Many data warehouses are hidden when a snapshot is

Hi people,

I noticed that if I have a VM multi-store data from data stores list = 1 when a snapshot is:

C:\ > get-vm-xxxxx name | Get-datastore

Name FreeSpaceMB CapacityMB

-


-


-


TST-XXXXXXX-5095 61184 VOL1

TST-XXXXXXX-VOL2 21986 61184

... Create a wink and run again...

C:\ > get-vm-xxxxx name | Get-datastore

Name FreeSpaceMB CapacityMB

-

TST-XXXXXXX-VOL1 21986 61184

I am writing a report snapshot, and one of the things that I wanted to recover the total size (MB) of snapshots.  I am currently using SearchDatastoreSubFolders_Task for a list of DELTA files.

According to the list of data get-datastore = 1 stores.  Same result when viewing through the VI client.  I see that the .vmx of the virtual machine has the info, I need, but I don't want to use a sealant to get this data.  Ideas on how I can list all the names of data store when a snapshot is?

What you see is actually "working as intended".

Each VM has a property called SnapshotDirectory, which by default is "directory" virtual machine.

The result is that, after a snapshot of the 'new' disk file that saves the changes since the snapshot is located in the base directory of the virtual machine.

To calculate the size of all the files of the virtual machine is using a first, you will need to know on what other warehouses of data/directory there are files present.

This can be done through the Layout.Disk.DiskFile property.

The following script shows how to access this property.

$vm = get-vm  | Get-View
Write-Host $vm.Name "- Snapshot directory:" $vm.Config.Files.SnapshotDirectory

foreach($disk in $vm.Layout.Disk){
  foreach($dev in $vm.Config.Hardware.Device){
    if($dev.key -eq $disk.Key){
       Write-Host $dev.DeviceInfo.Label
       break
     }
  }
  foreach($file in $disk.DiskFile){
    Write-Host "`t" $file
  }
}

  • Formatted VMFS3 ISCSI data warehouses are compatible with ESX5.5?

    Hi all

    I'm currently building an ESX 5.5 environment to run in parallel with my environment 4.1 existing and need the new 5.5 ESX servers to connect via iSCSI to a couple of VMFS3 formatted lun.

    I can't see them via the iSCSI storage adapter, but when I try to mount it asks me to format first. I wanted to confirm if anyone else had this problem or has confirmed that VMFS3 is fully compatible with ESX 5.5 connected via iSCSI.

    Thanks in advance.

    Looks like that the MTU on my NICs is set too high. Once I lowered around 1500, they began to present correct data warehouses.

    Thanks for the help, I think I have a handle on it.

    Thank you, MP.

  • Why CF CV data warehouses are not visible in VCAC

    Hello

    We have after installation

    ESX/VC 5.5 (GA)

    VCAC 6.0 (GA)

    We are able to see all the warehouses of data, local, FC, and NFS in VC.

    We have added VC as an endpoint in VCAC, but we are not able to see the VCAC CF data warehouses.

    Anyone can throw some light on it?

    Thnaks

    Jeannine

    In fact a server in the cluster could not see these CF data storages, solved the problem by removing the server from the cluster

  • Mobile data warehouses are group 3.5 to vSphere Cluster.

    Issue.  I currently have a cluster of ESX 3.5 with a few virtual machines on one of the data stores.  What I was asking is if I grant that the storage (via SAN) to my new cluster could I can implement those virtual machines. on the new vSphere Cluster?  I guess I have to turn off the power, move the storage on the SAN of the old cluster again.  Add to the inventory on the new cluster and upgrade tools?

    Which apparently correct?  Something to look out for?  The only reason I'm thinking it's because a fo the machines has a 500 GB vmdk file store server I can not migrate to the new cluster.

    I guess I have to turn off the power, move the storage on the SAN of the old cluster again. Add to the inventory on the new cluster and upgrade tools?

    Which apparently correct?

    Quite correct.

    Something to look out for?

    That's exactly how I made the last update to an environment of two hosts, where the hosts were replaced and ESX has upgraded day/re-installed 3.5 to 4.0.

  • VM with disks of different data warehouses. Snapshots on the same data store?

    Hello

    We have several virtual machines with disks on different data stores for reasons RAID.

    Last night, we found that the snapshots of all disks are left on the data store main vmx and not on each datastore disk.

    How will we change this as our OS data warehouses are small and run out of space when running shadow copies?

    Thank you

    Frogbeef

    You can change the location of snapshots, but they will all go to this place - as far as I know, you cannot change the location of each disk.

    The KB http://kb.vmware.com/kb/1002929 explains how to do this.

    This is bug #20812030. It is not reproducible on apex.oracle.com because it has been set at APEX 5.0.1. You need to repair or upgrade your installation up-to-date 5.0.2 patch level, or work around the problem by setting the IR position property set to None.

  • Dreamweaver inexplicably & wrong brand png files as hidden when they have not been designated as such.

    Object:

    • Dreamweaver inexplicably & wrong brand png files as hidden when they have not been designated as such.

    Data sheet:

    • Dreamweaver CC 2015.0 release, build 7714
    • Mac o/s 10.10.5
    • Mac Mini (mid-2011), 16 GB RAM, Intel Core i7 2.7 GHz

    Description of the problem:

    • For some reason, Dreamweaver puts the red diagonal line through png files, which indicates that they are hidden when I do I not so designated them.
    • When I use the shortcut menu to reveal to them, the order to disclose is grayed out. I need their coat, and then I can unveil their.
    • Then, when I 'Refresh' my list of files they get hidden once again, at least the red line passes through them.
    • When I have uncloaked them and then put the local folder they are in (after deleting this file on the remote site first for this test) the png do not, but the jpg in this folder and the folder itself got set.
    • In order to upload them to the remote server, I need to manually drag the png on the remote server files. And, even though I was uncloaked first png files, once the png files have been moved to the remote server they get the red diagonal line.
    • Once a file is on the remote site and the red line applied to its icon, I am provided with the context menu options show and not the coat when I select one. This was not available locally, as mentioned above.
    • But then when I unveil these remote png files, and I update the list, the remote files the red diagonal again. Once more the remote png files have the possibility to reveal available in the context menu and not reveal.

    Another thing that is probably unrelated, the files Panel sometimes flashes in quick succession, so much so that it is boring, enough to force me to reduce.

    1. right click on the name of the site in the files, click on curtain-> settings panel

    2. in the dialog box change the settings for what you need.

  • Total latancy in data warehouses

    Hello

    My host has some datastores.one of them have high latency. What should I do?

    We know total latency = device katency + kernel latency if suppose us device or kernel is high, how should solve the problem?

    Thank you

    What I often find that alerts latency for data warehouses are related to CONSIDERING moves. Need large pieces of mobile data respond to a project. Are your warehouses of data showing high without cause latency? for long periods of time?

    I have the internal team of vcenter provide guidance on what they consider the latency for ps read and write ps and make these TOUGH KPI threshold in vcops. So when an alert occurs it is a matter of understanding unplanned planned vs, so it's a matter of drilling data with your experts.

    In my humble OPINION - be admin on vcops does not mean that you know the environment better than your teams... This means that you have useful data to share and then develop the best levels together and the SOP for what latency occurs and the steps to follow. We working through such things now... and test the adapter for Symmetrix. Looking is not on the HBA level so miss us some key data points, but we are working on the adapter to txt and other methods to get better data in vcops.

  • Removal of host SDR data warehouses

    Hello

    I have a scenario where I want to migrate to a host and the VM between two clusters. I unfortunately had a number of DTS data warehouses attached to the host, no virtual machine is running from these storages of data on this host... I'm trying to disassemble stores but as expected get the error indicating that data warehouses are part of a cluster of EIM.

    Is it possible to no disturbance delete Host data warehouses.

    Thank you

    Steve

    So, what you want, remove some cluster DTS data warehouses and pass a host of a DRS cluster to another's is?

    Try the following steps:

    (1) remove the DTS cluster data warehouses, just move the data store outside the cluster for DTS;

    (2) move the host to the new DRS cluster target, if you have virtual machines running on it and cannot put the host in maintenance mode, you will need disconnect host, remove from the inventory and then add the host again to the new cluster.

    (3) If you wish, add data warehouses to the DTS of the new DRS cluster cluster.

    Open a support case and turned out that the POS password user (a user defined in the domain of the @vsphere.local) that was used to access the vCenter has expired. Apparently, there's a bug in vCenter for some versions that makes them expire in 65 days.

  • Assessment vCOPS 5.7.1 - did they add a way to exclude specific data warehouses?

    Hello

    I tried vCOPS in the past and I know that this was not possible.

    I just started a trial now, but I still want to exclude all data warehouses and a couple more which come from a file server that is always 99% full. These data warehouses are not used for virtual machines and shouldn't affect calculations in vCOPS.

    Is there a way to exclude the calculations? Thank you.

    Put all your data warehouses in vCenter the in a folder called "LOCALS" (or something else you like) - this folder will also be known by the VCOPS (may take 5 minutes). Then in VCOPS create a new strategy and clone of "Ignore these objects." On the page of the association take place 'record' and add your folder "INHABITANTS". Check 'current effective policy', it must be on "ignore objects.

    Now, whenever you add a host to vCenter, make sure you put this local data store in the right folder "INHABITANTS". This way you will have exclude them calculations.

  • Performance of BI with warehouse data or data warehouse.

    Hi gurus,

    Anyone here have a document or presentation to compare a BI performance which is implemented with the warehouse database or data warehouse?

    Appreciate your help :)

    You need to come to a conclusion of performance tests.

    The query can also have different points of view;

    1 compare the performance on obtaining data directly from the source systems against obtaining data accumulated in a single database.
    2. by comparing the performance on obtaining data from a standard model against data from a dimensional model.

    In most cases; getting data from data warehouses should give better performance since then.
    Data warehouses allocate more resources toward BI systems.
    Source systems serve much purpose other than BI systems; If resources are shared.
    In a data warehouse for data sets are already in the same place, reducing the latency of the network.
    Data warehouse stores summary information.
    Data warehouses are implemented with three-dimensional models which serves best for the BI queries.

  • What are the best solutions for data warehouse configuration in 10 gr 2

    I need help on solutions to provide my client for the upgrade of the data warehouse.

    Current configuration: database Oracle 9.2.0.8. This database contains the data warehouse and a LOBs more on the same host. The sizes are respectively 6 terabyte (3 years retention policy + current year) and 1 terabyte. The ETL tool and BO Reporting tools are also hosted on the same host. The current configuration is really poor.

    Customer cannot go for a major architectural or configuration to its environment changes existing now due to some constraints.

    However, they agreed to separate the databases on separate hosts of ETL tools and objects BO. We also plan to upgrade the database to 10 g 2 to achieve stability, better performance and overcome the current headache.
    We cannot upgrade the database 11g as the BO is a 6.5 version that is not compatible with Oracle 11 g. And the customer cannot afford to spend anything else than the database.

    So, my role is very essential in providing a perfect solution for better performance and take a migration successful Oracle from a host database to another (same platform and OS) in addition to the upgrade.

    I got to thinking now of the following:

    Move the database and Oracle mart for separating the host.
    The host will be the same platform, i.e. HP Superdome with 32-bit HP - UX operating system (we are unable to change to 64-bit as ETL tool does not support)
    Install the new Oracle 10 g on the new host database and move the data to it.
    Discover all the new features of 10gr 2 in order to data warehouse, i.e., introduction of Clause SQL TYPE, Parallel processing, partitioning, Data Pump, SPA to study the pre and post migration.
    Also at RAC to provide more better solution than our main motivation is to show an extraordinary performance improvement.
    I need your help to prepare a good roadmap for my assignment. Please suggest.

    Thank you

    Tapan

    Two major changes since the 9i to 10g which will impact performance are
    a. changes in the default values when executing GATHER_ % _STATS
    b. change in the behavior of the optimizer

    Oracle has published several white papers on them.

    Since 10g is no longer in the Premier Support, you'll have some trouble connecting SRs with Oracle Support - they will continue to ask you to use 11 g.

    The host will be the same platform, i.e. HP Superdome

    Why do you need export if you do not change the platforms? You could install 9.2.0.8 on the new server, the database clone and then level to 10 gr 2 / 11 GR 2.
