Replace the secondary interconnect in a DS-V3 configuration
Complete these steps to replace the secondary interconnect in a DS-V3 configuration.
Before you begin:
ThinkAgile Advantage Support: Request Support to retrieve the following interconnect settings from the
Cloud Controller database:
•
appliance_serial_number
,
controller_uuid
, hypervisor network settings, uplink network settings, and the
Network Controller Services version running on the interconnect
• the reserved VLAN IDs (Hardware management network, MLAG/ISL, Hypervisor, Uplink)
• the
peerServiceTag
of the primary interconnect
Procedure performed by
: customer or field service, Lenovo Support
Step 1. Configure the interconnect you are replacing outside of the stack environment.
The default credentials are:
• Username:
manager
• Password:
ThinkAgileCP
Step 2. On the replacement interconnect, perform the following steps in Cloud Controller:
a. Edit
/etc/tacp/tacp_switch_resource.sh
to populate the entries based on settings gathered
above (see Installation documents).
b. Replace
/etc/tacp/controller_uuid
with the value from the database.
c. Update
/usr/share/tacp/datastore.sqlite
using sqlite3 commands, with
<DHCP_RANGE_
START>
and
<DHCP_RANGE_END>
representing values from the database:
INSERT INTO property (name,value) VALUES ('DHCP_RANGE_START', '<DHCP_RANGE_START>');
INSERT INTO property (name,value) VALUES ('DHCP_RANGE_END', '<DHCP_RANGE_END>');
Step 3. Redo any per customer custom configuration from the install journal.
Step 4. On the primary interconnect switch:
a. Edit
/etc/tacp/tacp-network-controller.conf
and set
peerServiceTag
to the replacement
interconnect’s serial number.
b. Restart the Network Controller Services using the following command: > > ssu ud do o sseerrvviiccee ttaaccp p--
n neettw wo orrkk--cco on nttrro olllleerr rreessttaarrtt
Step 5. Replace the failed interconnect switch with the new interconnect, including the cabling. See
