtl01 发现还没有库：vtl01 的信息，是为是么呢？
重新启动tsm server
问题解决：
