Have an Oracle installation with ASM used to manage. I am in need of defining the underlying RAW file system that the DB files reside on. I have issued the following command “show parameter asm_diskstring"
but, it points to the /dev/oracleasm/disks/* which contain files of BLOCK type. This are not the REAL files. How do I itenfify the underlying RAW file system. I have suggested a query will this give me what I need :
[root@orcldb2 ~]# /etc/init.d/oracleasm querydisk DATA01
Disk "VOL1" is a valid ASM disk on device [8, 97]
[root@orcldb2 ~]# ls -l /dev | grep 8, | grep 97
brw-rw---- 1 root disk 8, 81 Nov 4 13:02 sdg1
asm_diskstring='/dev/oracleasm/disks/*'
SELECT NAME,PATH FROM v$asm_disk;
NAME PATH
