How to maintain the availability of the data store after the upgrade to ESXi 5.1 with the new IP address and the naming convention?

How can we maintain access to the presented LUNS and VMFS data store after we improve the ESX in ESXi with the new naming convention and the new model of IP addressing?

My back-end SAN EMC Clariion is VNX

Thanks in advance.

How are the hosts connected to storage systems. With FC HBA for example, there is basically nothing you need to do since the WWN will remain the same and so LUN presentation of the zoning on the switch and storage system does not need to be reconfigured.

    We use Verizon as our ISP.  I was getting our email to two different companies by connecting to Verizon in with another user name and password for each company.  However, we have received messages in our email that we were almost our quota and customer emails we would not come through and have been having rebounded.  I spoke with Verizon and learned to use a 3rd party to channel messages and thus free up space from the server.  They helped me to set up the email to go in Windows Mail, but now all the email for both companies will in the same e-mail account.  How can we separate the email for both companies so that each company can log on to Windows Mail with their own separate IDs and passwords?

  • How to maintain the life of your printer

    It seems more common that everyone feared how to maintain the service life of the cartridges from the printer itself.  As many variations of parameters and environment may play a role in how long your ink will actually last. A more official document can be found here about the science behind the ink, how to use it and how to make it last longer.  I will get into issues that affect the overall performance and life cycle of the printer.  I recommend to use the Startup ink supplied with the printer until he is gone because it contains chemicals of this condition and prolong the life of the print head for future use.

    I urge users to keep the printer connected directly to a wall outlet (namely for troubleshooting purposes). As with all electronics that are showing signs of failure, you can start with the power source if one really wants to follow the flow of a schema logic.  By eliminating the devices that can not to themselves, you removed a piece more equipment from the equation.  A more specific reason would be due to electromagnetic interference.  Wireless devices are vulnerable to interference with symptoms like error messages of false, lines in digital images, strange noises and frequent jams.

    Surge protectors must regulate the power distributed to each connected device.  It is possible that the printer is not the right amount of power and may fail as the printer power problems in hibernation mode with more features like duplex printing, it is impossible to recover , cable USB not detected and the light on the module displaying a yellow instead of green.  If the module and the surge protector are fighting for the control, it can cause a variety of problems that could easily be repaired by plugging the printer directly into a wall outlet.

    The next major issue many users face is the print head.  It is as well as the maintenance of ink as well.  It is important to clean the print head and the best way to do that is to use it and keep the good ink in the printer.  Over time, the chemicals can not even begin to change or develop air bubbles in the cartridge.  Not to mention, ink (well pigmented) still contains fluids that can evaporate if the printer is not rooted and off properly when not in service.  Of course, some of the processes of preparation printer used when the power of the printer can use very valuable ink, but, on the other hand, it's good for the life of the printhead to leave these processes to perform according to its specifications.

    The print head is composed of tiny nozzles and parts fragile this is why it is also one of the most expensive areas of the printer.  Most printers contain many self-cleaning utilities which is recommended to regularly (I suggest at least once a month) to help keep the printhead clogging and causing stains on the sheet itself. There are a number of unconventional methods to try once the printhead has dried up in fact, but when you try these steps you may totally break the part.

    Dust and smoke particles can also cause problems with the print head, but the printer entirely.  It is often the main killer of electronics as well as hairs and animal dander, dirt from moisture and humidity, paper for printer cheap and sand.  The air is full of impurities and really can not be prevented.  Preventive measures can be taken with dehumidifiers and a uniform cleaning, but over time, there is no real way to prevent it from happening.  Dust and air blowers have been known to cause not only solders to separate but may deposit particles of dust in places that could actually damage the printer entirely.  Instead, a favorite device is known as an empty computer.  It helps to remove the fine dust in the sense just that pushing forward into the printer.

    Paper jams also cause many more problems if is not removed correctly. HP recommends pulling the paper in the direction of the gears.  When removing a paper jam, you won't hear a grinding because it leads finally to the teeth are stripped like a screw, but simply once fully detach one of these devices. It is virtually impossible to fix a paper roll or similar because all parts are connected to each other and not sold in parts stores.

    At the back of most HP printers, you can remove the rear access door or duplexer (double-sided printing device) and easily join the paper in this way.  If you see the paper jam is located next to the Board, and then remove the piece from the back and take the paper with both hands to apply a gentle tug of same, and you should have no problem in removing the paper in this way.

    Paper quality can play a large role in the life of your printer.  Cheap paper can free of paper dust up into the gears and small machinery within the printer and are very difficult to clean.  Print incorrect parameters and issues related to food can cause the paper to stay in places that are not as easy to do.  In this case, remove the paper as long as slowly and patiently as possible to avoid them ripping out pages in places like between the wheels under the printhead and also causing error messages that will not disappear.  When troubleshooting printers, patience and troubleshooting documents will also help you keep your printer running longer.

    The printer doesn't like to not be put off by anything other than the power button.  I have always recommended the printer off when not in use (at least for long periods of time) to help keep the ink dry and high printing quality.  The reason why it is not recommended is because people will be unplugging the printer, while he is doing something and the negative effects that this might have some alignment problems serious, burn the computer chips and components similar to that in computers, fake error messages and possibly bricking of the printer if done at the wrong time.  Resets hard are great troubleshooting steps, but the abuse of this feature can result in irreparable damage.

    Fanning the paper before put you in the status bar is a good practice. About 25 sheets are perfect, because an overload of the status bar may also cause paper jams.  The paper guides of setting and selecting the appropriate paper type will put the science behind these settings wisely. Don't put paper in the tray while the printer is printing, crumpled, dirty, or coexist paper types and paper clips are all things to avoid.

    Software and communication issues deserve a section all to themselves.  The measures to prevent problems of this kind could not covered in a post, let alone a chapter.  The best thing to do to increase the performance and connectivity is to set a static IP address in the URL embedded in the printer if the printer is set up on a network (steps to do this are different from the printer to the printer).  USB cables must not be more than 3 meters long and kept in good condition as well as the power supply cord.  Keep your valuables out of reach of children and buy an extended service plan for many reasons.  You can enjoy all the services offered with a service plan in the case of a defective printer or simple product questions.  Keep the firmware up-to-date and to read reviews before you buy any electronic device.

    After reading this, I'm sure you're aware, that's all common sense, but at the time where you do not consider one of these suggestions you think back and wonder "if I had taken 10 seconds longer to avoid that I wouldn't spend 2 hours more set.»  Mistakes are made when frustrations and lack of care.  These are not delicate machines that deserving the highest shelf in the bathroom, but an understanding must be met, that once it's broken this avoidable?

  • Data store mobile (vm machine) 1 host to another with the help of free hypervisor on the two hosts

    I have 2 hosts running ESXi 4.1 (free version of the hypervisor). Both have their own data store locally.

    I need to move a VM machine (data store) of a host for the other local data store. There best way to do this with the free hypervisor?

    Hello

    Using VMWare Converter standalone 4.0, it's a free VMWare tool exactly for situations like yours. I use the conversion tool to transfer my virtual machines much between different hosts of ESXi and also founded to convert ESXi VMs to VMWare Server/Workstation and vice versa.

    All you need to do is turn off the virtual machine and make sure that it is in the inventory of the ESXi host source; Use the VMWare Infrastucture option while selecting the source and the destination of VMWare Converter Standalone, you will be asked to provide identification name and connection of your ESXi source servers and destination information.

    VMWare Converter Standalone is a brialliant tool, its very flexible in that you can resize your hard drive, use a provisioning, edit all devices.

  • How to put a CustomField on a data store?

    Hi all

    I tried:

    Get-myDS data store | game-customfield-myName-name-value myValue

    but no luck.

    I also note:

    $myDS = get-myDS data store

    $myDS.extensiondata

    There is a field called:

    "CustomValue.

    How to fill this extensiondata. CustomValue field?

    Even if I can't put a customfield via whole-customfield, is there a solution or a hack to store a value for a data store?

    concerning

    marc0

    I'm afraid that the New-CustomField and New-CustomAttribute in the current construction of PowerCLI don't support data warehouses.

    But you can use the CustomFieldManager to manage the fields custom data warehouses.

    First get the CustomFieldManager object.

    $cfMgr = get-view customfieldsmanager

    To create a new field, you can make

    $cfMgr.AddCustomFieldDef ("Test", "Datastore", $null, $null)

    This method returns the CustomField object. It is important to store this somewhere, because you will need the Key property in the following methods.

    You can also get this key by enumerating the fields available for any data store

    PS C:\ > $ds = Get - Datastore - name MyDS

    PS C:\ > $ds. ExtensionData.AvailableField

    Key: 591
    Name: Test
    Type: string
    ManagedObjectType: data store
    FieldDefPrivileges:
    FieldInstancePrivileges:
    DynamicType:

    To assign a value to the new field

    $cfMgr.SetField($ds.) Extensiondata.MoRef, 591, "A value") "

    To retrieve the value of the custom field

    $ds. ExtensionData.CustomValue | where {$_.} Key - eq 591}

    DynamicType DynamicProperty key value
    -----                                          --- -----------              ---------------
    A value                                        591

    Note that these custom fields of the data store are not visible in the vSphere client!

  • Group of port and the naming convention for vLAN

    What is the naming convention better for groups of ports on vSwitches?  This naming convention should match how we name them VLAN on the physical switches and how important is that?

    Hi VMinator,

    To answer your question, he has not agreed to 'standard' for names of portgroup.  That's all what you're comfortable with the support and what works for you and your organization.  A bit like server names; Some companies are going hardcore with the naming conventions and others their name after the characters in science fiction or world of warcraft bosses

    Forensic science more you pack in a naming of the control standard more you have (i.e. for scripts, health check, etc. see below).  Also, if the name itself answers questions on his own and allows you to save a phone call that is priceless.  For example - the guys says unix... "Uh which network to choose for my new virtual machine.  My IP is blah blah blah. "Well, with right portgroup name, this question would have answered itself... and maybe even recorded some interruptions of service in other cases by the simple fact of being clear and effective in the communication of how this virtual device should work: purely expressed through an appropriate naming convention.

    Here's another one.  My last concert, we had thousands of virtual machines that had to move data centers and when they landed, they needed to change the IPs and start using 3 vNIC (instead of 1) on each virtual machine.  Each vNIC with a different subnet mask.  All support should be conducted by a team of outsourced with minimum experience of VMware.  The only way to support something like this and be effective is PowerCLI.  With just invited the naming convention only, you can perform various tasks such as query the virtual computer and check its settings of portgroup compared to its actual IP information in the operating system, initiate a ping from .NET to the virtual machine, if there is any questions Act automatically.  Some actions that will have to be performed include, for example, change the portgroup or mask on a set of clients;  Or questioning guests and glean information network (CDP, vSwitch, portgroup of information etc.) and compare observed network vs network expected enumerated in the PG naming convention. etc etc.  The list of actions that you can take are limited only by your creativity.  The naming standards give you effective power both in manual and automatic efforts.

    Still, notice of one man, but every site I care and feeding generally ends with a PG standard similar to what I first described above in my previous post.  Don't forget my example naming convention is Basic.  There are many other attributes that you can add (i.e. in vCloud deployments, in addition to the info network, you can choose to identify various features specific to vCloud org-networks, etc.).

    TBH just most of the companies have appointed VM-network exchanges (ok not bad) or some random shortname which doesn't help troubleshooting.  They are fairly easy to fix and also change over time, if necessary.  You can easily drag and drop a set of virtual machines (although I don't personally do this way) in the new port group (via the page of networking to CTRL + SHIFT + N) or PowerCLI it (Yes!  way to go).  Of course, always the ping tests before and after the change.  There are a lot of scripts out there (or ask master lucd post in PowerCLI VMTN forums).  If this is net-news, then you are ahead of the game and will have a standard to follow, whatever it is.

    Best of luck and have fun!

  • If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

    If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

    The reason why I ask, is that I have two hosts ESXi ESXi 4 running.  I do my backups with ghettoVCB, which I modified to create thin backups on one of the drives the.  I then wput them to the server, which causes them to become thick.  Directly targets the backup in a vmfs iSCSI on the server in the face shop.  It would save a step and the vmdk backup should remain thin.

    Thank you!

    The short answer is Yes. If you allow the ESX servers to see the LUN. This setting is configured to the Openfiler.

  • How to maintain the synchronization of the hierarchy of the table with customer-specific data

    Series of paintings in our system, we have:

    Promotions (id, descr, datefrom, dateto,...)
    PromotionClients (promotionId, clientId) = list of clients whose promotion is valid
    PromotionProducts (promotionId, itemId) = list of products on sale

    The synchronization logic is simply that all promotion tables must be synchronized just to the customers present in the PromotionClients table. So each select element for these tables of publication contains something like "... and there are (select 1 from c PromotionClients where c.clientId =: CLIENTID). It works fine until there are some changes in the PromotionClients table. After the change of PromotionClients table starts to sync, but other tables do not - there is in fact no updates on their respective folders.

    Is there a solution to this problem other than to manually create the triggers for the PromotionClients table that would execute model-update on each related table? I mean - is there an existing function in OracleLite that woud let set a few references - to load to a point of publication/table?

    And in the face of similar problem - there is also Promotions.datefrom/dateto limitation. Promotion tables must be synchronized at the time where actual date is between Promotions.datefrom and dateto. When someone modifies some of these values and so the promotion valid for the time related tables does not automatically update and so they do not start to synchronize. Just the Promotions table begins to synchronize. So we might need to implement another trigger to perform updates dummy on the tables of PromotionClients + products, Promotions.datefrom/dateto update.

    I do not like the personalized relaxation approach - it just duplicates the synchronization logic and it is inconvenient to maintain the synchronization logic in two places (pubitem selects + custom triggers). I would like to find a solution of OL-native - as referring to load tables for each publication element that would cause triggers to OL to also catch the person in charge of the lines of tables (which were not actually modified) to be marked as dirty and synchronized to the client. Is there a solution like this? Or is there an alternative better than custom triggers?

    When you trigger an event in a related table, it gets registered for PGM compose the data in this table. If there is a suspicion, MGP will compose the data in these tables as well.

    So if you have something like a REGION_MAPPING table that maps the users in various locations and if you change the table data and want other tables that are joined with him to compose the data, and then add a hint of dependency to the tables mapping them to REGION_MAPPING. If these tables is regularly updated and data are being composed for the child tables, then you don't need the trick, just good practice to add it.

    You're talking about using the free transform on a layer or an object?   With Image > resize the central position is irrelevant.

  • How to maintain the Illustrator pen tool race settings (size, brush, etc.) for any new route?

    I'm a newbie, so it's probably obvious, but I can't find it in the tutorials or documents.  In Illustrator, I want to keep the race settings when creating multiple paths with the pen tool.  However, whenever I start a new path, the time settings back to what should be a default value.  For example, I put 16pt + Variable + Basic and STROKE width profile path.  When I start a new path, return to 1 point + uniform + Basic settings, and I have to back to my original. Other art programs I've used maintain the settings of the tool used lately until they are manually changed.  How can I get the settings to stay through multiple uses of the pen tool?  Thank you.

    Hi Bion_s,

    In the framework of play in Illustrator for a solution, I found that if you open your appearance Panel (window > appearance), select the menu drop down and deselect New Art has basic appearance.


    I found that when this option is disabled, you can select your profile and the width of the line and shoot several times without him returning to the default line!

    Please let me know if it works for you. I don't know how it might affect your workflow on other projects, but it has led to the behavior that you seemed to want.
