Issue/Introduction

The vxdisk resize command enables the user to resize the size of a VxVM managed disk following a Dynamic LUN Expansion (DLE) event performed at the storage layer.

NOTE: The operating system (OS) must detect the revised size, before VxVM can resize the VxVM managed disk. The Veritas Dynamic LUN Expansion (DLE) feature can result in data corruption when resizing a single path GPT disk using vxdisk resize with InfoScale 7.4.2 and higher. The issue is applicable to all platforms; Solaris, Aix and Linux releases with VRTSvxvm 7.4.2.x and higher.
