ASM之建立ASM例項時的常見故障

ASM之建立ASM例項時的常見故障

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
1.建立磁碟時出現錯誤可以檢視asm日誌
tail -f /var/log/oracleasm

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
2.啟動asm例項時出現ORA-29701錯誤
ORA-29701: unable to connect to Cluster Manager

首次需要啟用css服務，使用root帳戶,執行$ORACLE_HOME/bin/localconfig add
如果下次啟動例項的時候仍然碰到如下報錯：
ORA-29701: unable to connect to Cluster Manager
那麼檢查/etc/inittab 檔案，看看是否有下面這行 h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1 如果沒有請新增，如果被註釋了請取消註釋(root帳戶)。 也可以使用root帳戶執行/u01/oracle/10g/bin/localconfig reset來解決

3.磁碟搜尋路徑問題
SQL> create diskgroup DG1 normal redundancy disk 'ORCL:VOL1','ORCL:VOL2';

create diskgroup DG1 normal redundancy disk 'ORCL:VOL1','ORCL:VOL2' * ERROR at line 1:
ORA-15018: diskgroup cannot be created ORA-15031: disk specification 'ORCL:VOL2' matches no disks
ORA-15031: disk specification 'ORCL:VOL1' matches no disks

使用oraclasm建立磁碟後，預設會在/dev/oracleasm/disks目錄下新增剛剛建立的磁碟對映
修改asm_diskstring修改路徑之後再次建立即可
alter system set asm_diskstring='/dev/oracleasm/disks/VOL*'
