there is a need to access either node before the HA configuration is complete, use the serial number of each node as the
password.
Steps
1. Verify the certificate subject name on the primary node.
Run the following command:
adminaccess certficate show
sysadmin@dd9900-ha3a#
adminaccess certificate show
Subject Type Application Valid From Valid
Until
-------------------------- ---- ----------- ------------------------
------------------------
dd-ha3a.example.com host https Tue Aug 8 14:11:28 2018 Sat Aug 7
21:11:28 2022
dd-ha3a.example.com ca trusted-ca Tue Aug 8 21:04:53 2018 Mon Aug 7
21:04:53 2024
-------------------------- ---- ----------- ------------------------
------------------------
2. Verify the certificate subject name on the standby node.
Run the following command:
adminaccess certficate show
sysadmin@dd9900-ha3b#
adminaccess certificate show
Subject Type Application Valid From Valid Until
-------------------------- ---- ----------- ------------------------
------------------------
dd-ha3b.example.com host https Tue Aug 8 15:11:28 2018 Sat Aug 7
22:11:28 2022
dd-ha3b.example.com ca trusted-ca Tue Aug 8 22:04:53 2018 Mon Aug 7
22:04:53 2024
-------------------------- ---- ----------- ------------------------
------------------------
3. Complete one of the following options:
●
If the values in the
Subject
column on both nodes are different, continue to Step 4.
●
If the values in the
Subject
column on both nodes are the same:
a. Change the hostname of the standby node.
b. Run the
adminaccess certificate generate self-signed-cert regenerate-ca
command on the
standby node to generate new certificates with the new hostname.
c. Proceed to Step 4.
4. Set the system time on both nodes. The HA configuration will fail if the time on the two nodes is more than 10 seconds
apart.
Run the following command:
system set date MMDDhhmm [[CC] YY]
NOTE:
After HA configuration is complete, point both nodes to an NTP or Active Directory time server.
5. Turn off DHCP for each port used for the HA interconnect on both nodes.
HA interconnect ports
ethMc, ethMd
Run the following command:
net config
<HA-interconnect-port>
dhcp off
6. On the primary node, create the HA pairing.
NOTE:
●
Specify the hostname or the IP address of the standby node.
●
The
ha create
command will fail if one node is configured to use DHCP and the other node is configured to use
static IP addresses. Both nodes must use the same method to configure IP addresses.
Run the following command:
ha create peer {
<ipaddr>
|
<hostname>
} [ha-name
<ha-system-name>
]
