Adding new storage enclosures to an existing cluster

  1. Ensure that the storage enclosure being added is supported by reading through the Dell Storage with Microsoft Storage Spaces Support Matrix .
  2. Ensure that adding the new storage enclosure results in a valid and supported configuration by reading through the supported configurations in the Dell Storage with Microsoft Storage Spaces Support Matrix .
  3. Install the storage enclosure into the rack following the guidelines in the storage enclosure owner’s manual.
  4. Read through the Dell Storage with Microsoft Storage Spaces Cabling Guide to determine the quantity of new SAS host bus adapters and SAS cables required.
  5. Install the new SAS host bus adapters in the existing cluster nodes one node at a time. Pause cluster services on the node and take the node offline. Ensure to reassign the current vote to the other server in Failover Cluster Manager, prior to turning off the node. After installing the SAS host bus adapters, turn on the node and resume cluster services, by unpausing and reassigning the current vote back to the initial server node in Failover Cluster Manager.
  6. Ensure that all roles and cluster resources have been distributed back to the original owning nodes.
  7. Ensure that all the new and existing SAS host bus adapters are cabled according to the Dell Storage with Microsoft Storage Spaces Cabling Guide .
    • NOTE: If this step is performed as an online expansion, when updating the existing cabling and to ensure data path availability to existing enclosures, always ensure there is at least one SAS path available to the existing storage enclosures.
  8. Ensure that all SAS host bus adapters have been detected in each server in the cluster.
  9. Turn on the newly added storage enclosure.
  10. Ensure that the new storage enclosure and all of its physical disks are detected by all servers in the cluster.
  11. Update the SAS host bus adapter firmware and drivers and physical disk firmware to the latest supported versions listed in the Dell Storage with Microsoft Storage Spaces Support Matrix .
  12. Add the new physical disks to a storage pool following the best practices in the Dell Storage with Microsoft Storage Spaces Cabling Guide .
  13. By using the newly added capacity, either resize an existing virtual disk by running the command Resize-VirtualDisk for virtual disks without storage tiers or Resize-StorageTier for virtual disks with storage tiers; or create new virtual disks.
  14. If an existing virtual disk is resized, the volume on the disk must be resized by running the command Resize-Partition.
