rac1节点不能启动ＣＲＳ
今天重启RAC主机后发现RAC1节点的CRS服务不能开启，RAC2正常 [grid@rac1 ~]$ crsctl check crs CRS-4638: Oracle High Availability Services is online CRS-4535: Cannot communicate with Cluster Ready Services CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online [grid@rac1 ~]$ crs_stat -t CRS-0184: Cannot communicate with the CRS daemon. 检查OCR时发现AMS的共享磁盘有问题 [grid@rac1 ~]$ ocrcheck PROT-602: Failed to retrieve data from the cluster registry PROC-26: Error while accessing the physical storage ASM error [SLOS: cat=8, pn=kgfolclcpi1, dep=204, loc=kgfokge AMDU-00204: Disk N0001 is in currently mounted diskgroup DATA AMDU-00201: Disk N0001: 'ORCL:ASM_DISK1'

找了很多资料后怀疑是由于ASM实例没启 [oracle@rac1 ~]$ asmcmd Connected to an idle instance. ASMCMD> help asmcmd [-vV] [-a ] [-p] [command]
The environment variables ORACLE_HOME and ORACLE_SID determine the instance to which the program connects, and ASMCMD establishes a bequeath connection to it, in the same manner as a SQLPLUS / AS SYSASM. The user must be a member of the OSASM group.
Specifying the -V option prints the asmcmd version number and exits immediately.
Specifying the -v option prints extra information that can help advanced users diagnose problems.
Specify the -a option to choose the type of connection. There are only two possibilities: connecting as SYSASM or as SYSDBA. The default value if this option is unspecified is SYSASM.
Specifying the -p option allows the current directory to be displayed in the command prompt, like so:
ASMCMD [+DATA/ORCL/CONTROLFILE] >
[command] specifies one of the following commands, along with its parameters.
Type "help [command]" to get help on a specific ASMCMD command.
commands: --------
md_backup, md_restore
lsattr, setattr
cd, cp, du, find, help, ls, lsct, lsdg, lsof, mkalias mkdir, pwd, rm, rmalias
chdg, chkdg, dropdg, iostat, lsdsk, lsod, mkdg, mount offline, online, rebal, remap, umount
dsget, dsset, lsop, shutdown, spbackup, spcopy, spget spmove, spset, startup
chtmpl, lstmpl, mktmpl, rmtmpl
