Server replacement procedures
The replacement of the server as part of a field service process can take several forms
depending on how the system was originally deployed. The typical field deployment
scenarios documented for service replacement include:
■
Two-node cluster using an external SMU for management-replacing only one node
■
Two-node cluster using an external SMU for management-replacing both nodes
Important: This document does not treat migration scenarios between
different configurations at the time of replacement.
Replacement procedure overview
This section provides information on the requirements and considerations for replacing
nodes.
Server replacement requirements
Consider the following server replacement requirements:
■
Much of the process required for a server replacement is the same as what is covered
in installation and configuration training.
■
Determine which replacement scenario is being encountered. The replacement
process is different for each scenario.
Note: Replacement servers are shipped without an embedded system
management unit (SMU), so you must install the SMU before you can connect
to a stand-alone server.
You can use a keyboard, video, and mouse (KVM) device or a serial cable to connect to
the serial port. Bring these with you just in case they are needed when the unit arrives. If
you connect to the serial port, use the following SSH client settings:
■
115,200 b/s
■
8 data bits
■
1 stop bit
■
No parity
■
No flow control
■
VT100 emulation
