Migrating the Cisco Nexus 1000V VSMs
This document describes how to migrate the Cisco Nexus 1000V VSMs in high-availability (HA) pair from Cisco Nexus 1010 Virtual Services Appliance (Cisco Nexus 1010 VSA) or Cisco Nexus 1100 Cloud Services Platform (Cisco Nexus 1100 CSP) to Cisco Cloud Services Platform 2100 (Cisco CSP 2100) while keeping one VSM active at all times.
Prerequisites
Following are the prerequisites for migrating the Cisco Nexus 1000V VSMs while keeping one VSM active:
Cisco Nexus 1010 VSA or Cisco Nexus 1100 CSP must have Release 4.2(1)SP1(4) or later.
Layer 2 connectivity must exist between the Cisco Nexus 1010 VSA or Cisco Nexus 1100 CSP and the Cisco CSP 2100.
Layer 2 or Layer 3 connectivity (depending upon the SVS connection mode) must exist between the Cisco CSP 2100 and the VEMs.
Migrating the Primary VSM
Exporting the Primary VSM
Before You BeginProcedure
Log in to the Cisco Nexus 1010 VSA or Cisco Nexus 1110 CSP CLI in EXEC mode.
Make sure all prerequisites specified in Prerequisites are met.
Importing the Primary VSM
This section describes how to import the primary VSM image file to Cisco CSP 2100 by using the web interface. You can also use the Cisco CSP 2100 commands and REST APIs to import the primary VSM.ProcedureTo import the primary VSM through web interface, do the following:
Verifying High Availability After Importing the Primary VSM
A few minutes after the primary VSM on Cisco CSP 2100 is powered on, the console of the secondary VSM displays messages of the system entering the HA mode as shown in the following example. If these messages are not displayed, verify the layer 2 connectivity between the vnic1 interface on both primary and secondary VSMs.
