VmHost Script to change the MTU on vSwitch loop problem

• Script to change the settings for security vSwith

  We need a script to change the settings for security vSwitch.

  To change the below: -.

  Mac changes Accept Reject

  Forged pass Accept Reject

  The two parameters above must change on all the vSwitch in vcenter.

  Altogether. Pass an argument to Get-VMHost

  If you pass the complete hostname (as he shows in vCenter), it will act on the single host:

  Get-VMHost MYESXi01.mydomain.com

  or if you want to do more, you can pass a joker:

  Get-VMHost MYESXi*.mydomain .com

  FWIW, I think that should do the same thing on a single line, if you like this better

  Get-VMhost|%{$hv=Get-View $_.ID;$ns=$hv.ConfigManager.NetworkSystem;($hv.Config.Network.Vswitch)|%{$vs=$_.Spec;$vs.Policy.Security.AllowPromiscuous=$false;$vs.Policy.Security.ForgedTransmits=$false; $vs.Policy.Security.MacChanges=$false;$ns.UpdateVirtualSwitch($_.Name,$vs)}}

  Can someone please suggest to me how to fix the script for my v3.2.0 PowerGUI IDE can work with the latest PowerCLI in my computer laptop 64 bit Windows 7?

  Thank you.

  And I just tried with PowerGui (same versions of PowerGUI and PowerCLI you use), no problem.

  Must be something local on your desktop.

  Maybe try a uninstall/reinstall of PowerGUI?

• Script to change the subnet and vlan.

  Hello

  Please can anyone help with a script to change the subnet and VLANs on all the esx host in a cluster for the vmotion and management network interface?

  Thank you

  Astra

  I guess it worked because you pasted an out front, so:

  Get-Cluster mycluster. Get-VMHost | Get-VMHostNetworkAdapter | where {$_.} PortGroupName - eq "VMotion"} | {} %
  Game-VMHostNetworkAdapter - VirtualNic $_ - IP $_. IP - subnet mask "255.255.254.0" - confirm: $false
  }

  I guess that makes still out:

  Get-Cluster mycluster. Get-VMHost | Get-VMHostNetworkAdapter | where {$_.} PortGroupName - eq "VMotion"}

  2 vmknis right?

  If Yes, then it should work I think.

• How can I change the MTU in Windows 7?

  I need to change the MTU in 1458 to work with my router.

  You can try this...

• script to change the data type of column

  Hi gurus of the oracle.

  I have 190 tables in my database.

  I have the column type CHAR of all these tables data.

  I need to change the data type of CHAR in VARCHAR2 for all these tables...

  There the script to change the data type of all tables at once?

  Please help me in this regard.

  Thanks in advance

  Concerning

  REDA

  Hello

  There is nothing built-in to Oracle SQL to do.  Maybe your front-end has certain characteristics.

  You can write dynamic SQL statements to do.  In other words, you can write a query that the output is a SQL script like this:

  ALTER TABLE TABLE_A CHANGE (A_TXT1 VARCHAR2 (5))

  A_TXT2 VARCHAR2 (10));

  ALTER TABLE TABLE_B CHANGE (B_TXT1 VARCHAR2 (5));

  with one row for each column of type CHAR.  Notice how the first line of output for each table begins with ALTER TABLE... but the later lines at the same table.  Similarly, the last line of a table (which will be the same as the first row, if the table has only one column of type CHAR) to end with a semicolon, but other lines are not.

  Here's a way to generate and execute such a dynamic script in SQL * more:

  -Disable the features that make the output easy to read, but hinder the execution
  SET FEEDBACK OFF
  SET LINESIZE 500
  SET PAGESIZE 0

  -Create fix_char.sql
  COIL c:\some_pathename\fix_char.sql

  SELECT THE CHECK BOX
  WHEN ROW_NUMBER () OVER (PARTITION BY table_name
  ORDER BY column_name
  )  = 1
  THEN 'ALTER TABLE ' | table-name
  || "CHANGE (").
  ELSE «»
  END
  ||        column_name
  ||        "VARCHAR2 (').
  ||        DATA_LENGTH
  ||        ')'
  ||        CASE
  WHEN ROW_NUMBER () OVER (PARTITION BY table_name
  ORDER BY column_name DESC
  )  = 1
  THEN '); "
  Output END AS
  Of user_tab_columns
  WHERE data_type = "CHAR".
  ORDER BY table_name
  column_name
  ;

  SPOOL OFF

  -Turn on the features that make the output easy to read, but hinder the execution
  SET FEEDBACK ON
  SET LINESIZE 80
  SET PAGESIZE 50

  -Fix_char.sql performance
  @c:\some_pathname\fix_char

  It's good to change all the CHARIOT of VARCHAR2 columns.  The CHAR data type is nothing trouble.

• Script to change the name of the file to the virtual machine and its associated files

  Hello

  I'm looking for a script to change the name of the virtual machine in virtual center and also change it has associated file names in the data store to match file name of virtual machine. But the vmdk file will contain a descriptor which maps the - flat.vmdk file. So not sure that we can achieve this through a script.

  Thanks in advance!

  Not really as much as I know.

  The advantage of the svMotion is renamed it the files (.) VMX, VMDK,...) For you.

  The only alternative would be the command line. See Duncan Howto: renaming a virtual computer.

  With the help of the plink.exe tool which could possibly be scripted.

  Parargaph Style #0 is [No Style], and you cannot change this way. Simply start your loop at 1.

• Jumbo frames, change the MTU size without VM guest tension

  I'm trying to disable jumbo frames, specifically to change the size of the mtu to 1500 (instead of 9000) in vcenter on some hosts. Some hosts run esxi 4.1, others are running esxi 5.0. I wonder if it is absolutely necessary to turn off the virtual machines that are connected to the iscsi san network while making this change, or is it relatively safe to make this change, while VMS are running.

  Each VM has active multipathing, 2 vswitches with 1 NIC associated with each.

  I know how to make the changes, regarding my questions whether it is possible to safely make changes while VMS still access the SAN.

  Yes, it is something that I do in my lab quite frequently without using maintenance mode. Memaad notes, maintenance mode is always preferable to avoid unnecessary risks, but it's finally to you.

  See you soon.

• Change the MTU size to vmkernels on dvSwitch

  Hi all

  I have about 40 ESX hosts that belong to dvswitches different 6 and 6 different groups. Each host has 6 vmknics created for the dvswitch and all have value mtu of 1500. Can someone help me with a cli script to change all vmks 9000 MTU?

  Please let me know if additional information is required

  Thanks in advance.

  Try it like this.

  $MtuSize = 9000
  foreach($dvSw in (Get-VirtualSwitch -Distributed -Datacenter MyDC)){
    $dvSw.ExtensionData.Config.Host | %{
      $esx = Get-View $_.Config.Host    foreach($pnic in $_.Config.Backing.PnicSpec){
        $netSys = Get-View $esx.configManager.networkSystem      foreach($vnic in $netSys.NetworkConfig.Vnic | where {$_.Spec.DistributedVirtualPort}){
          $spec = [VMware.Vim.HostVirtualNicSpec]$vnic.spec        $spec.mtu = $MTUSize        $netSys.UpdateVirtualNic($vnic.Device,$spec)
        }
      }
    }
  }
  

  It will update the MTU value of each vnic connected to a dvSwitch
