• Config network initial ESX with iSCSI SAN

  Hi all

  I want to install 2 ESX 3.5 servers which will be connected to an EqualLogic iSCSI SAN.

  The SAN is on a VIRTUAL, 10.x.x.200 with a 255.255.255.224 LAN Gateway.  This VLAN is not routable, DNS servers, etc.

  What I am trying to understand, it's for the initial setup of ESX, when I set the config network (console), should I register the IP address for the VIRTUAL LAN, example was:

  IP address: 10.x.x.201

  Gateway: 255.255.255.224

  Primary DNS: white

  Secondary DNS: white

  Or, for example B, should I use our 'public' speaking:

  IP Adress:129.x.x.201

  Gateway: 255.255.255.0

  Primary DNS:129.x.x.1

  Secondary DNS: 129.x.x.2

  I know that with the VIC, I can later add vSwitches, etc., but at least for the initial installation, I want the configuration to provide smoother operation. Thanks for any idea that you can provide!

  Hello and welcome to the forums.

  What I am trying to understand, it's for the initial setup of ESX, when I set the config network (console), should I register the IP address for the VIRTUAL LAN, example was:

  Use example B (129.x.x.x) for the Service Console (management functions), and after that the system is in place to add an another vSwitch used to connect to the SAN VLAN.

  Good luck!

• LaseJet 1102w more airprinter issues as well as config network home

  I have HP Laserjet 1102w printer in my network as follows:

  192.168.1.1 modem ADSL in my room--> 192.168.1.2 TPLINK TL-WR941ND in my room--> 192.168.1.3 TPLINK TL-WR1043ND (AS A REPEATER) in my office to another floor of my house. The printer is in my office.

  The printer works fine using my laptop. I can print everywhere.

  But when you try to print from an Ipad or an Iphone, I can't print from my room. No printer does appear in airprinter (ipad/iphone).
  When the two ipad or iphone gets Repeater (away from 192.168.1.2 router TPLink) your printer in the airprinter
  So I can not print from my room when using ipad/iphone.

  What I am doing wrong?

  I would like to print all over with my ipad/iphone. Y at - it a config to 192.168.1.2 router?

  The printer has static IP 192.168.1.11

  Thanks in advance.

  This is because the printer and iOS devices must be on the same network, if one is on the primary and we're on the Repeater, it probably won't work. As I have already mentioned that AirPrint often does not work on repeaters or sensitive areas because of the way they interact on the network.

• Troubleshooting an issue of network ESXi

  I've done memory up gradation of a virtual machine and power, it works in a different ESXi in the same cluster, who do not have virtual machines.

  The virtual machine is not the ping requests, but able to access by using the console.

  However, the virtual machine is on the same switch distributed in the two ESXis.

  When I turned on in the old ESXi, it pings fine.

  No possible explanation?

  However, the virtual machine is on the same switch distributed in the two ESXis.

  In this case I would start checking the host's physical network connections and the physical switch settings, i.e. the tag/untagged, allowed VLAN...

• Two networks, ESXi Server?

  We have two server VLAN in our environment (99 and 30). The 99 (10.99.x.x) is old and slowly be phased out and machines are moved to the 30 most recent (10.10.30.x). I also work on an upgrade to VMware infrastructure. We have a mixture of former host ESX 3.x and 4.x and ESXi 4.1 will visit. (I'm also relatively new to VMware so forgive my ignorance). My question concerns the following scenario.

  Host 1 is on the LAN 10.10.30.x and a few machines running. I need to do an upgrade on this host, but first migrate the machines off.

  Host 2 is on the LAN 10.99.x.x but we want the version of ESXi. I'll use this as a waiting area for machines while their hosts are upgraded. There are 2 NETWORK interface on this host card, NIC0 is configured on the VLAN 99 with management related to her network. I created a second virtual switch and he attributed to NIC1. This NIC is connected to a switch that has the switchport configured on the VLAN 30.

  I'm lost what to set up then. (Maybe nothing) Perhaps I am confused because I had to put an IP address on NIC0 (network management). I have to NIC1 IP with another network management? I would stay on the 99 VLAN NIC0 and NIC1 to be on VLAN 30 so when I transfer machines to the host, I can configure just the appropriate VSwitch so I don't have to re - IP them.

  Welcome to the community,

  virtual networks are not very different physical networks. The IP address you assign, is assigned to the management of ESXi host, not to the NIC itself, it is not necessary to attribute the anthers IP address to the other network adapter.

  What I recommend is that you plan to configure the network using the VST host, i.e. configure physical ports as junction (for Cisco) ports or ports (for other providers) tag and assigning the VLAN ID on the groups of individual ports. In this way, you can use a unique vSwitch with two uplinks connected for a better distribution of redundancy and load.

  See for example http://kb.vmware.com/kb/1004074

• iSCSI, vmotion creating separate network, ESXi

  Hello

  We have purchasd EMC SAN NX4 which is iscsi.  We have also 3 ESX server, we have installed ESXi on them.  My question is, in this version, I can create two types of connection a connection of the management and the other is vmkernal.  As I understand it the vmkernal is used for iscsi, vmotion, and NFS.  VMware told me that all this can be on the same network.  VMware tells me that if I quick vMotioning much something is not so generally for vmotion traffic is light.  Technology EMC says something different, he says that vmotion and iscsi connections should be different network.  So I'm a bit confused.  Please let me know what is the best way to proceed.

  Thank you.

  It depends on how many resources you have available on your ESX servers. If you have only 2 NIC card then you can not sperate VMotion and iSCSI. But recommended say seprate LAN, IP LAN, LAN seprate Managment seprate Storage VMotion. (includes failove)

  Now its up to you and your information TECHNOLOGY budget. These days LAN cards are pretty cheap so you can put more card and easily separate traffic.

• Networking ESXI establish two vswitches and 2 NICs on different networks.

  OK hope someone has an idea.

  Have two network cards and just connect the second network card but my setup requires that the first NIC physicle

  10.10.0.0 network, 255.255.255.0 subnet, Gateway, Vswitch 10.10.0.105 0.

  the second nic physicle

  100.100.0.0 network, 255.255.0.0 subnet, 100.100.0.1 gateway Vswitch 1

  I need the machine virtual first Vswitch network and some on second Vswitch network.

  At the moment I don't see how to set the ip address of the second network card or the gateway?

  Is there a way to do this?

  I have the updated Vswitches in place ok and network adapters are attached to the different vswitches.

  When a physical NETWORK card is assoiciated with a vSwitch, he is forced to behave like a shared on a physical switch port. However, there is more no uique to the physical NETWORK adapter configuration. It passes the traffic of the VMs and the core of the virtual machine to the physical network as an uplink. MAC addresses and IP addresses inside the frames come from virtual NICs attached to the virtual switch.

  You define IP addresses and default gateways within the virtual machines and any VMkernel ports connected to the virtual switch.

  Another way of thinking, is pretending the ESXi server has swallowed a bunch of switches and cards network is now the switch ports. You connect a box full of switches to your physical infrastructure, not a 'normal' server

• Change config network on Photosmart C4385

  I have a Photosmart C4385.  I recently changed my router and dhcp addressing.  The printer still has the old (its URL and the gateway) IP addresses, and now the interface of the solution Center tells me "this product is not configured for networking."  No network settings are available. »

  Short to reconfigure my router, is it possible to set the printer to the factory settings?  Or to force the printer to re - acquire its DHCP?

  Printer is connected to Vista Ultimate Svc Pk 1 USB, but I have other computers (including MAC) who needs a wireless connection, but cannot 'see' the printer broadcast Configuration.

  I use a Belkin wireless router that is configured for DHCP from my VPN Firewall-Router Netgear.

  The old system used 192.168.2.XXX

  New addresses are 192.168.130.xxx, gateway is 192.168.130.1

  Yes, with WEP SSID

  I think that covers everything he... Sorry for the re-post - I read the post of good Questions repeatedly.

  Message edited by sw33n3y on 02/28/2009 10:27

  Best thing to do is to set a static IP address on one of your computers to 192.168.2.76 (same subnet as the old IP address of the printer) temporarily and to reconfigure the IP address of the printer on the new subnet that you use.

  You can do it from the printer's internal web page.

  When your done, reset IP address of the computer to the new subnet address.

• How Config Network Service by script? for example the response file

  I created a batch for DB creation using DBCA silent.

  I want to add a script to create also the Networking Service after.

  I was told that it can be done with the answer file.

  Is a response file script also which can be run after the DBCA scripts?

  Where can I find a manual with the available commands so I can produce what I need?

  On the internet, I don't find as silent examples of the DB instalation.

  EDIT

  Operating system is Windows 7 Oracle 11.2.0.1

  I want to create the Network Service that will add these lines to the tsnames.ora.

  DBNAME =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP)(HOST = wsName) (PORT = 1521))

  (CONNECT_DATA =

  (SERVICE_NAME = dbname)

  )

  )

  on the client and the server.
  How can I automatically via a batch script, to add it to the DBCA scripts after creation?

  I was told once to atopic that this could be done via a response file.

  I provided the Correct found answer on this subject since then.

  The 1st solution to set up a NetService via a custom command script, adding the data you need as if it was a BAD IDEA.

  1. you can not guranaty the correct paths if you plan the planting in an API with a lot of end users.

  2. the 1st time, you set up a network service, it must be set to cause netca (network Assistant) 1st the tnsnames.ora is not exiswt at all.

  THE OFFICIAL is to run from a shell in silent mode netca and feed it with values from a response file, either online as parameters

  I copy paste the solution I wrote on a separate thread

  https://forums.Oracle.com/thread/2559659

  The scenario is to set up a typical network Service without using the interface graphics, but instantly with a command from the shell.

  Scenario took place on Oracle 11.2 g on Windows 7

  Level of Description: Noob

  1. you can open of Network Setup Wizard, of the hull directly by entering its name "netca.

  Info: netca is an actaully of batch file calling several "elements". Located in the \bin folder of the directory of Instalation Oracle (Client and server time)

  the patrh of the \bin folder, where is the netca is included in the widnows PATH environment variable. So when you enter netca there and run it.
             https://en.Wikipedia.org/wiki/path _ (variable)

  ATTENTION: If you have the path of the directory before the path of the Client Server, the server netca will run instead

  2. on a typical NetService we re Protocol, host, Port, DatabaseName and the name of the service itself to identify it.

  -Silent option along a response file gives the possibility of is not interact at all with the GUI as all values will be filled with the answer file that will point us

  3. you can find an example of response file to the ORACLE_HOME\inventory\response\ called netca.rsp. It contains all the possible parameters, you can pass, so that you can choose that you need.

  For our scenario, the final answer file will look like this.

  [oracle.net.ca]

  INSTALL_TYPE = ""custom"

  NAMING_METHODS = {"TNSNAMES"}

  NSN_NUMBER = 1

  NSN_NAMES = {'DBNAME'}

  NSN_SERVICE = {'testII"}

  NSN_PROTOCOLS = {'TCP; PCNAME; 1521 "}

  So now you simply enter netca responsefile option along the pat of the answer file with the silent command to power entry

  NETCA/Silent /responsefile /C:\oracle\product\11.2.0\dbhome_1\inventory\response\mynetca.rsp

  So simple

• Config network and VLAN

  I inherited a network in a colo data center.

  Current network has a Dell 2724 switch in unmanaged mode. Servers using the 192.168.195.0/24 range.

  A new facility will be 3 vSphere, 2 Dell Equalogic PS4000 hosts and 2 Dell 6224 switches for redundancy.

  The 6224 are segmented into VLAN.

  The new configuration was to use the beach of 192.168.196.0/24.

  VLAN 205 receives data from firewall to the camp and our 2724 switch.

  On the 6224 2 port goes to the old switch 2724. He is member of the VLAN 205 and 405 defined on Trunk, AdmitTaggedOnly.

  ports 3-11 are designted for network traffic from virtual machines and are members of the 405 VLAN defined on the access, AdmitUntaggedOnly

  We now want to virtualize the old servers on the new ESX hosts.

  If I put the IP of my VM to 192.168.196.xx, everything is good, I have full network connectivity.

  If I set 192.168.195.xx, I get no connectivity at all.

  I see no connection of IP range in configuring VLAN.

  I need to be able to transport the two beaches of 3-11 ports, because at this point, I can not change the IP addresses of the old servers.

  What Miss me?

  Allow several VLANS on the same ports of physical switch, you must configure these ports as junction ports switch, which allows the two VLANS. 205 and 405. On the ESX host, create two groups of ports on the vSwitch 'Virtual Machines' - one for each VLAN - and define the appropriate VLAN ID. It's called Virtual Switch Tagging (VST).

• Backing up the Config of ESXi. Files

  Hello

  Is there a good method (if any) to back up the configuration of a hypervisor files automatically?  Ideally I'm looking for is a way to restore all changes "custom", I did a hypervisor in the present case, I have to rebuild a (recovery) disaster.

  You can use the script Perl esxcfg - cfgbackup.pl of the to do. Check out this post for more information on how to do the PowerCLI.

  Note: YMMV since I have not done personally.

• Config network for SAN traffic

  Please see the image as an attachment. It is what I currently have, the one after is what I think I need to do.

  Here's my number; I think I have install the networking incorrectly for my esx boxes hit the SAN.  For now, it's that everything works fine, however I think I may have made a few extra STREP that does not need to do.  Right now I have a NIC deticated to two different vSwitches which are useless, but SAN traffic.  the more I watch this, more I think that I should have used a unique vSwitch on every box of esx and just added the necessary ports console and core it.  So I would have a unique vswitch on each box dedicated to SAN traffic, each vSwitch would have two network cards current with both console and two ports of kernel.

  Maybe I'm just beating a dead horse because they're all going two do the same thing, but maybe it's something smarter and simpler to go with scenario after since they can load the balance between the two and failover works better.  ???   My biggest concern is, can I have two console different and two ports in different kernel, both on different subnets, to the same vSwitch?

  Thanks for any advice.

  Yes, your thought is good. having two NICS on a unique vswitch will give you more options for failover and load balancing. Having also several ports console and kernal on the same vswitch is not a problem.
