10G RAC ASM无法启动



一数据库服务器意外断电, 重启发现无法启动ASM:

[Rac10g01][/home/oracle]$ srvctl start asm -n rac10g01
PRKS-1009 : 无法启动节点 "rac10g01", [PRKS-1009 : 无法启动节点 "rac10g01", [CRS-1028: Dependency analysis failed because of:
CRS-0223: Resource 'ora.rac10g01.ASM1.asm' has placement error.] 上的 ASM 实例 "+ASM1"] 上的 ASM 实例 "+ASM1"
  [PRKS-1009 : 无法启动节点 "rac10g01", [CRS-1028: Dependency analysis failed because of:
CRS-0223: Resource 'ora.rac10g01.ASM1.asm' has placement error.] 上的 ASM 实例 "+ASM1"]

试着采用如下方法解决:
[Rac10g01][/home/oracle]$ export ORACLE_SID=+ASM1
[Rac10g01][/home/oracle]$ sqlplus / as sysdba

启动数据库成功.

还可以采用crs相关命令解决:

1. ./crs_stat -t
ora….SM1.asm application ONLINE UNKNOWN
状态为UNKNOWN

./crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
正常

2. 执行:
./crs_stop -all
./crs_start -all
./crs_stat -t
ora….SM1.asm application ONLINE OFFLINE

3. 启动ASM
srvctl start asm -n rac10g01 -i +ASM1
