If the chassis or backplane is defective, the chassis must be replaced.
Read, understand and observe all the warnings and cautions given in Safety and Handling Instructions, Rack Warnings and Cautions and Ice Lake CBox (DELL) Warnings and Cautions before performing the procedures given below.
Caution
The Ice Lake CBox (DELL) must be powered on throughout this procedure. Powering down Ice Lake CBox (DELL) will cause data unavailability, especially on clusters with one CBox.
Caution
Install the new chassis first, then deactivate and move one CNode at a time from the old to the new chassis. Activate the CNode in the new chassis and monitor the CNode for correct operation. Repeat this for all the Cnodes.
Caution
When deactivating CNodes, make sure to maintain the following ratios to maintain cluster viability and data availability:
-
For larger clusters, at least 2 fully operational CNodes must be available for every 20 operational DNodes.
-
For smaller clusters, at least 1 fully operational CNode must be available.
Before deactivating a CNode, confirm that the vippools using this CNode contain at least one another CNode which is not running VMS
-
Deactivate one CNode in the defective CBox. For instructions on deactivating a CNode, see Activate or Deactivate a CNode.
-
Power down the CNode and disconnect the peripheral connections. Label the cables before removal to make sure they are re-inserted in the correct ports of the new chassis. Do not disconnect the power cables to the Ice Lake CBox (DELL).
-
Remove the CNode and install it into the new chassis, see Replacing a CNode.
-
Power the CNode on.
-
Connect the peripheral connections to the Ice Lake CBox (DELL).
-
Activate the CNode. See Activate or Deactivate a CNode.
-
Repeat these steps until all the CNodes have been moved to the new chassis.
