The VAST Web UI installer performs configuration of all hosts in the cluster. Switch configuration is an optional step in the installer designed to be skipped if your architecture features only non-managed switches or if you prefer to configure switches separately before you run the installer.
-
Connect your laptop to the technician port on any one of the CNodes. This CNode will become the Management CNode.
The technician port is usually the right of the two RJ-45 ports on the front panel (refer to the installation plan since this may vary.)
-
Run the following commands to copy the VAST Cluster package file (e.g. vast-12345.tar) and the vast_bootstrap.sh script to the CNode.
scp <package file> vastdata@192.168.2.2:/vast/bundles/ scp <bootstrap file path> vastdata@192.168.2.2:/vast/bundles/
where
<package file path>
is the local path to the package file and<bootstrap file path>
is the local path to the file vast_bootstrap.sh.You'll be prompted for the password on running each command. The default password is vastdata.
-
Run the
vast_bootstrap.sh
script remotely over SSH:ssh vastdata@192.168.2.2 cd /vast/bundles ./vast_bootstrap.sh
-
Confirm the action:
Are you sure? this will wipe the current system [Y/n] y
The script opens the package and extracts the Vast Management Server (VMS) image and the vman.sh script. If the OS version on the CNode does not match the OS version in the package, the script upgrades the OS.
The script installs VMS on the CNode, reformats the CNode, and sets the management VIP on the CNode to 192.168.2.2.
The script also initiates discovery of all CNodes and DNodes. However, no hosts are actually discovered at this stage unless the switches were already configured before you began this procedure.
-
If OS upgrade occurs, your session will be disconnected. Run vast_bootstrap.sh again.
-
When the bootstrap script is complete, browse to https://192.168.2.2.
The VAST Web UI opens and displays the login screen.
-
Log in using the default admin user credentials:
-
Username: admin
-
Password: 123456
The Installation dialog opens.
Note
If the Installation dialog does not open automatically, click this spinner icon at the top right of the page to launch it:
-
-
In the Scheme Settings (Step 1 out of 4) screen, select a scheme file from the All Schemes dropdown. If the predefined scheme files are not suitable for the installation, click the Upload scheme button and upload a customized scheme file. Then select the uploaded scheme from the All Schemes dropdown.
For help selecting or creating a scheme file, see Prepare a Scheme File.
When the file is uploaded, the fields defined in the scheme appear with the values set in the scheme file pre-filled.
-
Optionally make changes if needed to those of the following fields that were loaded from the scheme:
-
Click Next.
If switches were already configured before you ran the bootstrap script, continue with Define Hosts (Step 2 out of 4) (Switches Configured).
If switches are not yet configured, continue with Define Hosts (Step 2 out of 4) (Switches Not Yet Configured).
The discovered hosts are displayed as CNodes and DNodes available to include in the cluster:

Hosts are identified with the following details:
1 |
Node type. CNode or DNode. |
2 |
IP address. This is usually an IPv6 address. |
3 |
Host name. |
4 |
MAC address. |
You can use the CNode and Dnode buttons to filter the discovered nodes list to display one or other type of host.
The Errors list displays any host errors that were detected during validation checks. Errors may pertain to CPU, memory, disks, NVRAMs and/or port connectivity. All discovered nodes are included by default in the Included hosts list.
Proceed as follows:
-
Review any host validation errors that may be listed to the right of the discovered host list under Errors(#). Consider identifying affected hardware components and doing field replacements to resolve errors. The error text refers to the affected host's factory default host name and IP address, enabling you to match each error to a host listed on the left. Using the MAC address included in the discovered hosts list, you can identify the affected host in the field.
-
After doing any field replacements, click Refresh Hardware to repeat host discovery and validation checks. Wait for the refresh to complete and then review validation errors again.
-
In case of validation errors that cannot be resolved on site before continuing and are critical, you can identify the affected host and exclude it from the installation. In this case, please report the errors to Support and arrange return and replacement of hardware. Replacement nodes can be added to the cluster once it is already active.
To exclude a host:
-
Click Next and continue with Required fields (Step 3 out of 4).
-
Configure each switch's management port with IP 192.168.15.15.
On each switch:
-
Detach the management cable from the switch management port.
-
Connect the laptop to the switch management port.
-
Run the following commands to configure the IP:
enable conf t interface mgmt0 no dhcp ip addr 192.168.15.15 /24 exit
Note
The user name and password for accessing the switch are admin and admin.
-
Reconnect the management cable to the switch management port.
-
-
Click Configure Switches. A button appears for configuring each switch pair in the scheme. The button names reflect the role of each switch pair:
-
Spine. A pair of switches that will be connected to the client network. (All schemes have at least one switch pair in this role.)
-
Leaf. A pair of switches that will not to be connected to the client network.
-
-
Click one of the buttons and complete the following fields to configure one switch pair:
-
Click Set.
-
Repeat the previous two steps for each switch pair.
-
When you've completed all switch pair configurations, click Set.
The following message appears:
-
Temporarily disconnect any cables from the management port of the management CNode and from the management port of data switch 1.
-
Connect a cable from the management port of the management CNode to the management port of data switch 1 and then click Apply.
Wait while VAST Cluster applies the configuration to the switch. While you're waiting, the screen displays "Applying...".
-
When a request to connect the cable to switch 2 appears, disconnect the cable from data switch 1. Disconnect the management switch cable from the management port of data switch 2 and connect the cable from the CNode management port to data switch 2.
-
Click Apply.
Wait while VAST Cluster applies the configuration to the switch. While you're waiting, the screen displays "Applying...".
-
Remove the cable you used to configure the data switches from the management port of the management CNode.
-
In the Define hosts (Step 2 out of 4) screen, click Refresh Hardware.
This runs host discovery.
-
Proceed now with Define Hosts (Step 2 out of 4) (Switches Configured).
-
Complete these fields:
-
If the installation requires a change from any other parameter from its default on the VMS server, click Advanced Settings.
Several parameters appear under Common advanced settings. Enter values as needed for any of those parameters.
If you want to set a different parameter, add the parameter name and value in the Advanced settings - added by you section.
-
If you are in Advanced settings, click Set & Back.
-
Click Finish. Review the summary and then click Install.
-
Monitor the task progress from the Activities page.
-
When the task is complete, the Activities page indicates that the VMS is available on the VMS VIP. Redirect your browser to the management VIP.
The cluster comes online. You'll see the cluster name at the top left of the page with the status "Online":
