Delete a storage snapshot of an Oracle 19c RAC database using ASM diskgroups with Dell PowerMax.

In this post I am going to explore deleting a storage snapshot of an Oracle 19c RAC database created on a Dell PowerMax storage array.

This post is a companion to the video Dell PowerMax – Refresh a storage snapshot of Oracle RAC database. and a follow on from the blog post Create a storage snapshot of an Oracle 19c RAC database using ASM diskgroups with Dell PowerMax.

This blog post assumes some basic knowledge of PowerMax storage concepts. If you need a basic introduction please check out my PowerMax basics video.

These examples will use the Solutions Enabler command line method of managing the PowerMax, unlike the video which uses the Unisphere graphical interface.

Using EMC Powerpath with ASMLib

ASMLib is optional software to simplify the use of Automatic Storage Management (ASM) for Oracle databases on Linux.

ASMLib ensures consistent naming of devices across RAC clusters, and also maintains permissions on devices across reboots, a feature that was important until UDEV rules were added to Linux with the 2.5 kernel.

EMC Powerpath is an advanced multi-pathing host based solution that works with EMC arrays to intelligently load balance I/O across all available paths as well as provide fault tolerance by automatically re-routing traffic around failed paths. EMC Powerpath is significantly more powerful and robust that native Linux MPIO.
