Greetings,
I hope this isn't a naïve question but anyway, I am using ASM on a two node RAC
cluster, Oracle 10.2.0.3.0 SE on Red Hat EL4. The raw devices look like this...
crw-rw---- 1 root dba 162, 1 May 6 14:45 /dev/raw/raw1
crw-rw---- 1 oracle dba 162, 10 May 6 14:45 /dev/raw/raw10
crw-rw---- 1 oracle dba 162, 11 May 7 10:36 /dev/raw/raw11
crw-rw---- 1 root dba 162, 2 May 6 14:45 /dev/raw/raw2
crw-r--r-- 1 oracle dba 162, 3 May 6 14:45 /dev/raw/raw3
crw-r--r-- 1 oracle dba 162, 5 May 6 14:45 /dev/raw/raw5
crw-r--r-- 1 oracle dba 162, 6 May 6 14:45 /dev/raw/raw6
crw-rw---- 1 oracle dba 162, 7 May 6 14:45 /dev/raw/raw7
crw-rw---- 1 oracle dba 162, 8 May 6 14:45 /dev/raw/raw8
crw-rw---- 1 oracle dba 162, 9 May 6 14:45 /dev/raw/raw9
I know which are used for the CRS and voting disks but I am trying to determine
which of the others make up the ASM disk groups and I can't find information on
how to do that. The disk groups have been provisioned using asmlib. Querying
v$asm_disk returns the following...
SQL> select group_number,name,substr(path,1,30) from v$asm_disk;
GROUP_NUMBER NAME SUBSTR(PATH,1,30)
------------ ------------------------------ ------------------------------
0 /dev/raw/raw10
0 /dev/raw/raw9
0 /dev/raw/raw8
0 /dev/raw/raw7
0 /dev/raw/raw6
0 /dev/raw/raw5
0 /dev/raw/raw3
0 /dev/raw/raw11
0 /dev/raw/raw1
0 /dev/raw/raw2
1 VOL1 ORCL:VOL1
1 VOL2 ORCL:VOL2
2 VOL3 ORCL:VOL3
For example which of the raw devices are mapped to VOL1? I suspect I am not
understanding something or else just have not found the appropriate view to
query but if someone can help me out I would be most appreciative.
Thanks.
