I have a 2 node oracle rac with asm . I have to add new LUN to asm to increase space in asm disk group I have done the following on node1
Ran format
Created the partition on slice4 on the new device file corresponding to the LUN
Created the block and character device file like RAC_ORACLE_data_05 under /dev/dsk/oracle and /dev/rdsk/oracle (where the other device files used by ASM also reside) using the major and minor number of the new LUN
Changed the permissions to oracle:dba
The new LUN is now visible through the ASM on node 1 as RAC_ORACLE_data_05
My question is what steps I need to carry out on node 2 of the cluster
The disk is visible on node 2 as well
The disk is already showing up with the partitions as created through node 1
Do I have to create the device file under /dev/dsk/oracle with the major minor numbers as shown on node 2 for the LUN
TIA
