VCSA and ESXi password security

I recently went looking for information on password security for the VCSA 6.0 & 6.5 and ESXi 6.0 & 6.5. Most specifically, I was interest in the number of passwords remembered, so I could define that in documentation for a client. Try as I might, I couldn’t find documentation for VCSA number of passwords remembered… Continue reading “VCSA and ESXi password security”

HPE Custom Image for ESXi 6.5U1 has been withdrawn due to purple-screen issues

HPE has quietly withdrawn the HPE Custom Image for ESXi 6.5U1 July 2017 due to purple-screen issues being experienced on a number of current VMware-supported servers (http://vmware.com/go/hcl)! The particular issue purple screen we saw when deploying this ISO against a HP BL460 G7 was: #PF Exception 14 in world 6824:sfcb-smx IP 0x1 addr 0x1  

OVF and OVA formatted Virtual Appliances

The Open Virtual machine Format (OVF) originally came about in 2007 as the result of a proposal by vendors (VMware, HP, Dell and others) to the Distributed Management Task Force (DTMF), the goal being to create an open standard for interchangeability (portability) of Virtual Machines between hypervisors. VMware was an early and enthusiastic adopter of… Continue reading “OVF and OVA formatted Virtual Appliances”

Patch your ESXi Hosts from the command line easily and quickly

UPDATED 4/18/2016: HP has a new URL for HP Customized VMware ISO’s and VIB’s For example: Prior to installing vCenter in a new cluster Standalone ESXi installations without a vCenter Server Hardware… Continue reading “Patch your ESXi Hosts from the command line easily and quickly”

Changing existing LUNs to Round Robin on ESXi

In the following steps, I am going to show you how to set all of the VMFS Volumes (LUNs) on an ESXi Host to use the PSP known as Round Robin, using only the ESXi Shell and/or SSH. This is clearly the simplest and most direct method of changing the PSP for existing volumes, and… Continue reading “Changing existing LUNs to Round Robin on ESXi”

Timekeeping on ESXi

Timekeeping on ESXi Hosts is a particularly important, yet often overlooked or misunderstood topic among vSphere Administrators. I recall a recent situation where I created an anti-affinity DRS rule (separate virtual machines) for a customer’s domain controllers. Although ESXi time was correctly configured, the firewall had been recently changed and no longer allowed NTP. As… Continue reading “Timekeeping on ESXi”

iSCSI with Jumbo Frames and Port Binding

Immediately after installing an ESXi Server, you may or may not have any storage at all. Most ESXi servers today are diskless, with the ESXi installation living on some sort of flash-based storage. In this case a fresh installation of ESXi will present with no persistent storage whatsoever, as you can see in the example… Continue reading “iSCSI with Jumbo Frames and Port Binding”

Using VMware Paravirtual devices

One of the most common oversights in vSphere deployments is a failure to use the Paravirtual drivers that VMware has provided us for networking and storage. On a physical platform, one chooses supported device(s) for networking and storage, and then installs the correct driver(s) to support those devices. For example; on a physical system, you… Continue reading “Using VMware Paravirtual devices”

Install ESXi 6 to a physical server with IPMI

We are going to install ESXi 6 on a physical server using HP’s IPMI interface known as iLO to perform the install. iLO is considered best-in-class for IPMI consoles, but still can take some getting used to. IPMI out-of-band interfaces collectively have the advantage of allowing users to: Power servers on and off Connect to ISO… Continue reading “Install ESXi 6 to a physical server with IPMI”
