Anyone know what is

$pEsxCli.storage.vmfs.unmap ($l, $pDS)#Run cancel the order mapping

$1 ???

Ideally, UNMAPBlockCount, that is say 60000 or more

I suspect it's $l (a variable called L 1 no), but I do not see where it is initialized in the script.

The parameter expects a value for recover unit, which is by default 200 (see KB2057513)

  • Cancel the MAPPING of Windows volumes?

    I don't know about scsi unmap command for vmfs recover space on a LUN EQ. Is there an equivalent for Windows data volumes connected via iscsi?

    Hello

    On Dell PS Series San, you must run EQL FW, 6.x or higher and the volume cannot be set up for EQL replication.  It is as well rep SYNC and async rep.

    Much depends on the version of Windows that you're talking about.  Windows 2008 R2 and do NOT naively support UNMAP.   It does support the SSD TRIM command.  However, if you install the printer Dell HIT / ME software he installs a driver to modify the order ADJUST order cancel the MAPPING on the fly to Dell PS volumes.   This applies to volumes that are DIRECTLY related to the EQL volume via the MS iSCSI host initiator.  A virtual machine on a VMFS partition is not supported by HIT / ME software.

    Windows 2K 8 and CSV de Hyper-V R2 volumes does not support UNMAP.  This is a MS issue, unrelated to the table.   Volumes Windows 2012 and R2 CSV can bear UNMAP only when you use virtual disks VHDX, if using the recovery of old VHD is not taken in charge.

    An additional advantage of HIT / ME in all cases taken in charge, is through the crib of Snapshot Auto GUI, you can force recovery anytime option.

    Note: If you are using snapshots, you can not immediately retrieve the expected amount of rear space.  The snapshot can always refer to this data, so until the snapshots that reference is deleted it will be allocated.

  • Cancel the mapping of space used Dell PS4100 SAN on the Windows Server 2008 R2 Hyper-V cluster.

    Is Dell has a tool to undo the mapping of used space of deleted VMS or data on the volume/LUN, the SAN from Dell does not give space automatically if you delete data. Volume/Lun is thick.

    You must install the HIT / ME tool and use the EqlReThin utility.  If you download the 'Dell EqualLogic Host Integration Tools for Microsoft Installation and user guide' on the support site, there is a description on how it works.

  • FW 6.0 EPA, cancel the SyncRep and MAP

    Nashua dear gurus,.

    I just EPA 6.0 FW and read the group administration Guide. This stipulates that it s recommended do NOT enable undo the SCSI MAPPING with ESXi 5 If you are using the standard replication. I understand that, because it could cause huge amounts of replication. Now, my question would be: this recommendation is part when using SYNCREP? I ask because with SyncRep EACH writing goes to the two pools, for example, if the SCSI UNMAP command is also a "write" command, it should NOT affect the SYNCREP in my understanding. Am I wrong?

    Best regards
    Joerg

    Since the v6 release notes: it goes the same for volumes of Rep SYNC, do not cancel the MAPPING.

    Munmap volumes and replicated

    It is not recommended to run the operations giving rise to SCSI unmap operations (for example, format or defrag) on the volumes on which the replication (including synchronous replication) is enabled.

    Such operations on replicated volumes lead zeros written in areas of destination of the volume. The writing of this article, of zeros can cause operations to take a long time to complete, and no space is reclaimed. As a result, Dell recommends you disable munmap on hosts or volumes (depending on the host operating system) that use replicated volumes. See the following sections for more information on deactivation and activation munmap in VMware ESX, Red Hat Enterprise Linux or Windows 8/Windows Server 2012 of operating systems.

I just want it to be as google map application. Where you seek and find information. Thank you.

    Hello

    A colleague has found the solution:

    Obtained with the client and tried to cancel the registration of services by changing the order of the switches on the controls even error.  Allowed to go out the DelService file and put the ID in it same error.

    Open until a new admin command prompt, listed services, selected code should be deleted ran a c:\oldid.txt Notepad to create a new file and placed the service ID in this and run the command and it worked.

    I tried another service using the strawberry of old files it renamed delservice.txt and got the error again.  Tried again, but renamed the file delser.txt error result.   Tried it with another file, the client had created called Del_Service.txt and got the error.

    Not sure what was with the formatting of the two files that the customer used, but just create a new file and put in the ID solved the problem. »

  • AF:dialog cancel the problem on the new line of VO

    With the help of 11.1.1.4.

    I have an af:popup that contains an af:dialog which itself contains entrable components mapped to attributes of VO, the first being an af:selectOneChoice (list of the part of the body). The list of the part of the body draws from a LOV configuration on the underlying VO attribute. LOV rowset is initialized in the model of the line layer whenever the popup is called to make sure that it contains all the allowed values.

    Everything works fine except when:

    (a) user adds a new row to the underlying VO and invokes the popup to initialize the values of the new line, and
    (b) the user selects a value in a list of the part of the body, and
    (c) user chooses to cancel the dialog box

    The PopupCanceledEvent triggers a Delete on the underlying VO in the case above operation, to remove the new line has been added.

    It all works very well, but if the dialog box is now called either for another new line or an existing line, the list of the part of the body indicates the value that has been selected to b) above and not on the value as it is in line with model (this has been verified). If I add and remove line using the Delete operation out of an icon above the table of VO (outside), then no problem. The problem is not correct itself unless / until the user goes in the new dialog box and completes the process of adding line by pressing the button of the OK dialog box. User can then delete this new line using the icon and then edit and add all operations work fine again.

    All about the model seems very well, the problem seems to be that the user interface components in the dialog box are not properly initialize values which I know to be in the model WHEN AND ONLY WHEN the dialog box was canceled on the addition of a new line (cancellation of a change does not cause the problem). I tried various RPP requests to try to synchronize the items with related values, but not luck.

    Does anyone have any suggestions as to what might be going on here?
