exception spicerack.ipmi.IpmiError[source]¶

Bases: SpicerackError

Custom exception class for errors of the Ipmi class.

class spicerack.ipmi.Ipmi(target: str, password: str, dry_run: bool = True) → None[source]¶

Bases: object

Class to manage remote IPMI via ipmitool.

Initialize the instance.

Parameters:

target (str) -- the management console FQDN or IP to target.
password (str) -- the password to use to connect via IPMI.
dry_run (bool, default: True) -- whether this is a DRY-RUN.

check_bootparams() → None[source]¶

Check if the BIOS boot parameters are back to normal values.

Raises:: spicerack.ipmi.IpmiCheckError -- if the BIOS boot parameters are incorrect.
Return type:: None

check_connection() → None[source]¶

Ensure that remote IPMI is working for the management console.

Raises:: spicerack.ipmi.IpmiError -- if unable to connect or execute a test command.
Return type:: None

command(command_parts: list[str], is_safe: bool = False, hide_parts: tuple = ()) → str[source]¶

Run an ipmitool command for a remote management console and return its output.

Parameters:

command_parts (list[str]) -- a list of str with the IPMI command components to execute.
is_safe (bool, default: False) -- if this is a safe command to run also in DRY RUN mode.
hide_parts (tuple, default: ()) -- tuple with indexes of the command_parts list that should be redacted in logs and outputs because contain sensitive data. For example setting it to (2, 4) would replace in logs and outputs the 3rd and 5th element of the command_parts list.

Raises:

spicerack.ipmi.IpmiError -- on failure.

Return type:

str

force_pxe() → None[source]¶

Force PXE for the next boot and verify that the setting was applied.
