RedHat 4 RAW配置


1修改裸裝置服務的配置檔案: /etc/sysconfig/rawdevices. 新增下面2行。


 格式：裸裝置名 塊裝置名
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2


2 設定Oracle 使用者對裸裝置的訪問許可權。
編輯UDEV的許可權檔案：/etc/udev/permissions.d/50-udev.permissions
找到raw device部分，修改成如下格式：
# raw devices
raw*:oracle:dba:0660
raw/*:oracle:dba:0660




3 確認裸裝置服務自啟動，2個節點都要執行
[[email protected] /]# chkconfig --list rawdevices
rawdevices      0:off   1:off   2:off   3:on    4:on    5:on    6:off


4. 啟動raw devices 服務，確認裸裝置建立成功，許可權正確：
[

[email protected] /]# 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


done


[[email protected] ~]$ cd /dev/raw
[[email protected] raw]$ ls -lrt
total 0
crw-rw----  1 oracle dba 162, 1 Feb 28 03:08 raw1
crw-rw----  1 oracle dba 162, 2 Feb 28 03:08 raw2

2 重啟服務：


[

[email protected] ~]# start_udev
Starting udev:         [  OK  ]


3 檢視raw裝置：
[[email protected] ~]# ls -lrt /dev/raw


 


RedHat 5 UDEV SCSI Rules配置
1 獲取需要繫結為ASM Disk的磁碟uuid
# /sbin/scsi_id -g -u -s /block/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_


2 新建/etc/udev/rules.d/99-oracle-asmdevices.rules,增加以下內容
KERNEL=="sd*1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asm-disk1", OWNER="oracle", GROUP="dba", MODE="0660"


3 重啟服務：
[

[email protected] ~]# start_udev
Starting udev:         [  OK  ]


 


RedHat 6 UDEV SCSI Rules
1 編輯/etc/scsi_id.config檔案，如果該檔案不存在，則建立該檔案，新增如下行：
options=--whitelisted --replace-whitespace


備註：在我的測試中，此步驟可以省略


2 獲取需要繫結為ASM Disk的磁碟uuid，比如我們要使用/dev/sdc作為ASM磁碟，那麼：
# scsi_id --whitelisted --replace-whitespace --device=/dev/sdc
1ATA_VBOX_HARDDISK_VB36a9e548-1838194a
或
# /sbin/scsi_id -g -u -d /dev/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_


3 新建/etc/udev/rules.d/99-oracle-asmdevices.rules,增加以下內容
