vCSA and connection VNXe3100 LUN failed

Hi guys, how are you?

I got a problem here. Let me say the scenario:

I have a VNXe3100 LUN iSCSI-exporter. The export process are all conducted in the storage interface. We got a single ESXi host that accepts the LUN, it goes up and everything runs smoothly.

But when I'm building a clustered with two ESXi environment and the vCSA, the is working properly. When you deliver the LUNS, the vmhab is the storage, the path become active and the LUN is in operational condition mounted, but the data store is not mounted. Even using the storage... Add ability to add manually storage fails.

I think this could be a problem of vCSA, because with isolated hosts, everything works.

Does anyone have any idea?

Storage: VNXe3100

Method: iSCSI

Host: ESXi 5.5.0 Update2

vCSA: 5.5.0.20200 build 2183109

See you soon!

Found the answer! Fair value size MTU of the VDS 9000, where it was just in the vmk.

Thanks anyway!

  • For some reason, I can't get my Outlook Express to send my emails... they do not connect or send failed

    For some reason, I can't get my Outlook Express to send my emails... they do not connect or send failed... what I am doing wrong to cause this... I have used Outlook Express in the past and had no problem with it... Also, how can I know what e-mail programs POP3 or request the program Outlook Express? Could you please clarify this for me, thanks...

    I use Windows Live Mail as my regular e-mail address... but I can use a different e-mail to another e-mail program to configure Outlook Express?

    Visit the website of your email provider and see if they have instructions to set up an account in Outlook Express.  They provide you with the appropriate settings.   Nobody here knows them, because they are specific to the e-mail provider.  So check with your provider of messaging on the correct settings to use for OE.

  • Masking vs. zoning for UCS and NetApp storage LUNS

    I know it's more a matter of Cisco MDS/storage, but nobody knows masking the LUNS and zoning, which one would be the most preferred method? I have two switches Cisco fabric 9148, two controllers SAN Netapp FAS3210 1 UCS chassis with 4 blades B200 M2. I said that I should not connect the Cisco UCS fabric interconnect directly at the back of the NetApp SAN and configure with LUN masking, but I rather configure a fabric zoning on switches Cisco 9148 MDS. Normally, this wouldn't be a problem but we have an offsite location where we have not all DMS switches to, and I would like to connect them directly to the San.

    I was told that this could lead to corruption if misconfigured dsik and point of view of Cisco is to use a zoning by some type of switch Cisco Fabric. Of course, I have of course this Cisco advises anyone to manage this type of configuration through their facilities instead of on the SAN. Does anyone have an opinion on the matter?

    Zoning and masking are two completely different characteristics.

    Zoning occurs on your storage switches and is the equivalent of an ACL (Access Control List).  It limits who may be considering other targets and/or initiators.  (Who I see?)

    Occurs on your storage array and masking limits what initiator LUN has access to.  (What do I see?)

    * UCS is not supported to directly connect a storage array in the interconnection of fabric, at least to have a storage upstream switch (MDS or equivalent) to push the zoning.  The use of zoning prevents a faulty initiator potentially impacting on the operation of the others by limiting what they can see in the fabric.

    If you happen to have a Nexus 5 K by chance, they can also work as your storage switch.  The N5K is able to perform almost all of the same services as MDS fabric and is fully supported.

    Kind regards

    downloading acrobat adobe pro DC, it stops at 5% and bed WebGet request failed. And yes I am connected to internet when downloading and it seems that I have the system requirements for the download.

    I had this problem too on an area of PC, but when you sign on and the local administrator on this PC account, I was able to download it completely. You can connect to the account a local administrator on your PC or have your it Department do for you and see if it works.

In addition, run the installer as administrator by right click and choose "run as Administrator". Let me know if it helps you.

  • Satellite L650 Wireless disconnects and connection cannot be retrieved

    Hello everyone,

    I have a connectivity problem with my 3 year old Satellite L650, Windows 7...

    I have a LAN wireless in my house, so that my laptop will automatically connect at startup, without any problem.
    After some time (it can be minutes or hours) it loses signal and disconnects.

    This isn't a real problem, because the router is quite far from here, with walls between which can reduce the signal, so no surprises.
    But I can't reconnect later: connection status icon stops working.

    I mean it shows the image corresponding to "available wifi connections" or "connected but no internet access, but or by clicking on the icon or move the cursor of the mouse on it gives no output... it is responseless, and I can't connect to my wifi or any other wireless network.

    I tried to do it from the control panel - network and sharing Center, but the story is the same, the two "set up a new connection or network" and "connect to a network" is not responding when you click on it.
    The only way to connect is to restart the pc.

    How can I solve this?

    Any suggestion is appreciated,
    Thank you!

    > The only way to connect is to restart the pc.
    In case this question is repeated once again, try to refresh and renew the IP address.

    Go to the console (in the type of search CMD)
    Now use the command: ipconfig / renew

    After this attempt to connect to the Wlan again.

    In which case it would not be useful, I recommend you to change the settings of the router.
    I mean that you need to reset the router. Then, you need to test with different types of protection Wlan Wlan connectivity and other standard Wlan (802 11 B G or N)

    Test also the laptop with open WiFi. I mean, you must disable the encryption settings of the router. But this is only for testing purposes.
    The WiFi network must always be secure.

  • is it possible to send airtime on a mac mini and connect to multiple screens (5)?

    Hello - I'm looking to see if it is possible to use Airplay to a Mac Mini and connect to five different views and see the same thought at the same time. I understand that each display would need its own apple tv, but I don't know if it's strictly a ratio of one to one, or it would be better to run the HDMI from the mini and feed a splitter HDMI and wire them hard. I want to run a video loop of an IPAD for the mini and the mini to distribute video on screens. Thank you.

    No, this is not possible with Apple TV.

  • I keep getting "the trust relationship between this workstation and the primary domain failed" error windows 2008R2

    Hi all

    I appreciate your help. And I hope that this issue has been addressed previously, although I couldn't find any solution there.

    I manage a domain windows 2008 with 3 domain controllers. Recently my workstations continue to fall out of the field. I get "the trust relationship between this workstation and the primary domain failed" to many workstations.

    I know how to fix properly, use netdom.exe. But the mistakes keep coming back. I don't know where to look for the source of this error. A possible problem might be the time in any field is out of sync. But all my workstations synchronize with the domain controller with the primary domain controller role and seems to work correctly.

    Are there other sources, that I need to check? This is getting frustrating.

    Thank you much for the help.
