Answer

Powering down nodes
  • Before moving, dismount all clients, disable Network File System (NFS) and terminate Common Internet File System protocol (CIFS).
  • Then take volume snapshot - a consistent file system copy.
  • Reboot the node before moving it and ensure that a reboot Autosupport was sent. This will help in troubleshooting boot time problems at the destination.
  • Halt the node.
  • Allow power down to reach ambient temperature.
  • Remove the power from the node.
  • Then power down the shelves.
  • Power up and down in phases: Power off first move first and power off last move last.
Packing, moving and unpacking
  • Are the nodes in cabinets or racks?
    If racks do not stack any shelves on top of each other, it will compress the shelf/drive canister.
  • All equipment should be moved on shock absorbent material, i.e. no head or nodes moved on a wooden dolly, put foam underneath.
  • Has the new datacenter/location been verified for RH, power and HVAC?
  • The RC files will have to be changed to reflect the new sub-net if there is any change.
  • Have a minimum of 3 people available for the movement and unpacking of the nodes.
  • In case carts are being used for movement of nodes please ensure that the carts have rubber wheels.
  • It is recommended that the crates that were used for shipping the nodes to the site be used for repacking of the nodes for movement.
  • Ensure sufficient buffer packing is available inside the crate after packing the node into it.
  • Thermocol of any kind should not be used in the vicinity of the nodes.
  • Screws for the node head and disk shelves should be checked before packing the node cabinets into crates. This is to check for loose parts that could move during the shifting.
  • It is recommended to use tall power lifts to move the packed nodes across levels.
Power on at new site
  • Ensure the node and shelves are connected as it was before
  • Check to make sure that the screws and cables are tight
  • Power on the shelves first
  • Power on the node
  • The node will hang trying to resolve DNS names if DNS is not corrected in advance to show new IP ranges if there is a change.
  • Setup a separate verification of name/IP resolution in the new site before the move.
  • Before moving the node to a new network, ensure that:
    • Clients can ping each other (client <-> client ping)
    • Name resolve is working fine with nslookup, tracert and
    • Gateway is working fine by pinging the client from outside (client<-outside world ping).
  • Allow power up to reach ambient temperature
  • Check everything is up and running before moving into production.
