### RHEL5 scsi id 확인 예제

[root@rhel5 rules.d]# /sbin/scsi_id -g -u -s /block/sdc 3600a0b800013275100000015427b625e

[root@rehel5 rules.d]# /sbin/scsi_id -g -u -s /class/scsi_tape/nst0
SHP_C7438A_HU110180G4

### RHEL6 scsi id 확인 예제

# /sbin/scsi_id –whitelisted –replace-whitespace –device=/dev/sda
1ATA_ST31000524AS_6VPDF8ML

# /sbin/scsi_id -g -u -d /dev/sda
1ATA_ST31000524AS_6VPDF8ML

### RHEL 5 확인된 scsi id 로 udev rules 적용 예제

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="{UniqueIdentifier}", SYMLINK+="devicename%n"

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="3600a0b800013275100000015427b625e", SYMLINK+="mydevice%n"

KERNEL=="nst[0-9]*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -u -g", RESULT=="{UniqueIdentifier}", NAME="rmt0"

### RHEL 6 확인된 scsi id 로 udev rules 적용 예제

### UDEV RULES 구성관련 확인

# RHEL6

udevadm test /block/sda 2>&1|grep pwlvm_disk

# RHEL5

udevtest /block/sda | grep pwlvm_disk

### UDEV RULES 적용

#start_udev
