Description | This article describes the issue where even with a license, more than 10 VDOMs can't be activated on some models in v7.4 or lower. |
Scope | FortiGate v7.4 or lower. |
Solution |
The number of available VDOMs can be seen with the 'get system status' command.
The procedure is described in this KB article: Technical Tip: How to activate a VDOM license from CLI
However, even with a license to have more than 10 VDOMs, most models do not support as many Virtual Domains. If the previous command is run, it will not be recognized by the FortiGate:
FGT # execute upd-vd-license XXX
This limit has been increased for some models since v7.6.1. From 10 to 25 for models in the 200-400 range, and from 10 to 50 for models in the 500-900 range: Changes in table size
With firmware lower than v7.6.1, it is not possible to increase the number of VDOMs in such FortiGate models, the license will not have any effect, and the command can't be run.
