TAPE Drive
1. 백업 Device Name
일반적으로 백업 장치는 주로 /dev 밑에 존재하며, 아래와 같은 Rule을 따른다.
Basic Device Names for Backup Devices Device Type Name
--------------------------------------------------- ----------------------------
Tape /dev/rmt/n
Diskette /vol/dev/rdiskette0/unlabeled
1) TAPE 이름 설명
/dev/rmt/XAbn
- X : Drive number(0~n)
- A : Optional density
(l : low, m : medium, h : high, u : ultra, c : compressed)
- b : Berkeley compatability
- n : Optional no-rewind (n: no-rewind omit for rewind)
2. TAPE drive 상태 체크하기
mt -f /dev/rmt/$drive status
1) 아예 해당 drive가 존재하지 않을 경우,
/dev/rmt/0: No such device or address
2) 해당 drive는 존재하나 TAPE이 들어 있지 않을 경우,
/dev/rmt/1: no tape loaded or drive offline
3) TAPE 이 존재할 경우,
HP DDS-3 4MM DAT tape drive:
sense key(0x6)= Unit Attention residual= 0 retries= 0
file no= 0 block no= 0
Removable Media Device
1. Removable Media Device 접근 위치
- First diskette drive /floppy/floppy0 /vol/dev/aliases/floppy0
- Second diskette drive /floppy/floppy1 /vol/dev/aliases/floppy1
- First CD-ROM drive /cdrom/cdrom0 /vol/dev/aliases/cdrom0
- Second CD-ROM drive /cdrom/cdrom1 /vol/dev/aliases/cdrom1
- First removable hard disk /rmdisk/jaz0 /vol/dev/aliases/jaz0
or /rmdisk/zip0 /vol/dev/aliases/zip0
- First PCMCIA drive /pcmem/pcmem0 /vol/dev/aliases/pcmem0
2. Removable Media Device 접근 방법
$ volcheck
$ ls /rmdisk
jaz0/ jaz1/
3. Removable Media Device 사용중 체크
1) media 사용 중 체크
# fuser -u /media
2) Kill the process accessing the media.
# fuser -u -k /media
예) 사용중 체크
# fuser -u /cdrom/sol_10_305_sparc/s0/Solaris_10/Tools
/cdrom/sol_10_305_sparc/s0/Solaris_10/Tools: 13737c(pmorph) 4712c(pmorph)
4. Media 추가 방법
1) Become superuser.
2) Create the /reconfigure file.
# touch /reconfigure
3) Bring the system to run level 0.
# init 0
4) Turn off power to the system.
5) Connect the new media drive.
6) See your hardware handbook for specific instructions.
7) Turn on power to the system.
8) The system automatically comes up to multiuser mode.
5. Tape driver 연결 상태 확인.
