after OS reboot ,11g RAC asm not automatic startup ORA-27102
昨安装成功了11G 203 RAC的GIRD,当时查看正常，今天重启了一下操作系统linux，发现grid没启动，crs_stst -t 查看集群件资源无法查看，crsctl check crs 检查Cluster Ready Services没启，
查看日志

怀疑是kernel 参数问题检查
/etc/sysctl.conf发现一可疑处
# Oracle-Validated setting for kernel.shmmax is 4398046511104 on x86_64 and 4294967295 on i386 architecture. Refer Note id 567506.1
kernel.shmmax = 4398046511104因为我是没装validated，从其实机器copy的配置文件，并且我的本机是oel5.8 32bit,所以这个参数太大。
修改为kernel.shmmax=4294967295os reboot。
