This section highlights some of the operational changes that administrators should be aware of in 6.4.0.
Citrix XenServer limits ramdisk to 128M by default. However the FMG-VM64-XEN image is larger than 128M. Before updating to FortiManager 6.4, increase the size of the ramdisk setting on Citrix XenServer.
- On Citrix XenServer, run the following command:
xenstore-write /mh/limits/pv-ramdisk-max-size 536,870,912
- Confirm the setting is in effect by running
limits = ""
pv-kernel-max-size = "33554432"
pv-ramdisk-max-size = "536,870,912"
boot-time = ""
- Remove the pending files left in
The ramdisk setting returns to the default value after rebooting.
Currently, there is no ADOM upgrade option for ADOM version 6.2 to move to version 6.4. It also means that ADOMs with version 6.2 cannot properly support FortiGates running 6.4. In order to manage FortiGates running 6.4, add them to a 6.4 ADOM.
Prior to using the FortiManager to push a multi-step firmware upgrade, confirm the upgrade path matches the path outlined on our support site. To confirm the path, please run:
dia fwmanager show-dev-upgrade-path <device name> <target firmware>
Alternatively, you can push one firmware step at a time.
A Hyper-V FMG-VM running on a PC with an AMD CPU may experience a kernel panic. Fortinet recommends running VMs on an Intel-based PC.
Due to known vulnerabilities in the SSLv3 protocol, FortiManager-VM64-AWS only enables TLSv1 by default. All other models enable both TLSv1 and SSLv3. If you wish to disable SSLv3 support, please run:
config system global
set ssl-protocol t1sv1
