•
Confirm that each 7700 FSP Controller SCI0 port has IP network access to its HA partner (the
other 7700 FSP Controller). This access can be in the form of direct connect or WAN access
(direct connect access is only for non-stretched cluster configurations).
Confirm that all ports being added to the HA configuration have link UP status, management
with eth0, sci0, and rep0 (if replication is supported or being added), Fibre Channel northbound
and southbound, and iSCSI ports.
Select one 7700 FSP Controller in each HA pair to act as the primary. Configure and enable HA
from the primary 7700 FSP Controller. The
enableha
command applies settings that have
been saved in a configuration file at /usr/local/concerto/etc/ha_precfg.ini.
Note:
Changes that are made to network configuration require that HA be disabled, the
ha_precfg.ini
file needs to be updated, and HA re-enabled. To make changes, use
cfghaprecfg.sh
to edit the
ha_precfg.ini
file. For details, see
Completing the HA Configuration File
•
Collect the configured and assigned IP addresses for both 7700 FSP Controllers. Inspect local
physical interfaces and current IP address assignments using the
ifconfig -a
command.
Use the
ethtool
command to inspect the current link and interface attributes. The
ha_precfg.ini
file format provides a single line for each attribute. Apply attributes in the
same sequence as the interface is listed:
Note:
Typically, 7700 FSP Controller A is the primary and 7700 FSP Controller B is the
secondary.
a.
sci_ip
—This is the Storage Cluster Interface (SCI) IP address; there is an
sci0
IP
address on each 7700 FSP Controller.
b.
ipmi_ip
—This is the IPMI or iDRAC IP address that allows virtual control and power
management access; this IP address must be accessible from
heartbeat_ip
and the
virtual_ip
.
c.
interface
—This is the Ethernet interface (
eth0
), and this setting can also list other
configured interfaces.
d.
heartbeat_ip
—This is the heartbeat monitor IP address that is assigned to the server
by network IT/network administrator, and is used for monitoring HA availability.
e.
virtual_ip
—This is the virtual or management IP address assigned to a 7700 FSP
Controller (and associated with
eth0
before HA is enabled). Once HA is enabled, this IP
address is re-assigned to
eth0:1
on each 7700 FSP Controller.
f.
rep0
—This is interface port number configured for or associated with replication (the
7700 FSP storage cluster supports two dedicated replication ports,
rep0
and
rep1
).
g.
iSCSI ports
—These are the configured iSCSI interface ports (for example,
isc0
,
isc1
,
isc2
, and
isc3
).
•
This following is a sample
ha_precfg.ini
file for a local storage cluster with SCI ports
directly connected with the following attributes:
— a network IP address of 169.254.0.0/24
— a management network IP address of 10.5.4.0/24
— a replication network IP address of 172.16.1.0/24
