12c rac安装grid报错，在节点2无法启动asm

lai

操作系统：suse 11 sp1 64bit
数据库：oracle 12.1
主机名：fly007-dm-client-rac01,fly007-dm-client-rac02

如上主机名不管是大写，还是小写，在安装grid到节点2的时候，都报错如下：
CRS-2672: Attempting to start 'ora.asm' on 'fly007-dm-client-rac02'
CRS-5017: The resource action "ora.asm start" encountered the following error:
ORA-03113: end-of-file on communication channel

Died at /opt/oracrs/product/12c/grid/crs/install/crsinstall.pm line 941.
The command '/opt/oracrs/product/12c/grid/perl/bin/perl -I/opt/oracrs/product/12c/grid/perl/lib -I/opt/oracrs/product/12c/grid/crs/install /opt/oracrs/product/12c/grid/crs/install/rootcrs.pl ' execution failed

但是将主机名更改为rac01,rac02，rac安装成功
rac安装对主机名的大小写有关系？对哪些特殊字符有限制，如中横线，下划线？对主机名的字符长度是否有限制？
麻烦大神帮忙定位问题，万分感谢~

在节点2执行/opt/oracrs/product/12c/grid/root.sh的时候报错的
