we have a RAC system with LUNS attacjed to both nodes we have created ASM aliases using major and mainor number..
ASM1 till ASM 10 are correctly showing the major minor numbers in both nodes...
and everything is running fine..
and this is best practice by IBM and ORACLE.
but we have a new Jr SA who is saying this is wrong as although major and minor are the same for each LUN on both Nodes the Lun Serila number is different.
we know that the configuartion is correct.
but how LUN serial could be different and major minor are identical?
