  findiSCSIDevice action () returns the string iSCSI device, and not as an object.

  You can duplicate this action (say under a name findiSCSIName) and change its script code by replacing the following line:

  return busAdapter.device;
  

  with

  return busAdapter.iScsiName;
  

  and then use it in your workflow and actions of something like

  var hbaScsiName = System.getModule("com.vmware.library.vc.storage").findiSCSIName(host);
  

• How to configure rdm to use iscsi lun in a virtual machine using ms iscsi initiator?

  I have equallogic SAN attached to a cisco 3750

  switch. It comes to our storage network.

  Within the virtual machine for all readers of data other than my c:\ that has the operating system I would use iscsi data switch that has 4 network ports on four different nic cards already assigned.

  According to what I read a virtual machine can use only 4 nic so I have a Production network the other three that I would

  Use it for iSCSI data.

  Three ports of each virtual computer network for using ms iscsi with MPIO

  initiator.

  I have already attached the RDM using esxi 3.5 as a physical mapping of RDM.

  My question is how to configure the ports of the network adapter in the virtual machine?

  The VM network is on 172.19.2. * where iscsi is on 172.19.21. *.

  What would be the entrance on the network adapters in the virtual machine that is running ms win 2 k 3 r2 x 64.

• How to boost the performance of iSCSI SAN

  People,

  I'm testing below the solution with provided hardware / software Details and I don't get maximum output according to what I'm supposed to get.

  I tried everything and read all the manuals and the recommendation that offers VMware but still no lock...

  Multipathing helped and I was able to acquire 150 MB for all, but a single virtual machine acquires a fraction of it. I tried up to 4 paths, and there was no additional benefit beyond 2!

  Any suggestions would be very boiled so highly appreciated.

  Hello

  Get a throughput with iperf does not mean that your network is not a bottleneck.

  For example, flow control can have a huge improvement on throughput of SAN, without touching all-time iperf.

  There is not much to go wrong with VMkernel that slow iSCSI, unless you go to paths multiple questions.

  Specific parameters of Multipathing can have a significant impact on the flow - I would like to ask what a summer your recommended ATAS and PSP and if RR IOPS are relevant, but which amounts to determine if your San is actually a taken SAN supported.

• How to change the name of a volume iSCSI target?

  How the name of a volume iSCSI target can be changed?  I created a volume with a typo in a letter.   The volume production data on it now so I can not just it delete and recreate the problem.   It's not a big deal, but it doesn't look good either.

  It's on a PS6100.   When I go into the properties of the Volume in the advance tab I can see the iSCSI name, but cannot change it.  All I change is the public alias.  But it does no good that the name appears in the vCenter with the misspelled name.

  So how can I change the iSCSI name?

  Or am I stuck creating a new volume and telling them to migrate their data for spelling can be fixed?

  See you soon

  Part of the iSCSI specification is that target names must be unique.  Therefore, once created, you cannot change the name of the volume.

  Kind regards

• With the help of site with iscsi

  You will need to validate whether you site for a config where vmotion and iscsi share the same vmnic.

  MY idea is to set up a single vDS with 2 vmk for iscsi connections, 1 with vmnic2 active and vmnic3 not used, the other vmk would be configured inversely with active vmnic3 and vmnic2 as unused.

  Now now for vmotion I would create a configuration multi-NIC where vmnic2 is active and vmnic 3 is not used and once again the 2nd vmk vmotion would be configured conversely where vmnic3 is active and vmnic2 is not used.

  VMotion networks would be configured w lower priority than iscsi networks to allow storage traffic

  Concerns:

  in iscsi multi pathing others vmnic in the vDS other than the active vmnic must be unused when the use binding, it is also the case for several microphones vmotion or is having other vmnic in the ok mode standby?  Which is the preferred method?

  the above configuration is officially suppotted?

  site slow performance of iscsi network will somehow?

  Thanks in advance

  Unlike iSCSI use cases for Multi-NIC vMotion inactive NICS must be configured as standby and not as unused.

  See VMware KB: Multiple-NIC in vSphere vMotion 5

  the above configuration is officially suppotted?

  Yes.

  site slow performance of iscsi network will somehow?

  It obviously depends on how to actually configure NIOC and how the consumption of bandwidth real iSCSI and available bandwidth. Usually you would not define the limits of the NIOC on iSCSI traffic bandwidth and assign a higher priority as well.

  You can also consider to use the traffic on the port vMotion group shaping, see the following articles:

  Test vSphere NIOC host limits on Multi-NIC vMotion traffic | Network of Wahl

• iSCSI target shows no not in devices

  Hi all! Very new user here...

  I started having a few storage errors when implementing new virtual machines, so it's time to add on. I have a few Sataboys Nexsan around my laboratory and easily hung them in the past. I created a vswitch just for iSCSI:

  

  Then, I went to the adapters initiator software and storage enabled, the value of the vswitch3 (vmk1) network, dynamically discovered my storage and then the name of the target appeared in the static method. I then reread and nothing shows up under devices.

  

  So I looked in the CLI and here's some additional info (not sure how useful but good, I learned how to do it):

  Can someone provide clarification on what I'm missing here?

  Make sure that your network is perfectly done. If so there is nothing to do more esxi end, your institution seems correct to the screensshots that you have shared. Now this topic is the part of storage that can be verified for.

• the iSCSI LUN mapping

  How ESXi is mapped LUN vmfs iSCSI extends? The reason why I ask, is that in my opinion, he should do a mapping to make it persistent after a reboot?

  fajarpri wrote:

  @Rikard, similar like that. How ESX knows that Lun0 will extent1 and Lun1 goes to extend2 in this store a data?

  Wouldn't there is possibility that ESX detects Lun1 first than Lun0 and thus risk recognizing as extent1?

  I guess it's a bit 'Internal ESXi', but it should be the NAA or T10 number reported by the SAN and no id LUN itself using ESXi to recognize discs. Given that these numbers never change, there is risk of errors between reboots. I have a vague memory of which is a kind of question on the 3.x versions, but do not these days.

• ProLiant BL460c G7 iSCSI SAN boot

  Hello
  I'm looking to start a single ProLiant BL460c G7 of our HDS iSCSI SAN and then install ESXi 5. The blade has no local storage. The SAN is already in use by the cluster of our production.  In the iSCSI SAN config guide it States to set up storage so your host has access LUNS. How can you do this if your host is not installed? How can I configure the LUN to only be accesed by my hosts IQN name when I don't have an IQN name yet? What I must first install ESXi? I'm obviously missing something any help would be great!

  This is true, for this, but as your correctly point out if the OS is not installed how do you have a software iSCSI initiator - boot from an iSCSI SAN is supported only if you have an initiator of independent hardware installed in your ESXi host.

• Adding another target iscsi

  Hello

  One of our hosts running 3.01, currently on an iSCSi SAN Netapp. We have deployed just a Compellent SAN, how do I add a new ISCSi target? In the dynamic discovery tab of the initiator, I added the server (and port 3260), but also add known as iqn on the general tab? The reason why I ask this before I try it is I don't ' want to lose the connection in progress, and I'm afraid to hit set up under the general tab and entering the new iqn name could remove it.

  Thanks in advance,

  After the target storage has been added via Discovery dynamic all LUNS presented to the esx host must be visible in the sight of devices for the software iscsi adapter. He will go through the process of a new analysis of the storage adapter to recognize the new storage and should not cause problems with the currently connected storage.

• OK, why ISCSI

  Can someone tell me why one of my servers will see an ISCSI target and the other will not be when configured in the same way? ISCSI stores my VM

  Would be really helpful to know are the SEM, how they are configured (with the help of CHAP or not?), but also how the networks are configured for iSCSI on both hosts... Do you use dynamic or static iSCSI target discovery?

• Need help to set up my dish-solution ISCSI network

  If the network is flat and since then have been introducing iscsi I want to segment the iscsi traffic, but networking's obviously not my thing.

  How would I go about isolating iscsi traffic? We are a Microsoft shop. Microsoft DNS and 10. .. * network.

  A bit of a personal choice.  But we put our iSCSI on two netowork unmanaged switched networks completely isolated from his own.    Decent switches non-managed CONCERT are darn cheap these days.

• Requirement of startup SAN

  Hello community members!

  It's my first article (question).

  Very grateful for any help.

  I intend to install about 10 ESXi hosts with the boot from SAN (EMC storage).

  Honestly, I have never deployed before SAN boot.

  Are there best practices for SAN boot? Should I ask one number of logic unit for all the ESXi host operating system? or should I ask 10 LUNS 10 ESXi hosts?

  What will be the size of the LUN that is recommended for the host ESXi (1 or 10 OS) operating system

  Should I ask a separate logical unit number for ESXi OS?

  Thank you

  Using iSCSI or FC?

  You can read the Documentation for vSphere on boot ESXi of FC SAN, iSCSI or FCoE:

  Documentation Centre of vSphere 5.5 - boot ESXi SAN Fiber Channel

  VSphere 5.5 - boot ESXi with FCoE Software Documentation Centre

  5.5 vSphere Documentation Centre - using ESXi with iSCSI SAN

  Make sure that your cards HBA/iSCSI and tables/storage support boot from SAN/iSCSI

  Yes, you will have to ask that a LUN separated for your ESXi 10 hosts means LUN 10 (some provider requires LUN ID 0).

  Don't forget to hide only the start host LUN, boot boot from SAN LUN must be masked exclusively to their host.

  The host can obtain the wrong identity an incorrect LUN then you configure single initiator zoning in trunk of SAN.

  The Emulex, QLogic BIOS can become insensitive, if several other initiators are in the same area and you try to select a LUN to start.

  For the requirements of LUNS, you can prepare LUN ~ 6 GB for each such logic unit number as described in the Documentation Centre of vSphere 5.5 - Configuration hardware ESXi

  Storage for a 5.5 ESXi Installation requirements

  Installing ESXi 5.5 requires a boot device is a minimum of 1 GB in size.

  When booting from a local disk or SAN/LUN iSCSI, a 5.2 GB drive is necessary to allow for the creation of the VMFS volume and a scratch 4 GB partition on the boot device.

  Some associated KB as below:

  VMware KB: Preliminary Configuration for Boot-from-SAN

  VMware KB: Recommended disk or size LUN for VMware ESX 3.x / 4.x and ESXi 3.x / 4.x / 5.x installations
