Symptoms

You have a working ASMLib configuration with multiple diskgroups.  You do not have a value set for asm_diskstring.  This results in it defaulting to ORCL:* After system maintenance is performed and the server is restarted your diskgroups will not mount with the errors listed below.  When you  check at the OS level the disks are listed in /dev/oracleasm/disks directory.  When you perform a listdisks command the disks appear listed.  You receive the error when you try to mount the diskgroups.  The errors presented indicate that we could not find a sufficient number of disks to mount the diskgroup.  The list of system patches below is only a representation and it could be the result of any library installation.
