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.

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.
