Reboot the ESX host as possible while on VM snapshots exist?
Can you safely do a reboot of a host ESX VM there was on this host which are off (of course), but have a snapshot exists at this time?
Because we restart some ESX host but you also have to install some Windows updates on the virtual machine on these hosts. Normally, we take a snapshot of the WM, install updates, restart, check if everything is working fine, and then remove the snapshot. But after a reboot the ESX host we also check if the VM have started and are working very well. In this case, it would cost me 2 restart and check for WM
When I could do the snapshots, installation of updates, power off the virtual machine, reboot the ESX host, turn on the virtual machine, all check and then delete the snapshots, it saves me time. Only thing I don't know and can't find is so it record to make a snapshot is by restarting the EX host and if the snapshot can be deleted after reboot normally.
Welcome to the community,
don't worry, a restart of the host is quite VMs, regardless of whether they are active or not snapshots.

Here's what happens when you try to turn it on one of my virtual machines (see also accessories):

This circumstance may be linked to a sata cable issue, with the possibility of temporary loss of connectivity, which could result in data loss/corruption, I realize. It is a laboratory box. Especially say that the 2 VMDK he complains (trying to light) is both on the grounds of a single physical disk. Data, read and written to the speaker, since the problem are very good (which indicates the wiring problem was resolved, and the VMFS5 file system seems to be in good health).
No photos. No related clones. Just a 2012 Windows Server based VM, with several drive letters in, with those underlying files VMDK residing on different stores of data VMFS5. Implemented end (these drives aren't really so huge), but far from running out of physical space for the data either. Everything is working great for months, until today, trying to it turns on again.
You are looking for:
"Failure error disk beginning module lit" results in this article:

Then upwards, of a variety of other items:
but alas, none of them seem to relate directly, or exactly. My vmware.log file is attached below, as well as some screenshots of to show the structure of the unity of this virtual machine. Hoping that this post proves fruitful, if anyone has had a similar situation. The data at stake here are (mostly) redundant, but I would rather understand my way of it, in the case where it happens to me again, or can help others. Many preferred rather than give up, reformat the VMFS and start again.
Thank you!
Good news, the best result I could hope. No data is lost. No corruption of the VMFS or NTFS don't drive in the virtual machine. Nice! Saved me a few terabytes of data restoration and learned a little more on file system of troubleshooting along the way.
It took a technician of VMware Service excellent, attentive, methodical remote 2 hours in a WebEx previously to resolve problems with these 2 files vmdk manually, because he found that there is a lock on them. I opened a request of Service (SR) # with VMware by following the instructions here:
VMware KB: Cannot access certain files on a VMFS datastore
To resolve this problem, apply for support from VMware Support and note this ID (1012036) Knowledge Base article in the description of the problem. For more information on the filing of a request for support, see How to submit a support request.
I'll cover this saga and the exact process for collecting and downloading of newspapers, through to my TinkerTry.com, including the ride video. I even captured much of the technical work that has been done. That said, it is true that little of the magic that was made to resurrect the metadata will remain a mystery, given that this piece is VMware.
I'm ok with a bit of black box, considering how I'm happy that I got all my data, and time savings that the quick recovery represented.

Yep, take a look at FindByDatastorePath which allows you to search by path of the data store and returns a VM MOR

Restart VM after you restart the ESX host
Hi all
I am using VSphere Enterprise.
Here my little question, makes VMs always restart after back us running or stopping of the esx host?
In esx 3.5, when I reboot an esx host, all the virtual machines in this host are still alive (without restarting).
Pls advice
Thank you
The only way, a virtual machine can rest running when it is running on ESX server is restarted is that if FT is activated - in this case, the connections will be seamless switch to the virtual machine "shadow". This is a feature of vSphere, so I don't see how you did not the VMs restart on your ESX 3.5 - even with VMware HA environment, there will be a short break because the VMs will be will be running on the other nodes in the cluster.

Grant Web access to the only vm on the esx host
I have read the Administrator's guide and spent a few hours online on this subject and other types of users doing the same thing...
I have 2.5 VC and ESX 3.5 by running very well. I want to give web access to a virtual machine #1 running on ESX #1 host in this species, using the URL for the console "generate".
I went VC and granted permission to the user of the Virtual Machine to the particular user I want to access the virtual machine. I granted this permission to the esx host and the virtual machine. When the user attempts to connect (this is a domain account) they get the connection failed due to bad user name or password. It seems that the only account that can connect to web access is the root on this esx host account. I am at a loss here, because I also tried to set this user as an administrator and so on. The only account that can connect to web access, is that the account root localhost.
What I'm missing here?
The user attempts to access Web Access to the ESX Server? Which is what I think they do because without a third party tool they will be able to authenticate users who are in the service console, including the roots. If they try to access Web App of VC by pointing a browser VC while they should AD credentials to access their virtual computer.
Another thing to remember is that permissions in VC only apply when you log in to VC

I had to reboot an ESX host, so I moved the virtual machines out of it. Put in maintenance mode and click on restart. However, after you restart the host went offline and changed his status does not. I was quite puzzled and checked the papers and of course I got [not restarted] stop the ESX host.
My question is, do I I turn back on the ESX host remotely? Because I don't have access to the physical box itself.
You have access to the DRAC or equivalent of IBM or the ILO. Otherwise, if the host is really turned off, the only option is to have someone physically in front of the console

How to report the current time on the ESX host in to a csv file with the following
Hello guys
I have the script next where I make the required details except the current time on the ESX host. Anyone can guide me please.
{foreach ($esx to $vmhosts) $hostVC = $vcenter $hostCluster = $esx. Parent.Name $hostHost = $esx. Name $ntp = $esx | Get-VMHostNtpServer $hostNTP = "$ntp". } I want to integrate the following for loop of the above for loop and ge the output in a single table.
foreach ($esxcli in get-vmhost | get-esxcli) {"" |} {Select @{n = "Time"; e = {$esxcli.system.time.get ()}}, @{n = "hostname"; e = {$esxcli.system.hostname.get (.hostname)}}}
Add-Content - Path '$hostVC, $hostCluster, $hostHost, $hostNTP, $hostTime' $hostInvFile - $ hostTime is where I want to get my host right now.
I'm vcenter, esx name, name of the cluster, host of the ntp server address, but I need the host thus present.
Thanks in advance.
Thank you
vKar
Try changing the line where the script retrieves the VMHost to this
$vmhosts = get-VMHost-State connected. Name sort
This way the script will be only to ESXi nodes that are "connected".
Pick up time for those defective does not much sense in all cases

Adding data to the ESX host store
Hi all
We are automating the process of adding data to the esx host store. We have all the necessary inputs as a host, Cluster, data center, data store name, store (VMFS) Pat data.
Do we have the cmdlets to get the result? What is the data store should be added after the configuration of the network?
We need confirm that the data store must be there in vcenter/Cluster?
Please help explain the process.

Check if the esx host is in maintenance mode
HelloI need to know if there is a api in java vi which can let us know if any of the esx host is currently in maintenance mode?
I know there is a way to discover this through the same monitoring using event Manager, I need to know is an api live which can let us know if the esx host is in maintaince at that precise moment?
Thank you and best regards,
Rachid chollet.
Hi rachid,.
I guess that the following property is what you are looking for: HostSystem.runtime.inMaintenanceMode
But watch out for the docs for the property when it reads it: it is not set during the entry phase of maintenance mode.
