Oracle VM

Deployment in Oracle VM environment

The Oracle VM environment requires you to create storage used for VM export. The export storage repository should also be accessible by vProtect Node in its staging directory. This implies that storage space doesn't have to be exported by vProtect Node - it can be mounted from an external source. The only requirement is to have it visible from both OVM hosts and Node itself. Keep in mind that ownership of the files on the share should allow both vProtect and OVM to read and write files.

Backup Process

  • crash-consistent snapshot is taken by OVM during hot-clone of the VM
  • data + metadata exported by the manager to the vProtect staging space (visible as the export Storage Repository in OVM)
  • full backup only is supported
  • OVM exports are limited to 1 task per Storage Repository being used by VM (this is the _**_limitation of OVM)
  • restore is done to the export Storage Repository, the administrator needs to clone the VM using manager UI
Note:
  • If the virtual machines are running on NFS storage, you must shut down the Oracle virtual machines to perform the backup
  • Make sure the NFS share have the vProtect user UID and GID
  • The directory under / vprotect_data needs to be the same name as the OVS server pool name
  • Oracle VM needs to disable services (nfslock , rpcbind)
  • Restore of VM is multi-step
    • Restore to the staging space on vNode
    • Move VM from the staging space to the Oracle protection repository
    • Migrate the VM into the Oracle server pool
Oracle VM environments require storage repositories to be defined for each server pool and must be mounted on vProtect node.
  1. 1.
    Create a repository from NFS share on vProtect node
    • One server pool should have a separate subdirectory in the export path i.e. /vprotect_data/pool01, /vprotect_data/pool2 - each subdirectory is a separate NFS share
    • The export (staging) path in the above-mentioned scenario is still /vprotect_data, while pool01 and pool02 are server pool names
    • Specify mapping between server pool names and storage repository names in the hypervisor manager configuration
    • Note that the export must be set to use the UID and GID of the vprotect user
    • Example export configuration in /etc/exports to the selected hypervisor in the RHV cluster:
      /vprotect_data/pool01 10.50.1.101(fsid=6,rw,sync,insecure,
      all_squash,anonuid=993,anongid=990)
      /vprotect_data/pool02 10.50.1.102(fsid=7,rw,sync,insecure,
      all_squash,anonuid=993,anongid=990)
      where anonuid=993 and anongid=990 should have the correct UID and GID returned by command:
      [[email protected] ~]# id vprotect
      uid=993(vprotect) gid=990(vprotect) groups=990(vprotect)
  2. 2.
    Both import and export operations will be done using these NFS shares – restore will be done directly to this storage domain, so you can easily import the backup into the Oracle VM environment
    • Backups must be restored to the export path (the node automatically changes the names to the original paths that are recognized by the OVM manager.

Example - How to configure OVM protection with PowerProtect DD

  • Create a DDBoost device
  • Create NFS share
  • Mount the DDBoost device on vProtect Node
  • Create symbolic links for the OVM Pool name (MyServerPool) to BoostFS mount point command, for example: ln -s /vprotect_data /MyServerPool
  • Create a Storage Server for DD NFS Share
  • Create a Repository using DD
  • Add the OVM Hypervisor Manager to vProtect Note: You can get the "Storage Repository ID" from the "OVM repositories" menu shown in the previous step
  • An example of how "OVM" objects should look after resource synchronization
  • Example of Backup Destination Configuration
That's it, now you should be able to back up your environment
