     • FlexClone or lun clone create to provision
       read/write volumes from SnapShots.
     • Map the new LUNs to ESX host(s) igroup.
     • VirtualCenter – rescan each HBA / iSCSI initiator
       on ESX host(s) to discover the new LUN.
     • Recovery VMDK files or discrete files in VM.

     • Full Volume Recovery (all VMs): Power off VMs
       and leverage SnapRestore to revert entire Volume.

    • Individual VM Recovery: Power off VM and
      leverage SnapRestore to revert VMDK files.

    • Recover discrete files in VM.

NetApp and VMware Considerations
  1. Prepare to recover VirtualCenter Server at DR Site.

  2. Set LVM.DisallowSnapshotLun option to 0 to allow
     SnapShots to be seen as valid VMFS DataStores.

  3. Consider VM Settings that can impact inter-site
     recovery:

     • UUID: modify .vmx file to set uuid.action=”keep”
       parameter to prevent recreation of the UUID.

     • VM MAC Addresses: Plan strategy for providing IP
       Addresses to VMs at the DR site.

     • Quiesce to commit changes in flight.
     • Break SnapMirror relationship.
     • On-line the volume(s) in DR site.

  3. VirtualCenter – rescan the data paths to discover and
     mount the DataStores on each ESX host.

  4. Add all virtual machines to the inventory

  5. Power on VMs.

                  Replication / What if scenario ?

•   Q. If a Replication update does not complete and a new update is
    scheduled, is the new update just skipped or does it start right after the
    previous update completes?
•   A. If a Replication update is still in progress when the next update is
    scheduled to begin, it marks the relationship to run again and will start the
    new update at the top of the next minute.
    For example, if you have an hourly update and the 1 a.m. transfer goes to
    2:30 a.m., the 2 a.m. scheduled update marks the update as desired and
    begins the new update at 2:31 a.m. If that update finishes before 3 a.m.,
    updates will be back on schedule. If that update finishes at 3:05 a.m., the
    next update will begin at 3:06 a.m.
    As another example, if you have an hourly update a 1 a.m. that finishes at
    3:30 a.m., the replication engine marks the relationship for running again at 2
    a.m. and 3 a.m. At 3:31 a.m., the replication engine begins the next update.
    If that update finishes before 4 a.m., the next transfer will begin at 4 a.m.
    Note: If a scheduled update is reached when a previous update is running,
    the replication engine marks, not queues, the relationship to do another
    update. Only one mark is seen, regardless of how many times the
    relationship is marked to go again.

               Replication / What if scenario ?

• Q. Under what conditions can or cannot a replication transfer be
  restarted from a checkpoint and what is required to ensure that an
  interrupted transfer with a checkpoint can restart from the
  checkpoint?
• A. The replication engine saves restart checkpoints during a transfer
  so that in case of transient errors like temporary network outages, it
  can resume the transfer rather than resend the data it has already
  transferred. Replication transfers take a new checkpoint every five
  minutes.
  The replication engine retries an interrupted transfer from the
  checkpoint until the next update transfer is scheduled. The next time
  a transfer is scheduled to begin, abandon the interrupted transfer
  and start the update from the last base snapshot.

•VMWARE Certified        - StoreVault and VMware have partnered together to provide small
and medium-sized businesses with server virtualization solutions to better manage storage and
server resources

•Oracle Certified - The StoreVault S500 is now qualified with Oracle 10g Standard Edition
for three configurations - NFS on Linux, ASM on Linux iSCSI, and ASM on Windows iSCSI.

•Exchange and SQL Certified - A fully-loaded StoreVault S500 system provides 12
disk drives with a best practice recommendation that 9 be used for data (as well as 2 for parity,
leaving 1 hot spare). Microsoft’s standard benchmarking tool for Exchange, MMB-3, indicates
that over 700 mailboxes can be comfortably supported on one StoreVault S500.
