ORA-15032和ORA-15075: disk（s） are not visible cluster-wide

在为ASM添加磁盘组添加磁盘扩展空间时，遇到以下错误SQL> alter diskgroup data add disk "/dev/rhdisk12";alter diskgroup data add disk "/dev/rhdisk12"

ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15075: disk（s） are not visible cluster-wid看一下 ORA-15032 和ORA-15075 的错误解释[Oracle@mhxy162 ~]$ oerr ora 1503215032, 00000, "not all alterations performed"
// *Cause: At least one ALTER DISKGROUP action failed.
// *Action: Check the other messages issued along with this summary error.
//
[oracle@mhxy162 ~]$ oerr ora 15075
15075, 00000, "disk（s） are not visible cluster-wide"
// *Cause: An ALTER DISKGROUP ADD DISK command specified a disk that could
// not be discovered by one or more nodes in a RAC cluster
// configuration.
// *Action: Determine which disks are causing the problem from the
// GV$ASM_DISK fixed view. Check operating system permissions
// for the device and the storage sub-system configuration on
// each node in a RAC cluster that cannot identify the disk.
ORA-15075 提到"Check operating system permissions for the device" ，可以通过gv$asm_disk 查看。记得修改/dev/rhdisk12文件的属组为grid:oinstallls -l /dev/rhdisk12
