This looks like a former VMFS-3 volume. The block size impacts the maximum capacity of the datastore under the legacy VMFS-3 format. But beyond that and with vSphere 5.5, you have to use the Web client to do anything with larger VMs and VMDKs. Use the vSphere Web Client to create VMDKs larger than 4 TB, or to extend an existing VMDK beyond 4 TB.

Resolved. When looking at the datastore through the vSphere Web Interface (my fault, I still prefer the old client) it correctly shows the 62TB max size limit. Potentially a hardcoded value in the old GUI given it's now deprecated.

No, you cannot have multiple vCenter servers managing the same hosts at the same time. In KB1024051 the supported HA options for vCenter are outlined. New in version 6.0 is the option to use Microsoft Clustering for the Windows version of vCenter which probably provides the best availability, but also introduces the highest possible complexity.

the solution to fix this is to sync all parties (ESXi hosts, vcenter, VRM Appliance) with ntp servers. Once this done - the error is gone.

As ewwhite and GregL already mentioned, install the OpenMange VIB within your ESXi. This also works great on the ESXi Free, but you need do do it at the commandline. For automated monitoring, we use check_openmanage - a great nagios/icinga/etc-plugin which is talking directly to the OpenMange-Daemon running on your ESXi. It also works great with OpenManage ...

AFAIK you cannot make ESXi to wait for a VM to start before mounting the datastores. I may be wrong though. The datastores are mounted way before any VM can boot up. In general iSCSI connects right away if you do a rescan on the iSCSI sw adapter after your storage VM boots up (and rescan it works way better than NFS, where if it gets disconnected/inactive ...

We finally found the reason. It is related to Fortigate ICMP session timeout problem. When VPN is down, ICMP session is marked to go via interface directly rather than VPN tunnel. However, when VPN recovers, the session via path is not modified until live time becomes zero. If you keep pinging, the live time can never be zero.

That method should work, mostly the esxi host's are static once they are configured with an ip, interfaces, and management. If you are talking about backing up the configuration of VCenter then you can just export the database that it uses to run. Vcenter is where all of the vlans, host configurations are mostly stored.

No, that model didn't ship with an SD card slot. In terms of your actual problem do you mean HP P2000? if so which version and which connectivity option (i.e. FC, SAS etc.) The DL180 G6 shipped with a few disk controller options (P410, on-board etc.) but I'm pretty sure no standard configuration offered external SAS ports so we could do with knowing the ...

I have seen the same issue on Linux hosts. The solution was to deactivate Large Receive Offload (LRO) on the network driver (vmxnet) of the gateway machine. To quote the VMware KB: LRO reassembles incoming network packets into larger buffers and transfers the resulting larger but fewer packets to the network stack of the host or virtual machine. The ...

As far as I know, there's no way to pass a VMFS volume up to a guest, but I also can't see why you'd need to do it. Either way, you wouldn't be able to read it with anything other than the the SDK since it's a proprietary format. If you're looking to backup your VMs, you should really be looking at the APIs provided by vSphere and use a tool meant for the ...

One of my hosts showed the same "Lost connectivity" error. I googled and found this post. So I tried to backup the configuration with PowerCLI and vCLI as suggested. Backup came back with "Internal error". Called VMWare. The answer is that when the SD failed, you won't be able to backup your configuration because the backup command can only pull the ...

I would really, really urge you to not put your ESXi management interface on the Internet directly. Your only security control is then your password, which gives you full keys to the kingdom. I would suggest that you install a Unified Threat Manager (UTM) like pfsense or Untangle to be your router with a public IP address. Your network would look like this: ...

Your hosting provider (Hetzner, at a guess?) is correct. You will need to assign the single static IP address to your VMware server's VMK interface. This will allow you to connect to the server via the VMware console and create VMs. Your hosting provider should be able to route your /29 subnet to the server's MAC address. You will also have a single ...

ESXi doesn't support the OpenStack API directly. There's VMware Integrated OpenStack (VIO)... although I don't think it's supported to use other hypervisors with this. If you want to use vSphere as a backend for OpenStack without VIO, this is fortunately documented here but it looks like this works via vCenter only. If you can't use vCenter because you ...

How would one achieve this functionality? vSwitches are just that, a switch, and nothing else, if you had a physical switch how would you expect it to do this? You wouldn't, you'd probably do it via round-robin DNS or an external load-balancer. Does the solution lie within the VM (pfsense) or at the ESXI networking level? How about within the ...

It is my understanding that ESXI snapshot removal can (and usually does) take a long time. Before the snapshot can be removed the changes from the old snapshot need to be written to the next snapshot in order. I was taught to always delete snapshots from oldest to most recent to help this process run as quickly and efficiently as possible. Naturally, the ...

I was having the same problem last night. My configuration is using the same NAS for both ESXi. So I connected to the secondary ESXi browse the datastore and found the folder of the VMs. Then I located the .vmx file, right click on it and press "Add to inventory". So I got my VMs online again and tried to hard restart the ESXi. I wasn't able to connect on it ...

This happened quite a bit with some of our Windows VMs (2008 R2 and 2012). However, the problem only shows itself after a number of reboots - the actual number seems rather nondeterministic (betwwen 2 and 20). After setting the ArpRetryCount to 0 as recommended in KB article 1028373 the problem did not occur anymore. To work around this issue, turn off ...

I think i found a clue . the two cards were on separate vswitch and i tested also the card in the same vswitch and assigning a vmnic to each portgroup. It looks like if i want to force read on vmnic0 and write on vmnic1 to maximize bandwidth something is slowing it down. Now if i put all vmnic on the same vswitch (separate port group) and default ...

Check your P410 raid controller write cache. Vmware rely on hardware for caching. You may need to add a BBU (Battery Backed Unit) on your controler to handle write back safely in case of power outtage.

you should look for the wbem protocol to monitor your esxi look at this plugin This script is a Nagios plugin to monitor the hardware of ESX and ESXi servers. It can also be used as standalone script to check the hardware - Nagios isn't necessary to run it. The plugin is written in python, so you need to have python installed usage : ...

Cobbler is the way to go, because it takes care of everything from dynamic DNS, to dhcp. Using snippets you can further customize your installations. Using cobbler you can provision all three of them. ESXi: http://www.nerdknobs.net/using-cobbler-to-rapidly-deploy-esxi-with-zero-touch-configuration-2/ Ubuntu: ...

Burn the iso content on a dvd, or else you will need to make the USB key bootable.

This has been resolved. The core issue was that we had our hosting provider was running VMWare snapshots as a backup mechanism. These snapshots were causing the VM to temporarily go into a period of stasis, I believe the technical term is that the VM quiesces. Once these snapshots were disabled, we no longer had any issues.
