ESXi 6.5.0a hang after “balloonVMCI loaded successfully”

Posted by jpluimers on 2019/03/25

No Google results for “balloonVMCI loaded successfully”.

I had this when booting from a USB installation of ESXi 6.5.0.a.

It got resolved with ESXi 6.5.0 Update 1. Apparently the first version has issues booting on a SuperMicro-X10SRH-CF from a USB stick.

It’s a bit tricky to get the accompanying VMware-VMvisor-Installer-6.5.0.update01-5969303.x86_64.iso as the my VMware site is a bit broken (even if you have the license, it says you are not entitled), but luckily the ESXi 6.5 update 1 download page [Cache/Archive.is] has the hashes:

MD5SUM: 6d71ca1a8c12d73ca75952f411d16dc7
SHA1SUM: 5a38ae10162e0a1395b12ea31cba6342796f6383
SHA256SUM: f6e5000dff423c275b3ffbdfe08145f369d04b8c4ade5a413f2ef2a029a5e3ef

You also need a good USB stick. If it’s not good enough, you get errors like “Host Local Swap Location has not been enabled” during boot**.

Supermicro | Products | Motherboards | Xeon® Boards | X10SRH-CF

Posted by jpluimers on 2019/03/01

I still like this board: [WayBackSupermicro | Products | Motherboards | Xeon® Boards | X10SRH-CF.

It’s in my main virtualisation workhorse, uses little power, has loads of disk (SAS/SATA) ports, IPMI, two network connections and enough slots for memory and I/O to be extensible.

I use it for most of my software development even when on the road: VPN home over one of the fiber connections and it screams.

Some links, as SuperMicro tends to hide them behind POST requests:

That duh moment when you cannot read an SD card: it’s SDHC/SDXC in an SD card reader; Secure Digital – Wikipedia

Posted by jpluimers on 2019/02/18

That moment you facepalm yourself because you forgot that particular machine won’t read SD cards because they are too big for the SD card reader in it: SD goes up to 4 gigabyte, anything bigger (nowadays basically everything) requires SDXC or SDHC compatible readers.

Quotes from Wikipedia:

However, older host devices do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade.[11] Older Windows operating systems released before Windows 7 require patches or service packs to support access to SDHC cards.[12][13][14]

Older host devices generally do not support newer card formats, and even when they might support the bus interface used by the card,[6]there are several factors that arise:

  • A newer card may offer greater capacity than the host device can handle (over 4 GB for SDHC, over 32 GB for SDXC).
  • A newer card may use a file system the host device cannot navigate (FAT32 for SDHC, exFAT for SDXC)
  • Use of an SDIO card requires the host device be designed for the input/output functions the card provides.
  • The hardware interface of the card was changed starting with the version 2.0 (new high-speed bus clocks, redefinition of storage capacity bits) and SDHC family (Ultra-high speed (UHS) bus)
  • UHS-II has physically more pins but is backwards compatible to UHS-I and non-UHS for both slot and card.[27]
  • Some vendors produced SDSC cards above 1GB before the SDA had standardized a method of doing so.

2018 Hard Drive Reliability Stats by Manufacturer and Model

Posted by jpluimers on 2019/02/11

We look at the hard drive failure rates for the data drive models in operation in our data centers in 2018 (now totaling over 750 petabytes and 100,000 drives). In addition, we’ll see how the new hard drive models we added during the year did, including our 12 TB HGST and 14 TB Toshiba drives.

Since my brother has this motherboard: M4N78 PRO GREEN.

It does WOL, but doesn’t always wake up when powered down.
