在Solaris平台中ASM所需磁盘的Format过程-服务器评测

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: 42
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：

以上过程完成后，下一步工作就是在ASM环境下添加磁盘，操作步骤如下：
