Establish connectivity to the peer node via SSH
Before beginning the replacement procedure, ensure that your connection to the peer node is working correctly.
About this task
CAUTION: Before you begin this procedure, establish a connection to the healthy node to run service commands
via SSH. You need to run the svc_repair command immediately after re-inserting the node to allow the system
to reimage the new internal M.2 boot module from the surviving node. To prevent time out issues with the
svc_repair command, it is important to first resolve any problems with the connection.
Steps
1. Launch an SSH client, and connect to the appliance using the peer node IP address.
2. Enter the username and password for the service account to log in.
Power down the node
Power down the node as described in Power control procedures.
Remove the node
This procedure describes how to remove a node from the chassis. There are two nodes. The top node is considered to be
upside-down and mirrors the bottom node. The procedure for removing the top node and the bottom node is the same.
Prerequisites
If the I/O modules and network cables are not already labeled, label them clearly for reconnecting later.
About this task
WARNING:
Do not remove the node within five minutes of system power down to ensure that the system has
had time to complete caching.
CAUTION: Do not remove a node while the "Unsafe to remove" LED is lit. The location of this LED is described
in Embedded module LEDs. If the LED is lit, the peer node has been powered down or is offline and this node
should not be removed.
CAUTION: Because nodes include cooling fans, they should be removed for as short a time as possible. Do not
remove nodes from a live system unless replacement parts are available.
Steps
1. Rotate the power cable retention bail to the left (right for top power supply). Disconnect the power cable from the power
supply.
