Oracle 11gR2 RAC安裝Clusterware結(jié)束， 在第二個(gè)節(jié)點(diǎn)執(zhí)行root.sh腳本的是報(bào)如下錯(cuò)誤：

DiskGroup DATA1 creation failed with the following message:

ORA-15018: diskgroup cannot be created

ORA-15072: command requires at least 1 regular failure groups, discovered only 0

在Oracle的官網(wǎng)搜了一下，相關(guān)解釋如下

Applies to:

Oracle Server - Enterprise Edition - Version: 11.2.0.1 and later???[Release: 11.2 and later ]

Information in this document applies to any platform.

Symptoms

While installing Oracle Grid Infrastructure with ASM, root.sh ran successfully in first node, but fails on the second node.

Error example

1. root.sh failed on second node with following errors

-------------------------------------------------------

DiskGroup DATA1 creation failed with the following message:ORA-15018: diskgroup cannot be created

ORA-15072: command requires at least 1 regular failure groups, discovered only 0

Configuration of ASM failed, see logs for details

2. rootcrs_nodename.log

-----------------------

2010-02-03 13:40:43: Configuring ASM via ASMCA

2010-02-03 13:40:43: Executing as oracle: /u01/app/1120/grid/bin/asmca -silent -diskGroupName DATA1 -diskList ORCL:DATA1 -redundancy EXTERNAL -configureLocalASM

2010-02-03 13:40:43: Running as user oracle: /u01/app/1120/grid/bin/asmca -silent -diskGroupName DATA1 -diskList ORCL:DATA1 -redundancy EXTERNAL -configureLocalASM

2010-02-03 13:40:43: Invoking "/u01/app/1120/grid/bin/asmca -silent -diskGroupName DATA1 -diskList ORCL:DATA1 -redundancy EXTERNAL -configureLocalASM" as user "oracle"

2010-02-03 13:40:51: Configuration of ASM failed, see logs for details

3. On the 2nd node

/etc/oratab files shows +ASM1, rather than +ASM2

4. The following commands on the 2nd node show the ASM disk information correctly

/etc/init.d/oracleasm listdisks

/etc/init.d/oracleasm scandisks

ls -ltr /dev/oracleasm/disks

Cause

After configuring multipath disks on Linux x86-64, proper parameters have not been configured in /etc/sysconfig/oracleasmhttps://www.cndba.cn/Dave/article/988

Solution

On all nodes,

1. Modify the /etc/sysconfig/oracleasm with:

ORACLEASM_SCANORDER="dm"

ORACLEASM_SCANEXCLUDE="sd"

2. restart the asmlib by :

# /etc/init.d/oracleasm restart

3. Run root.sh on the 2nd node

在這里要注意的事，在運(yùn)行root.sh腳本的時(shí)候，會(huì)報(bào)如下錯(cuò)誤：

Using configuration parameter file: /oracle/grid/crs/install/crsconfig_params

CRS is already configured on this node for crshome=0

Cannot configure two CRS instances on the same cluster.

Please deconfigure before proceeding with the configuration of new home.

因?yàn)橹耙呀?jīng)運(yùn)行過了。 我們需要把之前注冊(cè)的信息 刪除之后，在運(yùn)行root.sh腳本。 執(zhí)行如下命令，刪除節(jié)點(diǎn)注冊(cè)信息：

# /oracle/grid/crs/install/roothas.pl -delete -force -verbose

待刪除完成后在執(zhí)行，就不會(huì)報(bào)錯(cuò)了。
