This document describes how to use the migration tool to migrate from vCenter hosts to vCenter Cluster as hosts. Please contact Abiquo Support to obtain this tool.

Procedure

Prepare your environment

  1. The vCenter Cluster plugin requires a configured dvSwitch on each cluster, so make sure that the distributed virtual switch is available on each cluster beforehand.

  2. Double check your environment's disk usage to make sure that no partitions are full or close to.

  3. Check the licenses installed in your environment:

    1. Your license has to be the 'vCenter Cluster' plugin enabled.

    2. Your license has to allow the use of at least as many cores as your cluster currently have.

  4. Check that there are no database inconsistencies. From the CLI for your database, run the following queries, there should be no results:

    1. Check for VMs that are not allocated but have a datastore assigned:

      1. SELECT vm.name, dm.idManagement, dm.idDatastore, vm.idHypervisor FROM kinton.disk_management dm, kinton.rasd_management rm, kinton.virtualmachine vm WHERE dm.idManagement = rm.idManagement AND rm.idVM = vm.idVM AND vm.state = 'NOT_ALLOCATED' AND dm.idDatastore IS NOT NULL;

    2. Check for VMs that are not allocated but have a hypervisor assigned:

      1. SELECT vm.name, dm.idManagement, dm.idDatastore, vm.idHypervisor FROM kinton.disk_management dm, kinton.rasd_management rm, kinton.virtualmachine vm WHERE dm.idManagement = rm.idManagement AND rm.idVM = vm.idVM AND vm.state = 'NOT_ALLOCATED' AND vm.idHypervisor IS NOT NULL;

    3. Check for which disks are stored in which datastores that are referencing non-existant virtual machines.

      1. SELECT dm.idManagement, dm.idDatastore, dm.type, dm.label, SUBSTRING(pm.name,1,7) as pmName FROM kinton.disk_management AS dm INNER JOIN kinton.rasd_management AS rm INNER JOIN kinton.scheduled_resources AS sr INNER JOIN kinton.physicalmachine AS pm WHERE dm.idDatastore = sr.idDatastore AND sr.idPhysicalMachine = pm.idPhysicalMachine AND dm.idManagement = rm.idManagement AND rm.idVM IS NULL;

    4. Check for virtual machines which disks are stored in the datastores that will be deleted along their physical machine associated:

      1. SELECT vm.name, h.idPhysicalMachine, dm.idDatastore FROM kinton.disk_management AS dm, kinton.rasd_management AS rm, kinton.virtualmachine AS vm, kinton.hypervisor AS h WHERE rm.idManagement = dm.idManagement

      = rm.idManagement AND rm.idVM = vm.idVM AND vm.state = 'NOT_ALLOCATED' AND dm.idDatastore IS NOT NULL;SELECT vm.name,

      1. AND rm.idVM = vm.idVM AND vm.idHypervisor = h.id AND dm.idDatastore IN (SELECT sr.idDatastore FROM kinton.physicalmachine AS pm, kinton.scheduled_resources AS sr WHERE pm.idPhysicalMachine != h.idPhysicalMachine AND sr.idPhysicalMachine = pm.idPhysicalMachine);

  5. Check that there are no additional database inconsistencies. From the CLI for your database, run the following queries, there should be no NULL values in the idVM column:

    1. Check for disk management entries referencing datastores but which are not assigned to a virtual machine:

      1. SELECT dm.idManagement, dm.idDatastore,

      vm

      1. rm.

      idHypervisor

      1. idVM FROM kinton.disk_management AS dm

      ,

      1. INNER JOIN kinton.rasd_management AS rm

      , kinton.virtualmachine vm

      1. WHERE dm.idManagement = rm.idManagement AND

      rm.idVM = vm.idVM AND vm.state = 'NOT_ALLOCATED' AND vm.idHypervisor

      1. idVM IS NULL AND idDatastore IS NOT NULL;

Step by step migration

To upgrade your currently added vCenter hypervisors to vCenter cluster, then the process is as follows:

  1. Familiarize yourself with the migration tool. Please execute it without parameters to see the available options:


    1. Code Block
      languagebash
      # java -jar vcenter-cluster-upgrade-0.3.jar
 -apipass (--api-password) VAL                             : abiquo API login password
 -apiuser (--api-user) VAL                                 : abiquo API login user
 -dcid (--datacenter-id) VAL                               : id of the datacenter to migrate
 -oauthAccessToken (--oauth-access-token) VAL              : abiquo API oauth access token
 -oauthAccessTokenSecret (--oauth-access-token-secret) VAL : abiquo API oauth access token secret
 -oauthConsumerKey (--oauth-consumer-key) VAL              : abiquo API oauth consumer key
 -oauthConsumerSecret (--oauth-consumer-secret) VAL        : abiquo API oauth consumer secret
 -op (--option) VAL                                        : operation to perform [check, apply]
 -passfile (--password-file) VAL                           : file with passwords to vcenter
 -url (--api-url) VAL                                      : abiquo API base url


  2. Get the following information from your environment:

    1. API_ENDPOINT: FQDN (and maybe the port) to the Abiquo API.

      • For example: https://dev.myabiquo.com/api

    2. , API_USER: an enabled administrator account from the Abiquo environment where the migration will take place.

      1. For example: admin

    3. API_PASS: the password for the previous user account.

    4. DC_ID: Unique DB ID for the Abiquo datacenter you are about to migrate. One way to obtain that information is by querying the Abiquo database directly and get the appropriate integer from the idDataCenter column:

      Code Block
      SELECT idDataCenter, situation FROM kinton.datacenter;


  3. Create a temporary file with the appropriate vCenter credentials; this is the passfile parameter for the migration tool. This file has to follow the following guidelines:

    1. it must have 3 columns, separated by a single space.

    2. the first column must be the vCenter IP.

    3. the second and third columns must contain the vCenter credentials for the cloud admin.

  4. An example for this file is as follows:


    1. Code Block
      languagetext
      VCENTER_IP1 VCENTER_USER1 VCENTER_PASS1
VCENTER_IP2 VCENTER_USER2 VCENTER_PASS2


  5. Check that the tool has network access to both the Abiquo API and the appropriate vCenter.

  6. Execute the tool in dry run mode and check for no errors, replacing API_ENDPOINT, API_USER, API_PASS, DC_ID and PASS_FILE with the appropriate values from the previous steps:


    1. Code Block
      languagebash
      # java -jar vcenter-cluster-upgrade-0.3.jar  -op check -url 'API_ENDPOINT' -apiuser 'API_USER' -apipass 'API_PASS' -dcid 'DC_ID' -passfile 'PASS_FILE'

  7. Execute the tool again replacing the op parameter from check to apply, replacing API_ENDPOINT, API_USER, API_PASS, DC_ID and PASS_FILE with the appropriate values from the previous steps:

Known errors

  • Error 409. MACHINE-21 - At least one network interface must have a network service type assigned: your cluster has to have configured a distributed virtual switch in Abiquo before starting the migration, as stated before.

  • Error 500 Internal Server Error - Unexpected exception: please check the api.log log file.

Important considerations

  • Resources in infrastructure will be changed from VMX_04 to VCENTER_CLUSTER.

  • The VDC hypervisor type will change from VMX_04 to VCENTER_CLUSTER (registered on the Events tab).

  • The migration process will automatically retrieve all VMs from all hosts.

  • From Abiquo 4.5.1 onwards, you do not need to recapture VMs. After you complete the migration check your VMs

  • In Abiquo 4.7.6 and from 5.1 onwards, the platform can proceed with the migration even when there are protected VMs.

If you are using the Networker plugin...
