When implementing new storages or configure existing ones it is a good idea to check paths (state and amount) to volumes. When operating a few hosts using a few datastores this can be a very time-consuming task when using the GUI. Therefore I wrote the following function.
Script to check if VMs part of DRS-Groups
Recently I needed to check, if every VM of a cluster is part of at least one DRS-VM-Group. Typically this is a useful check if you operate a two (or more) site datacenter and/or stretched cluster. You then create DRS-groups for VMs and hosts. For each site a host- and at least a VM-group. At creation time of groups, every VM will be added to […]
4 ways to configure adv. settings in CLI
There are a few CLI methods to configure advanced settings in ESXi Hosts. It depends on where you are (vMA/Linux, Windows Client, Console) and what you want to do (configure all hosts or just a specific host, …) which option fits best.

There are a few best practices when implementing a 3PAR into a vSphere environment. One of these is the creation of a custom PSP-rule. With this set, all 3PAR volumes are automatically configured according to best practices when they get mounted. In this post I will show ways to create this rule. [Update] Because HPE Primera uses same vendor and model description as 3PAR, the […]
