Dell EMC VNXe3100 User manual

This document describes how to add a second storage processor (SP) to a VNXe3100 or
VNXe3150 disk processor enclosure (DPE).
Before you start
Before you begin the upgrade procedure :
◆Make sure you have a current backup of your system data before you begin this (or any
other) upgrade procedure.
◆Make sure your VNXe system is running Maintenance Release 1 Service Pack 1
(version 2.1.1) or later. See the Unisphere online help for information about updating
your system software.
◆Make sure you have a new storage processor available to replace the cache protection
module, four 4 GB memory modules, and any I/O module required to match the
current SP. You also need appropriate network and SAS cabling to duplicate the
connections to SP A.
◆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 handle hardware components. Take particular care to review the instructions
on avoiding electrostatic discharge (ESD).
IMPORTANT
Since the procedure to upgrade from a single SP to two SPs involves reboots and the
temporary quiescence of the sole processor, your system will not process or make
available any data until the procedure is finished. Plan you upgrade accordingly.

The SP fault LED will flash alternating amber and blue while the SP remains in Service
mode and is receiving active power.
Task 2: Remove the cache protection module
To replace a cache protection module with a storage processor, you must completely
power down your entire system, including any attached disk-array enclosures (DAEs).

DO NOT REMOVE a cache protection module while the “Unsafe to remove” LED is
on. The light indicates that you may interrupt a vital system or data-caching
process.
Wait until both “Unsafe to Remove” LEDs are off, then perform the following steps:
1. On the DPE and
each DAE attached to the VNXe3100 or VNXe3150:
a. Release the cable retention bail and unplug the power cord from each power
cooling/module.
b. Mark the cords “A” or “B” for the power/cooling modules from which you removed
them.

Tasks to add an SP
Task 9: Connect SP B to the hosts and expanded storage
Connect the new storage processor B to your management LAN, system hosts, and to any
DAEs in your current system. Most configurations provide high availability by mirroring the
storage processor “A” connections.
If SP A supports a DAE, connect a SAS cable from SP B SAS port 0 to the link control card
(LCC) B input port (labeled with two circles). Connect additional SAS cables as required
from the first DAE output port (labeled with two diamonds) to the input port of the next
DAE in the configuration.
Note: Cabling information, installation, configuration, and planning guides are available
on the Support Site at emc.com/vnxesupport.
Task 10: Power up the system
Power up the DPE and any connected DAEs in your system:
1. Plug each power cord in your system back into its power/cooling module.
2. Make sure you secure the power cords with the retention bails at each connector.
The bails prevent the power cords from pulling out of the connections.
Each enclosure in your system will power up immediately upon connection to an active AC
power source. The system boots into Service mode in approximately 15 minutes. The
storage processor fault LEDs will flash alternating amber and blue while the SP remains in
Service mode and is receiving active power.
Note: If the fault LED remains solid amber on either of the SPs, refer to “Troubleshooting
Notes” on page 12.
Task 11: Validate the upgrade and reboot the system
Once you have installed the SP assemblies in the chassis, and the SPs have booted into
Service mode (as indicated by alternating amber/blue fault LEDs), run the service shell
script to validate the upgrade and boot the system into Normal mode.
1. Launch the SSH client.
2. 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.
3. Type the password for the Service account to log in to the system.
4. Type the name of the upgrade script: svc_change_config --commit.
It may take 15 to 20 minutes for the system to complete its reboot and return to
Normal mode. The fault LEDs on the storage processors will cease flashing and go
completely off in Normal mode.

Task 12: Diable SSH
Return your system to normal operating and security mode by disabling SSH:
1. If the Unisphere instance you used to enable SSH is still open, close it and then open
a new browser session.
2. Log in to Unisphere and select Settings, then Service System.
3. Log in with your service password.
4. In the System Components column, select Storage System.
5. Under Service Actions, select Disable SSH, then Execute service action.
6. In the confirmation dialog box, click OK to disable SSH.
Task 13: Verify the operation of the new SP assembly
Verify that the new SP B assembly and all its components are recognized by your system,
and operating correctly:
1. In Unisphere™, select System, then System Health.
2. Select the SP in the Component list or the graphical view:
• In the Component list, the new module should be marked with a status OK icon:
• In the graphical view, the module should be highlighted green.
The display highlights both storage processors in yellow until the boot process
completes.
3.
If you added an I/O module to either storage processor :
• If you just installed an I/O module in SP A, the display will remind you to install the
second module in SP B.
If you just installed a second I/O module, follow the onscreen instructions to
Commit I/O modules.
• After you install and commit both I/O modules, the Component list should mark
them with a status OK icon:
• In the graphical view, the I/O module is highlighted green.
If the system health monitor continues to show the processor, memory, or I/O module
as faulted after you commit the I/O modules, contact your service provider.

Troubleshooting Notes
Troubleshooting Notes
This section describes troubleshooting steps to follow in the event that you are having
problems. Note that these troubleshooting steps apply
before you validate the upgrade
and reboot the system to normal mode with the service script svc_change_config --commit
(see Task 8 “Validate the upgrade and reboot the system” on page 10); after that time,
please contact your service provider directly for assistance with your dual storage
processor system.
Problem: Running svc_change_config in normal mode, the following message is
displayed:
The upgrade cannot proceed. Please run the system health check
from the management application to determine the problem.
Solution: The service script detected a problem that prevents the upgrade. Running the
system health check from the management application is the best approach to diagnose
the problem.
Problem: After inserting an SP and restoring power, the SP does not reach service mode
(indicated by the fault LED alternating blue and amber); the fault LED remains solid amber.
Solution: The SP must be inserted firmly so that it will "seat" properly. Using the orange
release levers on the faulted SP, reseat the SP by sliding the SP out of the enclosure a few
inches and pushing it back in, being certain that the latches are fully closed to properly
seat the SP. Refer to “Task 8: Install the SP assemblies” on page 9.
Problem: When running svc_change_config --commit you see the following message:
You cannot commit the upgrade. Please verify that both SPs are
inserted, and both are running in service mode.
Solution: It takes somewhat longer for a newly inserted storage processor to complete
initialization and to reach service mode, than for the original storage processor, SP A. If
the fault LED on the back of SP B (the new storage processor) is not alternating amber and
blue after 20 minutes, then attempt to reinstall the storage processors (SP A and SP B):
1. Release the cable retention bail and unplug the power cord from each power supply.
2. Ensure all cables are labeled so they can be reconnected correctly.
3. Locate the two orange release levers on the SP B latches; squeeze the levers to release
the latches; and, then pull the latches outward.
4. Pull out the latches until they are fully extended and SP B is released from its
enclosure.
5. Use the latches to partially slide SP B from its enclosure.
When SP B is about half-way out of its enclosure, use both hands to support the
assembly and draw it fully out of the enclosure.
6. Follow steps 1-5 on SP A. Make sure to mark SP A with tape or some other means to
ensure that you return it to its original slot, and label all cables to ensure they are
reconnected correctly.
7. Remove and then reinstall the memory on SP A. Refer to “Task 6: Exchange the
memory modules” on page 8.
8. Remove and then reinstall the memory on SP B.

9. Reinstall SP A.
10. Reinstall SP B.
11. Reconnect all cables that were removed.
12. Reconnect the power cables to both SPs.
13. Continue with “Task 11: Validate the upgrade and reboot the system” on page 10.
Problem: You believe that you have a hardware problem, and want to abort the upgrade in
progress.
Solution: In the unlikely event that bad/damaged upgrade components were received and
your attempt to validate the upgrade failed, the upgrade may be aborted. You will need to
remove the parts that were added earlier in this procedure.
Note: Reviewyourdecisiontoaborttheupgradeprocedurewithyourserviceprovider.
1. From the service console in service mode, run command svc_change_config --abort.
It displays a message to restore the hardware to the previous configuration.
2. Wait for the prompt to return to the console window, which indicates that the service
script completed.
3. Release the cable retention bail and unplug the power cord from each power supply
(both SPs and any attached DAEs); and, label and remove all cables from both SPs.
4. Locate the two orange release levers on SP B latches.
5. Squeeze the levers to release the latches and then pull the latches outward.
6. Pull out the latches until they are fully extended and the SP B is released from its
enclosure.
7. Use the latches to partially slide SP B from its enclosure.
8. When SP B is about halfway out of its enclosure, use both hands to support SP B and
draw it fully out of the enclosure.
9. Place the SP B on a clean, flat, static-free work surface.
10. Return the cache protection module to slot B.
11. Locate the two orange release levers on the SP A latches.
12. Squeeze the levers to release the latches and then pull the latches outward.
13. Pull out the latches until they are fully extended and SP A is released from its
enclosure.
14. Use the latches to partially slide SPA from its enclosure.
15. When SP A is about halfway out of its enclosure, use both hands to support SP A and
draw it fully out of the enclosure.
Remove the new memory DIMMs placed in the DIMM slots on SP A and insert the
original memory DIMMs. Refer to “Task 6: Exchange the memory modules” on page 8.
16. Reconnect the power cables that were removed from any DAEs.
17. Reconnect all cables to SP A, including the power cable.
