Port of heart beat Vmkernal of storage for table Equalogic PS

Dell has just installed a new EQL PS SAN and configured for our 5 x ESXi hosts 5.0U1. Each host has 2 10 GB NIC have inaugurated a vswitch dedicated for iSCSi connections to the SAN. MPIO is via the driver of Dell MPIO add-on.

They are configured so as to VMK 2 ports iSCSi1 ands iSCSi2 1:1 as usual. However, as Dell has left, I came across a Dell/EQL (TR1075-Configure-iSCSI-Connectivity-with-VMware-vSphere-5.pdf) white paper that says that a separate vmk port must be configured to maintain "pingability' of the iscsi ports during failure/failover. This port must have an ip address on the iSCSi subnet and 2 10GB network adapters must be active in the team but are not related to the iSCSi adapter. It should also be the port down vmk not.

The following positions in various net forums seem to suggest this is very important: -.

If it is there, it is easy to create the additional vmk but how I would make the lowest port without deleting existing ports and access of SAN interupting.

Kind regards

5.1 ESXi does not resolve the problem, then the kernel of Heartbeat of storage (SHB), is no longer necessary.

However, with ESXi v5.0 you don't have to remove the two ports VMK and start from scratch.  You can unbind the VMK port below via the GUI ESX.  Then, change the network cards so that both are active.   Then create a NEW VMK port in this subnet that has bound to the iSCSI HBA to replace the port lowest VMK used for SHB.

  • Request for lack of events/heart beat

    Hi all

    I'm trying to monitor network packets I send to a specific ip address and also check if I sent packages for that IP special at regular intervals (something like a heartbeat). I transfer the wireshark network output to a csv file and reading in PART with csv adapter.

    In order to check for missing events/heart beat (this is used to check if a server responds to the ping at all hours), I followed this link
    Re: CEP non-event programmer and
    [http://docs.oracle.com/cd/E21764_01/doc.1111/e14476/examples.htm]
    I configured the PART. This is the query that I'm shooting

    of FilterNetworkPackets

    DURATION 10 DEFINE Ipdst_Packets AS ipdst = "xx.xx.xx.xx")
    As packages

    I have configured heartbeat (10000) on both inlet channel.

    I get output in which some packages are repeated. I don't know how to obtain a missing event notification once the elapsed time, please help me.
    Thanks in advance

    Hello

    The output you get is infact the notification you receive when there is no event with 173.194.5.140 for 10 seconds.

    for example, the first exit.
    OutputBean:onEvent() eventType = RequiredMailFields object plus RequiredMailFields ki
    ND = null time = 696477423597 ipsrc is 192.168.0.10, ipdst = 173.194.5.140.
    elt_time = 686477423597, framelen = 5, alertType = error-Missing event isTotalOrderGuarantee = false

    Elt_time here's the moment where the event happened and time is the time associated with the output. If you subtract elt_time of time, you will notice that, for each of the output, the difference is 10 * 10 ^ 9 nanos = 10 seconds. So the output above should be interpreted as "no case with ipdst = 173.194.5.140 arrived 10 seconds after the event with framelen = 5' and therefore the notification is generated.

    You don't see any output event that has framelen = 3, because after the framelen = 3 entrance arrived, the following entry (with framelen = 5) for this partition arrived before the 10 seconds duration expired.

    According to your requirement, it seems that you need some sort of indication in both cases:
    (1) whenever an event happens with this ip address - will mark the beginning of the green line
    (2) when any does happen for 10 seconds to this ip address after receiving an event for this ip address - will mark the beginning of the red line

    I think you can model this as follows:

    review from normalEvents:

    Select ipdst as ipdst, ipsrc as ipsrc, framelen as framelen, 'The Normal event' as alertType, ELEMENT_TIME as elt_time from FilterNetworkPackets

    Discover the missedEvents: (the existing query - added ALL clause MATCHES MULTIPLE so that you get one out every 10 seconds until the next event happens for this partition)

    SELECT Packets.ipdst AS ipdst, Packets.ipsrc AS ipsrc, Packets.framelen AS framelen, 'Error-Missing event' AS alertType, Packets.elt_time AS elt_time
    of FilterNetworkPackets
    MATCH_RECOGNIZE
    (
    PARTITION BY ipdst
    MEASURES
    Ipdst_Packets.ipdst AS ipdst,
    Ipdst_Packets.ipsrc AS ipsrc,
    Ipdst_Packets.framelen AS framelen,
    Ipdst_Packets.ELEMENT_TIME AS elt_time
    ALL MATCHES
    include timer events
    MODEL (Ipdst_Packets) DURATION MULTIPLES OF 10
    DEFINE Ipdst_Packets AS ipdst = "173.194.5.140") AS packages

    AllEvents query:
    Select * from (normalEvents union missedEvents)

    On the release of the 'allEvents' query, based on the "alertType" of the event, you can trigger appropriate treatment in the bean output.

  • We can connect Heart beat IP with cross cable

    We have 2 DB serverv, on each server, we have 4 NIC, 2 for 2 data (IP heartbeat) cluster.

    I want to connect two heart beat IP address of the server through cross cable.


    Please suggest the advantages and disadvantages as very important in my case.

    Oracle not recommend to use * "Cross cable" * inter connect... You must use the switch Gigabit (no Gateway) for best performance.

    If switch part with public... to make the VLAN ;)

    About "cross cable"... when hung node2, which can make interconnection on node1 network have the problem.

    I hope you'll use the switch for it (audiophile)

  • Flash does not work in FF26, it works in Chrome and IE. I reinstalled FF and Flash several times. I can't adjust the setting of local storage for Flash either.

    Flash does not work on some web sites. I never had a problem before with flash on FF in the nearly 15 years that I've used FF. Recently it has stopped working for some reason any and on some flash sites does not, NHL.com and site of kid Herotopia being just two of them. I updated FF, Adobe flash, the reinstalled version them repeatedly deleted all the files that have been stored on my laptop; that is, profiles, saved favorite nothing that I could find in user accounts and in the local app, low local and roaming data folders. What is strange, is that I can't set the local storage for flash either. When I visit the Adobe site to view the Adobe Flash Player Settings Manager I can move the scroll bar, but cannot check the: allow third-party flash content to store data on your computer. I can't do it on a Web site where the flash does not work. When I try and it changed on any site that it goes back to zero. Not sure if it is a part of the problem. I got tired of many suggestions on the pages of material here, but nothing works. I even tried this http://forums.adobe.com/message/4566499#4566499#4566499

    The other strange thing is that I used to get the "warning: script does not" prompt that displays "a script on this page may be busy, or it may have stopped responding." You can stop the script now, or you can continue to see if the script ends. "sometimes when I would buy on Macy's.com. This is the only site that it happened.
    I know I have only little technical knowledge, but I have tried to figure this out for a few days and do not know what is happening. The only thing I can think is that I somewhere files corrupted causing this problem. I have just updated to Windows 8.1 tonight in the hope that can help, but nothing helped. I would be very disappointing if I couldn't use FF or must go back using Chrome and FF.
    Sorry for the posting long but no solution would be much appreciated.

    Hi jscher2000,.

    Yes, I followed essentially the: Manual steps: https://support.mozilla.org/en-US/questions/968190?page=5#answer-509209 you have posted.

    And after restarting Firefox, Flash worked. Thanks again for your post I could not find this solution on the Adobe forums until you have posted the link.
    Your expertise and your time is much appreciated.

    What is the limit of storage for "indexDB" in Firefox 4?

    I need to know because I write a significant demand with local storage requirements.

    More the 5 MB limit in the Local Storage API.

    Your response is appreciated.

    Thank you
    David

    If the user grants permission for a site to exceed the quota of 50 MB IndexedDB, then as much as I know Firefox is no limit more. The only limits on the size of the IndexedDB database will be the disk space of the user and operating system.

    The quota of localStorage is 5000KB and there is no way for a web site asking the browser for permission to store more than that amount in localStorage.

    1. product name and number: Pavilion DM1 4027sa / qj516ea #abu

    error 3 message: N/A

    4 all changes made to your system until the problem occurred: cleaning of Windows 7 DVD (commercial version)

    I recently did a clean install of Windows 7 64 bit on my laptop from DVD true retail because the resumption of HP I is 32-bit and so cannot use all the memory in the machine.

    I managed to find the most important software and drivers but miss me the beat / Audio driver. It does not appear on the page of download driver laptop (with another software, but that's probably another story).

    I found and installed HP Support Assistant, and who concluded that the Beats Audio was missing and that would have been installed (unless she didn't and he didn't tell me). However, he seems to still be there - there is no Beats Audio icon in the system tray and it is not something that you can uninstall in Control Panel. I also installed HP on-screen Display as it seems to be necessary, but it does not seem to have brought Beats Audio to life.

    Lack of pilots of Beats Audio seems to be a common theme on this forum, but unfortunately none of the opinions of existing positions worked for me. I suspect it is maybe because none of them focused specifically on my laptop model.

    Can someone point me to the Beats Audio / IDT download for my PC model or suggestions for other ways to get installed it. Note that I have no HP Recovery Manager installed because I can't find that download is...
