Chapter 2: SHA Troubleshooting 2.2.39 Warning: Incorrect network configurations [Details: The IP addresses of active server and passive server in the high-availability cluster of the following network interfaces are not in the same subnet: LAN X] Warning Incorrect network configurations. Details: The IP addresses of My_Active_Hostname (active server) and My_Passive_Hostname (passive server) in the high-availability cluster of the following network interfaces are not in the same subnet: LAN X Suggestion: Go to Network to modify network settings. Description The IP addresses of the cluster interface LAN X on the active and passive servers are not in the same subnet. Once the service is switched over, services using LAN X may be affected. Cause The network cables of the active and passive servers are mistakenly connected to different subnets. Thus, each server obtains DHCP IP addresses from different network segments. Resolution • If LAN X is using DHCP IP, make sure that the network cables for LAN X on the active and passive servers are connected to ports belonging to the same subnet. Otherwise, you can edit the network settings on the DHCP server so that the IP addresses belong to the same subnet. • If LAN X is using a static IP, go to Synology High Availability > Network, select LAN X, and click Manage Network Interface. Then, click Configure Server Network and select Use manual configuration. You can then modify the network settings so that the IP addresses are in the same subnet. 2.2.40 Warning: Incorrect network configurations [Details: The gateway address of default gateway interface LAN X on the active server is not set.] Warning Incorrect network configurations. Details: The gateway address of default gateway interface LAN X on My_Active_Hostname (active server) is not set. Suggestion: Go to Network and set the gateway address for the default gateway interface LAN X on My_Active_Hostname (active server). Description The gateway address of default gateway interface LAN X on the active server is not set. Cause LAN X is set as the default gateway but the gateway address is not set. Resolution Go to Synology High Availability > Network, click Configure Server Network, and then fill in the gateway IP address for the active server. 37

Chapter 2: SHA Troubleshooting
2.2.39 Warning: Incorrect network configurations [Details: The IP
addresses of active server and passive server in the high-availability
cluster of the following network interfaces are not in the same subnet:
LAN X]
Warning
Incorrect network configurations.
Details
: The IP addresses of My_Active_Hostname (active server) and My_Passive_Hostname
(passive server) in the high-availability cluster of the following network interfaces are not in
the same subnet: LAN X
Suggestion
: Go to
Network
to modify network settings.
Description
The IP addresses of the cluster interface LAN X on the active and passive
servers are not in the same subnet. Once the service is switched over,
services using LAN X may be affected.
Cause
The network cables of the active and passive servers are mistakenly
connected to different subnets. Thus, each server obtains DHCP IP
addresses from different network segments.
Resolution
• If LAN X is using
DHCP IP
, make sure that the network cables for LAN X
on the active and passive servers are connected to ports belonging to the
same subnet. Otherwise, you can edit the network settings on the DHCP
server so that the IP addresses belong to the same subnet.
• If LAN X is using a
static IP
, go to
Synology High Availability
>
Network
, select LAN X, and click
Manage Network Interface
. Then,
click
Configure Server Network
and select
Use manual configuration
.
You can then modify the network settings so that the IP addresses are in
the same subnet.
2.2.40 Warning: Incorrect network configurations [Details: The gateway
address of default gateway interface LAN X on the active server is not
set.]
Warning
Incorrect network configurations.
Details
: The gateway address of default gateway interface LAN X on My_Active_Hostname
(active server) is not set.
Suggestion
: Go to
Network
and set the gateway address for the default gateway interface
LAN X on My_Active_Hostname (active server).
Description
The gateway address of default gateway interface LAN X on the active server
is not set.
Cause
LAN X is set as the default gateway but the gateway address is not set.
Resolution
Go to
Synology High Availability
>
Network
, click
Configure Server
Network
, and then fill in the gateway IP address for the active server.
