Issue

The BMC UI on H610S and H615C (Quanta platform) nodes does not provide an option to add or change NTP servers. NTP servers can be configured using ipmitool raw commands directly against the BMC.

Note: Verified on BMC firmware 4.01 (Quanta).

Solution

  1. Verify the current NTP configuration:
    ipmitool -I lanplus -H <BMC_IP> -U root -P <password> raw 0x32 0xa7
    The response is a 257-byte blob: bytes 1–128 contain NTP server 1 and bytes 129–256 contain NTP server 2 (both null-padded ASCII strings).
  2. Set NTP server 1 — slot 0x01, server name padded to 128 bytes:
    SERVER="ntp.example.com"
    python3 -c "
    s=b'$SERVER'
    pad = s + b'\x00' * (128 - len(s))
    print(' '.join(f'0x{b:02x}' for b in b'\x01' + pad))
    " | xargs ipmitool -I lanplus -H <BMC_IP> -U root -P <password> raw 0x32 0xa8
  3. Repeat for NTP server 2, replacing \x01 with \x02 in the python command.
  4. Verify the change:
    ipmitool -I lanplus -H <BMC_IP> -U root -P <password> raw 0x32 0xa7
