察看磁带机多久没有被清洗:
通常磁带机每使用30 小时（8mm20GB 为72 小时）或至少每月清洁一次，
不要等故障灯亮起后再清洁。可用“/usr/lpp/diagnostics/bin/
utape –cd rmt0 –n“查看磁带机使用时数。
1、执行脚本 # /usr/lpp/diagnostics/bin/utape
在下面的选项中 选择 " rmt0 U787F.001.DPM5ANM-P1-T10-L0-L0"
SCSI TAPE SERVICE AID 802331
Select the device.
Move cursor to the selection, then press Enter.
rmt0 U787F.001.DPM5ANM-P1-T10-L0-L0
LVD SCSI 4mm Tape Drive
再选择 "Display Time Since Drive Was Last Cleaned"
SCSI TAPE SERVICE AID 802332
FOR rmt0 IN LOCATION U787F.001.DPM5ANM-P1-T10-L0-L0
Move cursor to the selection, then press Enter.
Display Time Since Drive Was Last Cleaned
Copy Trace Table

最后出现最后一次磁带清洗到现在的时间:
DISPLAY TIME SINCE THE DRIVE WAS LAST CLEANED 802336
FOR rmt0 IN LOCATION U787F.001.DPM5ANM-P1-T10-L0-L0
Usage time since the drive was last cleaned: 38.75 hours.
Device rmt0 does NOT need cleaning at this time.
To continue, press Enter.

磁带机清洗问题
我们的磁带机一般用了2个月左右，它就会有个提示我们要清洗磁带的灯会闪，这时我一般把清洗磁带的盘放进去，过5分钟左右就好了
