Generating the default VVol Storage Container ID

A VVol datastore, is not a file system, so it is not a traditional datastore. It is just a capacity quota. So when you “mount” a VVol datastore, you aren’t really performing a traditional mounting operation as there is no underlying physical storage to address during the mount. So instead of mounting some storage device, you are mounting what is called a storage container. This is the meta data object that represents the certain amount of capacity that can be provisioned from a given array. An array can have more than one storage containers, for reasons of multi-tenancy or whatever.

In a VMFS world, when you go to create a new datastore, you pass it the serial number of the storage you want to format with VMFS. You know that serial, because, well, you created the storage device. When you “mount” a VVol datastore, instead of a device serial, you supply the storage container UUID. It comes in the form of vvol:e0ad83893ead3681-b1b7f56a45ff64f1. Of course the characters will vary a bit.

Increasing VMFS capacity with vRealize Orchestrator

I am working on adding some functionality to the FlashArray workflow package for vRealize Orchestrator and one of those features is automating the process to increase the capacity of a VMFS volume. The FlashArray potion of that is pretty straight forward but what of the VMFS portion? Not much on the internet directly about this. Luckily using the vCenter SDK with vRO, this is pretty easy.
