【RAC】 oracleasm 工具對應的日誌記錄
因為刪除Clusterware之後，ocr還在磁碟中，使用dd命令格式化磁碟，但是oracle提供了oracleasm工具，所以看看oracleasm deletedisk的操作具體做了什麼
------------------------------------------------------------------
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL101
Removing ASM disk "VOL101": [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL102
Removing ASM disk "VOL102": [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL103
Removing ASM disk "VOL103": [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL104
Removing ASM disk "VOL104": [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL201
Removing ASM disk "VOL201": [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL202
Removing ASM disk "VOL202": [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL203
Removing ASM disk "VOL203": [ OK ]
[root@rac1 ~]# /etc/init.d/oracleasm deletedisk VOL204
Removing ASM disk "VOL204": [ OK ]
對應日誌：deletedisk操作刪除了磁碟的頭部資訊。

關於重啟oracleasm 的日誌記錄:
[root@rac1 dev]# service oracleasm stop
Dropping Oracle ASMLib disks: [ OK ]
Shutting down the Oracle ASMLib driver: [ OK ]
對應日誌：
Unmounting ASMlib driver filesystem: /dev/oracleasm
Unloading module "oracleasm": oracleasm
-------------------------------------------------------------------
[root@rac1 dev]# service oracleasm start

下面是建立asm磁碟的日誌記錄：
[root@rac1 dev]# /etc/init.d/oracleasm createdisk VOL101 /dev/sdc1
Marking disk "VOL101" as an ASM disk: [ OK ]
[root@rac1 dev]#/etc/init.d/oracleasm createdisk VOL102 /dev/sdc2
Marking disk "VOL102" as an ASM disk: [ OK ]
[root@rac1 dev]# /etc/init.d/oracleasm createdisk VOL103 /dev/sdd1
Marking disk "VOL103" as an ASM disk: [ OK ]
[root@rac1 dev]# /etc/init.d/oracleasm createdisk VOL104 /dev/sdd2
Marking disk "VOL104" as an ASM disk: [ OK ]
[root@rac1 dev]# /etc/init.d/oracleasm createdisk VOL201 /dev/sde1
Marking disk "VOL201" as an ASM disk: [ OK ]
[root@rac1 dev]# /etc/init.d/oracleasm createdisk VOL202 /dev/sde2
Marking disk "VOL202" as an ASM disk: [ OK ]
[root@rac1 dev]# /etc/init.d/oracleasm createdisk VOL203 /dev/sdf1
Marking disk "VOL203" as an ASM disk: [ OK ]
[root@rac1 dev]# /etc/init.d/oracleasm createdisk VOL204 /dev/sdf2
Marking disk "VOL204" as an ASM disk: [ OK ]
下面是建立asm磁碟的日誌記錄：先檢查磁碟組是否已經被建立或者初始化！
