QoreStor 7.4.0 - Azure Deployment Guide

Accessing and configuring the virtual machine

*
NOTE: If you recently created the virtual machine, it is recommended that you wait 3 or 4 minutes before you begin this procedure.
To access and configure the virtual machine
1
By default, the instance does not have the DNS name configured. To configure the DNS name, find the DNS name field in the Networking section, and then click Configure.

2
By default, Azure provides the <region>.cloudapp.azure.com domain. Edit the options for the name based on your Public IP configuration, and then click Save.
3
Open an SSH session to the Public IP or DNS name.
4
In the SSH session, provide the credentials from Creating the virtual machine.
5
After you log in, verify the filesystem is operational for I/O using the system --show command. Check if "System State," is in "Operational Mode".
 
6
If the system is in Manual Intervention mode, use the following command to update the Azure Blob Storage account connection string:
object_direct --update_sentinel --cloud_container <containername> --cloud_provider AZURE
 
*
NOTE: The system prompts you for the connection string in secret.

To access the QoreStor UI, use the public IP assigned in the section Creating the virtual machine. The URL for accessing QoreStor UI would be https://<public_ip_of_virutal_machine>:5233.

 

Port usage

QoreStor uses certain ports for the services mentioned in the following table. The table also mentions the recommended network group settings (NSG) in Azure for each of the ports. Please refer to the next section for instructions on how to change the default/recommended NSG settings.

SSH

22

TCP

SSH uses port 22. We recommend keeping this port open to enable secure connections within and from outside QoreStor.

22: ENABLE

UI

5233

TCP

QoreStor uses 5233 for HTTPS connections (and not 443). Since this connection is secure, the port remains open in default NSG settings for all incoming traffic.

5233: ENABLE

Object (S3)
 
9001-9005
 
TCP

Object container uses port range 9001-9005 for data transfer. By default, NSG disables these ports. However, to use the Object container, enable the ports in NSG.

9001-9005: DISABLE
Secure Connect
9443
ANY

Port used by secure connect. Secure connect is enabled by default and we recommend keeping this port open in NSG settings.
9443: ENABLE

Configuring Azure Network Security Group settings

The settings for enabling or disabling the Network Security Group (NSG) settings are available in Azure using the following instructions.

To configure Azure Network Security Group settings
1
In the Azure console, find “Services” and click Network Security Groups.
2
Click the NSG name you want to modify. This is the same NSG that is deployed with the Azure Marketplace image of QoreStor.
*
NOTE: Any modification to this NSG will change the default settings recommended by QoreStor.
3
After you click the NSG name, a settings page like the one in the following image shows where you can modify the network settings.

When opening an additional port, to add inbound rules for that specific port, click Inbound security rules on the left side, and then click the Add tab on the top side of the page.
The following dialog opens.

5
On this dialog, you can add rules that open other ports. For example, if an Object container is enabled, then the corresponding ports as per the table in the earlier section – need to be open. In that case, complete the following options:
Table 5: Add inbound security rule options
Option
Description

Source

Select an IP or an Azure NSG. If the port can be used from any external interface, select Any.

Source port ranges

Select a port range on the specified source. To select any range, select *.

Destination

Leave as the default selection, Any.

Service

Leave as the default selection, Custom.

Destination port ranges

(Required) Enter 9001-9005 for this port.

Protocol

Select TCP.

Action

Select Allow.

Priority

Select an appropriate priority.

The rules are executed by priority, with the lowest number representing the highest priority. When selecting priorities, leave spaces between the numbers so that you can insert new priorities later.

Name

Enter an appropriate name for this rule; for example, ObjectServer_9000, which highlights the port number and the functionality.

Add a description as needed.

6
Click Add.
You can add rules as needed for corresponding functionality. For enabling multiple ports, NSG allows port ranges and comma-separated lists of ports so that multiple ports can be enabled as part of one rule. However, the Marketplace offer configuration does not allow for ranges or comma-separated ports, so a Marketplace image’s NSG template might mention each port number as a separate rule in such cases.
