EMC2 VNXe3100 User manual

This document describes how to upgrade the input/output (I/O) modules in a VNXe3100
or VNXe3150 dual-SP disk processor enclosure (DPE) to a different type of module.
Upgrading the I/O modules requires that both SPs have 8 GB of memory.
IMPORTANT
Your VNXe system must be running VNXe Operating System Environment 2.3 or later for
you to upgrade its I/O modules.
When you upgrade I/O modules, you must upgrade the I/O module in each SP.
Before you start
Before you begin the procedure:
◆Make sure you have the correct I/O modules for the upgrade. The VNXe3100 Hardware
Information Guide
and the VNX3150 Hardware Information Guide on the VNXe
Support site (emc.com/vnxesupport) contains a list of supported I/O modules.
◆Refer to your EMC® VNXe™ online help (Servicing your system > Adding or replacing
faulted hardware components > Add a new hardware component) for instructions on
how to identify I/O modules and handle hardware components.

Task 2: Preparing the storage processor (SP) for service
IMPORTANT
To protect your VNXe system from accidental data loss while you upgrade an I/O module in
an SP, you must prepare the SP for service before you upgrade any of its I/O modules. You
prepare the SP for service by putting it in Service mode. Both SPs must not be in Service
mode at the same time.
1. Open Unisphere™ and select Settings, then Service System.
2. Log in with your service password.
3. In the System Components column, select the storage processor (SP A or SP B).
4. Under Service Actions, select Enter Service Mode, then Execute service action.
5. In the Service Confirmation dialog box click OK.
Putting an SP into Service mode takes about 10 minutes. The storage processor fault
LED will flash alternating amber and blue while the SP remains in Service mode and is
receiving active power.
6. Wait until the SP fault LED is flashing alternating amber and blue before continuing to
the next task.

Task 3: Remove the SP assembly
The I/O module resides on the SP printed circuit board (CPU board). To upgrade an I/O
module, you must remove the SP assembly from the chassis, and then remove its cover to
gain access to processor board components.
Follow these steps to remove the SP assembly:

DO NOT REMOVE an SP assembly while the “Unsafe to remove SP” LED is on. The
light indicates that you may interrupt a vital system or data-caching process.
1. Disconnect the network and all other cables from the back of the assembly that will
include the new I/O module.
Do not remove any cables from the other SP assembly.
Mark the cables with the port numbers from which you removed them.

The SP assembly comes completely out of the chassis. In addition to holding the
latches, be prepared to support the SP assembly to avoid dropping it.
2. Locate the left and right latches.

Troubleshooting
EMC VNXe3100/VNXe3150 — Upgrading Input/Output Modules 13
Troubleshooting
If any network settings on the third and fourth ports of the old I/O modules were not
removed prior to the I/O module upgrade, these settings are visible in Unisphere. Also, in
the Shared Folder Server Settings and/or iSCSI Server Settings dialog box, the IP address
is Not configured for these ports. These network settings cannot be reused or
removed after the upgrade. To fix this situation, follow this procedure:
1. Log into Unisphere™ and select Settings, then Service System.
2. Log in with your service password.
3. In the System Components column, select Storage System.
4. Under Service Actions, select Enable SSH, then Execute service action.

6. Download an SSH client, such as PuTTY, to a computer that has network access to the
system.
You may need to install the SSH client before you can launch it.
7. Launch the SSH client.
8. In the SSH client, use the management IP address to connect to the VNXe system.
For example, in PuTTY, type the management IP for the destination.
9. Log in as the Service user, then type the password for the Service account to log in to
the system.
10. Use the svc_change_config command with the --cleanup_network option to remove
the network settings on any non-existent ports.
For example:
service@vnxe126 spa:~> svc_change_config --cleanup_network
Found the following network interfaces on non-existent ports.
Found invalid entry: linux_dev=eth13 protocol=IP device=fsn13
local=10.6.6.6 netmask=255.255.255.0 broadcast=10.6.6.6 mtu=1500
vlan=0
Found invalid entry: linux_dev=eth12 protocol=IP device=fsn12
local=10.6.8.127 netmask=255.255.255.0 broadcast=10.6.6.6 mtu=1500
vlan=0
Removing these interfaces requires restarting the management
services on the SP.
