Assistance with the scrip value perpetually bulk bookings using Get-ESXCLi

I was expecting a little help here. Ive written a script which must on a "Perpetually reserved" lun using Powercli & Get-ESXICli, however when I run the following command locally on a host computer to confirm it worked and LUN are marked respectively, I find that the result is False

esxli store feature list | grep reserved

Ive written script is below. IM aware there are easier ways to get the IDs and get hostnames, etc. However im more concerned about the actual action of the script in the creation of the reserve.

To set the flag on all ESXi nodes in a cluster, the script needs a little change

$vmName = "VMwithRDM"

$vm = Get-VM -Name $vmName$rdm = Get-HardDisk -DiskType rawPhysical -Vm $vm$vmhosts = Get-Cluster -VM $vm | Get-VMHostforeach($esx in $vmhosts){  $esxcli = Get-EsxCli -VMHost $esx  Get-HardDisk -DiskType rawPhysical -Vm $vm | %{    $esxcli.storage.core.device.list($rdm.ScsiCanonicalName) |    Select @{N="Time";E={"{0:g}" -f (Get-Date).TimeOfDay}},Device,IsPerenniallyReserved

    $esxcli.storage.core.device.setconfig($false,$rdm.ScsiCanonicalName,$true)

    $esxcli.storage.core.device.list($rdm.ScsiCanonicalName) |    Select @{N="Time";E={"{0:g}" -f (Get-Date).TimeOfDay}},Device,IsPerenniallyReserved  }}

The logic is now as follows:

  1. Get the ROW (s) physical connected to the virtual computer (if your RDM is virtual, you will need to change the DiskType, add them both to the setting)
  2. Get all nodes in ESXi cluster where the virtual machine is configured, and then run the codeblock to each node
    1. The current flag of the RDM LUN parameter list
    2. Change the flag
    3. The current flag of the RDM LUN parameter list

  • Updated with the hash values column

    Hi all

    I have a requirement to add a column to a table and fill it with the hash values. The table contains an xml column and hash value of this column need to be filled to newly added column. I think that the ora_hash function will not support the xml type column. Just tested with the following script and it works.

    update TBL_COMPONENT_XSL set hash_val = ora_hash((SELECT TCX.COMPONENT_XSL.getStringVal() FROM TBL_COMPONENT_XSL TCX where rownum =1));
    

    can you please suggest me how to fill the column with the hash values.

    SQL> desc TBL_COMPONENT_XSL

    What happens if you try with:

    update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getStringVal ());

    update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getClobVal ());

  • update to column values (false) in a copy of the same table with the correct values

    Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.

    My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:


    Update mnt.workorders
    Set approvalstat = (select b.approvalstat
    mnt.workorders a, mnt.workorders_copy b
    where a.workordersoi = b.workordersoi)
    where exists (select *)
    mnt.workorders a, mnt.workorders_copy b
    where a.workordersoi = b.workordersoi)

    It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.

    Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:

    Update (select a.comappstat, b.comappstat
    mnt.workorders a, mnt.workorders_copy b
    where a.workordersoi = b.workordersoi - this is a PK column
    and a.comappstat! = b.comappstat)
    Set b.comappstat = a.comappstat

    Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:

    Update mnt.workorders_copy
    Set comappstat = (select distinct)
    a.comappstat
    mnt.workorders a, mnt.workorders_copy b
    where a.workordersoi = b.workordersoi
    and a.comappstat! = b.comappstat)
    where a.comappstat! = b.comappstat
    and a.workordersoi = b.workordersoi

    The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :

    ERROR on line 8:
    ORA-00904: "B". "" WORKORDERSOI ": invalid identifier

    First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)

    Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?

    I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.

    Thank you

    Hello

    First of all, after post 79, you need to know how to format your code.

    Your last request reads as follows:

    UPDATE
      mnt.workorders_copy
    SET
      comappstat =
      (
        SELECT DISTINCT
          a.comappstat
        FROM
          mnt.workorders a
        , mnt.workorders_copy b
        WHERE
          a.workordersoi    = b.workordersoi
          AND a.comappstat != b.comappstat
      )
    WHERE
      a.comappstat      != b.comappstat
      AND a.workordersoi = b.workordersoi
    

    This will not work for several reasons:
    The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
    There is no link between the mnt.workorders_copy and the the update and the request of void.

    If you do this you should have something like this:

    UPDATE
      mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
    SET
      A.comappstat =
      (
        SELECT
          B.comappstat
        FROM
          mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
        WHERE
          a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
          AND a.comappstat != b.comappstat
      )
    WHERE
      EXISTS
      (
        SELECT
          B.comappstat
        FROM
          mnt.workorders_copy B
        WHERE
          a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
          AND a.comappstat != b.comappstat
      )
    

    Speed is not so good that you run the query to sub for each row in mnt.workorders
    Note it is condition in where. You need other wise, you will update the unchanged to null values.

    I wouold do it like this:

    UPDATE
      (
        SELECT
          A.workordersoi
          ,A.comappstat
          ,B.comappstat           comappstat_OLD
    
        FROM
          mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
          ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
    
        WHERE
          a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
          AND a.comappstat != b.comappstat
      ) C
    
    SET
      C.comappstat = comappstat_OLD
    ;
    

    This way you can test the subquery first and know exectly what will be updated.
    This was not a sub query that is executed for each line preformance should be better.

    Kind regards

    Hello

    1. which edition of Windows are you using? Is - this edition is 32-bit or 64-bit?
     
     
    Given that the game is compatible with Windows 7, I suspect that the conflict can be 32-bit or 64-bit architecture.
    The link below shows the compatibility of this game with Windows 7.
     
     
    Method 1.
    We must ensure that the edition of the game must correspond with the operating system.
    If you use 64-bit in this game, you need the 64-bit Windows to install it.

  • I'm trying to access a wireless network with the password provided for me. I get the following error message

    I'm trying to access a wireless network with the password provided for me. I get the following error message: "the network password needs to be 40bits or 104bits depending on your network configuration. This can be entered as 5 or 13 characters ascii or hexadecimal 10 or 26. "what does this error message mean and how do I address so that I can access the wireless network?

    I use XP Professional with service pack 3. I get this error message every other time I try to log in to a protected wireless network security. I used to not get this message; but, now, it may be impossible, sometimes to call all wireless providers when I might only need for a short period or after hours service opening.

    In addition, it is my computer that requires the network password to be different, not the provider of wireless. A password is given to me who works for other users, but my computer won't let me use it.

  • virus: I struggled with the virus for some time and cannot get rid of them

    I have struggled with the virus for some time and cannot get rid of them. I bought a few programs, but they have also been infected. any suggestions for a really good virus buster.

    Hello

    First of all, an antivirus solution to an already infected system of loading is usually pretty useless. The bug will block all attempts to remove or load what it sees as a threat. Second, without knowing which virus you are affected by, it is difficult to be precise.

    You can take action include:

    (a) work in safe mode, there is much less likely that the virus is able to load and resist actively.

    (b) the safe mode, run utilities malwarebytes.org and AV solution that was installed * before * your infection.

    (c) post is back with a better description of what is on your system to learn more targeted advice.
