정리차원에서 적어둔다.
1. Linux에서 HDD disk 종류, CDROM 확인
1) SCSI의 경우
cat /proc/scsi/scsi
| |
# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: FUJITSU Model: MAP3367NC Rev: 5608
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: FUJITSU Model: MAP3367NC Rev: 5608
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: PE/PV Model: 1x5 SCSI BP Rev: 1.1
Type: Processor ANSI SCSI revision: 02
| |
2) IDE의 경우
cat /proc/ide/ide0/hda/model
| |
# cat /proc/ide/ide0/hda/model
ST380011A
| |
3) CDROM 확인
cat /proc/sys/dev/cdrom/info 확인 후 'drive name' 에 따라 모델정보 확인
cat /proc/ide/ide0/hda/model
| |
# cat /proc/sys/dev/cdrom/info
CD-ROM information, Id: cdrom.c 3.12 2000/10/18
drive name: hda <-- 드라이브명 확인
drive speed: 24
drive # of slots: 1
Can close tray: 1
Can open tray: 1
Can lock tray: 1
Can change speed: 1
Can select disk: 0
Can read multisession: 1
Can read MCN: 1
Reports media changed: 1
Can play audio: 1
Can write CD-R: 0
Can write CD-RW: 0
Can read DVD: 0
Can write DVD-R: 0
Can write DVD-RAM: 0

# cat /proc/ide/ide0/hda/model
TEAC CD-ROM CD-224E

# cat /proc/sys/dev/cdrom/info
CD-ROM information, Id: cdrom.c 3.12 2000/10/18
drive name: hdc <-- 드라이브명 확인
drive speed: 52
drive # of slots: 1
Can close tray: 1
Can open tray: 1
Can lock tray: 1
Can change speed: 1
Can select disk: 0
Can read multisession: 1
Can read MCN: 1
Reports media changed: 1
Can play audio: 1
Can write CD-R: 0
Can write CD-RW: 0
Can read DVD: 0
Can write DVD-R: 0
Can write DVD-RAM: 0

# cat /proc/ide/ide1/hdc/model

2. FreeBSD에서 HDD disk 종류, CDROM 확인
부팅될 때 메시지가 /var/run/dmesg.boot 파일에 저장되어 있으니 살펴보면 확인할 수 있다.
FreeBSD에 Disk Device 코드가 아래와 같으니 비교하면 쉽에 어떤 장치인지 알 수 있다.
------ -----------------------------
CODE 의미
------ -----------------------------
ad ATAPI (IDE) disk
da SCSI direct access disk
acd ATAPI (IDE) CDROM
cd SCSI CDROM
fd Floppy disk
[ RAID 인 경우 ]
amrd AMI MegaRAID®
idad Compaq Smart RAID
twed 3ware® RAID
------ -----------------------------

다음은 RAID 1과 5로 구성된 경우이다.

amr0: mem 0xdfdc0000-0xdfdfffff,0xd80f0000-0xd80fffff irq 10 at device 14.0 on pci2
amr0: Firmware 521S, BIOS H430, 256MB RAM
... 생략 ...
acd0: CDROM at ata0-master PIO4
amrd0: on amr0
amrd0: 69880MB (143114240 sectors) RAID 1 (optimal)
amrd1: on amr0
amrd1: 209640MB (429342720 sectors) RAID 5 (optimal)

pass0: Fixed Processor SCSI-2 device
