• iSCSI - two subnets on a vswitch iscsi ports link

  Hello

  Is less than supported scenario about binding ports for the software iSCSI (ESXi 6.x)?

  

  Two in two different subnets (2 controllers) iSCSI storage devices: 192.168.10.x and 192.168.20.x (mask 255.255.255.0).

  ESXi host with a vSwitch iSCSI.

  Four exchanges vmkernel: two 192.168.10.x and two subnet 192.168.20.x subnet.

  There is a connection of software ISCSI ports configured for each vmkernel port.

  It is worth noting that this scenario is little different from the examples on VMware KB: considerations for use port binding software iSCSI in ESX/ESXi

  Does not this way. iSCSI ports link requires a one-to-one relationship between the vmkernel ports and vmnic.

  Of https://kb.vmware.com/kb/2045040

  To implement a group policy that is compatible with the binding of iSCSI ports, you need 2 or more ports vmkernel vSwitch and an equivalent of physical cards amount to bind them to....

• Questions about iSCSI and subnets

  IM planning on a deployment of 8 ESX servers connected to an array of iSCSI on double dedicated switches.

  1. 2 cards on each ESX host network is dedicated to iSCSI and VMware dependent ontraffic.
  2. SAN iSCSI target consists of two controllers with 2 uplinks of iscsi on each controller (4 total)
  3. The manufacturer of SAN is suggesting setting up of their SAN ports in separate subnets for higher throughput
  • For the sake of simplicity lets say assign 10.10.100.1 24 ports SAN 1 & 3 and 10.10.200.1 24-port SAN 2 & 4
  • On the side of ESX, a single iSCSI VMKernel address will be 10.10.100.2 and the other will be 10.10.200.2.

  My questions:

  1. do I have to enable trunking VLAN on the side of the switch so that the initiator 10.10.100.2 ESX failover to the port of SAN 10.10.200.1 and vice versa, because they are not in the same subnet and therefore not in the same VLAN?
  2. If this is the case, will trunking VLAN also solve the problem if we were to buy an identical iSCSI SAN on the road and 2 subnets more setup for controllers, but still only have two cards on the ESX Server.
  3. I would assign the 2nd ESX Server in this config with the same IP addresses as the first, or I re them with differnet IPs (but obviously still in the same subnet as the storage arrays), for example ESX 1 is 10.10.100.2 and ESX 2 would be 10.10.100.3

  Any other associated iSCSI I get with VMware, simply not able to think through this particular obsticle and I don't have the equipment to test it yet. Doesn't help that it's late in my part of the world and my brain power is depleting fast!

  Thank you!

  I mean really isolated network. No routing between them.

  Is the software of multiple paths that can pass a path to another, and if you need one network to another.

  Note that the PowerVault will have an interface of a mosquito net and to one another for each processor.

• NFS/iSCSI ports vmkernel - different VLAN?

  I have a question, if you already have a vmkernel port defined for NFS (in vlanX), and if you want to set the iSCSI on the same physical network adapter vmkernel port/ports, then you would give this NIC iSCSI even vlan like NFS or vlanY for iSCSI?

  If you have found this device or any other answer useful please consider useful or correct buttons using attribute points

  I would create different VGA (and VLAN) for the types of traffic.  It's simple, and it will stand the test of time and changes in your iSCSI environment.  You can add network cards later, you can separate the iSCSI network in main switch.

  My situation is a little different to yours I have NFS coming through vPC on Nexus s 2148 (here 1000V) and traffic iSCSI in France via 3750 s (here 1000V).  The NFS traffic using vPC and iSCSI traffic uses MAC pinning and iSCSI MPIO.  Very different profiles.  A time ago I would have found myself in a situation similar to yours, and I took a simple approach to share the same VLAN I would be regret and detangle it right about now

• Satellite Pro M70: Question on the port on the left hand side

  Another question regarding the Pro M70 PSM75E, next to the hard drive (left side) there is a port which you can take off. I took it of and it looks like a chip grafx or something: s someone with the M70 not what it is.

  Thanks again

  Hello

  Well, there are of many Satellite Pro M70. It s a great series.
  But for example Satellite Pro M70-110 has a PCMCIA Type II slot.
  You can use the different PCMICA card in this slot. But they must be compatible.
  I guess this slot machine, you found a plastic Board. This is only for security.

  However, if you want to learn more about your device, I would recommend reading the user manual which must be preinstalled on your laptop. You will find very, very, very ;) useful information.

• Portege 3440CT: Question about media port replicator

  Hi, sorry for my English...

  I have a question:
  I'm looking for a multimedia for my laptop port replicator.

  Do not include the port replicator (PA3042E-1DST) I found a driver for cd/dvd...

  Can I install a standard cd or dvd slim in the multimedia duplicator?
  Or he needs a car?

  Thank you.

  Hello

  I think that you need this one: PA3042E-1DST Multi Media Replicator Port, but according to certain specifications, this port replicator can be used with different options. This means that you must PA3014E - 1DVD DVD Drive Kit or PA3015U-1CDD 24 x CD-ROM Drive Kit II.

  That s all I found.

• Satellite P850 - question about infrared port

  Hello

  I have Windows 8 Pro installed on my laptop and I downloaded all the drivers and everything works well outside the infrared. I've looked everywhere on the internet and I can't find a remote to use with this laptop (especially on the Toshiba site).

  I installed the latest ENE CIR driver (v4.1) as well as the Manager of Toshiba remote (v3.1.0.1). I looked in Program Files to open the command handler Toshiba remote but when I click on the program to open... Nothing happens (including in the notification area).

  So my question is can I actually get a working remotely with this laptop at all, and if not then, what is this infrared port for because I don't find anything on my computer to actually use with/for?

  Thanks for your help: p

  Hello

  Some Satellite P850 models are equipped with the control distance and its possible to use the remote control with Windows Media Center to play discs or videos, see photos and watch recorded TV shows.

  Models who don t understand the a remote controller are * NOT * equipped with an infrared receiver for laptop cannot operate with a remote control.
  The remote was not part of the package for your portable computer does not support the infrared receiver and the Toshiba Remote Control Manager and ENE CIR driver installation was therefore unnecessary

• Question of COM port

  I don't know if it's a question of LabVIEW, or just a more general question, but in any case I'm stuck!

  A piece of equipment that we have just received the laboratory is a Geokon LC - 2 x 16 data logger , which is used to read in 16 (vibrating wire type) meters of the strain.

  Unfortunately, data acquisition comes with its own proprietary software, I still love to avoid if possible.

  The reason is that I have a lot of different pieces of instrumentation and I wish I had all the coordinates in LabVIEW for various reasons, but basically I just have more control and customization in this way.

  In all cases, Geokon software must be running in order to execute the Datalogger (caused by excitation of the strain gauges, communication, etc.).

  This software communicates with the data acquisition via a COM port.

  My hope was that I could just use LabVIEW to listen for traffic on that port and I was able to analyze the data as it came out of a "backdoor" to this type of solution. Once I have given, I can do what I need to do in LabVIEW and avoid other software entirely.

  Here's the problem though: If the software Geokon is connected to this specific COM port (i.e. COM 3), no other software can connect to this port simultaneously. I tried with LabVIEW and same Hyperterminal, or to not seem to work.

  Someone at - it an idea on how I could go about this?

  Cory,

  The manual for this contains all ASCII commands for configuration/control instrument.  Should you need to create your own LV driver.

• Another question on serial port communication

  Hi all!

  I started working with tools of communication series LV (actually, I'm a newbie in LV at all).

  The question is - how I effectively detect y at - he new data arrived in the read buffer VISA?

  I mean, in the examples I found, there is always a fixed delay between writing series and the read operation - it makes the instrument depends on the speed of communication and (worse) on the response time of the required device. I want to implement is a vi that writes a (or different applications) via a serial port and then check periodically (with the relatively small period, say, 1ms) series read buffer for the response data until new data stops arriving. For this I need to know the number of bytes of data into the buffer, or a property (if any) detecting the arrival of new data.

  As I read on this forum (and figured out from my own experience)-using VISA bytes to the Serial Port is ' t a good idea also I have found a solution without delay set by the user between the writing and the read operation in the recent previous topics.

  Can you give me an opinion?

  Thnx in advance.

  Use VISARead with a number of bytes to read and a timeout.

  When your data is received it will play instantly. When no data comes in, you will get a time-out error, which you can manage!

• Basic questions about the port of Vsphere mirror

  I set up a lightweight VM that would deal with inter-VM traffic. To do this, I want to activate the duplication of port between virtual machines.

  
  

  I have ESXi 5.5 Update 1 installed, use the Vsphere (no webclient) client. I see no duplication of port capacity on my Vsphere Client

  

  I have some very basic questions:

  (1) all documentation I've read involving 'Port mirror' is done via web Vsphere client. Vsphere is provided with Vcenter (please, correct me if I'm wrong)

  (2) only functions with "Distributed Virtual Switch", not "switch vSphere Standard" port mirroring. How can I activate "Distributed Virtual Switch"? What products can I download/install and try (suppose I go to the user a license for 60 days)

  (3) exist what API to enable/disable/setup Port mirroring?

  (1) all documentation I've read involving 'Port mirror' is done via web Vsphere client. Vsphere is provided with Vcenter (please, correct me if I'm wrong)

  Because the mirror of port requires a distributed switch, you will need to vCenter Server and once in vCenter Server, you can the vSphere Web Client of the user or the vSphere Client (c# version).

  (2) only functions with "Distributed Virtual Switch", not "switch vSphere Standard" port mirroring. How can I activate "Distributed Virtual Switch"? What products can I download/install and try (suppose I go to the user a license for 60 days)

  You can download the server vCenter Server (60 day trial) and you'll have an Enterprise Plus version for your ESXi host vSphere.

  (3) exist what API to enable/disable/setup Port mirroring?

• ESXi 5.1 Lab question (resolution/iSCSI discovery)

  I have setup a physical environment 2 node ESXi works as expected.

  iSCSI, WDS/PXE, DHCP, DNS, LDAP are all setup and running on a Windows Server, vCenter (VM) is configured and works perfectly.

  Looking to set up RS using VR through 2 virtual data centers I raised 4 VM I deployed ESXi 5.1 using the WDS/PXE of R2 2013 server and everything worked perfectly (wise deployment).

  The use of Kickstart scripts ESXi hosts are fully deployed to VM with 1 GB of storage (sufficient), IP stack, host name, etc. everything is correct.

  First number using the "Test management network' fails resolve host names of all 4 systems (Pings from the work of gateway and dns addresses.). But if I ssh in the hosts and the use of nslookup I can solve all well? Whats up with that?

  
  

  Second question which I think is related, is that I am setting up an iSCSI S/W to each adapter and you have configured ldevs/LUN with chap authentication identically as I did for the physical data center and I can't auto-discovery or entries static to discover the storage provisioned. the IQN name have the hostname in them which I believe is originally a resolution problem. For the Autodiscover I use the IP address of the iSCSI server so there is on the resolution of current names.

  All them is on a subnet (255.255.255.0) single 10.10.10.x/24.

  Anyone who can get an idea of why this is happening I would appreciate the help!

  Found the problem...

  Have a Gateway Appliance ClearOS which has several interfaces causing a loop.

  It cleared up and removed the questions.

• Question of vCO Port connecting to vCenter

  Hi all

  I have a problem that I hope can be easily solved. I'm pretty sure I know what the question is, just not how to correct it. When I created vCO to connect to vCenter I get the error "Exception," org.apache.http.conn.HttpHostConnectException: connection to http://vcenter.domain.com:80 denied ' "» What I know about the environment, vCenter here is actually using port 8080 for http connections. I can't change this behavior in vCO so far. Here are two screenshots for configuration and the error itself:

  

  

  No way to change the port vCO tries to use on the side of http, or just something that I'm missing (seems likely )?

  Thank you!

  jaytindel,

  Apparently I completely missed this all the time, while I was completely up to date with the generation which implement a 'solution' to this question, there is always a workaround solution that must be followed. A VMware support engineer guided me to a KB and using the solution of creating a workflow to add the vCenter Server works in fact for me. This is the KB:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=2042461

  Let me know if you encounter any problems with it.

• question of iSCSI with D-Link DSN-2100-10

  Server: HP DL380 G7 equipped of 4 ports (BCM5709) Broadcom adapter

  SAN: D-Link DSN-2100-10 (the latest firmware upgrade)

  Hypervisor: ESXi 5.0 U1 (build 623860)

  I have a few problems with access to the San, just using one of the four adapters to Broadcom iSCSI detected by ESXi, after implementation of the VMkernel port binding, I have run the dynamic discovery and after waiting for 10 minutes, the target is detected but is not accessible by train. At this point, the host became unstable do not allow me to access, ping to the host is expired. After a few minutes, the host is still once I could only have access via SSH and not through vSphere and after restarting the server via SSH, the host is accessed again by vSphere but the target iSCSI not still not accessible, and if I try to make simple as rescanning for HBA operations or remove the target dynamic discovery or static tab the to host crashes again with the same strange behavior.

  If I install and configure VMware iSCSI Software adapter, the target is almost instantly and without performance problem. I also configured 2 Ports of iSCSI binded to 2 network cards on a single vSwitch for multichannel goal and it's working like a charm, but I suppose for the moment that I can't benefit from the unloading feature of my NIC iSCSI. The only problem with this configuration is a few warnings San logs on which I look at (invalid field in the message of the CBD when I perform an action on the data store)

  Any suggestions?

  In my view, the storage is not supported by the VMware HCL, is it not?

  Sorry for my response, but it is a problem that I have in fact! Storage is supported up to ESXi 4.1U2, but I want to upgrade to ESXI 5 hypersivor...

  Maybe you have any other suggestions or solutions, to help me solve the problem? I will ask support from DLink and VMware for a solution too.

• question of iSCSI san

  Hello everyone,

  I just created my first with software e open iscsi san solution.

  My situation: on the local disk, I put my VM

  I created 4 iscsi data warehouses

  1 will be used to back up my VM and can be reached for Vsphere

  The other 3 serve as a backup for my 3 VMS solution. I am connected to them through the Iscsi initiator in the virtual machine, format them, and now they appear as an additional drive in the virtual machine. I can see them in Vsphere but is no longer in data warehouses, but in devices (because they are formatted as NTFS)

  Now the question:

  Is it possible to see what data is on data warehouses that are formatted to ntfs When you are not connected to the virtual computer?

  When a virtual machine should crash, backupped data should always be saved to disk iscsi, but where can I get it?

  Thanks in advance, onkt

  NTFS is only accessible via windows server only. You can mount the iSCSI drive backup on another virtual computer.
