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.
Replace E5700 battery
You can replace a failed battery in an E5700 storage system.
About this task
Each E5700 controller canister includes a battery that preserves cached data if the AC power fails. If the
Recovery Guru in SANtricity System Manager reports either a Battery Failed status or a Battery Replacement
2

Required status, you must replace the affected battery.
Before you begin
•Verify that no volumes are in use or that you have a multipath driver installed on all hosts using these
volumes.
•Review Requirements for E5700 battery replacement.
What you’ll need
•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.)
Step 1: Place controller offline (duplex)
If you have a duplex configuration, place the affected controller offline so you can safely remove the failed
battery. The controller that you are not placing offline must be online (in the optimal state).
Perform this task only if your storage array has two controllers (duplex configuration).
Steps
1. 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.
2. From the Details area of the Recovery Guru, determine which battery to replace.
3. 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.
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 SANtricity 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";
4. 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.
5. 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
6. 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.
Step 2: Remove controller canister
Before you can remove the failed battery, you must remove the controller canister.
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 of the cables from the controller canister.
To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
4. If the host ports on the controller canister use SFP+ transceivers, leave them installed.
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:

(2) Cam handle
7. Using two hands and the cam handle, slide the controller canister out of the shelf.
Always use two hands to support the weight of a controller canister.
If you are removing the controller canister from an E5724 controller shelf, a flap swings into place to block
the empty bay, helping to maintain air flow and cooling.
8. Turn the controller canister over, so that the removable cover faces up.
9. Place the controller canister on a flat, static-free surface.
Step 3: Remove failed battery
After removing the controller canister from the controller shelf, remove the battery.
Steps
1. Remove the controller canister’s cover by pressing down on the button and sliding the cover off.
2. Confirm that the green LED inside the controller (between the battery and the DIMMs) is off.
If this green LED is on, the controller is still using battery power. You must wait for this LED to go off before
removing any components.

5. Lift up on the battery, and slide it out of the controller canister.
6. Follow the appropriate procedures for your location to recycle or dispose of the failed battery.
To comply with International Air Transport Association (IATA) regulations, never ship a
lithium battery by air unless it is installed within the controller shelf.
Step 4: Install new battery
After removing the failed battery, install a new one.
Steps
1. Unpack the new battery, and set it on a flat, static-free surface.
To comply with IATA safely regulations, replacement batteries are shipped with a state of
charge (SoC) of 30 percent or less. When you reapply power, keep in mind that write
caching will not resume until the replacement battery is fully charged and it has completed
its initial learn cycle.
