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. In the manual from Huawei is explained how to configure the settings with esxcli on the ESXi-Host. That’s fine, but not enough 😉 We want to configure this with PowerCli to easily manage more than one Host. #get esxcli $esxcli2 = Get-ESXCLI -VMHost (Get-VMhost MyHost-001) -V2 #show…

Got a PSOD? Check which VMs restarted by HA!
We design highly redundant Datacenters, Clusters, Storage Systems and even Networks, but in the end we still have some unplaned outages :/ This week we had a defect Memory DIMM that caused a PSOD on one ESXi Host.
