Dear All,

I am in process to install Oracle 11g R2 (11.2.0.2) RAC on two node cluster (virtual) and progressed nicely till i face this asm disk check error. At the time of cluster verification i see the alert that "device checks for asm - failed". I installed 11g RAC before and did not see this error. Upon digging i see metalink note [ID 1210863.1]which says it is a bug but.

Does anyone have faced this error yet? Please share your thoughts on this error. I am attaching a screenshot of the error.

When you say that you had previously installed 11g RAC, was it on the same machines? If so, did you do something to clean the headers off of the ASM disks you are trying to re-use? 'dd if=/dev/zero of=<asmdisk> bs=1024 count=10000' on your ASM disks should take care of it Wink If these are new disks, make sure your permissions are set correctly Wink

No, It is another installation. I have done 3 installation of 11g before but didn't see this error. Later on in the installation we found some I/O error while copying oracle binaries on remote node. our storage guys looking into it.
