ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15075: disk(s) are not visible cluster-wide
ORA-15080: synchronous I/O operation to a disk failed





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. 

 




15080, 00000, "synchronous I/O operation to a disk failed"
// *Cause: A synchronous I/O operation invoked on a disk has failed.
// *Action: Make sure that all the disks are operational.
