Redhat 4, 5, 6 set up bare devices

RedHat 4 RAW Configuration


1 Modify the configuration file for the bare device service:/etc/sysconfig/rawdevices. Add the following 2 lines.


Format: Bare device name block device name
/dev/raw/raw1/dev/sdb1
/dev/raw/raw2/dev/sdb2


2 Set the access rights of the Oracle user to the bare device.
Edit Udev's permissions file:/etc/udev/permissions.d/50-udev.permissions
Locate the raw Device section and modify it to the following format:
# Raw Devices
raw*:oracle:dba:0660
raw/*:oracle:dba:0660




3 Confirm that the bare device service is starting and 2 nodes are executing
[Root@raw1/]# chkconfig--list rawdevices
Rawdevices 0:off 1:off 2:off 3:on 4:on 5:on 6:off


4. Start the raw devices service to confirm that the bare device was created successfully and that the permissions are correct:
[ROOT@RAW1/]# Service rawdevices restart
Assigning devices:
/DEV/RAW/RAW1-/DEV/SDB1
/dev/raw/raw1:bound to Major 8, minor 17
/DEV/RAW/RAW1-/DEV/SDB2
/dev/raw/raw1:bound to Major 8, minor 18

RedHat 5 UDEV SCSI rules configuration
1 Get the disk UUID that needs to be bound to ASM disk
#/sbin/scsi_id-g-u-s/block/sdb
Sata_vbox_harddisk_vbd306dbe0-df3367e3_


2 new/etc/udev/rules.d/99-oracle-asmdevices.rules, add the following content

RedHat 6 UDEV SCSI Rules
1 Edit the/etc/scsi_id.config file, if the file does not exist, create the file, and add the following line:
Options=--whitelisted--replace-whitespace


Note: In my test, this step can be omitted


2 Get the disk UUID that needs to be bound to ASM disk, for example, if we want to use/DEV/SDC as ASM disks, then:
# scsi_id--whitelisted--replace-whitespace--DEVICE=/DEV/SDC
1ata_vbox_harddisk_vb36a9e548-1838194a
Or
#/sbin/scsi_id-g-u-d/dev/sdb
Sata_vbox_harddisk_vbd306dbe0-df3367e3_
