Lately, I’ve been doing a lot of work provisioning and decommissioning LUNs on some Fibre Channel arrays. As you all know, this process can be somewhat tedious when provisioning a new LUN on vSphere or removing said LUN. In the past, I would always use this PowerCLI command Get-VMhost -Cluster "Cluster1" | Get-VMHostStorage -Refresh This would first get all the ESXi hosts in the cluster “Cluster1” and then launch the refresh cmdlet on each host....
Today I was preparing some updates with VUM on Lenovo servers running vSphere 6.0. Things did not go as expected. While staging the patches I was greeted with this error. ERROR: The host returns esxupdate error code:15. The package manager transactions is not successful. Check the update Manager log files and esxupdate.log files for more details. Looking into the esxupdate.log file I could find the following entries: 2018-10-08T08:23:18Z esxupdate: 31744883: BootBankInstaller....
Last week I was moving some VMs for a client using Veeam Quick Migration. During the migration, I happened to stumble upon some strange behavior. The source VMs make up an Oracle RAC cluster, using shared VMDKs. One of the requirements for setting up shared VMDKs, using the multi-writer option, is that they are thick eager zeroed disks. When the VMs got to the other side, they wouldn’t boot. I figured something went wrong during the migration so I tried it again....
Today I got my shiny new host for the homelab. After installing ESXi, I noticed the 10 Gbit NICs weren’t being detected. After looking around a bit I found the drivers in the form of a VIB. Start by uploading the VIB to a datastore that is accessible to the host. Turn on the SSH service in the security section and fire up a session. Once connected run esxcli software vib install -v /vmfs/volumes/NAS1-iSCSI/net-ixgbe_4....
