更换磁带机后系统操作步骤
1．STK磁带库更换完磁带机后，系统要做相关的修改，才能使用该磁带机；
2．操作系统扫描硬件设备，搜索到相应的磁带机设备；
在HP-UX中，执行下面的命令扫描出磁带机；
HQxNBUA:/var/adm/syslog]ioscan -fnCtape
Class I H/W Path Driver S/W State H/W Type Description
======================================================================== tape 0 2/0/2/1/1.2.0 stape CLAIMED DEVICE HP C5683A

/dev/rmt/1mn /dev/rmt/c18t3d0BESTb /dev/rmt/c18t3d0D3480 /dev/rmt/c18t3d0D3480nb
如果没有发现更换的磁带机，首先检查磁带机使用的光纤卡，记录光纤卡的设备文件；
HQxNBUA:/var/adm/syslog]ioscan -fnkCfc
Class I H/W Path Driver S/W State H/W Type Description
===================================================================

/dev/td0
fc 1 2/0/10/1/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter
/dev/td1
用fcmsutil命令更新卡上的属性
在/var/adm/syslog/syslog.log 中获取类似nport 0x610713的报错信息，提取这个代码
Fcmsutil /dev/tdx
确认HBA卡，查看HBA卡的WWN
HQxNBUA:/var/adm/syslog]fcmsutil /dev/td0 replace_dsk 0x610713
Disk at nportid 0x610713(Loop_id 0) will not be authenticated
其中，0x610713是该光纤卡在交换机上的port id，该port id可以在syslog文件中找到；
rmsf –H H/W Path
重新扫描磁带机；
HQxNBUA:/var/adm/syslog]ioscan -fnCtape
