E5700
Maintain E5700 hardware
For the E5700 storage system, you can perform maintenance procedures on the
following components.
Batteries
A battery is included with a controller canister and preserves cached data if the AC power fails.
Controllers
A controller consists of a board, firmware, and software. It controls the drives and implements the System
Manager functions.
Canisters
Canisters consist of three different types: power-fan canisters (power supplies) that supply a redundant power
source and adequate cooling in a 12-drive or 24-drive controller shelf or drive shelf; power canisters that are
used for power redundancy in a 60-drive controller shelf or drive shelf; and fan canisters that are used for
cooling the 60-drive controller shelf or drive shelf.
Drives
A drive is an electromagnetic mechanical device that provides the physical storage media for data.
Host interface cards (HICs)
A host interface card (HIC) can optionally be installed within a controller canister. The E5700 controller
includes built-in host ports on the controller card itself, as well as host ports on the optional HIC. Host ports that
are built into the controller are called baseboard host ports. Host ports that are built into the HIC are called HIC
ports.
Host port protocol
You can convert the protocol of a host to a different protocol so that compatibility and communication can be
established.
Batteries
Requirements for E5700 battery replacement
Before you replace an E5700 battery, review the requirements and considerations.
Each controller canister includes a battery that preserves cached data if the AC power fails.

Recovery Guru alerts
If the Recovery Guru in SANtricity System Manager reports one of following statuses, you must replace the
affected battery:
•Battery Failed
•Battery Replacement Required
From SANtricity System Manager, review the details in the Recovery Guru to confirm that there is an issue with
a battery and to ensure no other items must be addressed first.
Procedure overview
To protect your data, you must replace a failed battery as soon as possible.
The following is an overview of the steps to replace a battery in E5700 controllers (E5724, EF570, or E5760):
1. Take controller offline (duplex only).
2. Remove the controller canister.
3. Replace the battery.
4. Replace the controller canister.
5. Bring the controller online (duplex only).
Requirements
If you plan to replace a failed battery, you must have:
•A replacement battery.
•An ESD wristband, or you have taken other antistatic precautions.
•Labels to identify each cable that is connected to the controller canister.
•A management station with a browser that can access SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Optionally, you can use the command line interface (CLI) to perform some of the procedures. If you do not
have access to the CLI, you can do one of the following:
◦For SANtricity System Manager (version 11.60 and above) — Download the CLI package (zip file)
from System Manager. Go to Settings ›System ›Add-ons ›Command Line Interface. You can then
issue CLI commands from an operating system prompt, such as the DOS C: prompt.
◦For SANtricity Storage Manager/Enterprise Management Window (EMW) — Follow the instructions
in the express guide to download and install the software. You can run CLI commands from the EMW
by selecting Tools ›Execute Script.

Controllers
Requirements for E5700 controller replacement
Before you replace an E5700 controller, review the requirements and considerations.
Each controller canister contains a controller card, a battery, and an optional host interface card (HIC).
Procedure overview
When you replace a failed controller canister, you must remove the battery and HIC, if one is installed, from the
original controller canister, and install them in the replacement controller canister.
You can determine if you have a failed controller canister in two ways:
•The Recovery Guru in SANtricity System Manager directs you to replace the controller canister.
•The amber Attention LED on the controller canister is on, indicating that the controller has a fault.
This procedure applies to IOM12 and IOM12B drive shelves.
13

This procedure is for like-for-like shelf IOM hot-swaps or replacements. This means you can
only replace an IOM12 module with another IOM12 module or replace an IOM12B module with
another IOM12B module. (Your shelf can have two IOM12 modules or have two IOM12B
modules.)
(1) Attention LED
The figure shows an example controller canister; the host ports on your controller canister might
be different.
Requirements for replacing a failed controller
Before you replace a controller, you must have:
•A replacement controller canister with the same part number as the controller canister you are replacing.
•An ESD wristband, or you have taken other antistatic precautions.
•Labels to identify each cable that is connected to the controller canister.
•A #1 Phillips screwdriver.
•A management station with a browser that can access SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Optionally, you can use the command line interface (CLI) to perform some of the procedures. If you do not
have access to the CLI, you can do one of the following:
◦For SANtricity System Manager (version 11.60 and above) — Download the CLI package (zip file)
from System Manager. Go to Settings ›System ›Add-ons ›Command Line Interface. You can then
issue CLI commands from an operating system prompt, such as the DOS C: prompt.
◦For SANtricity Storage Manager/Enterprise Management Window (EMW) — Follow the instructions
in the express guide to download and install the software. You can run CLI commands from the EMW
by selecting Tools ›Execute Script.
14

Duplex configuration requirements
For a controller shelf with two controllers (duplex configuration), you can replace a controller canister while
your storage array is powered on and performing host I/O operations, as long as the following conditions are
true:
•The second controller canister in the shelf has Optimal status.
•The OK to remove field in the Details area of the Recovery Guru in SANtricity System Manager displays
Yes, indicating that it is safe to remove this component.
Replace controller in duplex configuration
You can replace a controller canister in a duplex (two-controller) configuration, for the
following controller shelves:
•E5724 controller shelf
•E5760 controller shelf
About this task
Each controller canister contains a controller card, a battery, and an optional host interface card (HIC). When
you replace a controller canister, you must remove the battery and HIC, if one is installed, from the original
controller canister, and then install them in the replacement controller canister.
This task is only for storage arrays with two controllers (duplex configuration).
This procedure applies to IOM12 and IOM12B drive shelves.
This procedure is for like-for-like shelf IOM hot-swaps or replacements. This means you can
only replace an IOM12 module with another IOM12 module or replace an IOM12B module with
another IOM12B module. (Your shelf can have two IOM12 modules or have two IOM12B
modules.)
What you’ll need
•A replacement controller canister with the same part number as the controller canister you are replacing.
(See step 1 to verify the part number.)
•An ESD wristband, or you have taken other antistatic precautions.
•#1 Phillips screwdriver.
•Labels to identify each cable that is connected to the controller canister.
•A management station with a browser that can access SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Step 1: Prepare to replace controller (duplex)
Prepare to replace a controller canister by verifying that the replacement controller canister has the correct
FRU part number, backing up the configuration, and collecting support data. If the controller is still online, you
must take it offline.
Steps
1. Unpack the new controller canister, and set it on a flat, static-free surface.
15

Save the packing materials to use when shipping the failed controller canister.
2. Locate the MAC address and FRU part number labels on the back of the controller canister.
(1) MAC address: The MAC address for management port 1 (“P1”). If you used DHCP to obtain the original
controller’s IP address, you need this address to connect to the new controller.
(2) FRU part number: This number must match the replacement part number for the currently installed
controller.
3. From SANtricity System Manager, locate the replacement part number for the controller canister you are
replacing.
When a controller has a fault and needs to be replaced, the replacement part number is displayed in the
Details area of the Recovery Guru. If you need to find this number manually, follow these steps:
a. Select Hardware.
b. Locate the controller shelf, which is marked with the controller icon .
c. Click the controller icon.
d. Select the controller, and click Next.
e. On the Base tab, make a note of the Replacement Part Number for the controller.
4. Confirm that the replacement part number for the failed controller is the same as the FRU part number for
the replacement controller.
Possible loss of data access — If the two part numbers are not the same, do not attempt
this procedure. In addition, if the failed controller canister includes a host interface card
(HIC), you must install that HIC into the new controller canister. The presence of
mismatched controllers or HICs causes the new controller to lock down when you bring it
online.
5. Back up the storage array’s configuration database using SANtricity System Manager.
If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.
16

The system will save the current state of the RAID configuration database, which includes all data for
volume groups and disk pools on the controller.
◦From System Manager:
a. Select Support ›Support Center ›Diagnostics.
b. Select Collect Configuration Data.
c. Click Collect.
The file is saved in the Downloads folder for your browser with the name, configurationData-
<arrayName>-<dateTime>.7z.
◦Alternatively, you can back up the configuration database by using the following CLI command:
save storageArray dbmDatabase sourceLocation=onboard contentType=all
file="filename";
6. Collect support data for your storage array using SANtricity System Manager.
If a problem occurs when you remove a controller, you can use the saved file to troubleshoot the issue. The
system will save inventory, status, and performance data about your storage array in a single file.
a. Select Support ›Support Center ›Diagnostics.
b. Select Collect Support Data.
c. Click Collect.
The file is saved in the Downloads folder for your browser with the name, support-data.7z.
7. If the controller is not already offline, take it offline now using SANtricity System Manager.
◦From SANtricity System Manager:
a. Select Hardware.
b. If the graphic shows the drives, select Show back of shelf to show the controllers.
c. Select the controller that you want to place offline.
d. From the context menu, select Place offline, and confirm that you want to perform the operation.
If you are accessing SANtricity System Manager using the controller you are
attempting to take offline, a SANtricity System Manager Unavailable message is
displayed. Select Connect to an alternate network connection to automatically
access SANtricity System Manager using the other controller.
◦Alternatively, you can take the controllers offline by using the following CLI commands:
For controller A: set controller [a] availability=offline
For controller B: set controller [b] availability=offline
8. Wait for SANtricity System Manager to update the controller’s status to offline.
Do not begin any other operations until after the status has been updated.
17

9. Select Recheck from the Recovery Guru, and confirm that the OK to remove field in the Details area
displays Yes, indicating that it is safe to remove this component.
Step 2: Remove controller canister (duplex)
Remove a controller canister to replace the failed canister with a new one.
Steps
1. Put on an ESD wristband or take other antistatic precautions.
2. Label each cable that is attached to the controller canister.
3. Disconnect all the cables from the controller canister.
To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
4. If the controller canister has a HIC that uses SFP+ transceivers, remove the SFPs.
Because you must remove the HIC from the failed controller canister, you must remove any SFPs from the
HIC ports. However, you can leave any SFPs installed in the baseboard host ports. When you reconnect
the cables, you can move those SFPs to the new controller canister.
5. Confirm that the Cache Active LED on the back of the controller is off.
6. Squeeze the latch on the cam handle until it releases, and then open the cam handle to the right to release
the controller canister from the shelf.
The following figure is an example of an E5724 controller shelf:
