mc (Media Changer) 사용법 부탁합니다.

백업 엔지니어입니다.
가끔 Library 자체 Drive Test를 하는데...쉽지가 않습니다. MC Command 사용법 알려주셨으면 합니다.
선배님들의 많은 조언 부탁드립니다.
고맙습니다.

mc (Media Changer) 사용법 부탁합니다.

Hi,

I have found the following useful info from itrc.hp.com.

*********************************************

You need to tell it the address of the changer:
mc -r DS -p /dev/rac/c44t0d1
or for multiple commands set the environment variable LIBRARY before calling mc:

export LIBRARY=/dev/rac/c44t0d1

To move media from an embedded drive to slot 5 and then move media from slot 2 to an embedded drive.
mc -s D1 -d S5 -s S2 -d D1

To check if a move from a Data Transfer element to a Storage element is possible.
mc -c DS

Cheers,
