From 1320556
My suggestion is use the comment#4 to create the documentation and the
comment#6 is about showing how the kickstart file was created but it's not
needed as you already documented here:

http://file.tlv.redhat.com/~eheftman/bz1369874/html-single/#Automating_RHVH_Deployment


"""

Users that contain local storage environment are able to migrate from RHEV
Hypervisor 3.6 to RHV Hypervisor 4.

Tip: In case advanced installation (kickstart) is used to redeploy the machine
with RHV 4, keep in mind to not overwrite your data, example:

  To autoinstall and avoid erase any file in /dev/sdb, use the following in the
kickstart:

    "clearpart --all --drives=sda"


* After RHV Hypervisor is installed (*Keep in mind to leave your local storage
data intact)

Create directory /data to recover your previous environment
#2 mkdir /data

Mount the previous local storage in /data
#3 mount /dev/sdX1 /data

Set permissions to /data
#4 chown -R 36:36 /data
   chmod -R 0755 /data


To automount the partition in /data (in case the server requires a reboot), use
the following example:

Example:
   # blkid | grep -i sdX1
   /dev/sdX1: UUID="a81a6879-3764-48d0-8b21-2898c318ef7c" TYPE="ext4"

   # vi /etc/fstab
   UUID="a81a6879-3764-48d0-8b21-2898c318ef7c" /data     ext4          defaults
    0       0


Importing the local storage into RHVM:

#5 Create DataCenter for Local Storage
#6 Create Cluster for Local Storage
#7 On Storage Tab, use a different dir than /data to create your initial local
storage for later import your previous environment, example: /localfs

   On RHV Hypervisor:
     mkdir -p /localfs
     chown 36:36 /localfs
     chmod -R 0755 /localfs

   On RHV-M add the local storage in the Storage Tab:
   Name: localfs
   Path: /localfs

#9 After localfs storage is UP, let's import the existing local storage:

   Storage tab, Import Domain

   Name: Data
   Storage type: Local on Host
   Path: /data


Confirm the following:
"""
  Storage Domain(s) are already attached to a Data Center. Approving this
operation might cause data corruption if both Data Centers are active.
"""

To active your data storage:
  In the datacenter tab, go to storage sub-tab and active the data storage
domain just imported (Data and local-fs should be UP)

To import the virtual machines:
  In the Storage Tab, select the data (imported domain) and go to sub-tab 'Vm
Import' and select the vm and click import
 (It should import the vm and disk)

Finally, after virtual machines and disks were imported and tested, in the
datacenter tab you can put the localfs storage in maintenance (as it won't be
used)
