The permissions for block devices "{0}" are incorrect on node "{1}" [Expected = {2} octal, Actual = {3}]

Cause

The permissions of the indicated block devices were incorrect on the specified node. Starting in 12g the default ASM disk discovery string was changed from '/dev/raw/raw*' to '/dev/sd*'. The disks corresponding to the block device files in the message were members of ASM disk groups and were accessed using the raw devices (matched by '/dev/raw/raw*' prior to 12g) with the correct permissions. However, the block devices in the message corresponding to the same disks and found with '/dev/sd*' do not have the correct permissions. To ensure continued working of ASM, all disks that were members of disk groups must continue to be members.


Action

Make sure that the permissions for the specified block devices matches the expected value (this will be necessary in the long run because raw devices are being deprecated). Alternatively set the string '/dev/raw/raw*' as the disk discovery path using command 'asmcmd dsset --normal discovery string' in ASM 11.2 or later, using command 'alter system set asm_diskstring=discovery string scope=spfile;' in 11.1 or earlier ASM.
