Re: Hung ASM Disk

Hi, alek

Probably, DBCA(Configuration Assistant) poor quality.

I had a similar problem ASM in Windows version.

After I de-configure ASM Group, re-configure new ASM group with same DISK parameter(Disk number and so on). It couldn't work.

Therefore I decided BREAK RAW device information. (We used RAID5)

After that, I could make ASM again.

Please you try breaking RAW information, if possible(don't software simulation)

Regards.
