In 11gR2 you have also a script that you can use to reconfigure / reinitate the cluster (forgot the name, will try to find some details tomorrow). During one of it steps it will scratch the asm diskgroup on which the ocr / voting disks are located. So it is indeed good practice to put the vd / ocr files in a dedicated asm diskgroup, separated from the other db files. regards, Freek D'Hooge Uptime Oracle Database Administrator email: freek.dhooge@xxxxxxxxx tel +32(0)3 451 23 82 http://www.uptime.be disclaimer: www.uptime.be/disclaimer ________________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Harel Safra [harel.safra@xxxxxxxxx] Sent: 22 November 2010 21:40 To: andrew.kerber@xxxxxxxxx Cc: pnedeljkovich@xxxxxxxxxxxxxxx; Amaral, Rui; oracle-l@xxxxxxxxxxxxx Subject: Re: ASM disk corruption We have a dedicated disk group for ocr/voting that's just 1GB and doesn't contain data files. It made sense (to me at least...) to separate OCR from other data for later database cloning, etc. Harel Safra On 22/11/2010 21:39, Andrew Kerber wrote: > MOS recommendation was to use normal or high redundancy instead of > external.
