Introduction

This guide contains instructions for managing VxRack System FLEX after installation at the customer site.

The target audience for this document includes those responsible for managing VxRack FLEX, including

the system administrator and Dell EMC personnel responsible for remote management of VxRack FLEX.

The document assumes that the person administering VxRack FLEX:

•Is familiar with VMware, ScaleIO, and Cisco networking technologies

•Is familiar with VxRack FLEX concepts and terminology

•Has VxRack FLEX troubleshooting skills

Refer to Glossary for terms, definitions, and acronyms.

Introduction | 4

Managing VMware vSphere operations

Use the VMware vSphere Web Client to perform tasks such as the following on the VxRack System

FLEX:

•Monitor VSAN

•Manage servers and hosts. Refer to vCenter Server and Host Management in the VMware

vSphere 6.0 Documentation Center.

•Administer VMware vSphere. Refer to vSphere Administration with the vSphere Client in the

VMware vSphere 6.0 Documentation Center.

Logging on to the VMware vSphere Web Client

The VMware vSphere Web Client enables you to connect to the VMware vCenter Server system to

manage VMware ESXi hosts through a browser.

About this task

Use this procedure to log on to the VMware vSphere Web Client on the VxRack Controller.

Procedure

1Using a web browser, launch the VMware vSphere Web Client. Refer to the customer's Logical

Configuration Survey for the required (vCSA) URL.

2When prompted, type the username and password.

3Click Login.

Monitoring VSAN

Use this procedure to monitor VSAN on the VxRack Controller.

About this task

Exercise caution when accessing the VxRack Controller VMware vCenter. Do not make any

configuration changes other than those documented as it may result in loss of monitoring and

remote support capabilities.

Procedure

1Log on to the VMware vSphere Web Client.

2Click Hosts and Clusters.

3Click the cluster hosting the VxRack Controller nodes.

4Click Manage > Settings > Virtual VSAN > General.

5 | Managing VMware vSphere operations

5Verify the VSAN status:

aEnsure it displays the correct number of flash drives and data disks.

bEnsure the network status displays normal.

6Click Monitor > Virtual SAN > Health.

7Verify all test results display Passed. If a test result displays Warning or Failed, investigate and

troubleshoot the cause.

Managing ScaleIO operations

You can provision, maintain, and monitor ScaleIO using the following management tools:

•Graphical User Interface (GUI)

•Command Line Interface (CLI)

•VMware plug-in

Refer to the ScaleIO User Guide for detailed procedural information for each of the management tools.

Graphical User Interface (GUI)

The ScaleIO GUI enables you to perform standard configure and maintain activities, as well as monitor

the storage system's health and performance. You can use the GUI to view the entire system and then

drill down to different elements.

Procedure

1To identify which Meta Data Manager (MDM) is the Master, open the ScaleIO Plugin within

VMware vCenter. Navigate to ScaleIO Systems, and select the system in the left pane, then

select the Summary tab. The manager that does not show a state status of normal is the Master

MDM.

2Use a remote desktop session and the applicable IP address or hostname, as identified in the

customer's Logical Configuration Survey (LCS), to log on to the VxRack Controller jump server.

3Click the ScaleIO icon on the desktop to launch the GUI.

4Type the following details:

aManagement IP address or host name of the Master MDM.

bUser name

cPassword

What to do next

Refer to the ScaleIO User Guide for information about using the GUI.

Command Line Interface (CLI)

The CLI enables you to configure, maintain, monitor the ScaleIO system, and map volumes.

To use the CLI commands, use SSH to access the MDM. To identify which MDM is the Master,

open the ScaleIO Plugin within VMware vCenter. Navigate to ScaleIO Systems, select the

system in the left pane, and select the Summary tab. The Manager that does not show a state

status of Normal is the Master MDM.

7 | Managing ScaleIO operations

When adding a volume, if you use the --storage_pool_id parameter in the command, it is not

necessary to specify the Protection Domain ID/name and the Storage Pool name.

Refer to the ScaleIO User Guide for information about using the CLI.

VMware plug-in

The VMware plug-in enables you to provision and maintain the ScaleIO environment. It is the

recommended tool to use when carrying out front-end tasks, such as creating and mapping volumes.

About this task

Use this procedure to log on to the VMware plug-in.

Procedure

1Using a web browser, launch the VMware vSphere Web Client. Refer to the customer's Logical

Configuration Survey for the required (vCSA) URL.

2Log on with administrative privileges.

3From the Home tab, click the ScaleIO icon.

What to do next

Refer to the ScaleIO User Guide for information about using the plug-in.

Collecting ScaleIO logs

Collecting ScaleIO logs using the Installation Manager web client

Use this procedure to gather ScaleIO logs from all nodes using the Installation Manager web client.

Before you begin

Obtain the administrator username and password for the Installation Manager.

Procedure

1Log on to the VMware vSphere Web Client.

2Click SIO plugin > ScaleIO Systems.

3Right-click the ScaleIO System and click Open ScaleIO Gateway to launch the ScaleIO

Gateway/Installation Manager.

4Log on to the ScaleIO Gateway.

5Click Maintain.

Managing ScaleIO operations | 8

6Type the Master Meta Data Manager (MDM) IP address and password, and the Lightweight

Installation Agent (LIA) password.

7Click Retrieve system topology.

8Click Get Info.

9Type the MDM password and enable the options as necessary.

10 When the process is complete, click Download logs to download the log files.

11 Click Mark operation completed.

Collecting ScaleIO logs using the Installation Manager Command Line

Interface (CLI)

Use this procedure to gather ScaleIO logs using the Installation Manager CLI.

Before you begin

•Download the CLI from the ScaleIO Home screen.

•Obtain the administrator username and password for the Installation Manager.

Procedure

1Log on to the Installation Manager server using the CLI:

java -jar install-CLI.jar

im login --username admin --password <gateway admin password> --host <gateway IP

address> --no certificate validation true

2Run the get_info command:

im get_info --mdm_ip <master mdm ip> --mdm_password <MDM password> --lia password <LIA

password> --output_path <output path> --non_interactive yes

3Gather the logs for the specific node:

aOn a Linux node, use the get_info.sh command:

iOn the Master Meta Data Manager (MDM) node, type:

/opt/emc/scaleio/mdm/diag/get_info.sh -u admin -p <MDM_password> -d

<output_path>

ii On the Slave MDM node, type:

9 | Managing ScaleIO operations

/opt/emc/scaleio/<component_name>/diag/get_info.sh -d <output_path

where the <component_name> can be mdm, tb, or sds.

The get_info.sh command removes everything in the <output_path>.

Ensure you back up any files you want to keep before running the command.

bOn an SDC node, the Installation Manager collects only the drv_cfg.txt file. Use the

following commands to check the basic configuration and state:

/opt/emc/scaleio/sdc/bin/drv_cfg --query_mdms

/opt/emc/scaleio/sdc/bin/drv_cfg --query_tgts

/opt/emc/scaleio/sdc/bin/drv_cfg --query_vols

Configuring ScaleIO features

VxRack System FLEX supports the following ScaleIO features:

•Extended 5-node Meta Data Manager (MDM) cluster

•LDAP user authentication

•In-flight checksum

•Public and private key pair authentication

•Instant maintenance mode

•ESRS integration

For information on configuring ScaleIO features, refer to ScaleIO documentation located at

support.emc.com.
