PowerCLI script for DatastoreCluster, data warehouses and the size info, DataCenter, Clusters

• The list of virtual machines, data warehouses and the folder name by cluster

  
  Hello!!  I hope someone can help me with a PowerCLI script that can pull the info from the object into a file, txt or csv.  In order to get our environment cleaned before our next year Dr. with MRS, I want a list showing each VM and the data store (s) in that it is the name of the folder in the virtual computers view and models.  We keep our VMs organized by creating folder names that correspond to the application running on the virtual machine.  I mention a SRM than last year because our protected groups matched groups of our table of 3PAR Rcopy.  However, we have added over 200 new virtual machines from this era and the members of my team essentially placed these new virtual machines on the first available data store that had enough free space.  Unfortunately, we are not using storage profiles... it's scheduled for next year.

  Information extracted would look like the following:

  ServerName Datastore folder name

  Server1 LUN0 ActiveDirectory

  Server2 LUN0 ActiveDirectory

  Serveur3 LUN1 ActiveDirectory

  Server4 LUN3 Argo

  Server5 LUN7 Argo

  LUN6 Lockbox Server6

  LUN5 Lockbox Server7

  Serveur8 LUN9 Citrix

  etc...

  Any help with the extraction of this info from vCenter would be greatly appreciated.

  Thank you

  Charles

  You can redirect the results to a CSV file, for example

  Get-VM |Select Name,@{N="Datastore";E={[string]::Join(',',(Get-Datastore -Id $_.DatastoreIdList | Select -ExpandProperty Name))}},@{N="Folder";E={$_.Folder.Name}} |Export-Csv C:\report.csv -NoTypeInformation -UseCulture
  

• PowerCLI script to migrate virtual machines to the new vCenter environment

  Hello world

  in the next few weeks, we need about migrate 700 VMs (Windows/Linux) server to a new environment (new vCenter, new hosts, but VMs will remain on same data warehouses). VMs will be migrated not in one batch, but rather from time to time (which, however, can understand the need to migrate some 10s of virtual machines at the same time).

  Cluster names and folder structure will be identical to the old and the new vCenters. As host in the new vCenter names differ from those in the old vCenter, thought to provide a table of 'translation', which tells the script to save a given VM on host B (new vCenter) when having been registered in order to host a (old vCenter) and so on.

  I thought writing a PowerCLI script which, broadly speaking, can accomplish the following steps:

  • Connect to vCenterOld and vCenterNew
  • Correspondence table of host to read from a file (see step "register VM vCenterNew below)

  Then, in a loop:

  • Ask VM name
  • Get the settings of the virtual machine: Datastore/path, network/Portgroup, HA restart priority, host, folder, note
  • View the parameters and the VM name and request confirmation migrate the virtual machine
  • Turn off VM (closed OS gracefully, but force power off if power status is still not equal 'off' after a time given)
  • To unsubscribe from VM vCenterOld (removal of inventory)
  • Registry of the VM to the data store vCenterNew (assumptions: same folder as vCenterOld, host names are different, but for each source in vCenterOld host a host of destination in vCenterNew for you join the virtual machine to can be provided, that is, CSV)
  • The value of VM portgroup (same name as in vCenterOld)
  • Set VM HA restart priority
  • PowerON VM
  • Wait / check the VM (for example, ping) connectivity / continue immediately if the virtual machine is accessible or after a certain time if the virtual machine is still inaccessible
  • Confirm that the virtual machine has been migrated successfully, OR ask the user to check the connectivity of the virtual machine

  Now to my questions:

  • Is anyone know about an existing script that does something similar or contains parts that can be useful to compile a script like this?
  • How can vCenter two connections at the same time been managed within a PowerCLI script - or doesn't work at all and a connect/disconnect to/from the two vCenters must be completed for each virtual computer?

  Many thanks for any help.

  The following seems to work for me

  $vm = Get-VM -Name MyVM$nic = Get-NetworkAdapter -VM $vm $vdPG = $nic | select -ExpandProperty NetworkName
  
  Get-VDPortgroup -Name $vdPG
  

• How to get the ID of a single data centre and the Cluster

  Hello

  We have a product we need get the detail of data centers, Clusters, the Esx host and all Virtual Machines of a Virtual Center. And keep it in sync with the VCenter. I use a thread that queries the VCenter every 5 minutes and retrieves the data.

  We use Java VI SDK 4.0 for this.

  At the present time I am able to read all the details using PropertyCollector. But once a data center is renowned for my application, it is similar to a fact that a data center with the old name has been deleted and a data center with the new name has been added. For this reason, when data center is renamed, I remove entities for the former my application Esx host and adding new features to the ESX hosts in new data center. It causes a lot of unwanted things.

  So, I want to go get some unique Id of the dataCenter and Cluster, so that when a cluster/datacenter is renamed, uniqueId is always the same and my app will be able to know that it is just a change of name. And entities for ESX/VirtualMachine will be kept.

  Please, help me to know the unique id of the cluster/datacenter.

  Thank you

  Deepak

  Yes, there are supposed to be unique UUID generated by vCenter or ESX (i) and if you have not manually mux with values. The UUID is guaranteed to be unique within a given instance of vCenter.

• Prepare disks for ASM (data files and FRA)

  I intend to place data files on a disc 1 (sd1) and disk2 (PSD) when the backup of files (FRA) on disk3 (SDC). Here's how I'd do:
  
  For data files
  Disk1 is divided into a single primary partition (with native Linux what ID 83 not formatted system)
  Disk2 is also divided into a single primary partition (with native Linux ID 83 system not formatted)
  
  oracleasm createdisk vol1/dev/sda1
  oracleasm createdisk vol2/dev/sdb1
  
  CREATE DISKGROUP DATA EXTERNAL vol1, vol2 REDUNDANCY;
  
  
  For backup FRA
  
  Disk3 is partitioned into four primary partitions: / Boot (ext3), / (ext3), swap (swap) and /u01 (ext3)
  
  The FRA will be put under the/U01 and then attend the ASM:
  
  oracleasm vol3/dev/sdc4 createdisk
  CREATE DISKGROUP DATA EXTERNAL vol3 REDUNDANCY;
  
  Now, the problem. (1) the/U01 has already be formatted in ext3; (2) Oracle (DBMS) software will also be place under/U01
  
  It will be a problem?
  
  
  Otherwise, I can put FRA on the same drive as the data files, i.e. on disk1 and disk2. In this case, I need to partition the disk 1 in two primary parititions sda1 and sda2 (native Linux system ID 83 not formatted), one for data files and another for FRA (do the same for disk2). The downside is that the data file and the file recovery will be on the same hard drive.
  
  
  Please offer some suggestions.
  
  
  Thank you
  
  Scott
  
  PS: in the environment of production, all the disc 1, 2 and 3 will be on hardware RAID 1.

  RAID 1 will protect you only a device failure. It won't protect you partition, the file damage system or user errors; It will be in the image of the errors and problems like any other data.

  So what happens if you delete by mistake / U01 or some other accident happens and you loose that partition? With your current setup, you will lose everything and will not be able to restore or recover the database. Put tablespaces FRA and DB on the same physical device is certainly a very bad idea, whether or not it is a RAID.

  ASM is not a software RAID 1 mirror. It ensures redundancy of data based on file extensions and knows about files of Oracle database, which is a very good thing. You probably do not want to specify 'external redundancy.

  In a production system, you'll certainly want to mux the critical data and to store the DB controlfiles, redo logs and finally archivelogs on media separate physically in order to avoid the single point of failures wherever possible. You can use partitions and volumes in ASM, but they should be separate physical drives, otherwise you will bypass the ASM data redundancy. You must also have a solid strategy for RMAN backup. The FRA is supposed to store backupsets RMAN, copies of the image, the important archivelogs and multiplexes of the copies of the database files and should therefore always on a separate physical disk.

  Unless you simply play, I strongly suggest that review you your current configuration.

• create a tablespace without specifying the path to the data file and the name

  Hello
  
  Is it possible to create a tablespace without specifying the name and the path of the data file.
  
  For example: just specify the name of the tablespace and the size of the data file, the data file must be created in a default location with the default name? Is this possible?

  The use of the files managed by Oracle
  Internally, Oracle uses standard file system interfaces to create and delete files if necessary for the following data structures:

  * Tablespaces
  * Online redo logs
  * Control of files

  Through initialization parameters, you specify the directory of file system to use for a particular file type.
  EXAMPLE:
  The following parameters are included in the initialization parameter file:

  DB_CREATE_FILE_DEST = ' / u01/oradata/sample.
  DB_CREATE_ONLINE_LOG_DEST_1 = "/ u02/oradata/sample.
  DB_CREATE_ONLINE_LOG_DEST_2 = ' / u03/oradata/sample.

  The following statement is issued at the SQL prompt:

  SQL > CREATE a DATABASE sample.
  SQL > CREATE TABLESPACE tbs_2 DATAFILE SIZE 400 M;
  SQL > CREATE UNDO TABLESPACE undotbs_1;

• Cannot see reverse data warehouses in the model

  Hi all
  
  I am trying to reverse both PeopleSoft custom defined in an Oracle database tables and bring them to ODI.
  However, even if the reversal of the process itself (standard and custom) doesn't give any errors, I can't see the data stores in the model.
  
  I connect to the Oracle database using a user id that is not sysadm. This user had only read access to the two tables and sys.dba_objects (initially, while doing a reversal on measure, it was an error which I understand that sys.dba_objects need to access) above.
  I am able to query and read data from tables using sql developer using this new user.
  
  I believe also that the topology has been set up properly and I could do a ping of the database by using the user successfully when you set the physical schema.
  
  Advice as to why I can't see data warehouses in the model even after the overwhelming success?
  Help any will be appreciated.
  
  Thanks in advance,
  Vivek

  Yes,

  The latter request must show any xxxx of the user table, and he did not.

  Take a look if the objects you need to reverse are not synonymous. If that's true, if they are public or private and the true owner of the table referenced by the synonym...

• No sound on DVD playback and the size can be reduced to half of its original size

  Hi, I have a few problems on my DVD player after you install the windows media player 11.
  No sound during playback and the size can be reduced to half of its original size.

  Can someone show me how to fix tat?

  Hello

  you have a codec pack and/or a DVD player separated installed on your system? If not, then try, because play DVD´s with MediaPlayer 11 is not very comfortable and
  you encounter errors, for example you have.

  I suggest you: download a codec pack (for example K-lite or something: http://www.free-codecs.com/download/Codec_Pack_All_in_1.htm) install it and maybe try to use another dvd as "Media Player Classic" player that plays almost every videofile/DVD/etc. that exist.

  For the third part of the applications that perform many tasks, I usually discover www.tucows.com and www.download.com.  They have a wide variety of programs, and the trick is to put in the correct search terms to find what you are looking for.  Make sure you that your selection is compatible with Windows Vista and at tucows, try to pick one with 4 or 5 cows because they are the highest rated.

• Use LR5. Because of volume and the size of the photos, I use an external hard drive. When opening LR5 it references only the local hard disk. How can I change the refernce to read the external drive. Thank you

  Use LR5, due to volume and the size of the photos, I use an external hard drive. LR refers only the Local Drive C not outside. Where do I change this by LR read the external drive. Grateful for the help.

  Thank you

  LR is not a file Explorer. He knows only the disks that you imported photos of.

  If you have previously imported these photos, then later moved into the external hard drive, go to the library files and "update location" Panel on the files that you moved.

  If you have never imported these images on the external hard drive, perform an import by using the option 'Add' (not ' copy') to keep the images on the external hard drive during import.
