I have several VM defined where the associated folder name does not match the VM name. Is there a way that I can rename the folder name to match the VM name. Also, is there a way that I can rename the VM to match the folder name?
Thanks in advance,

When I install vCLI 4.1 on my debian 6.0 stable machine, I get some unhappy message about the "version" and "UUID".
The following Perl modules were found on the system but may be too old to work with vSphere CLI:
version 0.78 or newer
UUID 0.03 or newer
It says the version and UUID is old.
How can I avoid this problem?
Thank you very much!!
In the course of testing a new vSphere 4.1 infrastructure, we lost connectivity to the SAN due to a power issue. iSCSI shared storage for all ESX servers in the cluster was cut off, taking down vCenter as well, which is installed in a VM. When we tried to log on to the individual ESX servers using the vSphere client to begin troubleshooting, we encountered an error that stated:
"the vSphere Client could not connect to <ipaddress_withheld>. A timeout occurred while loading the inventory."
The system uses the Nexus 1000v virtual distributed switch, and 2 Nexus 5010 physical switches. Each ESX server has two physical 10GbE nics attached to the Nexus 5010, as does the SAN. Both NICs on each ESX host are setup in on the 1000v virtual switch, where the vmkernal for each ESX host is connected as well. When the connectivity to the SAN was lost, we were still able to ping all of the ESX hosts, and were able to ping and SSH into the Nexus 1000v vDS.
After bringing the SAN back online, we were able to connect into vCenter normally, as well as connect into each individual host using the vSphere client.
Our plans are to eventually connect another management interface to the built-in 1Gb ports on each ESX server for "out of band" management, in case we have issues with connections through the Nexus physical or virtual switches.
Any ideas on why I am unable to connect to the ESX servers while the shared storage is down? Again, the vSphere client connects, but gets stuck at the "loading inventory" stage, then times out. This happens on all 4 hosts. We also tested again after the power failure by disconnecting the ports on which the SAN is connected to the Nexus 5010, and experienced the same symptoms.
Thanks for any help or suggestions

Good Morning,
I'm running a Windows 2008 Standard Virtual machine which has SQL 2005 installed, on VMWare ESX 4.0 (Update 2)
I need to extend one of the SQL drives as it's starting to run low on available disk space.
Therefore, I edited the size of the disk through VI client, and then logged onto the virtual machine, done a rescan of the disk. The new 40GB of disk space that I allocated was showing and I was able to extend my current disk into the new space.
The strange thing is that through computer management, it's showing the new disk size but hasn't updated the free space. Also from the 'My computer' view it shows the original size?
Has anyone seen this before?
Thanks
Hi Guys,
For one of my ESX 4.0 host I am not getting putty. There is no problem with firewall and all. when I am putting IP in putty console to connect the server, getting network connection error, how to resolve this?
Please help!!!
I was looking at creating some udev devices on rhel5.5 in a guest VM on ESXi 4.1 update 1 and was noticing when I run :
scsi_id -g -u -s /block/sdc
Nothing is coming back at all. I tried:
scsi_id -g -u -x -a -s /block/sdc
ID_VENDOR=VMware
ID_MODEL=Virtual_disk
ID_REVISION=1.0
ID_SERIAL=
ID_TYPE=disk
ID_BUS=scsi
But nothing else, and can't get a UUID at all. Has anybody been able to create a udev devices using a GUIDs? or etc? I want to create a persistant udev and raw device so that when I reboot the VM and if I change/add a device on 0:2 or whatever that the /dev/sd* names that are mapped to /raw/raw* devices don't get moved around automatically.
Thanks
Hi Guys,
I'm currently running ESX 4.0 (Update2) in an HA cluster consisting of 4 servers attached to a Netapp Storage appliance utilising NFS mount points.
The ESX Servers are running on HP DL580 G7, and originally had 128GB RAM per server.
At the weekend, I installed an additional 64GB per server (8 x 8GB dual rank sticks) however I'm now getting the following message from the console:
cpu0:0)NUMA: 837: Significant imbalance between NUMA nodes detected. Performance may be impacted.
I believe the reason for this is the HP server has 4 available memory banks, of which I have two consisting of 32GB, and the other two consisting of 64GB giving me 192Gb in total. The 32GB banks are made up of 4GB dual rank stick which came with the server.
Obviously, the imbalance is due to the fact that 2 CPU's are receiving less memory than the other two.
In an attempt to resolve the matter, I reallocated the RAM so that each bank had 48GB, however following this change the HP server failed to boot.
As far as I can make out, the message does not appear to be having any detrimental affect on the environment, and the easiest way to resolve the matter would be to replace the 4GB stick with 8GB stick to balance the memory banks?
Another change I have tried is to set the NUMA.REBALANCE advanced setting in VMware to disabled, again this did not clear the message.
Numa.RebalanceEnable and set to 0 to disable.
Has anyone ever come across this message before and managed to resolve it? As mentioned the HP server itself is recognising the full allocation of 192GB RAM, and so is VMware. From the VI client no error messages are showing, it's just purely from the console?
Any help would be greatly appreciated.
Thanks
Hello all, please help me with this.
I have a hp proliant 165 G7 server running with windows server 2008 R2. I decided to install ESXI 4.1 on it and it seems ok, i installed the vsphere client on another machine and the connection between client and ESXI host as succeed. But the problem is that the server do not boot from windows server 2008 anymore!! It boots from vmware Hypervisor and stops with the following screen:
"VMware ESXI 4.1.0 (VMKernel Release Build 348481)

When we setup our iSCSI adapter in ESX4 when enabling the iSCSI the long proper iSCSI name that is created we changed it to something shorter. The iSCSI didn't care. A new iSCSI appliance we've bought seems to only want the long auto generated name. Is there anyway to regenerate this? I've disabled the software iSCSI adapter, rebooted the host and when I renable the iSCSI software adapter even though the name box is blank it puts the short name we gave it back in.
Hi there,
I had a user complain about losing his RDP connection every now and then to a virtual machine I created for him. Quick ping check towards the machine shows that I get ping timeouts when pinging that particular virtual machine. I also pinged the host the virtual machcine was on, and there was no timeouts there. Mostly 1 ping timeouts, but i have noticed that sometimes its up to 8-10. Also checked the two cisco 2960G switches we have and no packet errors or dropped packets there. Not sure where to start looking for this issue. Anyone experiencing anything similar? Any logs to start looking for clues in?
The virtual machine is running Windows 2008 R2.
Any help is appreciated.
Hi All,
As we are planning to remove one of 3 hosts from cluster in order to add another super power host to our cluster. What caution should I take into consideration? what steps ? please
Thanks in advance
Regards,
Does anyone know how SQL 2008 licensing works with virtual machines.
For example I have purchased a 1 Processor license for SQL 2008 but say I wanted to run this as a VM but the host esxi server has 2 physical 6 core cpu's installed.
Is this possible or do i need to purchase 2 CPU licenses?
I have tried searching on the web but I keep finding conflicting answers.
Many Thanks

I have the problem, when i install the VMware Tools in a VM the memory utilisation goes up to 60%. When i deinstall the VMware Tools, the memory utilisation goes back to a normal level. My environment looks like this:
ESX 4.1.0 Build 502767 and ESX 4.1.0 Build 433742 (tried both versions)
Hardware: HP Proliant DL 585 G7
VM: Windows 2008 R2 SP1, 4 vCPU 8GB Memory
Does anyone have an idea how i can fix this problem?
In the release notes of ESX 4.1 U2 i saw, that the problem should be fixed but i still have this problem.
Thanks for your help!
Hi All,
hoping someone can help here.
We've just purchased a VMWare essentials plus license purely for vMotioning as we don't need it for anything else.
I have managed to create a cluster, enabled EVC can vMotion new machines, converted machines fine.
However I have 2 machines, which I cannot vMotion between the hosts.
I keep getting a error about violation
Virtual Machine XXXXXX on host xxxxxxxxxxxx would violate a virtual machine - host affinity rule
I have checked the settings against other machines we have vmotioned and all appear the same.
The thing is though as it's a essentials plus license we're not licensed for DRS and I have double checked and it is not enabled.
Any ideas?
Hi folks.
I have a good sized ESX cluster, with about 20 hosts and Enterprise Plus licensing. I recently did a power down/up of my entire setup, and all but a handful of VMs came back up cleanly. About 5 of my virtual machines came up as "Invalid", and if I try to power them on, I get an error message saying "Failed to find a host for powering on the virtual machine".
Here's what I've tried. I'm working with just one of them now, assuming that once I find the magic bullet for the first one, the rest will be the same.
- Simply removing the VM from inventory and re-adding it (no change)
- Removing it, and adding it to a different cluster (no change)
- Removing it, adding it to a different cluster and different resource pool (no change)
Other VMs in the same datastore, on the same host and on the same resource pool came up with no issues. I'm looking at the vmware.log file in the datastore itself and the last thing that I see in there is the VM shutting down before my power cycle.
I've checked my alarms/settings on my actual hosts, and as far as I can tell it's not an HA issue, but I am definitely in over my head here. My current failover capacity is 9 hosts, and configured failover capacity is set to one host.
The VM itself is a simple config with 2 VCPU and 4GB of ram, and the cluster I'm trying to start it on has 10 hosts, 80 CPUs and 600GB of RAM.
I'm not sure what to try next. I can't edit the settings when I add the VM itself - the setting is not there. (All I have is a power on button, basically)
Any insight would really be appreciated. I'm a relative novice and I'm trying to troubleshoot a production environment as best I can without breaking anything.
Thanks!

I'm running fdisk -l on ESX4.1(not imbedded). But it's stucked... as following
The command not continued... and I cannot inpput anything.
I tried to kill -9 from another ssh session. but it still running... -9 is ok, and confused why it's stucked.
/dev/sdh1 is a LUN of shared storage. I run fdisk -l on another 3 hosts in this cluster. it's OK... only this host is stucked...
we have ten host in the cluster and i noticed all host in the cluster hardware information got refreshed simultaniously at same time, i made sure there is not job schedule to do so. can any one anser me why this could have happend
attanched the screenshot
the host is running ESX 4.1 build 320092 on HP proliant DL380 G6 hardware
Hi All,
Today morning many of my vmware datastores lost access to the NetApp array. See one such error below.
Lost access to volume 4fad3686-2f38ba84-fc46-0025b502008f (Deployment-Conversion-PDT3-01) due to connectivity issues. |
Recovery attempt is in progress and outcome will be reported shortly. |
I checked the storage(NetApp) /etc/messages, SAN switches(my setup is entirely fcp) but could not find anything.. the SAN switches didnt log any port fluctuations or errors. Any idea what I could have missd checking?
Most of the datastores and all the ESX lost connection to its datastores. Few of the datastores didnt lose any connection . The datastores reconnected after a while..Could this be anything from the ESX side since I could not find anything from the storage array or the switch side.
Appreciate any suggestions..
Cheers
