Symptoms

Permissions on the LUN changes when the cluster node reboots. This resulting in the voting device accessibility issue and clusterware startup failure.

For example, original permission on the disks

root@racnode1 /devices/virtual-devices@100/channel-devices@200 # ls -la|grep e,raw

crw-rw---- 1 grid asmadmin 264, 244 Jun 25 21:53 disk@1f:e,raw

crw-rw---- 1 grid asmadmin 264, 252 Jun 25 21:53 disk@20:e,raw

crw-rw---- 1 grid asmadmin 264, 332 Jun 25 21:53 disk@2a:e,raw

crw-rw---- 1 grid asmadmin 264, 340 Jun 25 21:53 disk@2b:e,raw


After the node reboot:

root@racnode1 /devices/virtual-devices@100/channel-devices@200 # ls -la|grep e,raw

crw------- 1 root sys 264, 244 Jul 27 09:03 disk@1f:e,raw

crw------- 1 root sys 264, 252 Jul 27 09:03 disk@20:e,raw

crw------- 1 root sys 264, 332 Jul 27 09:03 disk@2a:e,raw

crw------- 1 root sys 264, 340 Jul 27 09:03 disk@2b:e,raw

Another symptom include, permission appears to be reset for non-USM devices after running 'acfsroot install' on Solaris
