Created ASM Stamped Disks But Unable To Create Diskgroup (Doc ID 437555.1)

Last updated on OCTOBER 28, 2016

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.1 and later
Microsoft Windows x64 (64-bit)

Symptoms

On a Windows 2003 machine, the new created partitions cannot be seen by the asmtoolg.
When a drive letter is assigned to the partitons (which is not what the documentation recommends),
the partitions are seen and they can be stamped as ASM disk. After this the disk groups can be created using DBCA or at ASM level.

The partitions were created by following the Note <<331796.1>>.

You are using a HP StorageWorks disk cabinet.
