	제  목 : Linux,FreeBSD에서 HDD, CDROM정보는 어디서? 작성자 : 좋은진호(truefeel, http://coffeenix.net/ ) 작성일 : 2006.1.23(월) 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 HL-DT-ST CD-ROM GCR-8522B   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 ------  ----------------------------- ※ FreeBSD Handbook 참고    http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/disk-organization.html   acd0: CDROM at ata1-master BIOSPIO ... 생략 ... da0 at mpt0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-3 device da0: 320.000MB/s transfers (160.000MHz, offset 127, 16bit), Tagged Queueing Enabled da0: 34732MB (71132959 512 byte sectors: 255H 63S/T 4427C) da1 at mpt0 bus 0 target 1 lun 0 da1: Fixed Direct Access SCSI-3 device da1: 320.000MB/s transfers (160.000MHz, offset 127, 16bit), Tagged Queueing Enabled da1: 34732MB (71132959 512 byte sectors: 255H 63S/T 4427C)   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 at amr0 bus 0 target 6 lun 0 pass0: Fixed Processor SCSI-2 device     acd0: CDROM at ata0-master PIO4 Waiting 15 seconds for SCSI devices to settle da0 at ciss0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-0 device da0: 135.168MB/s transfers da0: 34727MB (71122560 512 byte sectors: 255H 32S/T 8716C) da1 at ciss0 bus 0 target 1 lun 0 da1: Fixed Direct Access SCSI-0 device da1: 135.168MB/s transfers da1: 69455MB (142245120 512 byte sectors: 255H 32S/T 17432C)
