今天在给ASM扩磁盘组的时候发现11.2.0.2上asmcmd中lsdg命令所显示的磁盘组数不正确，现象如下:
Node A lsdg正常:
ASMCMD> lsdg
State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files Name
MOUNTED EXTERN N 512 4096 1048576 142976 50596 0 50596 0 Y DATA/
MOUNTED EXTERN N 512 4096 1048576 51200 50742 0 50742 0 N FRA/
Node B lsdg仅显示DATA磁盘组
ASMCMD> lsdg
State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files Name
MOUNTED EXTERN N 512 4096 1048576 142976 50596 0 50596 0 Y DATA/
从Node B节点上ASM实例的动态视图查询显示正常:

原来是因为lsdg只列出已经mount的diskgroup，因为在Node B上FRA磁盘组没有mount所以不被列出，我本来以为是Bug造成的。 感谢Liqin Zhang网友的指出。
