HP MSA2324i, new volume / LUN added, cannot be seen by the host ESX 4.1 (fine old LUN work)

Hello

I have a vSphere Essentials Plus 4.1 cluster that is connected to 2 x bays HP MSA2324i SAN, we have 2 x hosts and both can see current volumes / LUNS absolutely perfect (vMotion and migration of VM offline all work as expected). I'm starting a consolidation project virtual disks / volume of the San 2 x, however a new volume I created on a network SAN cannot be seen by the other host.

The new volume has been implemented exactly like the others, but of course with a unique logic for mapping unit number explicit, but when scanning the iSCSI HBA the new LUN is never found :-(

I was wondering if others have had also this happens to them and know why this may be implemented?.

(This is a company that I joined, it's my third week, and that they had also no VMware subscription on their reunification since 2012, otherwise I would be to connect a call to technical support of VMware, by train to get the sub upwards and running)

OK I think that might be the cause, I came across this recently maximum LUN ID is 255, change the logic unit to a number smaller than 255 ID number and try again, let us know how you go!

  • How to get the host ESX DR see replicated Celerra Lun

    Hi guys, Im setting up SRM with 2 x NS20 and ive got regarding the configuration of the LUN on the production storage array, Lun on the storage LUN appropriate to prod/dr esx servers present DR Bay. Ive set up replication and added the DR lun to the esx server, ensuring not to add it as he will write a signature. I've then added the production on the production ESX Server LUNs, added storage which obviously writes a signature on the drive, and with the installation of the replication, I expected to simply issue a new analysis on the DR esx host and do see the data store.

    Am I missing something here? Any help would be appreciated.

    Thank you

    Hello

    "On DR NS ive done exactly the same thing with respect to FS, Lun, target iSCSI and presented to the host ESX DR, ive done a rescan and his picked up the lun 'Read Only', which is being replicated in but the tab of summary in VC, I see that the local VMFS file system and I was expecting to see the replicated LUN listed with the store local data or is this seen only". When SRM changes the properties of Lun during a failover? »

    You will not see the Site recovery volumes listed in data warehouses, unless you do one of two things - a failover in which case the production side will be unalterable and be removed from the list of data on the Production side store while exposing the VMFS data store now read-write on the side of the recovery.

    Or you use the test function in which case that encourage a wink of Celerra temporary writable and it will appear as a data store broken in the list on the side of the recovery VMFS data warehouses.

    However, it seems that you do not see this result, as DR table does not seem to be configured as it should.

    Can the side Production VC communicate with happiness with the Celerra recovery site - IE can launch you a session PUTTY from the Production side VC and connect to recovery side Celerra. Can the recovery side VC do the same thing for the Production side Celerra?

    I guess you get the unknown peer after that MRS. not the discovery of the table that owns about 23% forever and then ends. The only other thing I can think of and am not sure about this as a solution because it is a set of actions that I did of my side of recovery when Celerra is to create a small file system and in a small iSCSI LUN on the side of the recovery of the recovery side Celerra and put it in your recovery ESX cluster side - create a file system VMFS on it and place a Virtual computer in this VMFS file system - this is to check that there are no problems with the ESX host side recovery working with the recovery side Celerra

    My guess would be a thing of IP connectivity - if it's a little strange, if the link between the Production side VC and the recovery side VC has been established successfully

    I'll pass on to a colleague to VMware SRM and see if he has any ideas

  • WAMP and installed WA - gap DW now cannot make connections to the host

    I am learning PHP and recently installed WAMP to use a cart Web application help.

    Now Dreamweaver cannot establish a connection to the host. It gives six reasons why it can not connect:
    -The network cable is disconnected or the network is down. (It is connected and more)
    -The FTP server is down (it's towards the top)
    -The FTP host name is incorrect. (it's good)
    -The server using SFTP and the checkbox 'Use secure FTP' is not enabled. (he does not SFTP)
    -The server using FTP and the checkbox 'Use secure FTP' is checked. (The box is not checked)
    -Access to the server requires firewall that are not correctly defined settings. (requires no firewall settings)

    I had no problem before WAMP and gap.

    I get something dirty when I installed WAMP (Apache, MySQL and PHP)?
    Or is the difference in throwing things off?

    Nobody knows what could happen? I am at my wit's end and could really use him some tips.

    No problem. I think we all made purchases that seemed to be the right thing to do in time. It is without a doubt the nature of this game. You should see my shelf of books of 50 dollars I'll never watch it again. in any case, he is screwing with your regular ftp connection? on other sites? in this case it may be a firewall problem. try turning off your firewall for a second and connect. If that's the problem, you must have a problem with your installation. I use this server wamp without any problem:

  • OfficeJet 4650: New HP Officejet 4650 cannot be detected in the wireless

    Have tried to install this printer with the 8.1 Windows wireless configuration wizard and Windows 10, and none of them can detect this printer on the same network. Manually enter that IP address of the wizard is not working too.

    I also changed the printer IP of the DHCP server to static, same thing.

    The only way it can detect the printer is through windows 'Add a device' where it appears a list of the devices in which 2 printers named with "Direct-*-4650". "» Not sure one to choose. Choose anyone of them will allow you to connect to this printer once. Next time, this printer can print either.

    An observation is for Officejet 4650, he cannot be crazy; Unlike my other Deskjet 3050 a, its IP address is to ping requests.

    Run the printer doctor tool too, and just, it freezes and sucks CPU forever without getting anything in return. What tool joke.

    Please help me if possible.

    Thank you

    Just return to the issue with the solution. After working with HP support, we discovered the root cause. At home, I used extensions of TP-Link powerline to basic wireless network and ending up with 4 more wireless relay networks that are all on the same subnet and masks. Home, the devices are connected to different networks wireless in places and they have no problem to connect to each other.

    However, this printer 4650, if the Setup program on one basis other than directly connected to the router network, it will be inaccessible. It can be reached from the core network; and all devices on other networks can reach it after that. Another printer, HP 3040 A, has no question also and can be installed on any network.

    Seems a limitation of 4650 printer!

  • LAPN300 Workgroup Bridge cannot be seen outside the local subnet

    Hi, I have a strange problem, I hope you can help with.

    I have the following in my network

    3. another AP connected to [2] via the parameter Workgroup Bridge [2]

    All appear to be configured correctly, [2] shows that [3] is connected in the section of bridge of the workgroup of tha status page.

    When I connect a wireless [2] client I can ping [1] and [3] and an external address as Ecritel.net

    When I connect a customer [3] wireless I can ping [1] and [2] BUT cannot ping an external address

    All 3 cameras have manually set IP addresses x.x.x.254, x.x.x.253 and x.x.x.252

    only [1] has NAT and DHCP active.

    I already tried a different router [1] and a different access point [2] but get exactly the same result.

    Do you have an idea what I'm doing wrong or troubleshooting.

    Thank you chadster766

    Yes you are right. I had the network defined as

    Modem => LAPN300-online WAG120N

    I have now tested it as you suggested

    Modem => WAG120N-online LAPN300

    This has indeed fixed the problem.

    UnfortunatelyI cannot use this topology for my solution that I need the LAPN300 my AP central.

    Can you advise if there is another device that I can use instead of the WAG120N?

    If I buy another AP support WDS which will work with the LAPN300?

    Is there some other wifi feature that I should be looking, or should I just get a wifi Extender?

    I need the final configuration to be like

    Modem-ethernet online => LAPN300-wifi-AP online online? -Online wifi-online PC Client

    Thank you for your expertise.

    I would recommend either a LAPN300\600 or if your budget can support a LAPAC2600 which is newer Linksys AP.

    You can continue to use Workgroup Bridge or WDS. They both should work. I don't know which protocols are better.

  • Cannot stay connected to the network, even after replacing my old router.

    I have a laptop Toshiba Satellite L655 is one year old and its operating system is Windows 7 home Premium I have Comcast internet service and use a NetGear wireless router.

    Recently, about 2 months ago I got this router in Comcast, in replacement of my old 1. Why I asked that a new router was the former 1 had problems to stay connected to the internet. The problem persisted even with the new router so I look at it is not not a problem with Comcast or the router. I tried resetting the connection, the son, restart the router, diagnostics running on my laptop and are not yet able to resolve the problem. I run disc optimization, defragment the hard drive, run many virus / spyware scans and tried to disable startup programs as much as possible. This problem has frustrated me for months and I want to get it resolved. It sucks paying all that money for equipment and service and there not work directly without having to spend more money, which I have unfortunately not yet. Any help is very appreciated.

  • Cannot insert .aom file in the DW CC page despite trying various forum boards. Hoping that it is a problem of liaison and base folder organization. "Year" shows the page, but it cannot be seen in the browser.

    Hi people,

    I have a problem which can be laughable to some as I'm a newbie. I tried for weeks insert my edge .aom file animate CC published in my Dreamweaver CC pages with no luck so far. I hope it's just a problem of basic organization, the reissue of links/folder.

    That's what I've tried so far. I followed the standard basic instructions on various forums without success. I found that the folder structure that my Edge animate published was different from the default folder structure in a tutorial that I read. My containers are fluid but I kept getting 'the height is zero', "Width is null", until I manually inserted the dimensions in the code. Now, I get a "A" display on the page but still not animated in the browser. My homepage with its old animation intro works very well despite me trying to fix by moving files around a website that now looks like the dog's breakfast. I tried constantly to correct the links broken with mixed success. The list of broken links report shows some as 'unassigned assets' which I do not know how to fix.

  • Adding a virtual processor for a host ESX 4 UP1

    Hi - I built a SLES10SP3/OES2SP2 guest and now know that she could really benefit from a second processor.  Simply change the '1' to '2' is not recommended - not to mention that it does not add a processor according to the operating system.  I've seen several articles dealing with the change in the number of virtual processors, but none seems to be right on the target.  Seems more talk about reducing the number of processors, talking about the Windows VM, etc..

    Can someone tell me the correct procedure to follow - if it is still possible to do!  The physical server is a physical processor 1 HP ML350 G6 which indicates 4 x 2,266 GHz processors cores in the vSphere client.  8 logical processors. Xeon E5520.  I use vShere 4 Enterprise Plus.  The use of CPU resources as is currently around 10% used on the horizontal bar to 1143 MHz chart.  From time to time, it stings at 2400 MHz. The capacity is 4 x 2.266 GHz.

    There are 11 active VMs (SLES, 2003 and Netware) running in a pool with the default settings of the Pool.  There's a VMs additional 4 in the same pool currently shutdown.

    If it works, I want to do on 2003 server as well.

    FYI - I also built a SLES10SP2 server from scratch with 2 virtual processors and operating system takes advantage of them.

    Thank you vey,

    In general, you should try to work with as less as possible processors. However, you can add more, if you need.

    The VMware point of view that is easy, just change vCPU th enumber.

    Depending on the guest operating system and the kernel/HAL used, you need to change this one a multiprocessor.

    On the computer host vista, I'm completely unable to see the XP VM.   But the XP machine, I see the host in my network places, but when I click it I get the followign message.


    & lt; host & gt; is not accessible.  You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access.

    The network path was not found.

    Not sure if the problem is a problem with the settings of Windows network or something related to VMware.

  • New VM vCenter and need to connect to a host ESX1 4.1.

    Hi all

    I'm in a difficult situation not in my enterprize environment, but someho I am very confused after a few hours by train.

    Currently I have an ESXi host 4.1 with some virtual machines on it. One of these virtual machines is the vCenter server that had been upgraded to version 5.1 a few months ago. The vCenter Server runs on a virtual Windows Server 2003 64-bit machine.

    Two days ago, I decided to upgrade the vCenter 5.1 to 5.5, but unfortunately the version 5.5 does not work on a Win 2003 server. So I installed a new virtual machine with Windows server 2008 R2 and the plan is either to migrate the new everything from the former vCenter, or simply connect to the new server vCenter with the host (I have not run any complicated environment, I have only 5-6 virtual machines and the only thing that I would need the former vcenter is a few shots but I don't like if I don't get them).

    First, I installed the new vCenter (5.5) and I connected to the host. I logged in as [email protected] , and I could see the server vCenter there. I've added my account domain in the Administrators group and the VCOAdministrators group, but when I connect with my domain account that I do not see any server of vCeter it.

    Now, what I want to ask you is: you have read above I want to do. What would you do if you were me?

    Thank you for all your answers.

    Sign in using the account [email protected] and check the permissions on the server vCenter Server object in the inventory. Make sure that the required domain user (or better yet a domain group) has the appropriate permissions to the object and the objects below it.

    Adding an account to the Administrators group internal grant permissions required to manage the server vCenter Server itself, but does not apply to the inventory.

  • Questions VC... Add the host to the new CR?

    If I have problems with my VC server. It does not start for some reason, so I'm building a new. The question I have, is if my 6 ESXi hosts were connected to this VC how would I so that they know the new Victoria Cross? I know that the right way to add hosts to a new Victoria Cross would be to disconnect and then remove them from the existing VC. Any thoughts?

    Thank you.

    If you cannot disconnect and remove the hosts of the other environment, simply ' add host' in the new.  You will receive a message saying something to the effect of «Eastern host is managed by a different vCenter...» Once you add the new host vCenter inventory, you'll be fine.
