SuperMicro iKVM and IPMI: not able to initiate “Virtual Media” -> “Virtual Storage”

Posted by jpluimers on 2021/05/24

I had something odd on one SuperMicro systeem:

The “Virtual Storage” menu item under “Virtual Media” was marked grey (gray?) as being unavailable.

Despite that, no disk image was shown mounted according to the web interface at menu path “Virtual Media” -> “CD-ROM Image“:

Port settings were good though as seen in menu path “Configuration” -> “Port“:

Even nmap did not show significant differences between the various systems (partial dump here; full dump below)

Discovered open port 443/tcp on
Discovered open port 5900/tcp on
Discovered open port 80/tcp on
Discovered open port 22/tcp on
Discovered open port 5985/tcp on
Discovered open port 623/tcp on

I use alias alias nmap-fingerprint_host_all-ports-even-if-ping-fails='sudo nmap -O -v -A -p- -Pn' here as it usually gives best results for port scans on a single machine.

“Secret” setting

The secret is in a different menu entry under menu path “Maintenance” -> “IKVM reset“:

After pressing the Reset button, then restarting the iKVM client, “Virtual Media” -> “Virtual Storage” is nog grey any more, and just works:

LGA 2011 – remove and insert a CPU

Posted by jpluimers on 2021/05/21

I while ago I needed to upgrade a processor in a LGA 2011  socket

If you know what the icons mean they are simple.

  • The (1) lock on the top left means that lever (with the triangle bend in it) needs to be done first when locking
  • The (1) unlock on the bottom right means that lever (with the rounded end) needs to be done first when unlocking

When all your SuperMicro X9/X10/X11 IPMI sensors show N/A: the system is in a BIOS or boot selection screen

Posted by jpluimers on 2021/05/17

I have seen this happen on various Supermicro X9/X10/X11 systems including X9SRi-F/X9SRi-3F/X10SRH-CF/X11SPM-F boards:


I found this via:

  • [WayBack] IPMI no sensor readings and already reset | iXsystems Community
  • [WayBack] Supermicro X10 and X11 motherboard FAQ | iXsystems Community

    All the sensors read N/A 

    First of all, make sure you’re not in the BIOS setup menu. IPMI monitoring of sensors isn’t available there.

    If that is not the case, the procedures listed under “The CPU/PCH temperatures read N/A” may help.

    The CPU/PCH temperatures read N/A

    While the exact cause is unknown, the BMC may enter a faulty state, requiring a reset.

    The following options were recommended to me by Supermicro:

    • Start by power cycling the IPMI. This can be done from the web interface.
    • If that doesn’t work, reset it to factory defaults via the web interface and power cycle it (it will not work until it is properly power cycled).

Connectors/cables for Serial Attached SCSI and SATA – Wikipedia

Posted by jpluimers on 2021/05/10

Since I always get confused with SAS and SATA connectors, some tables from Wikipedia:

  • Serial Attached SCSI Connectors- Wikipedia
    Codename Other names Ext./int. Pins No of devices / lanes Comment Image
    SFF-8086 Internal mini-SAS, internal mSAS Internal 26 4 This is a less common implementation of SFF-8087 than the 36-circuit version. The fewer positions is enabled by it not supporting sidebands. SFF 8086.jpg
    SFF-8087 Internal mini-SAS, internal mSAS, internal iSAS, internal iPass Internal 36 4 Unshielded 36-circuit implementation of SFF-8086. Molex iPass reduced width internal 4× connector, 12 Gbit/s capability. SFF-8087 SMC.jpg
    SFF-8088 External mini-SAS, external mSAS, external iSAS, external iPass External 26 4 Shielded 26-circuit implementation of SFF-8086. Molex iPass reduced width external 4× connector, 12 Gbit/s capability. SFF 8088.jpg
    SFF-8470 InfiniBandCX4 connector, Molex LaneLink External 34 4 High-density external connector (also used as an internal connector). SFF 8470.jpg
    SFF-8482 Internal 29 2 lanes This form factor is designed for compatibility with SATA but can drive a SAS device. A SAS controller can control SATA drives, but a SATA controller cannot control SAS drives. SFF-8482 SAS Plug - Bokeh at f22.jpg
    SFF-8484 Internal 32 or 19 4 or 2 High-density internal connector, 2 and 4 lane versions are defined by the SFF standard. SFF-8484 straight connector.jpg
    SFF-8485 Defines SGPIO (extension of SFF 8484), a serial link protocol used usually for LED indicators.
    SFF-8613 (SFF-8643) Internal 36 4 or 8 with dual connector Mini-SAS HD (introduced with SAS 12 Gbit/s) SFF-8643 SMC.jpg
    SFF-8614 (SFF-8644) External 4 or 8 with dual connector Mini-SAS HD (introduced with SAS 12 Gbit/s) SFF-8644 cable.jpg
    Sideband connector Internal Often seen with 1× SFF-8643 or 1× SFF-8087 on the other end – internal fan-out for 4× SATA drives. Connects the controller to drives without backplane or to the (SATA) backplane and optionally, to the status LEDs. Sideband.jpg
