• Policy path defined LUN

  We are doing a migration of SAN and therefore affect all current LUN MRU. Currently some of the paths are fixed and accompany the round robin, according to the SAN LUN device. As all storage hosts will now be on one device I need a script to set policies to MRU. Would this work?

  SE connect-VIServer-Server X - X user - password X

  {foreach ($hostx in get-vmhost)

  $hostview = get-views $hostx

  $storageSystem = get - see $hostview. ConfigManager.StorageSystem

  $policy = new-object VMware.Vim.HostMultipathInfoLogicalUnitPolicy

  $policy.policy = "MostRecentlyUsed".

  $storageSystem.StorageDeviceInfo.MultipathInfo.lun | foreach {$storageSystem.SetMultipathLunPolicy ($_.ID, $policy)}

  }

  It works, but why not use the cmdlet Set-ScsiLun with the parameter - MultipathPolicy.

  Get-VMHost | %{
    $_ | Get-ScsiLun -LunType Disk | Set-ScsiLun -MultipathPolicy "MostRecentlyUsed"
  }

• Change of MSCS RDM disk offline after VMware Server or patching firmware finishing or multi path IOPS / s - SQL MSCS RDM disk

  Hello

  Yesterday, we installed a fifth ESXi host at our development center and along that we also had a window of maintenance for other hosts.

  We made:

  • HP Proliant HP Service Pack upgrade to 2014.06.0_784915_001. We have HP BL460c Gen8 servers. The old PSP performed from September 2013
  • Installed patches for ESXi 5.1 U1, the latest 10-15 patches since February. Do not install 5.1 U2.
  • Upgrade VMware Tools on virtual machines.
  • Changed multi path IOPS / s for HP 3PAR from 100 to 1. (esxcli storage nmp ATAS add s "VMW_SATP_ALUA' Pei"VMW_PSP_RR"- IOPS O / s = 1 - c"tpgs_on"v '3PARdata' - M 'VV' EI 'HP 3PAR Custom iSCSI/FC/FCoE ALUA rule')

  After this interview little MSCS SQL cluster stopped working. It does not start because it cannot access the drive. I can see the drive in disk management, but they are all in an offline mode. Can't do anything about them, except a single disc. This one is online!

  Did anyone here have no idea what on Earth is wrong? If I does not tomorrow I have to list a species of Microsoft or VMware. I have not tried to remove/add the RDM-disc.

  Windows 2008 x 64 Enterprise

  SQL 2008 R2

  ESXi 5.1 U1 (latest patches)

  Thank you!

  Finally solved with assistance from HP support.

  Solved this KB KB VMware: change a LUN to use a policy different selection of the path (PSP)

  The "funny", it is that the cluster has been around for 4-5 years and works on EVA SAN and now 3PAR with RR as a policy path, and all of a sudden it stopped working. Perhaps a host profile political trigged in, I don't know. And I could also see and access 5/6 disks, why not 6? And was on the way from RR.

  I asked HP about this.

  Thank you for all your help.

• How to Access Manager for devices in the Windows 7 Ultimate Computer of the Microsoft Management Console (mmc) or Windows XP Professional computer using the computer (compmgmt.msc) management?

  I want to access Device Manager on a Windows 7 Ultimate remote computer from a computer running Windows XP Professional.  Whenever I have use (compmgmt.msc) computer management and access the remote computer, I connect successfully to it.  But when I select the Device Manager it says: 'access denied '.  I checked the security policy (secpol.msc) and I chose the deny access to this computer from the network and there no users and groups listed but it says that its default value is invited.  Can you tell me the step by step procedure?

  Thank you.

  In addition to changes to the GP, you must also do the following.

• Multichannel policy statement

  Hello

  I use a script to get strategy multichannel for guests. What I need is a way so he could send me the report when it is in place. The problem is that it should report only on warehouses of data/hosts who do not conform.

  Example: (if we check for hosts who have a policy path defined as round robin report should have all the hosts that are against this rule - fixed/mru)

  $Hosts = get-Cluster cluster-name | Get-VMHost | Name sort

  {ForEach ($VMHost in $Hosts)

  $ScsiLunsInfo = $VMHost | Get-ScsiLun LunType - drive
  {ForEach ($ScsiLun to $ScsiLunsInfo)
  $PathPolicy = (get-ScsiLun CanonicalName - $ScsiLun - VmHost $VMHost). MultipathPolicy

  Logical #The is required in this case to display all hosts which have a policy of fixed/mru path. The format of CSV file should have something like "PathPolicy".

  "# of $ScsiLun on $VMHost is $PathPolicy.

  If ($PathPolicy - don't "RoundRobin") {}

  Export-csv "C:\somefile.csv".

  }}}

  THX,
  A

  This is the additional code, I wanted to say in my post in the previous post.

  One way to resolve this might be something like this

  $Report = @()
  
  $esx = Get-Cluster MyCluster | Get-VMHost| Sort Name ForEach ($VMHost in $esx) {
      $record = Get-ScsiLun -VmHost $VMHost -LunType disk |      where {$_.MultiPathPolicy -ne "RoundRobin"} |      select @{N="VMHost";E={$VMHost.Name}},CanonicalName,MultiPathPolicy    if($record){
        $Report += $record    }
  }
  if($Report){
    $Report | Export-Csv "C:\somefile.csv" -NoTypeInformation -UseCulture}
  

  In this case, there is no CSV file created when all LUNS have RoundRobin

  Hi Surya,

  No, it's not any problem with the configuration of your path.

  It only means that this policy does not allow additional configuration.

  I.e. with fixed NMP, you would be able to configure a preferred path allowing you to manually distribute the i/o load.

  Your current configuration does not offer this option.

  Kind regards

• Best practices for managing strategies of path

  Hello

  I get conflicting advice on best practices for managed paths.

  We are on version 4.0 of ESXi connection to a HP EVA8000. Best practices guide HP recommends setting the strategy of railways handle on Round Robin.

  This seems to give two active paths to the optimized controller. See: http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA1-2185ENW.pdf

  We used certain consultants and they say that the best practices of Vmware for this solution is to use the MRU policy which translates a single path to the optimized controller.

  So, any idea what good practice is best practice? Does make a difference?

  TIA

  Rob.

  Always go with the recommendation of the storage provider.  VMware recommendation is based on the characteristics of the generic array (controller, capable ALUA failover methods, etc.).  The storage provider's recommendation is based on their performance and compatibility testing.  You may want to review their recommendations carefully, however, to ensure that each point is what you want.

  With the 8000, I ran with Round-Robin.  This is the option of creating more robust paths available to you from a failover and performance point of view and can provide performance more even through the ports on the storage controller.

  While I did of the specific tests/validation, the last time that I looked at the docs, the configuration of HP recommends that you configure each IO to the ports in the switch configuration.  This adds the charge to the ESX host, the switch to other ports, but HP claims that their tests showed that it is the optimal configuration.  It was the only parameter I wondered in their recommendation.

  If you haven't done so already, be sure to download the HP doc on configuring ESX and EVA bays.  There are several parameters that you must configure the policy path, as well as a few scripts to help make the changes.

  Virtualization of happy!

• Location of the table "Data store path Selection" database and input valid value for the Round Robin

  Long history, work paths peripheral to the equivalent of "Round Robin" (VMware) programmictally change as seen in vCenter - Volume Properties-> manage-> trace selection policy paths.

  Struggling to get the value to change through scripts. Think that it requires the value as expected in the datamodel vcenter. Find it by inspecting the paintings have not yet

  Thanks in advance

  The values on the parameter - MultipathPolicy are: fixed, MostRecentlyUsed, RoundRobin, unknown

  This changes all policies to roundrobin on a specific host

• Removable storage access is denied

  Hello world

  Before my question, I'm not 100% sure that it is related to Windows 7 or Windows Server. Please let me know if I'm wrong.

  A few weeks ago I had to block access to all classes of removable storage to a group of 5 users or more in the company. So I used the "Computer Configuration" GPO (Computer Configuration > administrative templates > system > removable storage access > classes all removable storage: deny access for all 'Active'.) I applied it to the users, and it worked fine. From there, they were able to use the key USB, CD, etc... After awhile, it was decided by the administration they could get access to rear. So I removed the GPO of these users. After some time, users are complaining that access was denied again. From there on, here's my resolve the path

  • I did a GPRESULT and I could see that the GPO has been applied.
  • I looked to the top of local computer policy (gpedit.msc) and this setting is not configured
  • I looked upward in the event viewer in the computers and the domain controller, nothing interesting found
  • I tried to make a GPUPDATE/force and restart
  • I tried to remove the computer from the Active Directory and join it back to the field
  • The GPO still exists, but not applied to users having the problem, I tried with 2 computers of third parties to reproduce the problem. I applied the GPO, denied access to all removable storage classes. I délettrée the GPO and access to all removable storage classes to restore.

  At this point, I don't know what to do. It has been a little hours (days) now that I searched on the internet about this problem and the only user I found that solved this problem, solved by formatting computers upward... This isn't the solution, I want to use.

  Please note that these users are in a connected remote site MPLS to the main site and there is a DC in each site and also the replication works very well.

  Best regards

  Mike

• How do I completely disable the automatic encryption of files on XP

  I have Windows XP SP3 and I download all of the files are automatically encrypted any directory I save the download in. It is not that simple that disabling the encryption of any specific directory, the file will be downloaded as encrypted regardless of whether the directory is encrypted or not.

  I think that there is a group policy or other parameter which not only puts everything in My Documents to encrypted, but also everything I download, no matter where it is downloaded. It didn't matter whether the folder is encrypted, or even on my C: drive: a downloaded file is always encrypted. It is a problem if I want to move the file to another computer.

  Is there a policy or a setting somewhere to turn off the automatic encryption of the registry?

  Additional information:

  In my registry, I found the following keys:

  HKEY_CURRENT_USER\Software\Microsoft\Cryptography\AutoEnrollment

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\AutoEnrollment

  And many other key under

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography

  HKEY_CURRENT_USER\Software\Microsoft\Cryptography\CertificateTemplateCache

  HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\EFS\CurrentKeys

  There is no button on EFS in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion

  There is no policy defined in Group Policy (gpedit.msc)

  Computer Configuration / Windows Settings / Security Settings / public key policies / EFS file system

  The Microsoft KB article in the "More information" section describes an EFSConfiguration setting that, when the '1' value, disables EFS of the registry.

  "EFS can not be activated supposed after disabling this policy and strategy disable EFS.

• Terminologies of storage very important for VCAP-DCD

  I have compiled this post from different positions (Duncan Epping), passionate about Valentin Vipin vExpert, vmware KB, etc. So the stock of credit goes to them.

  I think this post will help the VCAP-DCD candidates for Design elements and objects of drag-and - drop.

  VMware has introduced a new architecture for vsphere storage called PSA (Pluggable Storage Architecture). This architecture using plug-ins. This (PSA) is simply the name of the new concept.

  Let's start with the native plugins of VMware.

  The Multipathing (NMP) Native is the default module that uses ESX (from vSphere). It contains the two ATAS (storage array of plug-in type) and PSP (plugin path selection) plug-ins.

  If your table is listed in the hardware compatibility list, VMware ESXi decided before (with the help of plugins PSP: VMW_PSP_FIXED VMW_PSP_MRU, VMW_PSP_RR) what paths multiple "algorithm" will be used. ESX will do natively: fixed, MRU, Round-Robin.

  Note: * native vmware Multipathing algorithm = > fixed, MRU, Round-Robin *.

  The NMP uses rules to decide who will serve as a storage array Type Plugin (ATAS) and Plugin access path selection (PSP) will be used. If you want to change these rules you can use 'esxcli' and you can find the rules in the "/ etc/vmware/esx.conf". For example the default PSP for the Bay EMC Symmetrix is fixed:

  / Storage/plugin/NMP/config [VMW_SATP_SYMM] / defaultpsp = 'VMW_PSP_FIXED.

  What does ATAS?

  The ATAS manages path fail-over, it's as simple as that. This of course will be reported back to the NMP, because the NMP is responsible to ensure a flow of e/s. The ATAS will monitor the health of a path and take the necessary steps according to the type of array. Nothing more, nothing less.

  What does the PSP?

  PSP determines which path will be used for a request of e/s, in other words the PSP addresses fixed, MRU and Round-Robin algorithm.

  Keep in mind that the type of the PSP that will be used has already been preconfigured, it's not the PSP who decides that if she will be fixed or MRU, it's the NMP which decides this based on predefined rules above.

  MPP

  What's next? It would be a Plugin (MPP) of multiple paths. VMware NMP is built by vmware, on the other hand MPP is developed by sellers of paintings. EMC is one of the suppliers who have already demonstrated their MP. Example: EMC MPP is known as Powerpath for ESX.

  -------------------------------------------------------------------------------------------------

  Different types of storage and Multipathing policy:

  Assets:-the storage system have two controllers and LUN (virtual disk or storage device) are accessible or host can perform i/o via the two controllers.

  Active-passive:-host may have I/O to and from a unit number logic via a controller only (through active controller-owner - of the LUN and not through the other)

  ALUA:-asymmetric Logic Unit Access is where the storage system simulates the function of assets (unit number logic is accessible via two controllers but alone will be the owner of it)

  Example: EMC VNX 5300 is not really active/active table. It just a group of asymmetric access logical unit.

  For this reason that ESX detect this EMC VNX 5300 as a storage ALUA and plug-in uses ATAS VMW_SATP_ALUA_CX.

  If a storage system is active/active, active/passive or ALUA, vmware PSP may be FIXED, SRM or RR based on array type. The general rule is:

  1. for an active-passive array, you will need to define the strategy of path (PSP) "most recently used". (The default PSP for active/passive storage devices is VMW_PSP_MRU). There is no path parameter with the MRU policy.

  2. an active-active array should have the policy path set to "fixed". (The default PSP for active storage devices is VMW_PSP_FIXED).

  Important: VMware does not recommend that you use VMW_PSP_FIXED for devices (table) that have the VMW_SATP_ALUA storage array type strategy assigned to them. This is because (according to my understanding) ALUA is not really active/active storage, so in this case, VMW_PSP_MRU should be used.

  3. for both active/active and active/passive array, we can choose "round robin (RR).

  The host uses an automatic path selection algorithm that runs through all Active paths connecting to arrays of active-passive, or through all the available paths connecting to the active tables. Automatic path selection implements through the physical paths available to your host for load balancing. Load Balancing is the process of spreading the i/o requests on the paths. The goal is to optimize the performance of flow as I/O per second, megabits per second, or response time.

  VMW_PSP_RR is the default value for a number of tables and can be used with both active-active and active-passive arrays to implement balancing on different paths LUN.

  Thus, the rule is to have chosen the PSP to the different array type:

  For active/active - FIXED, RR table

  For RR table - MRU, active/passive

  For ALUA table (which is really a simulated table not really active/active, active/active)-MRU, RR

  When storing ALUA, vmware SRM is also optimized / non optimized paths into account.

  So in the case of a previous path optimized operation, I/O is shifted to the optimized path (which previously used before a failover to a path not optimized)

  MRU switches to a different path when one of the following codes, meaning SCSI NOT_READY, ILLEGAL_REQUEST, NO_CONNECT and SP_HUNG are received from the table. Remember that MRU is not failback.

  For active/active SAN, the policy path sets a single failover occurs when detection SCSI 'NO_CONNECT' code is received from the table. When the path back a return will happen.

  As you can see, four against a single SCSI sense code. You can imagine what happens if you change MRU Fixed when it is not supported by the table. SCSI sense codes will be sent to the table, but ESX is not expected (NOT_READY, ILLEGAL_REQUEST, SP_HUNG) and a path will tilt.

  Great write!

  With regard to the PSP where it can be MRU or RR it is VERY important on review DCD that pay you close attention to the what the requirements are and what the instructions tell you to do.

  Other then that, great work to consolidate this information

• Should we use FIX or RR for ALUA storage array?

  We have activated just ALUA on the CX4-240 storage array.

  After the restart ESXi hosts, the policy path is set to fixed.  Need to change us to Round Robin?

  Your opinion is requested.

  Thank you

  Hello

  As mentioned earlier, Vmware HCL says that you can make the VMW_PSP_FIXED

  http://www.vmware.com/resources/compatibility/detail.php?deviceCategory=san&productid=4427&deviceCategory=san&partner=30&keyword=cx4%20240&isSVA=1&page=1&display_interval=10&sortColumn=Partner&sortOrder=Asc.So if you would like to switch to RR,you have to check with EMC to know its Supported path policy. Since your FLARE code is 29, it would be good if you can get updated (Flare 30) after confirmation by EMC.
