• Do we know how the data store is filled

  We do not know how the data store is filled, ran put space, is there a tool or a way to get the report how the data store is filled.

  1. go to the data store--> select storage views--> then apply different filters to see DS space utlization by VMs, instant.

  2. enable ssh esxi host and log in with the username/password of root and orders below

  #cd vmfs/volumes /.

  #du-sh *.

  This will list all the files/dir on this data store and its size in GB.

  3. or you can use DS to take a quick look at what.

  Thank you

• Too many data stores appearing during the creation of Prot Grp

  I have a problem when you create a new protection group in SRM 4.1.

  Background:

  I am trying to protect only 2 virtual machines (vmsql 1 and vmsql2) that are on the same data store (datastore5). However when I run the new protection Group Wizard, srm trying to protect the 2 vms above on datastore5 AND 4 other data warehouses (and their virtual machines).

  This "behavior" is usually because a virtual machine was a 'link' to another store of data EG one or more of its VMDK resides on other data warehouses or he has a link to CD with an iso on a different data store.

  I checked the 'change settings' vmsql1 & 2 and all their VMDK (and RDM) are on datastore5 and there is no CD of iso connection.

  I went through datastore5 and the only files / folders on datastore5 for vmsql1 & 2 (except hidden for distributed switch folders).

  I looked at the other VMS (I don't want to protect) to see if they have all the settings for CD or vmdk linking them to datastore5 and there is nothing obvious.

  So my question is... Whats connecting these other 4 data warehouses to datastore5?

  I: vc restarted on both sites, rebooted srm on the two sites, reanalyses berries from srm on both sites and re-analyzed VC (in two places), data warehouses also led lsof and ls - la on the esx hosts, but nothing unusual turns

  More info: vmsql1 and vmsql2 have been passed to datastore5 recently - off voltage and storage-vmotioned on datastore5

  Hello

  No doubt those LUNS are part of the same group of coherence on the storage array.

  When MRS. detects a consistency group, it places all of its LUNS in the same group of data store.

• Data store mobile (vm machine) 1 host to another with the help of free hypervisor on the two hosts

  I have 2 hosts running ESXi 4.1 (free version of the hypervisor). Both have their own data store locally.

  I need to move a VM machine (data store) of a host for the other local data store. There best way to do this with the free hypervisor?

  Hello

  Using VMWare Converter standalone 4.0, it's a free VMWare tool exactly for situations like yours. I use the conversion tool to transfer my virtual machines much between different hosts of ESXi and also founded to convert ESXi VMs to VMWare Server/Workstation and vice versa.

  All you need to do is turn off the virtual machine and make sure that it is in the inventory of the ESXi host source; Use the VMWare Infrastucture option while selecting the source and the destination of VMWare Converter Standalone, you will be asked to provide identification name and connection of your ESXi source servers and destination information.

  VMWare Converter Standalone is a brialliant tool, its very flexible in that you can resize your hard drive, use a provisioning, edit all devices.

  Hope this information useful for you.

• Be able to disconnect a data store without deleting an ESX host

  I want to have the ability to disconnect a host from a data store without deleting everything in it.

  Today what I understand, if I never connect a host ESX/ESXi in a shared - data store it will be there forever, even if no VMs is running on the host computer it seems not possible to simply 'disconnect' or 'remove' it. I found strange.

  I don't care

  If ESX sees VMFS LUNS and LUN is right LUN ID (it is written in the signature) ESX automatically connects to this VMFS datastore.

  LUN mask, detach the cable - just make inaccessible LUNS for this particular ESX.

• How many network adapters should I showing in Device Manager?

  I have a connection to another pc at home wireless, NICs (2) listed in the Manager of devices Belkin Wireless USB adapter is one, why I ordo I need each other is NVIDIA nforce 10/100 Mbps Ethernet?

  It seems that your computer has both a wired (10 / 100 Mbps) card (adapter) and a wireless adapter.

  You don't need to have both of them enabled (you have to activate one of them).

  Your wired connection will probably be more Rapids (100 Mbps) as your wireless connection. It will also not be subject to intervention by your neighbors.

  Wireless connections are convenient for portability, but may suffer interference from your neighbor's wireless connections, and/or have degraded performance according to the distance and obstacles that esist between your computer and your wireless router.

  If your computer is a desktop computer, you can consider using the wired adapter and the deactivation of the wireless card.

  If your computer is portable (for example, a laptop computer), then you can use the adapter (activate) the wireless and disable the wired (Ethernet) adapter.

• Machines MSCS with RDM, how to change the data store?

  
  Hello world

  I'm having a problem of displacement of 2 machines with RDM disks.
  We have 2 guests ESxi 4.1 with virtualcenter, but no license for vmotion.

  This 2 machines is building a MSCS Cluster (Microsoft) (file server) with multiple disks (5) RDM,
  for a total area of 8.9 TB. Of course, for use with MS cluster, the WDR is with physical compatibility.

  The problem is that the local vmdk (and also rdm.vmdk files) for these 2 machines are on the local data store (a machine for each host) and I need to move them to the shared storage. But if I power off of a computer and trying to change with the ROW data store attached, I get an error because the VMFS of the commune dastore (block size = 1 MB) does not support these large files (up to 2 TB).

  I read a lot of articles
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1031041
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1026256
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1002511
  and a few other discussions of communities.

  In accordance with article
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1005241

  I tried to turn off the machine, remove the RDM, migrate to another data store, and then reconnect the RDM.
  There is a big problem with the last point, because I don't know how readd the RDM manually (vmfsktools?).
  I want to add an existing drive, but he was in local storage, and I don't want more no reference to the file in the local storage...
  According to the documentation of vmware for MSCS, the second node of the cluster disks can be added simply to add a drive existing and selecting the
  existing node. If it is no problem of shared storage, but the host cannot read local storage to another host...

  Any suggestion to migrate a computer virtual with RDM shared storage room? Thank you

• How to add a logic unit with an existing data store number

  I have a logic unit number I replicated from a SAN at a data center in a SAN to another data center. I want to map this LUN to a cluster of ESX 4 and use the store of existing data on the LUN to recover the virtual machines it contains. What is the best way to do it? Guests will see the existing data store, when I rescan HBAS or y at - it a trick to add a data store existing cluster?

  It's a separate LUN on a different SAN mapped to another set of hosts. Once I have a new analysis for the new LUNS and data warehouses, store data on this LUN will display in the list of data stores to then browse data warehouses and register virtual machines on it?  Or still do I add storage and first select the existing data store?

  Given that the hosts did not see the original LUN before, the data store should appear just after the new analysis.

• How long does take to dismantle and re-scan a single data store

  Hi all

  I am currently using vSphere 5.0 to manage 3 x 5 ESXi hosts. I am trying to use the host VM 2 for surebackup data store and virtual laboratory of Veeam. I had already used the same data store and removed. Now try when I set up again on the same data store, it generates the error Create NAS Datastore - specified key, the name or the identifier already exists.

  After reading about the issue, I've seen the way to solve this must dismantle and Reanalyze the data store that produces the error. As I've never done this before that I was wondering if someone could share their own experiences? I need to move the exisitng s VM from the data store before I have to dismount and perform a new analysis or any point throughout this process?

  Some details on the data store:

  Composed of disks SAS 4 x 300 GB in RAID 5 with a total of 831,50 Gb. There are 8 VM running on this server using 400 GB on the Go 831,50. 4 virtual machine are essential and must be operational during the time leading to opening (9 - 5.30 pm). These total 222 + 39 + 33 + 69 = 363 GB. The data store is not shared between hosts.

  The migration of virtual machine for the other guests, I'm able to estimate (if necessary). What I'm really interested in is the length of time that it will dismantle and Reanalyze the data in question store.

  Any help would be much appreciated.

  Thanks in advance.

  Kind regards

  Haydn

  You must move the virtual machines before you take it apart

  or close the virtual machine and to unsubscribe to esxi.

  given that the data store is not shared, you must do the migration of data store for virtual machines such as migration cold.

  Disassemble and analyze new shouldn't take more time, let's say less than 2 minutes if each works fine.

• Expansion of data store which is the best way?

  Hi all

  I want to help you on the extension of a data store. I have a HA cluster with three hosts (5.5 ESXi). the army actually share a single data store where all the virtual machines to run. the data store is created in a midsize V3700 storage ibm. the host is connected with the CF. But I want to extend the ability of the data store. I think that it is possible to do this in two ways:

  -creation of a new volume of the midsize IBM and by mapping it to all the host then developing the data store for the new LUN (extension) created.

  -expanding the existing volume of storage IBM midsize directely. While it is the ability to store data directely is increased.

  I need your help because this cluster runs mission critical VMs. Also, I read in VMware documentation that it is not recommended to use more than one number of logic unit by the store of data that each data store should be in a separate logical unit number.

  How would you propose?

  Can you do the manipulation without stopping the virtual machines?

  I'm not familiar with the storage system you use, but these storage systems are generally several controllers that can be owners of LUN presented to the hosts. With the help of only one data LUN/store you are actually 'wasting' performance, then you can consider to introduce a different unit number logic with the second controller of storage as the owner LUN and create a second data store for your virtual machines.

  Regarding resizing datasore. With ESXi 5.5 there is no more need to use extensions, i.e. to present another logic unit number and add it to the existing data store to increase its size. You can simply increase the LUN size up to 64 ~ to, rescan storage on your ESXi host adapters and then increase the size of the data store in the Properties window.

• Configuration of San - data store have more than 1 LUN

  Hello

  We look at our San configuration for improvements. Our San has about 10 TB total.

  We currently have 6 LUN 1.5 TB all which are enclosed in 1 store 10 TB data

  It was suggested that we should NOT combine multiple LUNS in a data store for the reason if 1 LUN goes wrong then the entire data store is non-refundable.

  Although our SAN LUNS are created on top of raid 6 and are therefore a bit 'protected' by councils LUN 1 data store is interesting

  Does anyone have ideas to share?

  Thank you

  Tom D

  I would say that having a single data store, regardless of the underlying storage architecture is probably not a good idea.  Although this configuration is authorized you can paint yourself in a corner fairly quickly.

  1. one wonders about the maximum number of VMDK you should have by the data store.  http://communities.VMware.com/message/944120  Basically the more s VMDK on the SCSI data store more blocking of activity taking place on the disk, causing performance problems.  Each VMware engineer, I've talked about seems to stay around the VMDK 20 a range of data store, but that could change with vSphere.

  2 - How this data store backup and how long does it take?  What happens during a restore scenario?  10 TB is plenty of space and could take some time for the backup.  If you push it on tape and you must always restore the together 10 to it could take weeks or months.  This space by breaking into warehouses of smaller data gives you smaller segments of data that you can restore in case of disaster.

  3 - the number of data warehouses you have is very important if you are always looking to implement the Site Recovery Manager.  SRM relies on your storage device to replicate data between the sites.  There could be serious consequences on the rate of change of the data for a single LUN 10TB.  If you are moving in several data stores that it will make it easier to handle your recovery plan.

  Apart from the considerations above of VMware. I guess 7 performance LUNS in RAID-6 is not so great.  You have a lot of protection, but you pay for it with capacity and performance.  If you went to 10 stores of data and the LUN 10 you can change RAID settings at each data store to optimize performance, protection, and capacity.  For example 4 LUN RAID-10 high performance DB apps and 6 LUNS to RAID-5 for the ability.  With smaller LUN and data warehouses a disk or LUN failure will affect only a smaller set of services rather than your entire data center.

  In short, unless there is a really compelling reason to go with a single store of 10 TB database, I recommend you to change your architecture.

• promotion of iSCSI LUN with the VMFS data store

  Hello

  I moved an iSCSI on the website of DR SAN and fact volume so that it was accessible to the ESX host on the site of DR based on the IP address and made the new analysis of the adapter for iSCSI Software in the VI Client on the two hosts on the DR site and he discovered the LUN.

  I don't want to go to the Configuration, storage and add storage as this reformatted the volume and it has a VMware Server already on it running happily on the main site.

  How can I add the volume as a VMFS data store available on the two hosts as he is picked up automatically?

  Thank you

  Paul

  I guess it was a VMFS volume that was used by the ESX environment on main site you, Yes? If you have moved the LUN, i.e. the ESX hosts in the main site no longer have access so that the ESX host at the DR site do not have access, you will need to define EnableResignature = 1 under Advanced settings, LVM

  You restart the analysis for storage and you should access your VMFS volume. You will need to register your virtual machines with the new host.

  When complete set EnableResignature = 0
