ASMLIB Disk Discovery troubleshooting checklist
In Oracle10g, storage management and provisioning for Oracle databases is more simplified with a new feature called Automatic Storage Management (ASM).
In order to simplify the operating system to database interface, and to exploitthe capabilities and strengths of vendors’ storage arrays, the ASM API was developed.
The scope of the ASM API (ASMLIB), which is an add-on to ASM, is providing an alternative interface for the ASM enabled-Oracle kernel to identify and access
Oracle provides an ASM library driver for the Linux OS. With this library the steps of raw device binding become unnecessary. This ASM library driver must
be installed prior to installing any other Oracle database software. Additionally, it is recommended that any ASM disk devices required by the database be prepared
and created before the OUI database install.
This note, which is specifically geared towards the Oracle ASMLIB on Linux, will address disk discovery issues than can occur either at disk group database creation;
e.g. when using DBCA, or creating disk groups manually.
The following checklist is intended to be a top-down list of items to review and validate, when performing the install of AMSLIB.
