磁盘组不能自动挂载

磁盘组不能自动挂载的
原因有2:
1 、asm_diskgroups 不能为空,需要配置所有的磁盘组
2、磁盘组的属性AUTO_START应该设置为always,该问题是bug 8663101 : 修改用 crsctl modify resource ora.DATA.dg -attr AUTO_START=always,查询用:crsctl stat res ora.OCR.dg -p

多次测试 所有磁盘均能正常挂载
该解决办法出自 ID:1065158.1 问题原因可能涉及到11.2.0.1的一个BUG bug 8663101 该BUG 在12.2.0.2已经被修复
下一步 该升级数据库了
1. Manually start the diskgroup: srvctl start diskgroup -g <dg_name> [-n "<node_list>"]
or
2. Modify the attribute AUTO_START to "always"
crsctl modify resource ora.<diskgroup>.dg -attr AUTO_START=always
Diskgroup resource shows status offline after restart even it is mounted in ASM instance (文档 ID 1065158.1) | 转到底部 |
In this Document Symptoms Changes Cause Solution References APPLIES TO:Oracle Database - Enterprise Edition - Version 11.2.0.1.0 and later
SYMPTOMSAfter restart the 11.2 HAS stack, the diskgroup (.dg) resource is showing "OFFLINE" status, but diskgroup is mounted in the ASM instance. $ crsctl stat res ora.DATA.dg
SQL> conn / as sysdba CHANGESFrom the crsd.log: 2010-02-05 16:05:09.988: [ A**][56] ora.DATA.dg host1 1 received state from probe request. Old state = UNKNOWN, New state = OFFLINE
2010-02-05 16:05:09.799: [ A**][9] ora.DATA.dg host1 1 state changed from: UNKNOWN to: OFFLINE CAUSEThis is caused by an unpublished bug 8663101 11.2 DG RES OFFLINE, BUT DISKGROUP MOUNTED AFTER RESTART HAS STACK SOLUTIONThe bug has been fixed in 11.2.0.2 patchset. 1. Manually start the diskgroup: REFERENCES
