Storage System Administrators will often come across situations like collecting disk information and generating reports. In most of the situations management GUI won't provide much help and you will end up using CLI to collect system related information .
In this article, we will explore the possibility of collecting HP StoreServ (3PAR) vlun information using CLI commands which will help you to identify the 3PAR vluns without much hassle. Basically, to achieve this, we use 2 commands from CLI set, those are showvv and showvlun.
The command showvv displays the information about virtual volumes (VVs) in the system while showvlun displays information about VLUNs in the system.
virtual volumes(vvols) are basically the data layer which can be assigned to a host and vlun is the exported form of a virtual volumes and gets the association between vvol and LUN.
Let's see the syntax and options for these commands,
showvv can be used to display information about all virtual volumes or specific virtual volumes in a 3PAR system and you can fine tune the command to get what you need.
basically, we use couple of options to display the volume information like, volume ID, CPG etc
showvv when used with option -d will display detailed information about the virtual volumes. The output will show parent ID and attributes like child volume ID and remaining blocks for snap creation etc.
3parlab01 cli% showvv -dWhen used with -cpgalloc, the output will show CPGs associated with each virtual volume.
