目的：将/dev/sdb6作为归档盘添加到DSC集群中
1.挂存储
在两个节点的/etc/udev/rules.d/70-persistent-ipoib.rules添加以下内容

ACTION=="add", KERNEL=="sdb6", RUN+="/bin/raw /dev/raw/raw6 %N"

添加完后为

ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdb3", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sdb4", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="sdb5", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="sdb6", RUN+="/bin/raw /dev/raw/raw6 %N"
ACTION=="add",KERNEL=="raw[1-6]",OWNER="dmdba",GROUP="dinstall", MODE="660"

两个节点重新加载磁盘信息

[root@ ~]# /sbin/udevadm trigger --type=devices --action=change
[root@ ~]# /sbin/udevadm control --reload-rules

2.初始化ARCH盘

[dmdba@ bin]# ./dmasmcmd
DMASMCMD V8
ASM>create asmdisk '/dev/raw/raw6' 'ARCH0'
[TRACE]The ASM initialize asmdisk /dev/raw/raw6 to name DMASMARCH0

3.创建 ARCH磁盘组

[dmdba@ bin]# ./dmasmtool DCR_INI=/home/config/dmdcr.ini
DMASMTOOL V8
ASM>create diskgroup 'DMARCH' asmdisk '/dev/raw/raw6'

4.修改dmarch.ini文件
将归档路径修改为+DMARCH磁盘组下

节点一
[ARCHIVE_LOCAL1]
  ARCH_TYPE            = LOCAL
  ARCH_DEST            = +DMARCH/arch_0
  ARCH_FILE_SIZE       = 2048
  ARCH_SPACE_LIMIT     = 51200
[ARCH_REMOTE1]
  ARCH_TYPE            = REMOTE
  ARCH_DEST            = DSC1
  ARCH_INCOMING_PATH   = +DMARCH/arch_1
  ARCH_FILE_SIZE       = 2048
  ARCH_SPACE_LIMIT     = 51200

节点二
[ARCHIVE_LOCAL1]
  ARCH_TYPE            = LOCAL
  ARCH_DEST            = +DMARCH/arch_1
  ARCH_FILE_SIZE       = 2048
  ARCH_SPACE_LIMIT     = 51200
[ARCH_REMOTE1]
  ARCH_TYPE            = REMOTE
  ARCH_DEST            = DSC0
  ARCH_INCOMING_PATH   = +DMARCH/arch_0
  ARCH_FILE_SIZE       = 2048
  ARCH_SPACE_LIMIT     = 51200

5.重启数据库服务后验证归档状态

SQL> select * from v$arch_STATUS;
行号     ARCH_TYPE ARCH_DEST      ARCH_STATUS ARCH_SRC
---------- --------- -------------- ----------- --------
1          LOCAL     +DMARCH/arch_0 VALID       DSC0
2          REMOTE    +DMARCH/arch_1 VALID       DSC1
