Environment: RHEL-5.8 Oracle _ 10gR2

Bind a bare Device

1. [Root @ localhost ~] # Fdisk-l
3. Disk/dev/sda: 32.2 GB, 32212254720 bytes
4. 255 heads, 63 sectors/track, 3916 cylinders
5. Units = cylinders of 16065*512 = 8225280 bytes
7. Device Boot Start End Blocks Id System
8. /Dev/sda1*1 13 104391 83 Linux
9. /Dev/sda2 14 1288 10241437 + 83 Linux

18. /Dev/sda12 1380 1392 104391 8e Linux LVM

② In/etc/sysconfig/rawdevices, add:

1. /Dev/raw/raw5/dev/sda5
2. /Dev/raw/raw6/dev/sda6
3. /Dev/raw/raw7/dev/sda7
4. /Dev/raw/raw8/dev/sda8
5. /Dev/raw/raw9/dev/sda9
6. /Dev/raw/raw10/dev/sda10
7. /Dev/raw/raw11/dev/sda11
8. /Dev/raw/raw12/dev/sda12

③ Under assign_raw at start of/etc/rc. d/init. d/rawdevices, add:

1. Sleep 3
2. Chown-R oracle: oinstall/dev/raw/

④ Check bare Devices

1. [Root @ localhost init. d] # chkconfig rawdevices on
2. [Root @ localhost init. d] # partprobe
3. [Root @ localhost init. d] # service rawdevices restart
4. Assigning devices:
