Installation prerequisites (SSR task)
Customers must fill the “Installation worksheet” on page 45 for the SSR to start installation. This
process must be done by using the Technical Delivery Assessment (TDA) process. The installation
worksheet describes the IP addresses that the SSR sets on each node.
The SSR might need the following things for the ESS 5000 installation:
• Ethernet cable
• USB-C (or USBA) to Ethernet dongle (This connector is required if your laptop does not have an Ethernet
port.)
• Serial cable for POWER9
™
servers
• USB-C (or USBA) to Serial dongle
If available, power on the high-speed switch(es) and connect the Ethernet or InfiniBand cables to the
adapters that are installed within the POWER9 servers. This step must be done before the customer can
deploy the cluster but is not required for code 20. The low-speed Ethernet cables must be run to the
proper locations on both switch and server sides before code 20 can begin (If the system came racked
with the management switch this step is done in manufacturing).
The goal is to install the hardware and perform a full code 20. After performing the code 20, SSR should
provide the following information to the customer or LBS. Fill this information in the “Installation
worksheet” on page 45.

• Installation notes
Installation steps (SSR task)
This section is a high-level overview of the tasks that an IBM service support representative (SSR)
performs to complete code 20.
SSR objectives
1. Log in by using the SSR ID (esserv1) and run the specified essutils command options on each
server in the following order:
a. One or more ESS 5000 building blocks
b. Two or more ESS 5000 protocol nodes
c. An ESS 5000 management server (EMS)
Note: This is the order to be followed for a new customer. If you are adding a building block or
protocol node(s) the sequence is adjusted slightly.
2. Set the root password to ibmesscluster from within essutils . This password is set to expire from
manufacturing but must be set to run the essutils SSR task options.
3. Perform all specified hardware validation options. You will run a subset of the commands for the EMS
and protocol nodes, if available. The I/O servers have more checks because they are connected via
SAS to the storage enclosures.
4. Set HMC1 and OS management IP address. On the EMS, you also need to set the FSP interface on the
OS. For more information about the interface and the IP address, see “Installation worksheet” on page
45.
5. Perform ping test from the EMS to the I/O servers and the protocol nodes. This ping test is performed
to check whether connections to the management (C11-T1) and FSP interfaces (HMC1) are working
properly.
6. Document issues on the customer worksheet for use by the customer or LBS.
