Welcome to November!  For those of us in the midwest this means a

nearly endless need to rake and bag leaves.    The first round isn’t so bad.  When you get to the 5th round or later – not as fun ?  Wherever you are – I hope you are well!  Please send me a kind thought as I prepare for my 6th round of leaf duty.  On to more interesting topics – this month’s newsletter contains a number of links that will help you start to prepare for vSphere 8

If you haven’t upgraded to vSphere 7 yet – there is still time. While vSphere 6.5 and 6.7 have left End of General Support and are now in Technical Guidance, VMware will still do their best to help you if you upgrade.    Take a look at these upgrade planning tips and get started!

vCenter Server Certificate Status Alarm

byArron King 09.16.2022 Certificates VCSA

Earlier this week I began receiving alarms from my vCenter regarding a Certificate Status Alarm.  I had not run into this particular error before and it took me a bit of investigation to get it solved.

An unusual certificate description

The alert kept repeating on an hourly interval and I didn’t have a clue what this certificate was for:

This email is to notify you that an alarm has been triggered in your vCenter:
[Critical] Alarm alarm.CertificateStatusAlarm on Folder Datacenters because Certificate 'CN=Synology,OU=Synology,O=Synology,L=Unknown,ST=Unknown,C=Unknown' from 'SMS' expires on 2022-08-01 08:35:11.000.

Alarm name alarm.CertificateStatusAlarm
Description alarm.CertificateStatusAlarm
Target Folder Datacenters
Status Critical (previous status: Unset)
Triggered time 09/15/2022 08:45:42 PM

Adding VMware Tools Updates to vSphere Lifecycle Manager

byArron King 08.24.2022 VMware Tools

Updated – 12/28/22 – based on user feedback I have updated this article.

There are times where VMware Tools updates are published outside of a vSphere release/update.  This can be due to a bug fix or a security advisory (ie: VMSA-2022-0024)

This new VMware Tools package can be easily added to your ESXi hosts so your virtual machines can be updated.  If you are still running vSphere 6.x, the VMware Tools package will be  updated using Update Manager.

vSphere 7 introduced Lifecycle Manager which can now be used for this update.  Here are the steps:

Login to vCenter, and navigate to Lifecycle Manager (click on the hamburger menu -> Lifecycle Manager)

Create the Baseline

Click on the Baselines menu and click New -> Baseline

Create New Baseline - Menu

vCenter Server Backup – Failed to create backup directory on Backup Server

byArron King 08.15.2022 VCSA

I noticed an alarm in vCenter that indicated the vCenter Server Appliance (VCSA) was having trouble backing up.  I logged into the VCSA Appliance Management interface (vCenter URL with :5480) to investigate.  When I logged in, I found the following error:

Failed to create backup directory on Backup Server

vcsa backup - failed to create directory

Thinking there was something wrong on my SFTP server, I checked the username and password, file system permissions; but could find nothing wrong. I connected to the VCSA using root on SSH, and checked the log file at /var/log/vmware/applmgmt/backup.log.  This provided some additional detail on the issue and showed the backup process was unable to authenticate to the SFTP server.

VCSA backup.log - failed to authenticate

 

 

 

I tried the SFTP command manually and found the core of the issue:

VCSA - SFTP command requires acceptance of SSH key

 

 

 

For some reason, the SSH key has changed and needs to be updated in the local SSH Known Hosts file.  Once I accepted this new key, the backup was able to complete successfully.

VCSA Backup Completed

 

 

 

 

I am not sure what would have changed the SSH key.  The only thing I can think of is that I had updated vCenter from 7.0 U3f to 7.0 U3g recently.  I have verified the host is correct.

DRS in Maintenance Mode feature not supported by license

byArron King 06.17.2022 vSphere

I was helping a customer with a question they ran into after upgrading from vSphere 6.7 to 7.0 U3.  Their VMware vSphere environment upgrade was complete. They had just upgraded their licenses in the VMware Customer Connect portal.  When they applied these license keys to their vSphere hosts

DRS in Maintenance Mode License Validation Warning

they received a warning that the DRS in Maintenance Mode feature was not supported with their vSphere Enterprise Plus license.

This made me dig into my memory banks a bit and I wanted to document it so I would remember.  Maybe it will help a few others along the way…

vSphere License Keys and Upgrades

vSphere upgrades from 6.5 to 6.7 or 7.0 to 7.0 U3 are considered “point upgrades” and do not require license key upgrades

Major upgrades (from 6.x to 7.x) do require license key upgrades.

Major Upgrades and VMware Licenses

When you perform a major upgrade in vSphere, the installer triggers a short Evaluation mode that provides customers time to login to the Customer Connect portal and update license keys.

These Evaluation mode licenses include every feature available.  When a new license key is applied, and there are features that will not be supported by the license,  a prompt appears informing customers of any features that will not be available when the new license key is applied.

DRS in Maintenance Mode

DRS in Maintenance Mode refers to a feature released in vSphere 6.7 U2 for the ROBO Enterprise edition of vSphere.  This feature:

  • Automatically migrates VMs to other hosts when it enters maintenance mode
  • Creates VM-Host affinity rules.  These rules are used to automatically move the VMs back to the original host when it exits maintenance mode

vSphere Enterprise Plus licenses include the DRS and Maintenance mode capabilities.  DRS in Maintenance Mode is a separate feature entirely and this prompt can be safely ignored.
