Changing the Host Protocol in the E5600 or EF560 by

Replacing Hardware Components

When you change the host protocol of an E5612, E5624, or E5660 storage array or an EF560 flash array by replacing hardware

components, you must power off the storage array or flash array, remove hardware, install new hardware, and reapply power.

Before starting the procedure, be aware of the following:

• You must review the information in

Understanding the options for changing the host protocol

on page 2 to learn about the

different methods for changing the host protocol and to confirm that you are using the correct instructions for your situation.

• Because the power must be off when you upgrade hardware to change the host protocol, you must schedule a downtime

maintenance window for this procedure. You cannot access data on the storage array or flash array until you have

successfully completed the upgrade.

• You must obtain any new cables, transceivers, switches, and host bus adapters (HBAs) needed for the new host protocol. You

must install any new host hardware before you can connect the storage array or flash array to the hosts.

Attention: After installing the new hardware, you must inform NetApp technical support about the change to the hardware

configuration by sending an upgrade notification. This notification ensures that you receive correct replacement parts if you

need them later.

Understanding the options for changing the host protocol

Review the options for changing the host protocol in an E5600 storage array or an EF560 flash array to confirm that you are

following the correct steps.

The following figure provides a high-level overview of the options for changing the host protocol of an E5600 storage array or

an EF560 flash array.

Key Option Description

Hardware

upgrade You must replace hardware to change the protocol.

Note: For most hardware upgrades, you need to replace only the HICs;

however, if you currently use iSCSI, Fibre Channel, or Fibre Channel-

iSCSI split protocol, you might need to replace the controller canisters,

which include the HICs. The exact procedure you need to follow depends

on your Replacement Part Number. Refer to

Determining the Replacement

Part Number

on page 3.

Software

feature pack

conversion

You can apply a software feature pack in SANtricity Storage Manager to

change the protocol.

Important: This document does not describe how to perform software

feature pack conversions. For those instructions, use one of the documents

listed at the end of this topic.

As the figure indicates, there are three methods for changing the host protocol. You might need to:

• Upgrade hardware components (the paths shown with the solid, blue arrows)

• Perform a software feature pack conversion (the paths shown with the dotted, green arrows)

• Perform both a hardware upgrade and a feature pack conversion. For example, if you want to change the protocol from SAS

to Infiniband (IB), and you want to use iSCSI RDMA Protocol (SRP) instead of iSCSI Extensions for Remote Direct

Memory Access (iSER), you must follow a two-step process:

1. Upgrade the hardware to change the HICs from SAS to IB-iSER (this is the IB HIC's default protocol).

2Changing the Host Protocol in the E5600 or EF560 by Replacing Hardware Components

2. Perform a software feature pack conversion to convert the IB protocol from iSER to SRP.

Determining the Replacement Part Number

For most hardware upgrades to change the host protocol, you need to replace only the HICs. However, if you are currently using

Fibre Channel (FC) , iSCSI, or FC-iSCSI split protocol, you might need to replace the controller canisters, which include the

HICs. The exact procedure you need to follow depends on your Replacement Part Number, which is displayed in SANtricity

Storage Manager.

About this task

If you currently use FC, SCSI, or FC-iSCSI split protocol, follow these steps to locate the Replacement Part Number.

Note:

If you currently use SAS or IB protocol, you can skip this section.

Steps

1. In the Array Management Window, click the Hardware tab.

2. In the Base Controller Properties section, check the value for Replacement Part Number.

3. Look at the Replacement Part Number to determine whether you must upgrade both controller canisters or whether you can

upgrade only the HICs:

• If the Replacement Part Number is E-X561206A-R6 or EF-X561206A-R6, you must replace the controller canisters,

which include the HICs.

• If the Replacement Part Number is any other value, you can remove the HICs from the existing controller canisters and

install new HICs.

Procedures for changing the host protocol

Before changing the host protocol in your E5600 storage array or EF560 flash array, confirm that you understand the general

steps.

6Changing the Host Protocol in the E5600 or EF560 by Replacing Hardware Components

Managing Synchronous Mirroring

The Synchronous Mirroring feature (also referred to as RVM) is supported only for Fibre Channel.

About this task

If you are currently using Synchronous Mirroring and want to change from Fibre Channel to any other protocol, you must delete

any synchronous mirrored pairs and deactivate any synchronous mirroring relationships.

Attention: If you do not deactivate these relationships before upgrading the HICs, your system loses data access and data loss

might occur.

Steps

1. In the Array Management Window, select Help > Contents, and search for the topics related to Synchronous Mirroring.

2. Follow the instructions in the online help to identify all synchronous mirroring volumes that might exist.

3. In the Logical pane, right-click a synchronous mirroring volume, and select Copy Services > Synchronous Mirroring >

Remove Mirror Relationship.

4. Select all volumes, and click Remove.

5. After you delete all mirroring relationships, deactivate Synchronous Mirroring by selecting Copy Services > Mirroring >

Deactivate.

6. Select the synchronous mirroring check box from the pop-up window.

Attention: If you do not delete all mirroring relationships before deactivating mirroring, you receive an error.

Managing Asynchronous Mirroring

The Asynchronous Mirroring feature (also referred to as ARVM) is supported only for iSCSI and Fibre Channel.

About this task

If you are currently using asynchronous mirroring relationships and want to change the protocol to IB or SAS, you must delete

the mirrored pairs and deactivate the asynchronous mirroring relationships.

Steps

1. In the Array Management Window, access the online help and search for the topics related to Asynchronous Mirroring.

2. Follow the instructions in the online help to remove all asynchronous mirrored pairs from the asynchronous mirror groups.

Note: When removing each pair, select the Delete all repositories associated with this mirrored pair check box.

3. Follow the instructions in the online help to delete all asynchronous mirror groups.

Cabling considerations

Before upgrading hardware, confirm that your replacement cables and any SFPs or QSFPs are compatible with the connectors

on the new HICs.

Preparing to upgrade hardware

You must perform a number of steps to prepare your system for changing the host protocol by upgrading hardware, including

stopping host I/O operations, issuing a CLI command to remove any previously applied software feature packs, and saving the

chassis serial number. If you use the Drive Security feature and you are replacing controller canisters, you also must save the

drive security key.

Before you begin

• If you are changing the protocol to iSCSI or IB-SRP, you must have disabled Data Assurance on all volumes.

• If you were using Asynchronous Mirroring or Synchronous Mirroring, you have deleted all mirrored pairs and deactivated

all mirroring relationships, where applicable.

Steps

1. Gather support data about your storage array by using one of these methods:

• Use the storage management software to collect and save a support bundle of your storage array. From the Array

Management Window toolbar, select Monitor > Health > Collect Support Data Manually. Then, name and specify a

location on your system where you want to store the support bundle.

• Use the command-line interface (CLI) to run the save storageArray supportData command. From the Enterprise

Management Window, select the storage array, and select Tools > Execute Script. In the Script Editor dialog box, enter

the following command, and select Tools > Verify and Execute from the menu:

save storageArray supportData;

8Changing the Host Protocol in the E5600 or EF560 by Replacing Hardware Components

Note: Gathering support data can temporarily impact performance on your storage array.

2. Ensure that no I/O operations are occurring between the storage array and all connected hosts. For example, you can perform

these steps:

• Stop all processes that involve the LUNs mapped from the storage to the hosts.

• Ensure that no applications are writing data to any LUNs mapped from the storage to the hosts.

• Unmount all file systems associated with volumes on the array.

Note: The exact steps to stop host I/O operations depend on the host operating system and the configuration, which are

beyond the scope of these instructions. If you are not sure how to stop host I/O operations in your environment, consider

shutting down the host.

Attention: Possible data loss – If you continue this procedure while I/O operations are occurring, you might lose data.

3. If the storage array participates in a mirroring relationship, stop all host I/O operations on the secondary storage array.

4. Wait for five minutes to allow any data in cache memory to be flushed to disk.

5. From the title bar of the Array Management Window, select Monitor > Reports > Operations in Progress.

6. Wait for all operations shown on the Operations in Progress window to complete before continuing with the next step.

7. Follow these steps to disable any feature packs that might have been applied to the storage array in manufacturing or after

you received the system:

a. From the Enterprise Management Window in SANtricity Storage Manager, select the storage array.

b. Select Tools > Execute Script.

The Script Editor dialog box is displayed.

c. Type the following command:

disable storageArray featurePack;

d. From the menu, select Tools > Verify and Execute.

Preparing to upgrade hardware 9

The command syntax is verified, and the command is executed.

8. Record the chassis serial number for your storage array, as follows:

Note: You must have this number to send an upgrade notification to NetApp technical support indicating that you have

changed the configuration.

a. In the Enterprise Management Window tree view, double-click your storage array.

b. In the Summary tab of the Array Management Window, click the View Storage Array Profile link.

c. Copy the value for Chassis Serial Number, and paste it into a text file.

9. If you are using the Drive Security feature and you are replacing the controller canisters, follow these steps to save the drive

security key:

a. Go to the Array Management Window.

b. From the Storage Array menu, select Security > Drive Security > Save Key.

c. Save the security key to a location not on your storage array.

Powering down

After preparing to upgrade the hardware, you can power down the storage array or flash array.

Before you begin

• You must have collected a support bundle.

• You must have stopped host I/O operations and confirmed that no operations are in process.

• You must have removed all feature packs.

• You must have saved the chassis serial number to a file.
