  Thanks for your help!

  Hello

  I have no experience with IBM Storage, but replicated LUN must not be mapped to the ESX host on the recovering site (site B). SRM should do the mapping when you perform a failover (or create and map the snapshots when test).

  Check again your configuration of the SRA. I think you missed something.

• Local storage and multiple ESXi hosts

  Hi, I was wondering how vWorkspace manages local storage in an environment with a single server Vcenter and two ESXi, with a local data store each.

  If I store a 'master' (I mean the gold statue) vm on the local storage of an ESXi, can replicate vWorkspace this virtual machine to the local storage of the other ESXi as Citrix VIAB?

  If not, how can I use both my ESXi servers with local storage and maybe provide some sort of HA?

  Am I forced to use a storage shared, if I want to be able to deploy clones related both to my ESXI?

  Thanks in advance.

  Hello

  Use vSAN, or no matter what virtual SAN Appliance as an iSCSI SAN storage to prosecute two storage facilities... You can replicate between the two servers and same LUNS are used by vWorkspace.

• Slow VMFS / Rescan HBAS with fiber-attached storage

  Hi all

  I use ESXi 4.1, build 260247 with fiber storage attached my NetApp 3240 controllers on the version 8.0.2.  I'm trying to use plugin 1.0 host OnCommand of NetApp to save my VMs.  For those who don't know, doing essential software works with vSphere and the table to create screenshots instant table based and replicate to the Dominican Republic.

  It works very well.

  When I have a problem is the restoration of VMs.  The restore process is slow.  Using the same software, what is done is to present table for the ESX Server hanging and set up the data store.  This also works, but VMware must rescan the HBAS and VMFS several times.  Because of the long duration to rescan the HBAS / VMFS, this editing process may take 15 minutes or more and seems rather excessive to me.

  Does anyone have any ideas why the rescan is slow or it is normal and just something I have to deal with?

  Thanks in advance for the help.

  Michael.

  Does anyone have any ideas why the rescan is slow or it is normal and just something I have to deal with?

  You have the ability to limit the maximum number of LUNs?  For each host, go to the Configuration tab, select the disk and get off at Disk.MaxLUN.  The default value is 256, but if your maximum lun number is much lower than that, drop this value down to speed up scans.  See http://pubs.vmware.com/vsphere-4-esxi-installable-vcenter/index.jsp?topic=/com.vmware.vsphere.config_fc.doc_41/esx_san_config/managing_san_systems/t_change_the_number_of_luns_scanned_using_disk.maxlun.html

  If the LUNS are contiguous, you can also change the Disk.SupportSpareLUN from 1 to 0.  Who told him to stop as soon as a logical unit number is missing.  It is bad if you have LUNs 2,3,6 because you never see lun 6.  See http://pubs.vmware.com/vsphere-4-esxi-installable-vcenter/index.jsp?topic=/com.vmware.vsphere.config_fc.doc_41/esx_san_config/managing_san_systems/t_change_the_number_of_luns_scanned_using_disk.maxlun.html

  Hello

  Make sure that D: is not the partition recovery including the manufacturer put there to make the recovery disks from and eventually to return your computer to how you bought

  You cannot combine C: and D: and their data using the Vista Disk Manager

  with Vista, you will need to save the data on D: - D: delete - and then extend C: into the now unallocated space where D: was to do a 1 partition 2

• It is possible and effective: high availability (failover) on 2 guests with local storage?

  Hello

  I have a discussion on the implementation of ha (failover) with 2 guests with local storage.

  My advice is to go with a shared storage. But there is another view, use the cluster failover MS with local storage service to save on the shared storage hardware.

  2 "mirorred" on each host machines. Is it feasible at all?

  The HughesNet: have 2 virtual machines (SQL server and server applications in a highly available environment). The workload of the machines will be raised to 2 very powerful servers that are supposed to be buying.

  1. Please briefly explain a feature of local storage to provide HA.

  2. I got to cluster in the virtual environment, not so I guess that the shared storage is used only in the virtual environment.

  Thank you.

  Michael.

  There is software that can replicate a running, physical or virtual machine to another accessible location on the network. This could be as simple that between two close hosted ESXi of VMS or high-speed WAN. Take a look at things like neverfail, doubletake others.  The costs would probably be a bit prohibitive in a smaller environment. It might be possible and maybe even practice to use a virtual storage device having a failover replication. Use of storage on each host and allows to provide the data store. Open-e

• Need help with hardware (storage of 1 servers)

  Hello world!

  We want to put all our production and testsystems on ESX servers. We also have a redundancy, so that if a server fails, it could host all systems for the time beeing.

  We contacted Dell fo a nice solution and came it with 2 x 1950 and 1 MD3000. I know that we can not all HAL and vMotion with the MD3000, but for our purposes it would be bad enough if we could start these systems manually on the other server.

  As far as I understand is that both servers share the same storage and are locking the vmdk when used, am I right?

  I posted our HW we'll buy and I would be really grateful if someone could take a look and give their opinion on this system:

  Well learn you something new every day.

  You can share a logic unit number between two servers from an array of SAS switching, IE the MD3000 you look. Of course, you are limited to two servers.

  You'd be surprised iSCSI how fast is. Just because it's ethernet does not mean that it is slow. At my last job, we had a NetApp FAS3020 with FC and SATA disks connected to eight cores double 32 GB ram ESX host ~ 160 running virtual machines, and they have recently bought four servers dual quad core more with 64 GB to support ~ 120VMs.

  Certainly depends on what are your virtual machines, in your case, you can do much more disk IO and feel the need to drive faster, but a number of virtual machines in the environment above have been weather data processing and real-time flight.

  That said, if you do want to grow then two ESX hosts, will spend SAS keep things simple. I'll have to see on one of these loans...

  Good luck.

• VM ESXi 2 times with 2 vCPUs and 3 vCores

  Hello

  First offshore, I use ESXi 5.1 and the sage of material I use is 2 x Hexcore X 5650 2.67 GHz, 48 GB of RAM and RAID 1 SAS 15 k disks 600GO

  I ran into a problem where I bought a server spec higher to go along with our other our dedicated hosting company, however, I went Dual cores to processors dual hexcore that now puts me over my limit of 8 cores on ESXi.

  So my question is, that I can only use a maximum of 8 cores per virtual machine and I have 12 available physical cores, would be 2 virtual machines with 2vCPUs and 3 vCores use all 12 physical cores, or would it still restricted to using only 8 of these carrots?

  Also, wouldn't be good (balanced load) the idea of using 2 VM with 2vCPUs and 4 vCores?

  All advice and guidance welcome.

  Hi Welcome to the communities.

  I went from double hearts of processors dual hexcore that now puts me over my limit of 8 cores on ESXi.

  The limit of 8 cores is without limit to the ESXi, but for virtual machines. Your ESXi can use all cores of your physical. Your virtual machines can only use 8 vCPUs (up to the standard license. Enterprise and Enterprise plus can vCPUs 32/64)

  So that already answers your question:

  So my question is, that I can only use a maximum of 8 cores per virtual machine and I have 12 available physical cores, would be 2 virtual machines with 2vCPUs and 3 vCores use all 12 physical cores, or would it still restricted to using only 8 of these carrots?

  Your ESXi host will use all 12 physical cores. By default, each vCPU contributes to a logical core, which is a physical core if you disabled hyperthreading.

  Also, wouldn't be good (balanced load) the idea of using 2 VM with 2vCPUs and 4 vCores?

  I would recommend not only to assign as many vCPUs to the virtual machines that you can, but start with little vCPU and increase in this number, as you can see on the guest workload is high that you need more vCPUs. less can be more in virtual environments, try not just to migrate your 1to1 physical servers to virtual.

  For quick theoretical example: If you got 4 physical cores and 2 VMS with 4 vCPUs each, each physical heart will serve 2 vCPUs. In this example two virtual machines can run faster with only one or two vCPUs earch.

• Controller of active/active storage and ESX 3.5 U4

  My SAN controllers are configured as active/active, both quick (?) question.

  ---

  Can I not load balance my ESX 3.5 host traffic HBA (2 HBAs for each host of course)?  Manage the paths of dialogue shows ' round Robine as "Experimental" only that I'm obviously not to use in production.

  My guess is that I can't have ESX host HBA not experimental load balancing up to what we have upgraded to ESX 4.0... I just wanted to hear here officially I can tell my boss ' see? We HAVE upgrade for it, you fool! »

  With 3.5 and active/active storage, good politics is fixed path.

  The load balancing is experimental.

  Or you need to upgrade to vSphere.

• How to remove the local partition of storage and vmfs

  I have esx 3.5 on a 6 infrastructure hosts. Each host, in addition to other stuff, I have a 6 GB VMFS partition, "tied" to a local storage.

  I did not install, so I do not know the purpose of this partition, but there seems that it is not used, because it is empty.

  Now I need free space on the hosts to install monitorning of IBM tools, and I thought that it was preferable to have these installed NOT on the partition root.

  Since I have this 6 GB partition (hopefully) unused, I if I could remove the storage, delete the partition VFMS and create an EXT3 partition.

  But I do not know how... can someone tell me the exact procedure I should follow?

  Some information about my environment:

  the VMFS partition is sda3:

  Disk/dev/sda: 14.9 GB, 14999879680 bytes

  Heads of 64, 32 sectors/track, 14305 cylinders

  Units = cylinders of 2048 * 512 = 1048576 bytes

  Device boot start end blocks Id system

  / dev/sda1 * 1 100 102384 83 Linux

  / dev/sda2 101 5100 5120000 83 Linux

  / dev/sda6 12225 14206 2029552 83 Linux

  14207 14305 CF 101360 unknown sda7

  And I have this virtue/vmfs/volumes (ensv16oe:storage1 is the local storage, I want to delete):

  # ls

  48bedd8b-7fe7ff6e - 36 c 5-00215e2097b4 Datastore1

  ensv16oe:storage1 is on vmhba1:4:0:3

  Thank you for your attention.

  The restart was not necessary also if fdisk say Yes.

  A different way has been to say the least the VMFS volume empty, change the type with fdisk, forcing a new analysis and verify that the data store is gone.
