l
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>]
Note: If no value is specified for the optional ha-name parameter, the ha create
command promotes the primary node hostname to be the HA system name.
ha create peer mysystem-p1.emc.com
This command:
l
Reboots both nodes, and completes the HA pairing when the nodes come back online.
l
Assigns node 0 the local hostname
<HA-system-name>
-p0.
l
Assigns node 1 the local hostname
<HA-system-name>
-p1.
7. When both nodes are up, verify the following information matches on both nodes:
l
Hardware model
l
Software version
8. Check the system for alerts.
Run the following command:
alerts show current
If the system displays System is misconfigured, the SSDs were not removed from the
front of the primary node. Run the enclosure show misconfiguration command to
get more details.
9. Verify the HA status
Run the following command:
ha status
HA System Name: dd9900-ha3a.emc.com
HA System Status: highly available
Node Name Node ID Role HA State
-------------------------- --------- --------- --------
dd9900-ha3a-p0.example.com 0 active online
dd9900-ha3a-p1.example.com 1 standby online
-------------------------- --------- --------- --------
10. On node 0, convert all data IP addresses to floating IP addresses.
Run the following command for each IP address that needs to be converted to a floating IP
address:
net config <interface-name> <IP address> netmask <netmask> type
floating
Note:
The
net config
command with the float option is the only way to configure a floating IP address. There
is no method available in DD System Manager to configure a floating IP address.
# net config eth1a 2.2.2.1 netmask 255.255.255.0 type floating
11. Add the SSD enclosure to cache tier.
Run the following command:
storage add tier cache enclosure
