Failed to match the block device "{0}" with the new default discovery string

Cause

The specified block device could not be discovered with the new default discovery string. Starting in 12g the default ASM disk discovery string was changed from '/dev/raw/raw*' to '/dev/sd*'. To ensure proper upgrade of ASM, all disks that were member disks of diskgroups prior to upgrade must continue to be discovered as member disks after upgrade.


Action

Make sure that the specified devices are discoverable using the new default discovery string (this will be necessary in the long run because raw devices are being deprecated). Alternatively set the disk discovery path to '/dev/raw/raw*' using the command 'asmcmd dsset --normal discovery string' in ASM 11.2 or later. If SPFILE is in use for 11.1 or earlier ASM, then use the command 'ALTER SYSTEM SET ASM_DISKSTRING=discovery string SCOPE=SPFILE;'. Otherwise, update the value of parameter ASM_DISKSTRING in the PFILE of each ASM instance.
