2. Verify the certificate subject name on the standby node.
Run the following command: adminaccess certficate show
sysadmin@dd9910-ha3b# adminaccess certificate show

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.
Table 41.
HA interconnect ports 
HA interconnect ports
eth7a, eth7b, eth7c, eth7d
Run the following command: net config <HA-interconnect-port> dhcp off
6. Create the HA pairing.
NOTE:
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.
● If preserving an existing hostname is required, set the hostname on each node and then create the HA system with the
HA system name:
a. Run the net set hostname command on the primary node.
net set hostname mysystem-n0.emc.com type local
b. Run the net set hostname command on the standby node.
net set hostname mysystem-n1.emc.com type local
c. Run the ha create command on the primary node.
NOTE: Specify the hostname or the IP address of the standby node.
ha create peer mysystem-n1.emc.com ha-name mysystem-ha.emc.com
● If preserving an existing hostname is not required:
Run the following command: ha create peer {<ipaddr> | <hostname>} [ha-name <ha-system-name>]
