iSCSI network problem

• 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.

• 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:

• Vista unidentified network problem

  My HP G60 laptop under vista home premium got an "unidentified network" problem and not able to get on the internet. I even tried to reinstall vista to factory default, still the same problem with my wireless router.

  Spec:

  -HP G60 laptop computer, running vista Home premium 32-bit, with 3 GB of RAM

  -Belkin router

  -I am able to connect via a fine wired line but with a Wi - Fi, it shows constantly 'unidentified network', even if I changed the Private mode in network and sharing Center.

  -J' tried the following: listed an SSID different router, reset the router by default, to reinstall vista, tried other mechanisms, such as specified in the forum, with no difference

  -When you configure the router, I have clone MAC of the laptop to the router to get the connection with Comcast, has done that with network cable connected, internet connection worked well after cloning.

  -no virus SW installed.

  Any suggestions on what might be the solution here? Thank you.

  Hello

  It seems that something is blocking the wireless to connect to the wireless router and to obtain a valid IP address.

  Maybe this can help.

  These steps and tell us where is the breaking point.

  Check the Device Manager for the wireless card valid entry.

  http://www.ezlan.NET/Win7/net_dm.jpg

  If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

  Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

  http://www.ezlan.NET/Win7/net_connection_tcp.jpg

  ------------------

  The wireless card drivers much also install utility wireless of the seller.

  Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

  ----------------

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

  If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

  party like Hello and NetMagic 3rd network managers can block local traffic too.

  ---------------------------

  Stack TCP/IP work should look like.

  Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

  http://www.ezlan.NET/Win7/status-NIC.jpg

  Description is the data of the card making.

  The physical address is MAC of the card number.

  The xx must be a number between 0 and 255 (all xx even number).

  YY should be between 0 and 255

  ZZ should be between 0 and 255 (zz all the same number.)

  The date of the lease must be valid at the present time.

  * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

  * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

  ---------------------------------------------------

  A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

  Above everything is OK, you must be able to connect to the router.

  Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

  If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

  Enable security wireless after you eat to make a functional connection.

• 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

• PE2950 intermittent network problems

  Hey guys, I have a PE2950 running Windows 2008 R2. It's a (non-primary) domain controller and I'm having all sorts of problems with replication errors. I also have problems with DNS errors.

  When I log on the 2950 and run nslookup ifc.local, sometimes it comes complete with success immediately. Then if I run it again a few seconds later, it expires. I checked the reverse on both servers search areas and have the correct PTR records (it seems) and points NIC of each server to the other server, and then to his self for DNS. There are forwarders in DNS records, but not on the network card. I seem to have no problem with the PDC network (a 1950).

  It seems that my network problem is intermittent and can be hardware/driver related, but I'm not sure. One thing I found interesting is that if I try to activate IPV6 on the 2950's NIC, I receive an error message that says I need to install a network card in order to configure TCP/IP, but there is clearly a here and IP4 is set up very well.

  IPconfig shows also two cards tunnel I'm not familiar with. Clear that they are not used. I would like to disable some how?

  Here are the results of an ipconfig/all and nslookup example. Of course, when I went to this post, I couldn't nslookup to expire, but when he does I have server: UNKNOWN and IP address correct and therefore three lines of time-out.

  Thanks in advance for any help you can offer!
