Just start the Windows with safe modeor with recover disk Jail. Monitor Support Support Team. Author Commented: Thanks for your suggestion but I don't want to have to have to create virtual machines and run check disk in them as this will not be an accurate indication of disk issues anyway because you have the NTFS file system sat on top of the VMFS file system, and therefore two levels of journaling will mask any disk issues.

There must be a way to do something similar to 'fsck -t vmfs' in ESXi?!?! This one is on us! I couldn't find a disk check utility on the unsupported command line interface but appreciate if it is to be anywhere it will be here.

In the process and screenshots below, I will show you the steps I took to wipe the disk and configure it as a new VMFS datastore. You should see Storage show up above Networkingand below the Virtual Machines node, as in the screenshot below.

Select the Devices tab, to view a list of the physical storage devices installed in your system. Next, I selected the secondary disk the Crucial CTwhich took me to the device details screen for that specific disk. From the Actions drop-down box, choose the Clear Partition Table option. Now the disk has been wiped of its partition table structure, and you can provision it as a new VMFS datastore. On the disk detail screen, click the New Datastore button.

Give the datastore a new name. If you navigate back to the Storage node under the Navigator, on the left-hand side, you should now see the new VMFS datastore show up.

Thread starter Zarathustra[H] Start date Oct 4, Zarathustra[H] Fully [H]. Joined Oct 29, Messages 30, Hey all, Had an odd issue on my ESXi 5. I had 4 guests running Ubuntu Suddenly performance became terrible.

The client became mostly unresponsive, but would respond in fits and starts. At this point I had lost the ability to control the server via the Vsphere client and decided to reboot the server by either plugging in a keyboard locally and forcing a restart or just cutting power to it, and starting it back up again.

When the server started back up again, everything worked like normal again. There were no signs of the drive read issues I had had prior to the reboot.

All of my guests, except my Vista guest, booted back up normally again.Andreas Lesslhumer Since ESXi 5.

Please note, that the tool can only identify problems, as it runs in a read-only mode. So it does not help you to fix detected errors. First, you need to know the path to the partition naa. The tool can only find errors — but not fix them. If there is activity on the datastore you try to scan with VOMA, you will see the following output:.

Of course, you will need to format the LUN first. It is very slow and has other issues. In addition, Windows has very low availability due to the need for frequent patching. Finally, you generally want any storage device to have dual controllers in it and to have very fast failover between controllers.

A Windows Server is a single controller, and it will be down for many minutes if it reboots. Replicate your data and replace your array. An NTFS chkdisk will only be so effective. Because, as you said, it's sitting on top of VMFS. Whenever you suspect a bad block on disk in a production environment, it's always better to replace first ask questions later. Is there a way to tell which drive in the array has the bad block?

Is the hardware under any type of warranty? If so, you can probably get it replaced on that error by talking to a support person. I've done it - as far as seeing which one is bad, you will need to go into the RAID controller software. Scott does make a point. Can you not see from the health status in vCenter which disk? You still may need the OMSA to rebuild your array and it's nice to have available. Yeah, Jaguar nailed it. You should, at minimum, be able to see the state of your storage in vCenter.

At that point you can identify the drive. Having OMSA on your host just makes it easier to perform some of your functions, like storage configurations and changes, without having to reboot and go through the bios to get to it. No Vcenter all I have is the free stuff.

I can see some information listed. It actually shows that there is no problem with the system Oh, looks like that is it Turns out that if I had just looked at the event log closer I would have noticed that the drive that the event refered to was pointing to my ISCSI, which was offline To continue this discussion, please ask a new question.
