    For Dedicated Servers with Adaptec Raid Controller

    In this article you will learn how to monitor and rebuild your hardware raid if you Linux Server have an Adaptec Raid controller.

    With the software arcconf64 you have the possibility to control the Raid Controller of your server. For example, you can read information and rebuild a hardware raid if necessary. arcconf64 is installed on the server by default.

    Step 1

    Log in via SSH on your Linux Server and become root.

    Step 2

    Read information about your server with the command arcconf64 getconfig 1. Here is an example:

    Display the server events with the command arcconf64 getlogs event. An example looks something like this:

    Use the getlogs 1 device command to display events for the hard disk.

    step 3

    Please note: Before rebuilding a hardware raid, make sure that the Automatic Failover option is enabled. By default, this is the case. You can enable the option with the command arcconf64 failover 1 on.

    Enter the command arcconf64 rescan 1. In most cases the reconstruction of the raid starts automatically. The process is performed in the background and can take several minutes.

    Step 4

    If the recovery does not start automatically during rescan, delete the metadata of the hard disk with the following command: arcconf64 TASK START 1 DEVICE 0 2 CLEAR, where 0 stands for the controller channel, 2 for the hard disk port.

    Step 5

    Mount the replaced hard disk as a hotspare with the following command: arcconf64 SETSTATE 1 DEVICE 0 1 HSP LOGICALDRIVE 1 Reconstruction now starts automatically.
