= Introduction =

These are the required steps to use NIM in your disaster recovery procedure.

= Create Mksysb Image =

* Check network and DNS requirements for your host / network
  * [[nimnetwork]]
  * Host needs A and PTR records
* Check storage NIM server
  * The NIM server needs at least the amount of space of the rootvg of the host
* Create nim client
  * [[aixnimclientadd]]
* Create the image
  * [[aixnim#create_a_mksysb_image]]

= Restore Mksysb Image =

* Restore the image
  * [[aixnim#restore_a_mksysb_image]]
  * [[aixniminstall]]

These are the steps for a test, so you create an entire new client for testing purposes. In this case we restore to a LPAR in an IVM. Before starting, determine a host name and IP address what can be used.

* Create required boot lun
  * [[netappstorage]]
* Detect lun inside VIOS/IVM
  * [[aixvios]]
* Create LPAR
  * [[aixivmlpar]]
* Create DNS records
  * Create A and PTR records
* Create NIM Client
  * [[aixnimclientadd]]
* Restore the image
  * [[aixnim#restore_a_mksysb_image]]
  * [[aixniminstall]]
