FILEZILLA KEEPS DISCONNECTING DOWNLOAD
Connect to the host with WinSCP, Filezilla, and so forth, and download the file.Return looks like: rwx- 1 root root 32.8M Aug 15 05:10 /var/core/hostd-worker-zdump.001 With vSphere 6.5 and later: # services.sh restart and tail -f /var/log/jumpstart-stdout.log.If no LACP, restart all management services on the host with one of these commands:.
Check for LACP (Do not restart all services if LACP is being used as this can cause other issues): # localcli network vswitch dvs vmware lacp config get.If the commands worked, but the host is still not connected, try restarting all management services:.Try restarting ' hostd' and ' vpxa': /etc/init.d/hostd restart & /etc/init.d/vpxa restart.Check the status of ' hostd' and ' vpxa': /etc/init.d/hostd status & /etc/init.d/vpxa status.If the disconnected host does not seem to have an issue with services (pings fine, web client to host works, DCUI looks fine, and so forth), you can try right-clicking the host in the vCenter's 'Navigator' under 'Hosts and Clusters' and selecting the options for connecting the host.If not, it may be unresponsive to diagnostic screen ("PSOD"), powered down (turn it on if possible), or have a networking issue. Check to see if you can ping the host.In the DCUI, press Alt + F11 to see if the host monitor indicates that an issue like hostd service stopped is showing.Try to open a vSphere web client to the host: a PuTTY session, or a Direct Connection User Interface ("DCUI" -open a console through IDRAC on Dell platform or BMC on Quanta). Inability to connect by PuTTY or vSphere to a host that is online (VMs are running), bad lag in the DCUI (or cannot even get to it), and inability to restart services or run other commands using command line, indicate lack of available host resources as described in the Detailed Description.Check if VMs known to be on the host (these are likely also showing as disconnected in the vCenter) are still running.If after following the troubleshooting steps below, the host is still not connecting to the vCenter properly or you have questions or need assistance, contact Dell EMC Technical Support, or your Authorized Service Representative to open a Service Request. See Detailed Description in the Notes field below for more information. Rebooting the host to get back memory that was not properly reclaimed by the host after use (a memory leak) is frequently the only way to recover the host's manageability and reconnect it to vCenter. In these cases, the host's storage is still fully functional within the VSAN datastore and its VMs usually continue running properly for a time. The result is a host that fails to respond to vCenter and is slow and difficult to access or manage in other ways. The vCenter cannot communicate with the host due to the lack of these services and general difficulty with a lagging host that does not have enough available resources to function properly.
An ESXi host shuts down resource-intensive services like hostd rather than take from what is allocated to running VMs, if they need it. While there can be other reasons (see Notes section below for links to additional articles), unresponsive host services can be caused by the host running out of available resources (usually memory).
This situation is due to certain services on the host that are not running properly.
