ISO and Aruba Central (on-premises) Software Installation

The ISO installation can be performed only on Central-ready appliances. Aruba Central (on-premises)installation is a 3-stage process with multiple options in each stage:

Step 1: Install Aruba Central (On-Premises) ISO on the Server

• The installation can be done traditionally with DVD, monitor, and keyboard without the iLO interface.
• Using iLO Interface and placing the Aruba Central (On-Premises) ISO image on the PC.
• Using iLO interface and placing the Aruba Central (On-Premises) ISO image on HTTPSHypertext Transfer Protocol Secure. HTTPS is a variant of the HTTP that adds a layer of security on the data in transit through a secure socket layer or transport layer security protocol connection. server, which is reachable to the Aruba Central (On-Premises) iLO IP address.

Step 2: Install Aruba Central (On-Premises) Apps Package on the Server

The Apps package is uploaded on an SCPSecure Copy Protocol. SCP is a network protocol that supports file transfers between hosts on a network. server reachable to the Aruba Central (On-Premises) node IP address.

Step 3: Setting up a Cluster

• Assign permanent IP address and network settings to all the nodes.
• Cluster setup with all nodes.
• Proceed with Step 1 and 2 for the nodes that are part of Aruba Central (on-premises) cluster already.

Installing Aruba Central (on-premises) ISO Files on Central-Ready Airwave Appliance

There are 3 ways to install Aruba Central ISO to the Central Appliance:

• Using DVD
• Using the iLO interface with ISO image on the PC or Desktop
• Using the ISO image on an HTTPS server

Installing Aruba Central (on-premises) ISO Files Using DVD

Download the ISO image from the Aruba Support Portal and copy that ISO image into a bootable

DVD.

1. Connect a monitor and a keyboard to the server.
2. Insert the DVD in the DVD tray located at the front of the server and reboot the server using the ctrl+alt+del command on the keyboard.
3. Press F11 to navigate to the boot options.
4. Select the Legacy Bios mode. The server will reboot again.
5. Press option 1 to boot from the CD-ROM.

   

6. The ENTER to Legacy BIOS One-Time Boot Menu or ESC to cancel. Enter (exit) |ESC (Cancel) message is prompted. Click OK.

   

7. The server boots from the DVD and the ISO installation is complete.

Remove the DVD and reboot the server using the power button located at the front of server. Continue with the Central Apps package installation. For more information, see Installing Central Apps (Package Installation). For information about the boot process and iLO upgrade, see Installation Guide- Technotes.

If the user is unable to login to Aruba Central (on-premises) after the ISO installation, reset the ILO through the ILO user interface. For more information, see Resetting iLO.

Resetting iLO

Perform the following steps to reset the iLO, if the user is unable to login to Aruba Central (on-premises) after performing the ISO installation:

1. Log into iLO user interface using the username and password.

2. Go to the Information > Diagnostics tab and click Reset.

Installing Aruba Central (on-premises) ISO Files Using the iLO interface with ISO image on the PC

1. Obtain the iLO IP address assigned statically or by DHCPDynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network. .
2. Log into iLO IP address using the username and password on top of the server.
3. On the iLO's Overview page, you can see that the appliance has Trusted Platform Module (TPMTrusted Platform Module. TPM is an international standard for a secure cryptoprocessor, which is a dedicated microcontroller designed to secure hardware by integrating cryptographic keys into devices.) enabled. If the option is not present or not enabled, Aruba Central software cannot be installed on the server.
4. The iLO Firmware version is 2.18, which is required for Aruba Central 2.5.3 version. However, on older appliance, the iLO Firmware may be 1.40 or lower versions. Post ISO installation, the Aruba Central software will update the iLO Firmware too.

   

5. Set the Boot process to CD/DVD Drive from Administration > Boot order. Use the Up or Down button to move the CD/DVD Drive and click Apply.

   

6. Download the ISO image to the computer.
7. Connect to the Java Web Console or HTML console on the iLO.
8. Select the Disc icon > CD/DVD > Local *.iso file.
9. Browse and select the ISO file from the computer and the ISO file is mounted to the server.

   

10. Reboot using the iLO icon > Power > Reset. The server boots up with ISO image and installs the Aruba Central OS.

    

11. Reboot post the installation and proceed to Central Apps package installation. For more information, see Installing Central Apps (Package Installation). For information about the boot process and iLO upgrade, see Aruba Central (on-premises) Installation Guide-Technotes.

Installing Aruba Central (on-premises) ISO Files Using the ISO image on an HTTPS server

1. Get the iLO IP address assigned statically or by DHCP.
2. Log Into iLO IP using the username and password on top of the server.
3. Set the Boot process to CD/DVD Drive from Administration > Boot order. Click the Up and Down button to move the CD/DVD Drive to top and click Apply.

   

4. Download the ISO image to an HTTPS server accessible from iLO IP address.
5. Connect to the Java Web Console or HTML.
6. Select Virtual Drives > URL CD/DVD-ROM.

   

7. Copy paste the HTTPS link for the ISO image.

   

8. After the file is attached, reboot the server from Power Switch > Reset option. The server after the initial boot process should boot from the CD-ROM. The ISO installation takes about 25 minutes when using a bootable disk. If you are using ILO, the time depends on the network speed and VPNVirtual Private Network. VPN enables secure access to a corporate network when located remotely. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security, and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two. connection, if used remotely either from PC or using HTTPS server. For more information on the boot process, see Aruba Central (on-premises) Installation Guide-Technotes.

It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element. server IP address
   • Secondary DNS server address (optional)
