vSphere: Presenting Physical Disks to a VM

KB ID 0001563 Problem I’m doing some work presenting StarWind vSAN into VMware ESX. Because we also want ‘disk tiering’ it has to be ran from Microsoft Windows with Storage Spaces*. To do that I needed to present the physical disks in the ESX hosts, (HP DL380 Gen 10s) to the Windows Virtual Machines that StarWind will be running on. *Note: At present, ‘tiering’ cannot be done from the StarWind Linux...

Veeam: Restore/Migrate vSphere VM to Hyper-V

KB ID 0001559 Problem I saw this question asked on EE the other day, and while I’ve done Migrating from vSphere to Microsoft before, I’ve never really tried with Veeam. Migrating and Restoring vSphere Machines to Azure is easy, but what about Hyper-V? Solution Natively with Veeam Backup and Restore, the only way to do this, is to perform an Agent Based backup of your VMware VM. If you are unfamiliar with doing this,  you...

VMware: Fiber Channel HBA Reports Wrong WWN?

KB ID 0001534 Problem I was building some new ESX 6.7 U1 (HPE) servers this week, they had Emulex Fiber HBA’s in them. When it came to ‘allowing’ them access to the SAN, I went to get the Port World Wide Name; And was presented with this; Not only is that 19 Characters long, and not 16 characters, but BOTH VMHBA’s WERE THE SAME! Like MAC addresses they should be unique? So I’m guessing this is a bug....

Disable ATS Heartbeat

KB ID 0001529 Problem After ESX 5.5 Update 2, VMware added ATS Heartbeat.Some vendors, (like HPE SureStore and VSA) recommend that this is disabled. I can’t find any info about whether it’s safe to do this in production, so to be on the safe side I placed the hosts in maintenance mode first. Enter Maintenance Mode Use the following command; vim-cmd /hostsvc/maintenance_mode_enter Disable ATS Heartbeat Use the following...

Virtual SAN: Suppress ‘Datastore Usage on Disk’ Alarm

KB ID 0001527 Problem While deploying a HPE StoreVirtual VSA this week. We noticed all the local Datastore were showing an ‘Alarm’. If you are unfamiliar with Virtual SANs, then you give all the LOCAL Storage to them, which then gets ‘aggregated’ and provided back to the host(s) as fault tolerant clustered storage, like so; Which is great, but the VMware hosts just see that their LOCAL Datastore(s) are full,...
