Diagnostics allows checking server status, adding information to DCImanager, and preparing a server for a new client.
Server requirements for diagnostics
The server must have at least 4 GB RAM.
The server must be in the same L2 network segment as the location server. DHCP, TFTP and HTTP traffic must be allowed in this segment.
Before you start
- On the required server configure the network boot function with iPXE or PXE.
- We recommend configuring a connection between the server being diagnosed and the BMC (Intel AMT) or PDU. If the connection is not configured, you must manually reboot the server to start the diagnostics.
- Install the diagnostics templates on the locations. Learn more in Adding a location.
- Go to Servers → → Run diagnostics.
- Select the Diagnostics template:
- Diag6 — a recommended template for diagonstics.
- Select Server boot mode. If the server supports only one of the network boot modes, select a required one: PXE or iPXE. If both variants are supported, we recommend that you use the one set by the operation template per default.
Enable the option Configure BMC and select the Pool for allocating IP to BMC if needed.
- The pool can be selected if no connection to BMC is configured.
- If you select this option, connection to the BMC will be added, an IP address will be allocated from the pool, and the password of the user which credentials are used for login will be changed. Other BMC users will be disabled.
- To allocate an IP address, a physical network must be created at the location.
Enable the option Clear SSD and HDD disks during diagnostics if needed and select the method.
Disks will be cleared in any case if the macro $CLEAR_HDD or $FULL_HDD_CLEAR with the value "YES" is added to the diagnostic template. See Template macros for more details.
- Run diagnostics. You can see its status in the list of servers. When the process is completed, DCImanager will define the server configuration.
- If the server is not connected to a PDU, BMC or Intel AMT, reboot the server manually.
Hard drives connected to the RAID-controller will be defined during diagnostic only if they are grouped into the RAID.
You can find information collected during the diagnostics on the server page. To do this, go to Servers → menu → Server parameters → Components.

The diagnostics operation will end with an error if problems in any the following are found:
- SSD or HDD disks;
- BMC configuration or connection;
- hardware performance test progress;
- transfer of data collected by the diagnostics module to DCImanager server.
If the server diagnostics operations ends with an error, customer will not be able to order that server through the billing system.
Information about errors found during the diagnostics is displayed in a popup window in DCImanager interface. To view the errors, go to Servers → select the server → Details in Status column.
