When using OracleASM in normal or high redundancy, a failed disk is nothing to be concerned with. However, when using AFD, there are several additional actions you need to take into account in order to replace the disk quickly and easily. It is imperative to understand that when using AFD, there are some unavoidable tasks…
A nice and informative note about how to obtain OracleASM attributes, including “hidden attributes” can be found here.

I came across a Linux host (RHEL6.2) which I was not the one managing before, which required adding a node in Oracle 11.2 Grid Infrastructure. According the common documentations, as can be seen here, after cloning the host (or installing it correctly, according to Oracle requirements), you should run ‘cluvfy’ on the existing cluster node….

There are many sites explaining how to install Oracle GI 12.2, however, there are some special tricks which can simplify GI installation. For once, when installing GI and then installing the huge PatchSet (which is usually around 1.4GB in size) – it takes time. A lot of time. A simple but not very well documented…
