在Solaris平台中ASM所需磁盘的Format过程

近期在增加ASM磁盘过程中遇到如下错误：SQL> alter diskgroup datadg add disk "/dev/rac/DBdg01" rebalance power 0;
alter diskgroup datadg add disk "/dev/rac/DBdg01" rebalance power 0
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15031: disk specification "/dev/rac/DBdg01" matches no disks
ORA-15025: could not open disk "/dev/rac/DBdg01"
ORA-15056: additional error message
SVR4 Error: 13: Permission denied

Additional information: –1897261352 经过两天排查，最终的处理方法归结为在OS环境通过Format命令格式化分区时如下的0号分区没有留空间，6号区从0号Cylinders 开始导致的。Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 4 117.66MB （5/0/0） 240975
具体处理过程如下： bash-3.00# format
