Oracle 11gR2启动ASM实例时遭遇ORA-29701
grid@linux:~> sqlplus "/as sysasm"

SQL> startup
ORA-01078: failure in processing system parameters
ORA-29701: unable to connect to Cluster Synchronization Service
grid@linux:~> crsctl check css
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
grid@linux:~> ps -ef |grep cssd
grid 5975 5932 0 14:51 pts/0 00:00:00 grep cssd
果然没有CSS的服务daemon进程,再看一下HAS(High Availability Service)的状态
grid@linux:~> crsctl check has
CRS-4638: Oracle High Availability Services is online
grid@linux:~> ps -ef |grep d.bin
grid 4561 1 2 14:35 ? 00:00:28 /oracle/app/grid_home/bin/ohasd.bin reboot
grid 5988 5932 0 14:51 pts/0 00:00:00 grep d.bin
发现HAS的服务确实启动了的,而ora.cssd和ora.diskmon这2个服务是依赖于HAS维护的
进一步查看各资源的状态
grid@linux:~> crs_stat -t

再看一下ora.cssd和ora.diskmon的属性
grid@linux:~>
grid@linux:~> crs_stat -p ora.cssd
NAME=ora.cssd
TYPE=ora.cssd.type
ACTION_SCRIPT=
ACTIVE_PLACEMENT=0
AUTO_START=never
CHECK_INTERVAL=30
DESCRIPTION="Resource type for CSSD"
FAILOVER_DELAY=0

FAILURE_THRESHOLD=5

RESTART_ATTEMPTS=5
SCRIPT_TIMEOUT=600
START_TIMEOUT=600
STOP_TIMEOUT=900
UPTIME_THRESHOLD=1m
grid@linux:~> crs_stat -p ora.diskmon
NAME=ora.diskmon
TYPE=ora.diskmon.type
ACTION_SCRIPT=
ACTIVE_PLACEMENT=0
AUTO_START=never
CHECK_INTERVAL=20
DESCRIPTION="Resource type for Diskmon"
FAILOVER_DELAY=0
FAILURE_INTERVAL=3
FAILURE_THRESHOLD=5
HOSTING_MEMBERS=
PLACEMENT=balanced
RESTART_ATTEMPTS=10
SCRIPT_TIMEOUT=60
START_TIMEOUT=60
STOP_TIMEOUT=60
UPTIME_THRESHOLD=5s
到这里基本就找到了原因了,可以看到这两个资源的AUTO_START属性默认都设置为never,也就是说他们不会随着HAS服务的启动而自动启动的,尽管默认情况下HAS服务是开机自动启动的.
手工启动：
grid@linux:~> crsctl start resource ora.cssd
CRS-2672: Attempting to start 'ora.cssd' on 'linux'
CRS-2679: Attempting to clean 'ora.diskmon' on 'linux'
CRS-2681: Clean of 'ora.diskmon' on 'linux' succeeded
CRS-2672: Attempting to start 'ora.diskmon' on 'linux'
CRS-2676: Start of 'ora.diskmon' on 'linux' succeeded
CRS-2676: Start of 'ora.cssd' on 'linux' succeede
、注:ora.cssd和ora.diskmon这两个服务是有依赖关系的，启动哪个都会把两个都起来.、

PS:
1)默认情况下HAS(High Availability Service)是自动启动的.通过如下命令可以取消和启用自动启动
crsctl disable has
crsctl enable has
2)HAS手动启动和停止
crsctl start has
crsctl stop has
3)查看HAS的状态
crsctl check has
4)如果想让ora.css和ora.diskmon服务随着HAS的启动而自动启动，那么你可以这两个服务的AUTO_START属性
crsctl modify resource "ora.cssd" -attr "AUTO_START=1"
or
crsctl modify resource "ora.diskmon" -attr "AUTO_START=1"
5)如果想取消ora.css和ora.diskmon的Auto start
crsctl modify resource "ora.cssd" -attr "AUTO_START=never"
crsctl modify resource "ora.diskmon" -attr "AUTO_START=never"
