Configure Huawei Ultrapath with PowerCli
The last days we got two new All-Flash Storage Systems. These systems can present LUNs in a Metro-Cluster fashion. So I got the challenge to configure the Storage Plugin UltraPath from Huawei.

HA restarted the VMs fine, but we want to know quickly which VMs restarted. Check out a PowerCLI one liner to find the restarted VMs!
