• EqualLogic group member network configuration error: "management interface should not be on the san subnet.

  Hello

  We currently have new EqualLogic 6100 device with this network configuration:

  Director of the IP - 192.168.0.2 (VLAN1).

  Member network config:
  eth0 - 192.168.0.3 (VLAN1)
  eth1 - 10.10.10.3 (VLAN2)
  eth2 - 10.10.10.4 (VLAN2)
  eth3 - 10.10.10.5 (VLAN2)
  ETH4 - empty

  I would attribute 192.168.0.4 to eth4, but received the error: "management interface should not be on the san subnet.

  I am sure that all interfaces eth has access to the VLAN1 and VLAN2, mean error indicates that eth4 should not access VLAN2 and only access the VLAN1 on the switch?

  Or eth0 should also have access to the VLAN2 only to reconfigure eth0 and eth4?

  Thank you

  > The group eating IP should be in iscsi VLANS?

  Yes!

  Note: If configure you an EQL it will ask an iSCSI port because nothing is more necessary to bring it up. The doest previous EQLs have a dedicated Mgmt Port and later, you can convert the last ethX as a MGMT port. This is the reason why configure you ISCSI at the beginning. (Think of a mixed group of newer and older models, and you get a picture)

  OK... once again it is the one and only member of the Group and there is making the production host connected to the right?

  The change of IP address, to a 3rd. subnet for temporary use.

  -Do not touch eth0-3 and the IP address of the group now

  -Configure the MGMT port and IP address management in the tempr group. Subnet. Use the Config-> Adv. Group-> network MGMT. You can change the MGMT Port of the Member, and the address IP of MGMT

  -For the registration of the configuration, you will lose access. You must place your admin PC in the templ. subnet so

  -Connect to the GroupMgr with temp again. INTELLECTUAL PROPERTY

  -Now you can change the IP address of group 10.10.10..x

  -Now you can change eth0 10.10.10.2

  -At the end, you can change the address IP of the Group MANAGEMENT, as well as the MGMT Port to 192.168.0.x

  -Change the IP address of your admin PC rear

  A failover, you should consider to hang a serial cable the active controller of the EQL. Use 9600,8,1, N with your favorite terminal program (putty.exe on windows). All the steps, you can perform from the command line.

  If this group and the only member not in production, but you can reset the config and restart from the beginning.

• Hyper-V and iSCSI network

  Hello

  We evaluate a migration of vmware for hyperv.

  I try to understand best practices for networks iSCSI comments.

  I have physical 4ports 1GBit dedicated, on the host for iSCSI traffic.

  I like to use all 4 for iSCSI host (vhdx volumes) traffic.

  Now I thought to do 2 of them shared by creating 2 logical switches in VMM, adding 2 virtual network cards for the host to use.

  The new virtual network cards are 10 Gbit. I don't see an option to change them to 1GBit. To me it seems now that the system prefers the 10 GB adapters. My other two physical cards are no more used.

  I tried to do all 4 ports as virtual, but somehow the 4.7EPA ASM does not see virtual cards. He said only: "no network adapters don't find" at the opening of the MPIO settings.

  Should I just ignore this idea to share and use 2 for host and 2 for iSCSI hosts, or is it a medium work?

  It is recommended to devote at least 2 interfaces on the host iSCSI network.  In addition, you must install the Dell EqualLogic for Microsoft host integration tools and install the MPIO feature.  To enable the MPIO in the guest operating system, you must create at least two virtual switches that are related to the physical SAN on the Hyper-V host adatpers.  Virtual machines must be configured with at least two of these virtual switches.  Then, since the guest operating system, configure interfaces with IP iSCSI network, Subnet, etc...  You must also install the Dell EqualLogic for Microsoft host integration tools and functionality MPIO DSM in the guest operating system, if it is not running Windows.  If you use Jumbo frames, ensure that all NETWORK adapters used for iSCSI (NETWORK physical cards, NETWORK cards, Guest OS NICs) are enabled for frames.

  In regards to ASM v4.7 EPA you don't see not cards network for MPIO - there is a known ASM / ME v4.7 bug in Windows Server R2 2012 linked to the EPA.  It is likely that the configuration of MPIO is fine (you can check it out through the initiator Microsoft iSCSI MPIO EqualLogic tab - it's just that ASM / me has a problem of information display.)  This bug has been fixed in version recommended to v4.7 GA HIT/Microsoft - which is intended to be published very soon.

• Adding the iSCSI network switch

  Hello

  We have an iSCSI network for guests of vSphere 5.1 EQL boxes. The network is 192.168.0.0/24, we use the switches PC5548 and we have three groups EQL. Everything is configured following best practices from DELL, and everything is kind of okay job.

  Since we are affected by the poor performance of our SQL servers virtualized and troubleshooting led switches as a guilty suspect I want to try to use other switches to know.

  So I intend to add a pair of parallel to the PC5548 cisco switches and connect a host and a group of PS to those (where the SQL VM reside) and see the difference, but my question is that I can use the same network 192.168.0.0. / 24 although cisco and dell switches are not physically connected. VMotion work?

  You shouldn't use the entry level switches with 10 tables. The interlink trunk has 80% of eql bandwidh. You can consider buying Dell Force10 switches with buffers of large size and low latency.

  Kind regards

• Best practices for network configuration of vSphere with two subnets?

  Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

  Install the most common iSCSI would be traffic between hosts and

  the storage is not being routed, because a router it could reduce performance.

  If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

  MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

  vMotion a deployment scenario might be something like:

  NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

  standby

  NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

  NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

  NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

  VMK (192.168.4.10) active

  You would place you on VLAN 10 storage with an IP address of something like target

  192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

  gateway configured in ESXi would be the router the VLAN 20 with an ip address of

  something like 192.168.2.1. I hope that scenario help set some options.

• ESXi 4 - nic network configuration

  Hello

  I was wondering if I could get some tips here...

  We are currently in the early stages of planning our move to esx esxi and I am struggling a bit with the network configuration.

  I want to have failover and and teaming and whatnot, but I only have 4 cards to play with...

  Here's what I need

  The VM network

  Management network

  vMotion Network

  iSCSI network

  ISCSI does not need to have 2 network cards since it hosts only some backups and the replica of our production network, but if possible, it would be nice...

  I don't know if you still need to have a management network separated with esxi or not, because this is no longer a service console and is a vmkernel interface...

  We currently have with esx

  2 network cards for the network of the virtual machine and management

  1 card network for vmotion

  1 NIC for iscsi

  Don't know if I should just emulate that or not...?  Can I put vmotion and iscsi on the same group of network cards and have each other the failover to the other NIC...?

  Any help would be great!  Thank you...

  Yes, that's all.  You assign an IP address to each VMkernel port.  When you do so, ignore the default gateway field.  You can have a gateway and it will show the gateway you have chosen on the management port.

• iSCSI networks

  I think I have what should be a relatively easy question to answer, im just a little confused right now:

  I created vSwitch1

  I created a group attached to port vmkernal vSwitch1

  I assigned an IP address

  the default gateway has been the default installation of the gateway of the network management

  I have configured VLAN 99 which is my VLAN ISCSI

  When I configure my switch for VLAN 99 ports I can not ping to the IP address of the vmkernel port

  If I change the swtich to the trunk w ports ports / VLAN 99 as well as the management VLAN then I can ping

  What is well configured?  the default gateway must be changed to the default ISCSI VLAN gateway?

  Thanks in advance for any idea!

  Cheers.

  Hello

  If you configure the switch trunk ports and configuring the VMkernel the right port VLAN, you shouldn't have any problem to communicate through this VLAN.

  If you configure the ports on the switch in the access mode, you must configure the VMkernel port without any VLAN in order to communicate through this VLAN.

  ISCSI VLANS must be an isolated network, the gateway is not important when you configure the iSCSI network.

  In any case, check out this link on the VLAN on VMware:

• R900 network configuration

  I have installed new R900 and it has 12 physical network interface cards, but I think I use 2 of them for vSwitch and will run more than 30 virtual machines... One is for SC and one for VMotion. What is the best practice to configure a network on that? any ideas would be appreciated. Thank you.

  We use Dell R905 hosts as well and for configurations you have too many options for all types of traffic.  Set of rules is always use 2 natachasery to a group of unique ports of dismissal and you can figure out from there.  Each groups of ports would be on its own VIRTUAL local network and ensure as much as possible and heres' the suggestion:

  1 vNIC1 - > SC/VMotion

  2 vNIC2 - > VMotion/SC

  3-vNIC3-4-> virtual Network01 machine

  4 vNIC5-6-> DMZ Network01

  5 vNIC7-8-> NFS Network01

  6 vNIC9-10-> iSCSI network

  7 vNIC11-12-> Backup/Out of band/Spare networks

  You can replace these networks as NFS/iSCSI for for various networks virtual machine port groups, if you wish.  But here is the full list of networks, you may have.

  If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!

• How to segragate VM of each other AND Management & iSCSI network traffic?

  I want to test how I can keep VM isolated from each other AND the segments of iSCSI network and management... It's just a proof of concept, so I not be using redundant paths.  I want to know how I can keep all my shelter of the attackers 'would '?  that is if one of the virtual machines becomes "compromise" How could I isolate all "would be attackers" to travel to other virtual machines or networks of management/iSCSI?   Is there a way to create each virtual machine in a VIRTUAL LAN on the ESX host? Or is there a better way?

  For the installation of the physical hardware - sounds?

  TahoeTech wrote:

  "So, to make sure that I understand...". I'll install VMware ESX on

  the physical host machine and then create 3 vSwitches which will be

  related to 1 physical NETWORK card by vSwitch? "

  Since I only need to the DMZ network available to VMS - must - I still 3 vSwitches?

  Yes, one for virtual machines, one for management and one for iSCSI. You may combine up to vSwitches (2) combining management and iSCSI, but it is not recommended.

  The host machine does the iSCSI storage to virtual machines as a "disk"?

  More or less, Yes. When you create a virtual machine, you need to configure the disks for this virtual machine. You will be asked which data source to use, and you choose the iSCSI data store, that you create when you set up the data store and iSCSI.

  The host uses the vSwitches? I thought that the host machine could use physical NETWORK cards... i.e. Teddy 1 would be management and Teddy 2 would be iSCSI, Teddy 3 would be linked to a vSWITCH for virtual machines?

  Yes the host use the vSwitch, after all the console, etc. is a virtual machine its self

  Virtual machines will never see a teddy bear. You want to assign a vNIC to the virtual machine when you create the virtual machine. The vNIC is connected to a group of ports, which in turn is connected to a vSwitch, which in turn is connected to a teddy bear.

  The virtual machines do NOT need access to the networks of management or iSCSI (I don't think)?

  Fix.

  The management network connects to ESX physical HOST (Teddy 1) in order to control the accurate virtual machines?

  The management of the network give you access to control everything via vCenter or the VI client or the command line.

  And the iSCSI network connects to the physical ESX HOST (Teddy 2) where the ESX host will present data warehouses to virtual machines as 'physical' disks correct?

  Yes, it will look like just a physical disk to the VM operating system.

  I guess what I'm trying to understand, or how I see it is that the host ESX is the only machine that has 'see' the iSCSI network?

  The VMKernel manages iSCSI seamlessly. Guests don't need to know anything iSCSI.

  Virtual machines see drives that presents the ESX host? For the virtual machines do not need is access to the iSCSI network (unless I need to install additional storage or drive shared etc...)

  Fix.

  any idea when VI4 is scheduled to be released?

  Rumor is soon. But unless there is there a feature that radically changes your design I wouldn't get too worried about it.

• HP Envy 5540: Printer Hp Envy 5540 randomly printed the Network Configuration Page

  Hello!

  I bought this printer about a month ago. Set up the connection to the printer wireless with my wifi, and my understanding is that the printer is protected like my wifi and use the same password in order to print something. I kept my printer connected and 'standby mode' since I put in place. The night last at about 23:00 when I was in bed, the printer turned on randomly and printed a "wireless network configuration page" that has had a lot of information, including the IP address and listing my name wifi as well as the names of my neighbors wifi in the surrounding apartments.

  I'm trying to understand why this printed, because I certainly did not do. Anyone have access to my wifi, or has someone may simply try to print something and selected my printer as it should appear on the "list available connections on the computer of anyone, given that the printer is turned on? How could they print this sheet of network configuration if my printer is password protected?

  I'm mostly concerned about someone who has access to my internet if they could print this page somehow, but maybe it happened just when they tried to connect to it, and it did not work while trying to fix MY printer?

  I would appreciate any idea on the issue.

  Thank you!

  Hi @printerprob5540,

  Welcome to the HP Forums!

  I saw your post on how your HP Envy 5540 randomly print a Network Configuration Page. I'm happy to help with this problem!

  I find it very strange considering the only way to print the Network Configuration Page, AFAIK, is with the following steps:

  • Make sure that there are size A4 or US Letter, unused, plain paper in the feeder.
  • On the printer Panel, drag the screen to the left and then press Setup.
  • Touch tools.
  • Drag upward on the screen and then tap Network Configuration report.
  • A Network Configuration Page prints up to three pages of information.

  original title: grafting the internet

  Hi Maureen,

  That your router has security enabled protection?  My guess is it doesn't and it's the way that person uses your wireless connection (like someone to visit with a laptop you could if you configure).

  As a general rule, access to the router is by typing http://192.168.1.1 (or whatever your gateway address) in the address bar of your browser and you will be able to bring up the router configuration settings.  He'll probably want a username and password.  Sorry, I can't help you there because I have no idea what it could be.  Try admin/admin or admin/password or administrator/administrator or administrator/password or admin and no password or admin and no password (the classic default settings).  Your ISP or service of technical assistance of the manufacturer of the router may be able to help put this in place.  After that, how configure security entirely depends on the ISP, the router, the type of operating system you have, the type of internet connection you have and a number of other factors that I have no way to know, even if you told me that information.

  In fact, to see if this applies even, go to the Network Center and sharing, and click on manage wireless connections.  Select and double click on your network.  Click the Security tab and see if it is configured with the entries in the drop boxes first two points in the key with a password applies.  If it does not exist, then there is no security on your wireless router.  If there is, then your network is secure without doubt.

  When you see the active connection, click on start / all programs / accessories / and double click on Control Panel.  Type IPCONFIG/all and see if you can identify this other connection of the computer.  It should provide more information about it for the purpose of identification.

  If your router is not secure, you must fix and this should solve the problem.  If your router is secure, you should change the password/key of the router to see if that solves the problem (and then you will need to change the key to all your wireless computers and devices to match the new).  If it still does not work, then come back and we will come with some other ideas (assuming that the manufacturer of access provider or router cannot help you with this).

  I hope this helps.

  Good luck!
