LTO tape drive 一問
雖然LTO(or DLT)tape medium在防刮的設計上比其它類似tape drive(dds for example)要好很多.
但只要是medium與head有接觸機會的device都需要clean(避免刮傷tape).
比較上,DDS tape要主動固定clean(once per week if dds backup every day;pnce per month if dds backup less 5 times a month),否則等"clean led"亮了再clean,head 多多少少已受刮傷,減少壽命;反之LTO head 最好等到"clean led"亮了,才被動clean,否則clean太勤反而會過度損傷head(這是為什麼一般Library clean trigger設在 "dirty detected").
所以你聽到的說法應該是"不需要主動的 clean". fyi.

LTO tape drive 一問
No clean tape 所引起的問題大都是"Dirty drive detection".
EMS event 100084 大都發生在target devcie(0/10/0/0.8.0.255.7.10.3 in your case)can not found or can not access.
1.如果此device 屬於library (含FC/SCSI bridge/router)之一,則run device-mapping check map是否跑掉(map configuration issue or NSR f/w issue).
Wrokaround solution is reboot library.
2.如果此device 屬於standalone,fault led should be lit,f/w or hw replace would be the solution.
Hope this is useful for your question.
