Differences between the ISCSI connections to the storage in vSphere 4.1 and 5.0.

I'm in trouble of setting up the connections of storage in a new VSphere 5.0 test environment. In our environment VSphere 4.1, it was possible to create a virtual switch add two Broadcom NetXtreme II 5709 NIC. Set assets. IP Hash value as load balancing. (LACP Etherchannel on physical switches) This configuration uses a grain port and a single IP address. Then add our NetApp NFS storage and ISCSI Equillogic storage. In VSphere 5.0, I can't create this same configuration. I have to create separate with separate IP addresses vmkernal ports? The idea was to have redundant connections to the storage and flow of these two NETWORK cards. Possibly adding additional if necessary to the futuer NETWORK cards. Any help with this would be greatly appreciated.

How can I work around this:

"VMkernel network adapter must have an active link exactly and no waiting rising to be eligible for the iSCSI HBA connection."

I can certainly say that the way which allows you to configure the iSCSI Multipathing is incorrect.

The main idea is to let Native Multipathing Plugin to decide what network path to choose, not the vSwitch.

At the level of the network layer, you must have 1 VMK by a physical NIC.

This technique applies as well for vSphere 4.1 and 5.0, but with the 5.0 it is configured easier and more quickly.

Here's a very brief consequence of steps

1. get 2 VMK interfaces and assign an IP by each VMK.

2. set each VMK to use only one physical NETWORK adapter

3 GB with storage iSCSI software adapter, turn it on and bind your VMKs 2.

4 connect to your iSCSI storage space

5 rescan devices, create the VMFS datastore

6. set the desired load balancing VMFS method or just set up a prior default create new VMFS

  • Differences between the version of BlackBerry Device Software and platform. Help, please...

    Hi guys!

    I'm really confused... Help, please!

    We have developed applications for our customers. We tested with our BB8700 and it works fine.

    We used JDE4.2 for development... and we think that it will work on v4.2 based handsets.

    But our customers wrote that it works on v3.7. Why? Is this possible?

    I looked at the information about my 8700 device and then noticed: v4.2.1.107 (platform v2.3.0.84)

    -What are the differences between the version of BlackBerry Device Software and platform?

    Possible customers spoke of version 3.7 of the platform?

    There is a list of the devices, where we can find the version of BlackBerry Device Software by BlackBerry device model?

    Or where we can find information about the models of devices that will support our application?

    Thanks in advance!

    AFAIK there is no version 3.7 platform.

    Customer talking about the OS version.

    So, if they have the device OS version 3.7 you must use JDE JDE 3.6, 3.7 or older.

    Or take updated device OS if the necessary software is available.

  • What is the difference between the two publish to ftp host and export as html in Muse?

    What is the difference between FTP publishing and export as HTML in Muse? When I had some problems with missing assets, I exported as HTML and fixed it, but it didn't update on the layout of the phone or completely on the desk until I published on ftp. Assuming that perhaps export just updates the files on the server? Thank you

    Hi Brian,.

    Site as HTML export will export just your Muse site on your desktop without making any changes to your site online, but when you select Publish to FTP, it publishes the changes you did for your website online.

    Export to HTML format is mainly used when you want to use any external client to load your site on the server.

  • Are there differences between the new 40 "W600B HD TV and a Costco sells Model # W590B?

    You want to buy this TV at Costco for $20 less. I was wondering if anyone knows if there are differences, large and small, in the 600 vs the 590? They seem to be the same in the literature.

    If they are the same, I always wondered why Costco and other big-box retailers have their own model numbers?

    They should be the same or almost identicle big box retailers often have exclusive model numbers to protect them from price matching, or sometimes to add or remove certain elements of their price and specifications.

  • Difference between the backup of database to copy and backup of database

    Hi all

    Kindly differentiate between backup database copy and backup of database.

    Thanks in advance.

    Hello

    With image backups, you have the option of two things:

    1. use these as rman backup and ask to restore them to the desired location (the same that we do in restoration of backupsets).

    2. tell the database to use these files.  This is possible by ' switch database copy. This is useful when the recovery will take a long time.  This allows you to move the users directly to the backup that you restore to the original location.  In other words, your database remains open with the users who access the copy.

    in both cases, you would:

    1 restore a controlfile

    2. the backup catalog

    RMAN > catalogue start with noprompt "/ backup location, in this case copy data files."

    3A. If you want to restore the database, so you might as same as usual:

    run

    {

    Set up until...

    newname Set...

    restore the database...

    recover the database...

    }

    ALTER database open resetlogs;

    3B. If you want to "switch" to the backup, you must run:

    switch database to copy;

    recover the database up to the...

    ALTER database open resetlogs;

    NOTE: before open resetlogs, remember that your online log file location is valid for the server on which you are restoring.  See:

    Hello

    I'm about to create a backup image of my OS, but I can see an option for a system repair disc, but in a previous question, I was told that the original install media will suffice.

    Should I create this image or only be concerned about the system.

    Thank you all.

    Just three days ago, I used a Windows 7 (without SP1) installation disc to restore a System Image of Windows 7 with SP1.

    If you want, you can create the system repair disc, but it is not necessary.

    Hello

    What is the difference between the full version of cs5.5 and the oem version of windows?

    can I upgrade the oem version?

    Thank you

    Software OEM is not transferable, but it may be useful to check any documentation you have the purchase of your computer, as a lot of software that good people was OEM, was either a trial version we bought later, (after the expiry of the test), or a full version pre-installed with a serial number that we paid when buying the computer.

    If it's the latter, then it should be transferable to a new computer, if you have the original serial number.

  • Y at - there a big difference between the base of the m3 and m5 models?

    I had my m3 2016 Macbook for a week so just thought I would ask so that I have time to exchange it if need be. I wondered outside storage space, y at - it a big difference in processors Core of m3 and m5? Apple uses a "customized" version of the processors? I ask because Apple lists the m3 1.1 Ghz but not apple models are call at 900 mhz.

    The processor is clocked at 1.1 Ghz. There are different models made by Intel, including that which is supposed to be clocked at 900 Mhz. Apple does not use a customized version of the CPU. The differences between the M3 and M5 model is displayed on the Intel Web site. Among the differences are the M5 is clocked at a higher speed and the M5 is generally about 15-20% faster than the M3 at the same clock speed.

  • What is the difference between the VI of the histogram and the General histogram VI?

    Hello

    I did a google search and forum for this and came up empty. I would like to know if there should be a difference in how the work of both?

    I ask because I gave exactly the same table both X and was two different results, unless I also specified the interval bins / # to be equal for each of them. (level for the VI histogram and #bins for the general histogram VI)

    It also means I want to know the difference between the intervals and #bins? They are the same thing with different names just?

    It's more of a general idea on how the two screws work to obtain a specific solution to a problem, anyway, so any help is appreciated

    Thanks in advance.

    Pladio wrote:

    Thank you. No idea why the same data would give different histograms when the specification is not garbage?

    Yes.

    The normal VI, if you do not connect the entry "interval", will give you 10 bins, becaue that entry is set by default to 10.

    The advanced VI, if you do not connect the "#bins" of entry, will give you a number of bins from comment how are made, or the size of the incomming table. This number is 1 + 3.3 log n, where n is the size of the array. This is called rule of Sturges, and is more or less explained in the programming of this VI. Open it and look at it.

  • Difference between the series & ethernet interface.

    Hello world

    I have some doubts in basic foods.

    Q1: What are the differences between the interface series and interfaces ethernet.

    Q2: Can we use ethernet interfaces to put an end to a WAN connectivity like series. Why always we use interfaces series to connect the Wan.

    Please help me by answering these questions.

    !!!! THANKS IN ADVANCE!

    Hello

    Fast Ethernet card is one of the option for a higher speed T1/E1, other TDM options that can be offered are DS-3 and STM1 that can be offered on infra nominal basis as well. For example, you can subscribe for 10 MB BW on 45 MB access.

    The answer to your second question, is that there could be a possibility that you have subscribed for VPN (EVPL or VPLS) L2 or L3 VPN (MPLS).

    Woks of L2 VPN on labels VLAN and L3 VPN termiantes on a device of L3.
