Strorage VMFS on ESX 3.5 host with multiple disks

• Photos of virtual machines with multiple disks on different LUNS - Question

  I have some questions on how to manage the snapshots of virtual machines with multiple disks on different LUNS.  First of all, the LUNS are VMFS.  We are just starting to add virtual machines with dedicated for data storage format VMFS LUNS.  I don't think an extra space must be made for snapshots, as well as at least 100 GB LUN is required to store the data, and then say, add about 25 to 50% of this amount?  Set the 100 GB vmdk file but have the GB from 25 to 50 additional disk space for snapshots, if necessary (rather than just to get a unit number logic needed 100 GB of data and devote all of the 100 GB to the vmdk file).  In addition, if a virtual machine has several files vmdk on different LUNS, which will be a problem to take a snapshot, and is it possible to do just a snapshot of a disk of a virtual computer (as the volume of the BONE)?

  Thanks for any help.

  Snapshot files are created in the home folder of the VM by default for all virtual disks, no matter on what data store they are. You must make sure you have enough free disk space on the data store for snapshots.

  If you want to exclude a virtual disks of taking snapshots, you can set it to 'Independent' - 'Persistent' machine virtual settings to the HARD drive.

  (1) see the vcenter and esxi version, you cannot add higer version esxi on low vcenters version. and also 2) check the dns resolution on the two esxi as well vcenter.  (try adding with the IP address of the host). If it is not the case, check the logs of Vpxa

• Connect an ESX host 4.0 in a store of data VMFS 3.31 with vMotion, and ESX 3.5 hosts

  Hello

  I moved 2 x a new vCenter 4.0 3.5 ESX hosts.  I also have a new ESX 4.0 host.

  Can I connect this ESX host 4.0 for the data store using the 2 x ESX 3.5 hosts?  It is a VMFS 3.31 on a CX3-20 SAN data store. I was then going to vMotion virtual machines to the new host and reinstall the old.

  I just fear that the new ESX 4.0 host will do something to the data store that make it incompatible with the older ESX 3.5 servers.

  Thanks in advance,

  Euan

  Yes, you can connect and use these data with ESX versions warehouses. If you have sVMotion it will work as well. On ESX 3.5 you can only move the guest as a whole on an ESX 4.0 host, you can move the vDisks independently.

  It is perhaps unnecessary, but when I update the ESX 3.5 servers 4.0 I unplug the storage until the update is running. Just in case...

• Upgrading to ESX 4.0 host autonomous with local storage to ESXi 4.1 on a USB

  We have a stand-alone host with a single raid array that is local to the server at a remote site from ours.  The question of what I've done research, you need to reformat the raid array if you install ESXi 4.1 on this host.  Since there is no shared storage, the only option would be to copy the data from one server to another, or maybe install ESXi on a USB key.

  It seems to work fairly well in a test environment.  Are there warnings that I may have missed when I take a system that can be started locally on ESX 4.0 and change it to boot from a USB key with ESXi 4.1?  In my test environment, I know that you can not install ESXi 4.1 on a USB key, if this system had ESXi 4.1 installed on the local disk.  He ended up giving me the GROUP when he discovered another ESXi installation.

  Thoughts?

  Matt

  As you may have noticed a new ESXi installation will wipe away the installation partition.  If you have just a single Bay, then you'll want to go to the root of the USB.  If the data store was on a LUN or a separate table, then you'd be OK to install ESXi on ESX.  As long as the boot order is set correctly, you'll be fine.

  In my test environment, I know that you can not install ESXi 4.1 on a USB key, if this system had ESXi 4.1 installed on the local disk. He ended up giving

  me the GROUP when he discovered another ESXi installation.

  What kind of system did you use for testing?

• Naming of the ESX hosts with the underscore. Best practices?

  I was curious as to what that the general eager to name the ESX hosts with underscores "_". I found an old post in 2006 related to it:

  http://communities.vmware.com/thread/64885

  In the thread, it is usually frowend against because she not compling with DNS internet naming standards. The underscore character is not recognized by the Web servers.

  He has been wondering if there would be no advantage to include similar underscore characters with no routable ip subnets, 192.168.x, 10, etc...

  If you have designed it correctly you already have your hosts on a subnet that is not routable, so you would get no real benefit.

  Beyond this thought experiment, there are problems with your esx host with ESX, vSphere, vCenter naming universe underscores?

  Just an info

  All my guests have underscore in them. I had to replace all of them with a dashboard because ESX 4.1 will not accept underscore after upgrade to the console.

• ESX 4 U1 hosts Lock with SD 0:0:0:0 still a retry after 360 s

  We are just past BOF ESX3.5 to ESX 4 U1 a few weeks back. We are running on an IBM Blade Center S with blades HS21-7995 and using the Module SAS RAID for storage.

  On two occasion, all the arrested respondent/VMS ESX hosts were offline and on the console of each host appeared - SD 0:0:0:0 still a retry after 360 s.

  After power cycling the blades and chassis of BCS, everything is back online.

  Each host has a 20 GB on the START SAS RAID volume that is mapped to the blade.

  This facility has been stable for more than a year on 3.5 and started this problem after the upgrade. The first time this has happened subsequently, I rebooted all hosts with a fresh install of ESX4 U1 after the failure of the volume. We have experienced this new yesterday morning.

  I'll probably open a case of pension with Vmware and I already talk to IBM as well. Any ideas or suggestions are appreciated.

  Newspapers, will be the starting point. Unless it's a known issue for IBM and VMware you will need to collect newspapers from the time of the problem. You have all the firmware update?

• Cannot add the ESX 6.0 host to vCenter Server 6.0

  OK, I'm testing laboratory a vsan 6.0 cluster.

  I have my running 6.0.0 esx hosts and vcenter server is 6.0.0 also.

  I have the services platform on a virtual machine and vcenter on another. I was able to create a data center, then a cluster below.

  Then I went to try to add a host to my group and I get this error...

  Failed to contact the specified host (hostname\IP). The host may not be available on the network, may have a network configuration problem, or that the management on this host services may not respond.

  
  

  Per this KB: KB VMware: Add a host VMware ESXi/ESX from VMware vCenter Server fails

  
  

  I confirmed that my vcenter server and platform services server can see all esx hosts. From the vcenter server, it can ping the host esx and PuTTY can access all of them. I even installed the client and it can connect to all esx hosts. I used the netbios name, IP and FULL domain name and they all work.

  I have only a single subnet, so this isn't a problem. DNS resolution works in all areas of both sides, vcenter esx hosts and host esx to vcenter.

  
  

  I am quite puzzled.
  

  
  

  
  

  OK, after working with VMware on this issue, I think that I thought about it.

  All my hosts are DL360 G6 servers.

  My hosts are run the same build «VMware-ESXi-6.0.0-2494585-HP-600.9.2.38-Mar2015.iso» ESX Downloaded from HP.

  All buildings are in trial mode.

  After placing a call to VMware, they had me build some ESX VM, the services of the platform and the vcenter VM on an ESX host. We suspended because it took all day to go upward.

  Once I woke up all the parts (sql server, esx vm, server platform & vcenter) in virtualization nested, I created my data center, then Cluster then added the ESX host.

  The hosts added properly, no error. Then I remembered when I installed ESX inside a virtual machine, I am angry that the iso, I had the habit of HP does not work in my VM nested due to virtualized hardware.

  Then a fire came into my head. We will rebuild all of the physical cluster but NOT use the CV provided the iso file but use VMware provided iso file "VMware-VMvisor-Installer - 6.0.0 - 2159203.x86_64.iso".

  I did it today. I have rebuilt all hosts with the provided iso file VMware ESX...

  Spun SQL Server vCenter, service platform, all VM VM VM you need. My AD & DNS VM are on another server, so he has been upwards all the time.

  Connected to the web interface (yuck!).

  Created my data center...

  Created my Cluster...

  Add all my Cluster hosts.

  All of this worked!

  Therefore, if you encounter the same problem, I'm plan to generate your with the provided iso file VMware ESX hosts and try it. In my case, the provided HP iso file didn't work properly for me.

  I also downloaded the iso file of HP 2 other times to make sure and do a validation test and it did the same thing.

  Very much appreciated to help him.

• Custom list VIB in ESX 4.1 hosts?

  Is there a quick way to enumerate all VIB custom in ESX 4.1 hosts running data center?

  I got about 30 VMhost and wondering if it is possible to enumerate all of these custom VIb before I level to ESXi.

  Thank you.

  As you can see on the returned object, there is no piece of software in there.

  The vibs can be registered with this method in vSphere 4

• Can we do vmotion between hosts with load balancing in network cards grouping different strategy.

  Hello

  We are implementin new host in our Infra and do some vmotions between different groups. A group a host with balancing 'route based on IP hash. " Can we do Vmotion to another cluster where the hosts have different load balancing policies. In addition, if we change the policy on new hosts in furture of load balancing is loss of downtime or a package?

  Kind regards

  Vikram Kumar

  First of all, no problem from VMs one ESX to another, they use different political Multipathing.

  Second, if you use IP hash, it means you are using etherchannel (or LACP) on the physical layer - configuration/cancellation of the configuration that almost always require that the uplinks are not used by any VMs, so you have time to synchronize the physical and virtual configuration. It is not a time out, but you need to plan accordingly - all depends on your physical network capacity.

• VMotion between 2 Hosts with different processors

  Hallo,

  I have a server in my homelab I use for studies of VMsphere and I want to get a second machine to test advanced features such as HA, Vmotion etc.

  My first server has a map of X9SCM-9 with processor Xeon E3-1230V2 (Ivy Bridge). I am currently running ESX 5.0 U2 on it.

  I was counting on obtaining of material quality for the second host consumers because I don't want to spend a lot on it, so I thought that I need any CPU generation Ivy Bridge.

  I tested today with a second machine with a Pentium G2020 Ivy Bridge, but when I try to Vmotion he says "the virtual machine requires physical features that are not available or disabled on the host... ».

  So I figure there must be a difference in architecture regardless of the CPU beeing an Ivy Bridge CPU.

  When I try to activate CVS it just me are going to the 'Nehalem' Version so my virtual machines running on host 1 would not be able to use all the features of the CPU since the Xeon.

  So the question boils down to: what is the processor less which offer compatibility VCA L5?

  Or is there something else to consider in VMotion between two hosts with different processors?

  I got a shared storage, etc. of the same network configuration.

  Thank you

  Benjamin

  Hi Benjamin,

  For compatibility VCA L5 want to look at one of the following models, Intel CPU:

  • Ivy Bridge: Series E3-1200-v2
  • HASWELL

  I would recommend mental health that before rushing and a CPU purchase, check if a cheaper option would be, as Jon mentions in suppresss some fo the CPU compatibility checks so obviously, this is not desirable in a production environment, and must be applied in your study of VMware Lab to the home address.

  Hope this helps,

• Upgrading memory on ESX 3.5 hosts

  Hi all

  We are trying to upgrade the memory of our esx 3.5 hosts.  If we properly close the guests, then we properly stop the host, will be the guests of vmotion.  According to me, they won't, but I was curious to know if it is happen.

  If the guests are turned off, then stop you hosts, there is no HA/DRS.  All guests will stay in an engine out of State until the ESX host come back online.

  If you have vCenter with vMotion/DRS, you can do a rolling upgrade.  vMotion all guests to another host in the cluster, put vacuum host in maintenance mode, it off, add RAM, if power return, exit maintenance mode.  Rinse and repeat.
