Automating firmware updates on multiple HP servers involves connecting to the servers, checking for updates, and applying them. Here’s a simplified Python script using Paramiko for SSH connections:

import paramiko

def update_firmware(server_ip, username, password, firmware_path):
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(server_ip, username=username, password=password)

    # Upload firmware file
    sftp = ssh.open_sftp()
    sftp.put(firmware_path, '/tmp/firmware_update.bin')
    sftp.close()

    # Execute firmware update command
    stdin, stdout, stderr = ssh.exec_command('hp-firmware-update /tmp/firmware_update.bin')
    print(stdout.read().decode())
    print(stderr.read().decode())

    ssh.close()

servers = [
    {'ip': '192.168.1.1', 'username': 'admin', 'password': 'password'},
    {'ip': '192.168.1.2', 'username': 'admin', 'password': 'password'},
]

firmware_path = 'path/to/firmware_update.bin'

for server in servers:
    update_firmware(server['ip'], server['username'], server['password'], firmware_path)
