What should I do if the server KVM console does not respond to actions taken via the management console?What should I do if the server KVM console does not respond to actions taken via the management console?

Restart the BMC:

1. In the management console, select BareMetal and the relevant server.
2. In the left-hand menu, select KVM console.
3. In the console window, click Reset BMC.

If restarting the BMC did not help, contact support.

What should I do if there is a disk failure on the server?What should I do if there is a disk failure on the server?

If there is a disk failure on the server, contact support and request a replacement. If the defective disk was a part of a RAID array, you need to add the new disk to this array.

For more information, see the disk replacement guide.

What is a gigabit per second (Gbps)?What is a gigabit per second (Gbps)?

Gigabit per second (Gbps) is a unit of measurement for data transmission speed. It describes the throughput of a network interface and represents the number of gigabits of data that can be transmitted through the network interface in one second.

What is a gigabyte per second (GB/s)?What is a gigabyte per second (GB/s)?

Gigabyte per second (GB/s) is a unit of measurement for data transmission speed. It represents the number of gigabytes of data that can be transmitted in one second. Typically, one gigabyte (GB/s) equals eight gigabits (Gbps).

How to calculate the amount of data transmitted over a server's network connection?How to calculate the amount of data transmitted over a server's network connection?

To calculate this, you can use this formula:

Amount of data transmitted per day = number of seconds in a day * speed (in GB/s)

NetworkNetwork

What should I check in case of network issues?What should I check in case of network issues?

If your BareMetal server is experiencing network issues, check the following:

1. Make sure the network interfaces have IP addresses assigned:

   ip address
   

   If using DHCP IP address assignment, make sure DHCP is enabled. For details on setting up DHCP, see DHCP in a Yandex BareMetal network.

2. Check the route table:

   ip route
   

   Private subnets must be routed to the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 networks. For more information, see Server routing table.

3. Check the default gateway availability:

   ping <gateway_address>
   

4. Check the MAC address limit: make sure the number of MAC addresses on the server does not exceed it. For more information, see MAC addresses.

If DHCP is disabled, check the OS configuration files to make sure the static IP addresses and routes are configured correctly.

What information should I submit to support when reporting network issues?What information should I submit to support when reporting network issues?

Before submitting a request to support, gather the following diagnostic information:

1. Command output:

   ip address
   

2. Command output:

   ip route
   

3. Contents of the configuration files located in the /etc/netplan/ directory (if any).

4. If you have issues with access to specific resources, provide this command’s output:

   mtr -n <resource_address>
