Hello,
 

11.2.0.2 on 2 node AIX RAC.
 

I've got a single voting disk as per below.
 
 crsctl query css votedisk

##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------

 1. ONLINE   597a4cd2ecc84fe1bfe8eaf5520b3de7 (/dev/ora_asmsys_disk01) [ASMSYS]
Located 1 voting disk(s).
 

Also i've also got a single OCR file as below.
 

ocrcheck

Status of Oracle Cluster Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     262120
         Used space (kbytes)      :       3188
         Available space (kbytes) :     258932
         ID                       :  764672799
         Device/File Name         :    +ASMSYS
                                    Device/File integrity check succeeded
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
         Cluster registry integrity check succeeded
         Logical corruption check bypassed due to non-privileged user
 

home/grid > cat /etc/oracle/ocr.loc
ocrconfig_loc=+ASMSYS
local_onlyúLSE

 

The ASMSYS  diskgroup  is set to for EXTERNAL REDUNDANCY.
 

select NAME,TYPE,COMPATIBILITY,DATABASE_COMPATIBILITY,VOTING_FILES from  v$asm_diskgroup where name = 'ASMSYS';

NAME                           TYPE   COMPATIBIL DATABASE_COMPATIBILITY                                       V
------------------------------ ------ ---------- ------------------------------------------------------------ -
ASMSYS                         EXTERN 11.2.0.0.0 10.1.0.0.0                                                   Y

 

My question is do  I have a single point of failure here. Am not sure what my RAID configuration is and therefore what level of redunancy the RAID is giving me.
 

Should I be adding extra voting disks and OCR to this setup. Any suggestions greatly appreciated.
