Oracle Database Discussions

I have a two-node Oracle 10gR2 RAC configuration using raw disks. Basically, raw disks are used for CRS's OCR/voting disks, ASM's ASM spfile and disk groups.

Is there a better way to figure out what raw disks are configured in Oracle using methods other than those shown below:

- To find out votedisk:
# crsctl query css votedisk
0. 0 /dev/ora_crs_vote1
1. 0 /dev/ora_crs_vote2
2. 0 /dev/ora_crs_vote3

- To find out OCR:
# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 525836
Used space (kbytes) : 3856
Available space (kbytes) : 521980
ID : 1603037329
Device/File Name : /dev/ora_ocr_file1
Device/File integrity check succeeded
Device/File Name : /dev/ora_ocr_file2
Device/File integrity check succeeded

Cluster registry integrity check succeeded

- Is there a way to figure out what disk device is used for ASM spfile?

- To find out raw disks configured for disk groups:
while connected to the ASM instance in sqlplus:

SQL> select name,path from v$asm_disk where name like 'DG%';
