• Network configuration question

  I'm one of our 5.5 hosts replace with new material and want to make sure that I get the right networking. We have unit vcenter and a HA cluster with shared on an EQ San storage and complete double switches for redundancy. My old hosts have 2 quad port NIC, so configure each vswitch with double vmnic for a total redundancy was easy - I split each pair on the physical network interface cards. If one of the physical network cards is dead, I was still all my connections.

  The new host has 1 quad port nic and dual 2 network cards to port. Network interface cards double port match and have tcp offload capabilities, but the quad port does not. I want to use the dual port 2 for my iscsi and vmotion, so that leaves the quad port for my public connections. What happens if the public NIC dies, especially if they vcenter on this host? I know that all the virtual machines will still work, but will they automatically vmotion to other hosts if only the public network fails?

  Thank you.

  NIC failures are very rare. So, I would place too much emphasis on this scenario.

  Is the answer to your question, it depends. HA has a configuration option called isolation response of the host, who controls what happens when the host loses connectivity management. By default, it is configured to leave it powered on. You can change it to Shut Down, which makes sense in your scenario, as the loss of connectivity management means the loss of connectivity to the virtual machine as well. And in this way when management network goes down all your virtual machines is gracefully closed and restarted on another host.

• ESX iSCSI Configuration recommendation

  Hello

  I wonder what is the best configuration of the storage card in the following scenario to provide a NIC host and SAN controller redundancy. The SAN must be directly connected to each host that I don't have one at the moment gigabit switch, which means each link point to point in its own subnet as below.

  Host 1:

  iSCSI_A1: 192.168.1.2/30

  iSCSI_B1: 192.168.1.5/30

  Host 2:

  iSCSI_A2: 192.168.1.9/30

  iSCSI_B2: 192.168.1.13/30

  ISCSI SAN:

  A1 of the host: 192.168.1.3/30

  B1 the host: 192.168.1.6/30

  A2 of the host: 192.168.1.10/30

  Host B2: 192.168.1.14/30

  According to the article, VMware KB: considerations for use port binding software iSCSI in ESX/ESXi, I should not use links in Port because each link is in a separate broadcast domain. Does this mean that I have to put up 2 iSCSI adapters on each ESX host software and just use the dynamic discovery?

  Thanks for any help.

  Of course, no problem. Make sure you see both paths, under Configuration-> storage adapter-> select your iSCSI adapter. Example like this. In this case, I have 12 aircraft 24 channels, so 2 paths to each device (LUN).

• Need suggestion for storage on the server ESXi5 iSCSI configuration

  Hi friends,

  I am new to vmware & I want t know if I have physical iSCSI card installed in my ESXi 5 & it connect directly to the server and then again I want to configure virtual SCSI for connection to the VM card? If so, why?

  Thank you and best regards,

  Pradip

• Software iSCSI configuration

  Where we get number IQN that we need to manually enter static configuration of the software iSCSI discovery.

  It depends - some have the ability to not be discovered. Give it a try, in case of doubt. If this does not work, then you will need access to the management interface or know someone who can.

• ISCSI configuration

  Hello

  I'm initiator configuration iSCSI on my ESXi 5 host software. I use the Dell PowerEdge r.620 server.

  How are iSCSI Broadcom cards will be copied into the storage card from vCenter Server view.

  At the moment I am unable to see any adapter storage Broadcom for the "storage card". I did all the steps below.

  (1) VSWITCH CONFIGURATION

  (2) standard vSwitch Configuration

  (3) add the VMkernel iSCSI Ports

  (4) ports VMkernel associated with physical cards

  But I am unable to see the storage card BroadCom for the "storage card".

  Please suggest.

  You won't see this map appears in the list of storage adapters. It is listed in the HCL as network.

  

  Enable iSCSI Software adapter, get properties for it in the list of storage adapters, and then configure the networking from there.

• HA Configuration questions

  Probably a simply and silly question but...

  I'm having a problem with HA on one of my groups.  At the cluster level, I have a message indicating ' insufficient resources to meet the HA level of failover cluster < name of the cluster > < name datacenter >.»  Failed to contact a senior officer of HA cluster < name of the cluster > < name data center >

  Each of the 6 guests in the show cluster has an error with the HA Agent on < Home > cluster < cluster name > < datacenter name > has an error: error when running script control of health.

  Now, looking at them HA at the cluster level, see someone (many ahnds in the kitchen I guess) enabled DPM under admission control.  I disabled that so that it matches my other clusters that are precisely be works very well.  I selected "reconfigure HA" on all hosts, but the process fails. "Cannot complete the configuration of the HA agent on the host.  Impossible to contact agent HA primary. »

  So I think that if I just disable HA on the cluster and back depending on who he might rectify the issue.

  2 questions:

  1 will be solve my problem

  2. If #1 will be, shutting down HA affects the virtual machines running on 6 other guests that endangering temporarily?

  Thank you

  Casey

  Deactivation and reactivation HA on the cluster will probably fix the problem.

  See here: http://kb.vmware.com/kb/1021173

  And you should do this as soon as POSSIBLE, because NOW your virtual machines are already vulnerable, because HA currently does not work properly.

  Turning off HA and will not affect the virtual machines in any way, except to put them at risk of not be restarted automatically in the event of a host failure.

• Configuration questions

  Hello

  I'll put up a new configuration to increase the availability of the virtual machine

  I have a 3.0 license for 4cpus ESX Server that manages all the vm I

  What I wanted to do is setup in the image below

  The virtual machine (about 6) is stored on NAS1 and their management divided by 2 servers

  NAS2 is synchronized with nas1 (with rsync)

  If a server goes down, another one will manage the virtual machines.

  If a NAS fails, I'll use the virtual machines on the other.

  My questions are these, if you guys could please answer none of them I appreciate it:

  (1) ESXi will run on a quadruple-heart machine even if its license is for 2 cpu or will it does not at all?

  (2) is there any compatibility issue on moving the virtual machine on the esx 3.0 Server server esxi 4.0?

  (3) can I synchronize two SINS while VMS are running?

  (4) do you think that any problem with this configuration?

  Bye,.

  uilli

  > 1) Will run on a machine four hearts, ESXi even if its license is for 2 cpu or will it does not at all?

  Licence is issued for sockets, no carrots. So 1 quad core CPU needs 1 license.

  (> 2) is there a compatibility issue with the movement of the virtual machine on the esx 3.0 Server server esxi 4.0?

  N °

  (> 3) can I synchronize two SINS while VMS are running?

  Best way is cold migrate virtual machines to the new data store. In fact, it is the only way.

• How data travels in the iSCSI Configuration

  

  Hello

  I'm a little confused about how DATA moves through an environment of VI3.5 using iSCSI SAN.

  Before, I am attaching a schema, so everyone will be on the same page.

  It is a scenario with two servers ESX (ESX1 and ESX2), a physical server (Server1) and 4 Virtual Machines. (VM1 ~ 4)

  vmnic0 is for traffic Service console and the virtual machine.

  vmnic1 is for vmotion, but on the same subnet that are Virtual Machines.

  vmnic2 and 3 are for iSCSI and Service console for iscsi on a different subnet and different switch.

  The example is for the understanding of the performance and the communication network and not for security reasons.

  I know that when you want to use VMotion and HA, you need to use Shared Storage (IE iSCSI SAN) and your virtual machines are stored on the SAN.

  Here are my questions:

  1 - is this correct design?

  2-if I want to copy a VM1 VM2 to file, how data moves? (knowing that both are stored on the same SAN and they are both on the same ESX Server)

  3-if I want to copy a file from VM1 to VM3, how data moves? (Knowing that both are stored on the same SAN but they are on different ESX servers)

  4-if I want to copy a file to the server Server1 to VM1, how data moves?

  5 - If you do a VMotion VM1 from ESX1 ESX 2, how data travel? (I know for VMotion the contents of the RAM to the virtual computer will be copied to the second serve of ESX) This will affect the performance of the local network?

  6. What do you recommend to monitor traffic on vmnic?

  Please include the question number in your response.

  Thank you

  1 - is this correct design?

  OK for iSCSI.

  But you do not HA hat on the breakdown of the network cable or the NETWORK card (for the first 2 vswitches).

  It is good to have iSCSI separated by VM and VMotion, but usual for each vSwitch to give at least 2 cards of uplink.

  You can for example put VMotion and VM on vswitch, using 2 NICs and affecting a NIC preferred for the virtual machine and a preferred (different) for VMotion NETWORK card.

  2-if I want to copy a VM1 VM2 to file, how data moves? (knowing that both are stored on the same SAN and they are both on the same ESX Server)

  VM1 and VM2 could talk via the network of the VM.

  So VM1 get data from the vmknic2/3 (if is not in the cache of the comments), copy to network (vmknic0), VM and then store the data (and goes to vmknic2/3)

  3-if I want to copy a file from VM1 to VM3, how data moves? (Knowing that both are stored on the same SAN but they are on different ESX servers)

  Same as before, using 2 ESXs

  4-if I want to copy a file to the server Server1 to VM1, how data moves?

  vmknic0, then vmknic2/3

  5 - If you do a VMotion VM1 from ESX1 ESX 2, how data travel? (I know for VMotion the contents of the RAM to the virtual computer will be copied to the second serve of ESX) This will affect the performance of the local network?

  vmknic1

  6. What do you recommend to monitor traffic on vmnic?

  You can use the tab Performance on ESX.

• Boot from SAN Configuration Question

  Asked me to start deloying new hosts ESX 3.5 using Boot from SAN.  All the documentation I've found is clear on the configuration of HBAS and SAN lun.  I tried to find out what the correct design for the HBA boot ports and storage used.  Does anyone have info on the Boot/operating system as well as the storage of data on the same HBA ports.  This design would be only two HBA by using a port of each for failover.  I also plans to isolate the boot/OS on his own two redundant ports but get resistance from my SAN Group on the fact we use two additional ports turned on by host.  After a few unsuccessful attempts with VMware support, I finally got someone to give me one different answer a document on how to put in place the HBA and SAN.  I was told that sharing should be fine but I also met some files indicating that you must keep them separately.

  Hello

  There is no question share the wwn for a startup process.

  The key here is to always book LUN 0 for the reader to boot/OS on all systems.

  I have 12 guests thanks to her, and there is no sound technical reason to isolate him.

  Kind regards

• remote server configuration question

  Hello
  
  I have my web app works fine on a local apache/php/mysql server. but now I'm doing work on the remote server. so far, no luck. a few questions:
  the connection to the base for my local server has a user id and password. can I use the same username and password for the mysql database remote?
  I understand how to connect the db to the apache server locally (I use port 8080), but I don't understand how the apache finds the right mysql database on the remote server. do I have to use the db connection in the application of dw Panel and modify the connection settings somehow it can therefore be used for the remote server? I noticed that I get an error: the requested URL doglist.php was not found on this server.
  
  Additionally, a 404 not found error was encountered while trying to use an ErrorDocument directive to manage demand.
  Apache/1.3.37 Server at www.counselorone.com Port 80
  
  Thanks in advance for all advice.

  David and Gareth Murray.

  Thanks for your help. The last piece was dense enough to me, but I got it. David, I know that you deal with in your book, but you could probably devote a special section, its that delicate. The nuts and bolts of what I've done is...
  1. to develop my unconscious site at the remote server, including making local database connections. Because microsoft IIS stored in my own way, I changed the port of Apache on 8080. After reading David's comments, I think that its smarter to simply not bother to change the Apache port and manually turn off the IIS application. OR, you can go back once you have created the site and edit your config file Apache backwards to port 80, because you will need the localhost, not localhost: 8080 to connect to the remote server. To avoid pulling the hair, just to deal with the default configuration of apache on port 80.
  2 hire a remote hosting company. I use the server range, although I have not been with them long enough to give a thumbs up or thumbs down.
  3. put the local site on the remote server. I used public_html to store my files.
  4. download the remote server to connect to the database. This last part seemed to require a few things, which were not obvious. Following the advice on this forum, I went to the remote site and note the username, password and database name. (these are NOT the same as my local site). I then copied/renamed my database on the local site to match with the prefix than the remote server has put on my remote database. For example my db was named test1 locally, but the server named wwwcoun_test1, so I renamed it which.
  5. I tried to establish a connection to the database with the new names. It worked. my understanding is that everything we try to do here is set up the connections correctly. you're dealing with loading data in the database with phpmyadmin, a great time-saving tool.
  6. I went on site remote and typed in the url for files downloaded to see if they would connect to the database. they did it.

  That's all. Hope this story helps the next person who needs help.

  Yet once again, thank you very much to those who responded. I appreciate your support.

• DataGuard configuration question.

  I need suggestion about the configuration of the dg.

  OS - linux
  DB - 10.2
  data files - OMF (db_create_file_dest and db_create_online_log_dest_n)
  FRA is configured.

  Backup site.
  OS - Linux
  DB - 10.2
  already have a stand-alone single instance running on ASM. with two DATA and FRA
  
  So my question is can I create instance watch on ASM?
  primary means no EAM with omf and Eve on ASM for?
  Please notify. Thanks in advance.

  You can... but I wouldn't... and here's why. Assuming that, even if you did not, it is not logical and physical.

  The point of the physical standby, is that it is 100% identical to your production by all means server. Shell scripts, run on one should run without modification or other tests on the other. It is the same for all aspects of infrastructure. Make it different and you invite problems or need to up on all aspects of the tests.

  In case you, to all the less, your upgrade paths, and other names must be different. Of course, I would move one spfile to another.

  Why not move the primary to ASM, and then to implement the strategy of DR?

• Airport Extreme - static IP configuration question

  Question: AT & T has us on a range of public static IP address xx.xx.xxx.33 - 38 (six addresses). I already put in place with the gateway, subnet. But I need the Airport Extreme to provide more than just 6 addresses to support all of our devices. Is this possible and if yes, how I have set up?

  Attempted solutions: I tried to expand the DHCP range manually in the settings of the utility. I changed it to 10.0.214.33 - 38 (which was the default range) to 10.0.214.30 - 39 to see if this helped more devices, but she did not.

  Help, please! Our business leaders are coming and I need to have this resolved.

  Thank you

  The key is that Apple routers are designed for general public use. They don't have many options when it comes to commercial applications. You better get a router that provides these additional features. I recommend that you consider the research in routers of professional level provided by Cisco (or similar) for this purpose.

  None of the available options, provided by AirPort Extreme, will be able to satisfy your needs network entirely.

  For example, you can use the network > router Mode to 'DHCP' option only This would use a public ISP IP addresses for the base station and to distribute the five for customers... other required network, but you will not be able to use this setting to distribute IP addresses private network customers remaining, as this option disables the service NAT on the base station.

  Will on the other hand, using the NAT and DHCP option would take care to provide for the remaining machines, private addresses but allow only one device is accessible with a public IP address by placing the appliance in a DMZ. Apple calls this a "default host".

• Newbie on impregnation test question to

  I pray to God that I am not violating any term request this. I received an invitation from dipping to participate with a link to a survey. I finished it and after, he said I'm probably would participate. It was 3 days ago and I have not heard anything since. Having never done this before, I'm insanely curious if there is normally a 4-5 day wait... If I did something wrong or if I just wan't selected. Please understand that I was eager to hear something that I want to participate!

  I understand that it is taboo to discuss the test, so I wasn't sure if just ask me these questions would create problems. Yet once again, I never did (only got my Photon 10 months) so I do not know the procedure.

  If this post is prohibited, mods/admin please delete or let know me, and if I can, I'll remove it.

  Thank you!

  You have nothing to fear. There is a bit of wait times with different parts of the test of impregnation.

  Just keep in mind that soaking tests are like Fight Club;

  And the first rule of Fight Club?

  All in good time.

• Z51 - initial set-up configuration question - please help

  This seems to be c reallysillyquetion b I'm nowhere fast.

  I tried to start using my new Lenovo Z51 but I can't go beyond where it says "help us to protect your information.

  I selected a different email for a security code to send to account.

  Then he said: "to verify that this is your email address enter below and click 'next' to receive your code.

  So I got my windows account email address - you click on "next" and get to the next screen

  The next screen has message saying "enter the code you received - if * is the address of e-mail on your account, we will send you a code."

  But I do not get anything - so when it asks me to enter my e-mail address means enter the same address that I chose to have the sent code, rather than my windows email account?

  Please can someone help save my sanity?

  Mod edit: System model added to the subject line to improve visibility / clarity

  Ignore my question - after trying both options again, I actually sent the code, able to move to the next step. Hoping that there are no more problems.
