See Multipathing policy


How can I check the policy of Multipathing through all hosts on my cluster?

Take a look at 3 Re: multichannel policy statement  

Instead of making for all ESXi hosts in a cluster, you can just do a Get-VMHost to cover all ESXi hosts.

  • See Group Policy Persona does not

    Hello, wanted to begin test Persona display management, of what it looks like its not difficult to install, however I can't find the group policy, the Viewpm.adm.

    In accordance with the instructions, it will be in one of two places.  Either on the desktop from view after the Agent Install in C:\program VMware View\agent\bin

    or on the servers of connection in C:\program VMware View\server\extras\grouppolicyfiles

    The Viewpm.adm is not in these two places.  There is a v4v_desktopagent.adm, but it is not good policy.

    We run View Horizon Suite version 6.0

    Ive tried to install the last Agent to view one of the virtual machine is to see if that would install the Viewpm.adm, it didn't, and didn't manage Persona for the agent.

    Ive looked in other servers for it as well as our server composer\vcenter and security servers.

    I don't see a download of VMware for it.

    Something has changed with the release of version 6 and its in a different place?  Allocate instructions wheel I had version 5-oriented

    It doesn't seem like the VMW_PSP_FIXED_AP of the PSP, even if I can put it in the GUI. I'm under a Clariion CX4 and move to this policy rather than alternating repetition to get an automatic restore of LUN. Am I missing something? The script works fine if I use 'FIXED' but I want to use VMW_PSP_FIXED_AP for ALUA.

    Any help would be greatly appreciated. Thank you!

    OK, I see. In this case, you can use the Get-EsxCli cmdlet.

  • ESXi 5 - Set Roundrobin multipathing policy on all LUNS

    Hi all

    Does anyone know of an esxcli command to set the multi-channel management strategy on all THE storage of current and new data on a host to Roundrobin?

    We were able to do in ESXi 4 with the following command, but this no longer works in 5:

    Instead of

  • Is - this script PowerCLI obsolete?

    In an ESX 5.0 environment, I have a group of VMFS data store ten stores of data visible to a group of thirty-two guests. Each data store uses currently multipathing fixed to each host, but I want each data store instead use repetition alternated for all guests. I found the following on https://runningvm.wordpress.com/2010/08/31/vsphere-powercli-multipath-policy-script-examples/ ((troisieme paragraph):

    #Sets policy of multiple paths for all EMC LUNS (naa.6006*) connected to all hosts in the Cluster RV00 to roundrobin

    Get-Cluster RV00 | Get-VMHost | Get-ScsiLun - CanonicalName "naa.6006*" | Game-ScsiLun - MultipathPolicy "roundrobin".

    It promises to do exactly what I want, but page was published in 2010 and I fear it may be obsolete. Everything in this script still works in ESX 5.0?

    Also, can this little script to correctly run its own? Read further down the page linked sixth paragraph and following), I see the author offers a script plus much, much for implementing Multipathing to round robin, and makes me fear that this little one-liner may not be intended to stand on its own and can leave pieces untied and hid the consequences. Can someone comment on that?

    Thanks a ton, everyone!

    Yep, it should always work. I've actually used something similar earlier this week

    The plu script is just a bit more generic (i.e. you request credentials, clusters, etc.) and also defines the strategy of selection of the default path for the type of storage array. Maybe something to do for the new LUNS are configured correctly by default. It does not depend on the use of esxcli.exe, while you could do this with Get-ESXCli

  • 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

  • Political multichannel on ESX 4.1 and IBM XIV? What is recommended?

    Hello

    We are a little confused as to what the correct multi-channel strategy is when you have an IBM XIV storage.

    In September, we had a glance on the HCL and VMware has recommended the RR as policy for the XIV storage as you can see in the screen below (taken on 2010-09-23):

    2010-09-23.jpg

    But when we looked in the HCL yesterday VMware (2011-01-26) have changed to FIXED:

    2011-01-26.jpg

    And when we read the latest Redbook IBM reguarding this they recommend RR for ESX 4.x

    Page 225 at http://www.Redbooks.IBM.com/redpieces/PDFs/sg247904.PDF :

    With ESX Version 4 VMWare begins to support a policy of alternating for Multipathing
    production environments. Alternating Multipathing policy is always preferred to other
    choice when attaching to the IBM XIV storage system.

    So the main question is... What is the correct way to do this?

    I asked IBM and they have given me an answer yet, but they're looking for him because the didn't know why VMware has changed the HCL in this regard.

    BR

    Henrik

    Hi Henrik,

    The HCL to the IBM XIV has been updated to support a policy of path of the fixed (VMW_PSP_FIXED) or Round - Robin (VMW_PSP_RR).

    According to the Redbook - "alternate Multipathing policy is always best choice when attaching to system storage IBM XIV."

    I would recommend using Round-Robin, because it is the preferred option.

    Let me know if you have any other questions.

    Kind regards

  • HP Pavilion 550-055na: new disk will not install the new operating system

    Hello

    I bought a new HP Pavilion 550 - 055na with Windows 8 a month or two ago but want to use Windows 7. However, I decided that I will keep the hard, the PC came with, and have the option of Windows 8 in future if I want. So, I'm installing Windows 7 on a new hard drive.

    My problem is that the new copy of Windows 7 will not install on my new hard drive.  I get:

    Violation of secure boot

    Invalid signature detected. See the policy in the configuration of secure boot

    Then me to a black screen after I pressed Enter/Ok, who said the following.

    Check the presence of the media...

    Media present...

    On IPv4 PXE boot.

    If I press F12 on power on, I get a blue box asking me to select a boot device. The only options are:

    Realtek PCIe GBE Family Controller IPv4

    Realtek PCIe GBE Family Controller IPv6

    and the output by using the arrow keys

    How to change the secure boot strategy?  If I do, it means that I can install my 7 can I on my new hard drive? Also, providing that I do, I always will be able to use my Windows 8 OS drive after changing the secure boot strategy?

    Any help would be appreciated to greately.

  • How can I read firewire no port 1394 on my laptop.

    My computer laptop pavilion accepts all cards that could allow me to save data to tape DV camcorder from a camera with a fireware port.

    Hi Qsabe,

    Here is your Service Manual:

    HP Pavilion dv6 Entertainment PC - Maintenance and Service of Guide

    Look on Page 17.  See #10 - that slot on top of the extreme right, to the left of your laptop?  It is what we call an Express Card slot, it carries cards "54mm.

    Map Ronald described in his Post is:

    FireWire 800 Expresscard - 2 port 1394 b 9-pin to 6-pin

    It is another source for the product described, this one is by SIIG:

    http://www.ProVantage.com/SIIG-NN-ec2812-S2~7SII2085.htm

    The square box little covered on your laptop (on that same left side) is the small 1394 connector that could have been bought as an option.

    Which one??

    The truth is that you can probably use either the map OR the single cable converter.  Other opinions, it's your money and unless your DV camcorder manual warns you specifically for or against a certain type of material, then you can make your own decision.  Read your manual - go online and read what it says if you don't have a paper copy.

    Buyer beware:

    See return policy your store before you buy if you can pick up something if you can't use it for some reason any.

    Check it out:

    Go to the website of ProAdvantiage (above) and discover the SIIG device.  Find out what makes the device and why it is a good choice.

    My experience:

    I have a single USB converter 1394 cable that I use on a very expensive Sony HD camera / VCR and it works very well.  I'm not a professional photographer.

    Look at your manual.  See what he says and what you have on your machine.

    Google more information.  Make your choice.
