ORA-15099
官方文档解释为
请注意 ASM对于单盘的限制为2T。也就是说单个LUN不能大于2TB。个人建议不要大于1.7T。
ORA-15099: disk 'string' is larger than maximum size of string MBs
Cause: The specified size of the disk was too big to allow the disk to become part of the diskgroup.
Action: Specify a smaller disk size than the maximum allowed size.
这次在联通机房遇到了这个BUG。1.2T的lun不被ASMCA识别。
清空了磁盘头还是没用，到metalink一查，果然有个BUG。
在AIX上，单个LUN大于1T，ASM看到的可能要比1T大。由于时间较紧，所以只好在容量上进行妥协。
把1.2T的lun降为900G，果然可以识别了。
