Add Additional Disk Space to the VM-Series Firewall
The VM-Series firewall requires a 60GB virtual
disk, of which 21GB is used for logging, by default.
large deployments, use Panorama to aggregate data from all next-generation
firewalls, and provide visibility across all the traffic on your
network. Panorama provides centralized logging and reporting.
In smaller deployments where you do not use Panorama, you
can add a new virtual disk to increase log storage capacity. The
new virtual disk can support 60GB to 2TB of storage capacity for
logs. This task is described below.
When the virtual
appliance is configured to use a virtual disk, the VM-Series firewall
no longer stores logs. If the appliance loses connectivity to the
virtual disk, logs can be lost during the failure interval. If necessary,
place the newly created virtual disk on a datastore that provides
RAID redundancy. RAID10 provides the best write performance for applications
with high logging characteristics.
Power off the VM-Series firewall.
On the ESXi server, add the virtual disk to the firewall.
Select the VM-Series firewall on the ESXi
to launch the Add
Hardware wizard, and select the following options when prompted:
the hardware type.
Create a new virtual disk
as the virtual disk type.
In the location field, select
Store with the virtual
. The datastore does not have to reside
on the ESXi server.
Verify that the settings look correct and click
exit the wizard. The new disk is added to the list of devices for the
Power on the firewall.
Powering on the firewall initializes the virtual disk for
first-time use. The time that the initialization process takes to
complete varies by the size of the new virtual disk.
the new virtual disk is initialized and ready, PAN-OS moves all
logs from the existing disk to the new virtual disk. New log entries
are now written to this new virtual disk.
PAN-OS also generates
a system log entry that records the new disk.
you reuse a virtual disk that was previously used for storing PAN-OS
logs, all logs from the existing disk are overwritten.
Verify the size of the new virtual disk.
In the Logging and Reporting Settings section, verify
displays the new disk capacity.
