Replacing the chassis

To replace the chassis, you must move the power supplies, hard drives, and controller module or modules
from the impaired chassis to the new chassis, and swap out the impaired chassis from the equipment rack or
system cabinet with the new chassis of the same model as the impaired chassis.
Before you begin
All other components in the system must be functioning properly; if not, you must contact technical support.
About this task
• You can use this procedure with all versions of ETERNUS AX/HX Series supported by your system.
• This procedure is written with the assumption that you are moving all drives and controller module or
modules to the new chassis, and that the chassis is a new component from Fujitsu.
• This procedure is disruptive. For a two-node cluster, you will have a complete service outage and a partial
outage in a multi-node cluster.

Shutting down the controllers when replacing a chassis

You must shut down the controllers before replacing the chassis.

Shutting down the node

You must shut down the node or nodes in the chassis prior to moving them to the new chassis.
Before you begin
• If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a
healthy node shows false for eligibility and health, you must correct the issue before shutting down the
impaired node.
1. If your system has two controller modules, disable the HA pair.
If your system is running clustered ETERNUS AX/
HX Series with...
Two nodes in the cluster
More than two nodes in the cluster
2. Halt the node, pressing y when you are prompted to confirm the halt: system node halt -node
The confirmation message looks like the following:
Warning: Rebooting or halting node
"node_name" in an HA-enabled cluster may result in client disruption or
data access
failure. To ensure continuity of service, use the "storage
failover takeover" command. Are you sure you want to halt node
"node_name"? {y|n}:
Attention: You must perform a clean system shutdown before replacing the chassis to avoid
losing unwritten data in the nonvolatile memory (NVMEM). If the NVMEM LED is flashing, there is
content in the NVMEM that has not been saved to disk. You need to reboot the node and start from
cluster ha modify -configured false
storage failover modify -node node0
-enabled false
storage failover modify -node node0
-enabled false
