Hi , I have a test RAC setup. htsscsun06 - Netapp Filer htssclin5 - RAC node 1 htssclin4 - RAC Node 2 I had this RAC setup working fine , but because I had to relocate the boxes we had to power off. After that the disks are not getting mounted as needed - and gives out an error indicating the devices are not shared. partition lin4 lin5 ocr /dev/sdb /dev/sdc ebs /dev/sdc /dev/sde udevinfo command did not show any UUID , however cluster.conf did. How do I fix the problem. Regards Chandra
