Written By Christian Castagna (Administrator)

Updated at October 21st, 2025

→ Applies to: SynetoOS 4.4.0 and above running VMware ESXi 6.5.0 (build 13932383) and above

The update requires the entire physical host to be rebooted

IMPORTANT
It is recommended to backup VMware ESXi configuration before performing the update ("How to Backup/Restore Host Configuration in VMware ESXi")

 

Step 1. Power-off all VMs including SynetoOS and Syneto File Recovery

Step 2. Connect to VMware ESXi CLI (via SSH)

Step 3. Clear old configuration

echo "#!/bin/sh" > /etc/rc.local.d/local.sh
echo "exit 0" >> /etc/rc.local.d/local.sh

 

Step 4. Move to your datastore deployment folder (replace <datastore> with your datastore/folder name)

cd /vmfs/volumes/<datastore>/deployment

EXAMPLE

cd /vmfs/volumes/datastore1/deployment

 

Step 5. Modify firewall rules to allow subsequent activities

esxcli network firewall ruleset set -e true -r httpClient

 

Step 6. Set Intel drivers to native

esxcli system module set --enabled=true --module=igbn

 

Step 7 (optional, for server Dell only). Enable kernel module

esxcli system module set --enabled=true --module=vmw_ahci

 

Step 8. Download Syneto VMware ESXi 6.7.0 (build 17499825)

wget -O esx-syneto-update.zip https://storage.googleapis.com/syneto_public_files/updates/ESXi-Upgrade-Bundles/ESXi6/ESXi-6.7.0-20210204001-Syneto-v6.105-release.zip

 

Step 9. Install the update (replace <datastore> with your datastore/folder name)

esxcli software vib install -d /vmfs/volumes/<datastore>/deployment/esx-syneto-update.zip

EXAMPLE

esxcli software vib install -d /vmfs/volumes/datastore1/deployment/esx-syneto-update.zip



EXAMPLE OUTPUT
