HA Configuration questions

• 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.

• 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.

• Newbie on iSCSI Configuration questions

  Hello everyone

  I'm new to VMware. I have two questions

  (a) once I have add an address IP of SendTargets discovery, how can I update it? for example, if a new target is visible via the IP discovery after that it has already been added in VMware and I want it to appear.

  (b) is there a provision the disconnection of one specifying IQN (San identifier)? I went though VSphere Documentation and I couldn't find anything.

  (c) VSphere he iSNS support such as Linux (iscsiadm)?

  Thank you

  Welcome to the Forums-

  (a) you will need to go to the section of the configuration of the ESX host storage card in the client vSphere select initator iSCSI, then click Rescan - this cause a target command send sending sllowing to the discovery of new targets

  (b) No, there isn't a way to disconnect from a specific IQN I know

  (c) to the vSphere, I think not vSphere supports iSNS.

  If you find this or any other answer useful please consider awarding points marking the answer correct or useful

• 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.
  primary-
  OS - linux
  DB - 10.2
  data files - OMF (db_create_file_dest and db_create_online_log_dest_n)
  FRA is configured.
  archiving of FRA.
  
  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".

• 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?

  Helen

  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.

• Last good known Configuration - Question and problem

  Hi, I have a problem about the last good known Configuration. my computer has an initial problem and I managed to get rid of this by copying the file hal.dll in my windows XP cd. but to cut the long story short, now everytime I turn on my computer, it loads a different (or perhaps old/incorrect) configuration of windows and that the default configuration of windows has a problem and I put the cpu and the new. in order to ensure that it loads correctly, I have to press F8, choose last known good configuration and choose the right configuration. I do this whenever I start my computer now. I wonder if there is a way to remove the incorrect configuration or set the right configuration default so that I don't have to keep hitting F8 every time I start my computer? Apart from the replacement of the hal.dll file, I also replaced the boot.ini file by following these steps: http://pcsupport.about.com/od/fixthe...airbootini.htm

  Hi JulianLin,

  It is possible that some third-party programs installed on the computer is causing the problem.

  I suggest that you put the computer in a clean boot state and check if it helps.

  To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  See the link below to learn more about how to clean boot.

• New Network Configuration Question

  Out of my element here, have a new building we are evolving towards and want to check the right way to install our network. Rooms include 1 - TZ-200, 1 - LAN + Modem wireless switch dell 1-2824 (data), switch dell 1-2824 (voice), 1 - security DVR. If I configure the TZ-200 to the dhcp server, remove the dsl, taken in the wan port modem dhcp will be the sonicwall pick up the wireless and purge the IP for wireless addresses, as well as configure the remaining ports on TZ-200 LAN will all devices to be on the same subnet/nat for easy access? can provide simple schema, if that helps.

  Forget the feature wireless modem from your Internet service provider. You cannot have two routers 'work' (not in this configuration in any case). The only jobs of the modem is to feed the WAN in the Sonic and the Sonic is one that will manage all SonicOS is designed for, such as the creation and serving Dhcp. unless you are forced by the ISP contract to use the material they gave you, it may be more easy to get just a modem ADSL2 + regular that you can find in any * sale because they are unpopular with the houses of our days.

  To get WiFi in your network, you will fill a WiFi 'something' to one of the LAN in the Sonic ports. It can be of any router wireless of quality home set in Bridge mode (all DLink, Netgear, Linksys, etc, they can all work such as bridges), or a wireless bridge of commercial quality (as Unifi AP).

• 1200 AP configuration question

  I'll put up an AP 1200. If you go to > Network Interfaces > Radio0 - 802.11 g > settings, there is a setting for "external antenna Configuration. I use an external Hi-gain antenna. Can I pay this active? And if so, it won't accept the dbi parameter, though it seems to me be in the accepted range. Any help is appreciated.

  Hi Johnny,.

  In AP mode, it is not a requirement. My understanding of this setting, it comes into play in Bridge or WGB mode.

• SG500-28 2 switch battery Configuration Question

  I have two switches of port SG500-28 I want to setup as a stack for purposes of failover for a NFS storage device. The NAS will be on a LAN VIRTUAL (VLAN2) and the other VLAN (VLAN1) will be to users and the domain server. I'll put the configuration in place

  Each switch will have ports 1-6 & 13-18 years for VLAN 2 and 7-12 & 19-24 for VLAN1

  NAS NFS with team of network cards and an IP address of 172.16.10.10 on VLAN2, with on each card network goes to each of the switches.

  Server with partner cards network and one on with on VLAN1 192.168.10.10 IP address of each network card goes to each of the switches, users will be distributed on both switches.

  The cumulation function is quite simple and implementing VLANs through the ports is still simple, but I don't know if there are other parameters that I need to configure on the switch to allow the load balancing of server on both switches.

  Advice would be appreciated.

  Hi Biz365,

  I think you're missing link aggregation here for grouped on the NAS and Server NIC.

  The correct order would be:

  1. turn the battery - I assume you have already done

  2. set the OFFSET with LACP or without depending on the other end

  3 configure the logical framework of the channel/LAG/Etherchannel Port as access port for VLAN respective

  to check if everything is good to go use:

  1. display the battery

  2. display the spanning-tree port-channel protocols - to see if the OFFSET is operational as an interface

  3 see the mac interface port-Television address table - to check the VLAN function

  Kind regards

  I see cisco samples configurations include an access list entry as follows...

  I understand the purpose of the ACL above regarding the test configuration that I posted here.

  Let me explain.

  LAN - router - WAN - router - LAN

  Communication between the two LANs can be on a GRE tunnel to an IPsec tunnel or IPsec/GRE tunnel.

  If you simply want to communicate between them unicast IP traffic, IPsec is recommended because it will encrypt the traffic.

  If you need non-unicast or non - IP traffic through, then you can create a GRE tunnel.

  If you want IPsec encryption for the GRE tunnel and then configure IPsec/GRE.

  The ACL you mention will not work because the GRE traffic is only between tunnel endpoints.

  The traffic that flows between local networks is the IP (not the GRE traffic) traffic where a permit GRE ACL will not work.

  It will be useful.

• IAAS configuration question - database SQL

  I have questions, get the IaaS of vRA setup part.  When installing, I get an error message saying 'domain user iwic\vra.svc is invalid or the database to access denied.  Validation error 1385. "This has occurred trying to connect to a SQL cluster and with a local installation of SQL on the server of IaaS.  I excluded the problems of firewall, ensure that the vra.svc has full right to SQL server, verified password admin and correct username.  At this point, I'm stuck and looking for help on getting this Setup is complete.

  

  The issue ended up being with the port number of the SQL instance.  The port number for this instance of SQL changed and I do not have this information.  When I was with SQL Management Studio to connect to SQL server, it requires a port number during installation of vRA you must know the correct port of the SQL cluster number.
