ESXi Embedded Host Client

Posted by jpluimers on 2019/07/15

This version of the ESXi Embedded Host Client is written purely in HTML and JavaScript, and is served directly from your ESXi host and should perform much better than any of the existing solutions.

Installing went smooth:

# esxcli software vib install -v https://download3.vmware.com/software/vmw-tools/esxui/esxui-signed-6360286.vib -f
Installation Result

Determining the ESXi installation type (2014558) | VMware KB

Posted by jpluimers on 2019/05/31

Via [WayBackDetermining the ESXi installation type (2014558) | VMware KB

# esxcfg-info -e
boot type: visor-usb

That’s on my X10SRH-CF system which runs from USB.

Values you can get:

  • visor-pxe indicates a PXE deployment
  • visor-thin indicates an installable deployment
  • visor-usb indicates an embedded deployment

If your installation is visor-thin based (running from hard-disk), then you can convert it to visor-usb; the steps are at [WayBackvisor-thin & vsantraces – Hypervisor.fr (in French, but Google Translate is quite OK). It skips a few of the steps mentioned in [WayBack] How To Backup & Restore Free ESXi Host Configuration | virtuallyGhetto, so for saving your current config it’s best to follow these steps:

  1. Shutdown or suspend all VMs
  2. vim-cmd hostsvc/firmware/sync_config
  3. vim-cmd hostsvc/firmware/backup_config
  4. Copy the generated backup from /scratch/downloads (a UUID directory under it)to a safe location
  5. vim-cmd hostsvc/maintenance_mode_enter
  6. shutdown
  7. Install the same ESXi version on a USB disk
  8. Boot from the USB disk
  9. copy the backup to /tmp/configBundle.tgz
  10. vim-cmd hostsvc/firmware/restore_config /tmp/configBundle.tgz
  11. reboot

Some wizardry: vmkfstools | virtualhobbit

Posted by jpluimers on 2019/05/24

Some wizardry: [WayBackvmkfstools | virtualhobbit.

This includes:

  • finding which VMFS partitions are there the hard way
  • initialising partitions from known good data
  • vmkfstools -V (yes, capital V is for VMFS rescan, as lowercase v is for verbose)

Found after reading [WayBackDatastore not mounted after reboot of ESXi5.5 |VMware Communities

Then found this:

That solved my problem!

# esxcfg-volume --list
Scanning for VMFS-3/VMFS-5 host activity (512 bytes/HB, 2048 HBs).
VMFS UUID/label: 532cd010-6e8c01d1-45be-001f29022aed/Raid6SSD
Can mount: Yes
Can resignature: Yes
Extent name: naa.600605b00aa054a0ff000021022683ae:1 range: 0 - 1830143 (MB)
# esxcfg-volume --mount 532cd010-6e8c01d1-45be-001f29022aed
Mounting volume volume 532cd010-6e8c01d1-45be-001f29022aed

And there it was:

# df -h
Filesystem   Size   Used Available Use% Mounted on
...
VMFS-5       1.7T   1.6T    169.6G  91% /vmfs/volumes/Raid6SSD
...

Note you can mount non-persistent (--mount) or persistent (--persistent-mount) by both UUID and label, so there are four choices for mounting:

esxcfg-volume --mount UUID
esxcfg-volume --mount label
esxcfg-volume --persistent-mount UUID
esxcfg-volume --persistent-mount label

VMFS metadata files

Posted by jpluimers on 2019/05/09

For my own ference:

disk space under VMFS-3 is organized according to four resource types. They are : blocks, sub-blocks, pointer blocks, and file descriptors. Resources are grouped into clusters, which form cluster groups. Every resource type is administered by one or a number of system files. Lets have a look at what those abbreviated file names stand for:

  • fbb.sf = file block bitmap.sf
  • fdc.sf = file descriptor cluster.sf
  • pbc.sf = pointer block cluster.sf
  • sbc.sf = sub-block cluster.sf
  • vh.sf = volume header.sfs
  • dd.sf = scsi device description.sf

The VMFS-5 uses one more system file:

  • pb2.sf = pointer block 2.sf
