• Is iSCSI boot supported with VMware 5.5?

  Hello

  I see that VMware 5.5 is supported with the latest UCS code.  Do you know if it supports the iSCSI boot?

  Thank you.

  Hi Carl,

  Yes, it is, you can also check by looking at the compatibility below matrix (see example).  I would like to know if you have any questions or accept this post if I answered your questions

• ISCSI Boot B200 M2 need, but get 'not enough available vNIC.

  Hello

  I'm trying to implement initialization iSCSI ESXi on a B200 M2 w / M71KR-Q card above.

  I add vNIC A and B (each linked to a fabric respectively), but trying to implement a vNIC iSCSI - I get the error «not enough vNIC» available

  Looking around, it seems that M71KR-Q only can support 2 vNIC (which I also confirmed by trying to add a third, same error message as above).

  I just thought that since the overlay of iSCSI vNIC real - it works.

  However, even when adding just 1 vNIC and trying to superimpose a vNIC top iSCSI - I get the "there not enough resources overall, not enough vNIC available" error message.

  Does anyone know if it is even possible to initializing iSCSI on B200-M2 w / M71KR-Q on?

  Thanks in advance!

  Please refer to this document in the section documents iSCSI boot https://supportforums.cisco.com/docs/DOC-18756 it is very detailed, I tell myself.

  initializing iSCSI is only supported on CiscoVIC and Broadcom mezz cards. It is not supported on the M71KR-Q Qlogic Gen - 1 mezz.

• UCS ISCSI Boot Jumb MTU

  Light and matter seeks jumbp MTU working for ISCSI boot.

  UCS 6248S

  IOM 2208

  VIC YEARS 1240

  5.1 ESXi update 1

  VNX 5500

  I have a few rack mount hosts with 10G network cards, who works with jumbo MTU and I can vmkping the VNX SPs with ' vmkping d s 7000 10.1.1.1 "and it works.

  In UCS the operating system starts on the VNX via ISCSI

  The ISCSI network is a pair of Dell Force 10 S4810s

  UCS FI - A and FI - B have 2 10 uplinks in a s port LACP on the strength of Dell 10 channel

  Checked the jumbo MTU is enabled on the side of Dell

  The system class QoS now occupies the 9216

  There is a QoS ESX ISCSI strategy mapped to the class gold

  ESX ISCSI strategy is mapped to 2 vNIC models; one fabric and a fabric b

  If I set the MTU on the vNIC model 9000 errors the OS at startup a message on start-up banks missing

  If I set the MTU on the vNIC model 1500 the host boots fine

  I put groups of ISCSI ports and vSwitch to 9000 in ESX, but I cannot ping the VNX SPs with a package of more than 1500.

  Attached is a diagram

  Someone at - he of the clues as to what I'm missing? Thank you

  Make sure that you assign you best effort to 9216 so class on the system UCS class.

  The return traffic is probably not sent with a COS value so the UCS is the treatment to best effort which by default is 1500.

• iSCSI Boot on IBM Bladecenter

  Hi all

  Were switching environment leaves IBM with 32 GB of RAM and

  built in maps iSCSI. With that, we do iSCSI boot for the

  Drive to ESX. someone at - it experience with this? When I put it initially

  up, I did the installation with just an active card, it went very well, and

  on the prior knowledge of the fiber, I activated then the 2nd card and cela

  has run fine for a few days... Eventually the file system went read only.,.

  and I contacted Netapp. They sent documentation which seemed ot

  say disable the 2nd card, unless you will begin her. In

  addition, I had to completely out of the IP of the 2nd card

  to ensure that the errors do not return.

  Is this normal?

  Have you installed the Netapp iSCSI utility on each ESX Server ESX host? I also believe that I saw a Netapp engineer mention in his blog to turn off the second card at the start of SAN.

• IBM HS22 iscsi boot

  We bladecenter HS22 and tries to boot from iSCSI. Could someone do?

  At first, I don't know if I have it set up correctly, and in the second place, when I start installing esx 4 it cannot detect all partitions.

  The HS22 has a Broadcom NetXtreme 2, someone has set up one of these guys before, and he got to work.

  Second, the ESX 4 install the need of additional drivers during installation to detect partitions mapped to the NIC iscsi?

  Thank you very much.

  http://www.VMware.com/PDF/vSphere4/r40_u1/vsp_40_u1_iscsi_san_cfg.PDF

  Chapter four, begin an iSCSI SAN with ESX systems, which begins on page 51, says "guests only ESX with hardware iSCSI initiators can boot from SAN.

  Check the HCL to the product Versions Release = ESX4 and Type = iSCSI, return 20 results, which are all QLogic 405 x and x 406 re-slotted different forms.

  Probably not clear as you or your boss wants, however.

• ADAM Target Recon questions

  Hello experts,
  
  I need to deploy an ADAM connector in the system.
  Because there is already a connector AD, I have reproduced the AD one and I've implemented it as an ADAM.
  
  I was able to correctly reconcile the search for the Organization, the commissioning went very well, but the Recon target seems sends problems.
  
  According to the documentation of the connector, I traced only required fields of ADAM:
  -J' added in resource objects only the cn, upn, displayName, sn, givenName, accountExpires and the ObjectGuid and I created a profile of reconciliation
  -J' added in the process, the fields of reconciliation, mapping of the CN, upn... to the column of the ADAM object
  -J' have changed the search in relation to the areas of reconciliation, keeping just the previous fields
  -J' added User Login rule == common name (no samaccountname in ADAM)
  but when I run the target user Recon task does not work.
  
  I ran this simple test: I create John Smith in IOM, I have available, I change his first name to Johnny in ADAM and I him reconcile.
  
  Even if from the Console of Admin, I see that the task is completed with a State of success, "The TimeStamp of a/d converters" remains at zero and no event is present in the "reconciliation events.
  In addition, in the trace to the TRACE log: 32, I have the following error, but it didn't help me find a solution.
  A larger extract of the newspaper, I see that it gets properly ADAM user information, and all fields are filled in correctly.
  I have a feeling that this may be because something doesn't work not with the rule, even if it takes the right information to ADAM, he is not able to understand what user IOM assign the ADAM Object.
  
  You have an idea?

• Boot from ISO question

  The host is Windows Server 2 k 8 x 64 SP2 STD.  Guest is Windows Server 2 k 3 STD SP2 (32 bit) running in VMWare Workstation 6.5.2.  I need to fix the 2 k 3 VM, which requires that I have boot from the CD, but I don't have that an ISO, CD. I use Daemon Tools Lite to mount the ISO as a drive, but I don't know where to create the virtual DVD_ROM disc such as the virtual machine can / will see when I boot it (I tried to get on the host and the guest). I already went in the BIOS of the virtual machine and modified so that he will see the DVD - ROM drive until he goes on the hard drive. I tried to share my virual DVD_ROM, but have been unable to map it to VMWAre Workstation. None of these things have solved the problem. How do I (or it is even possible to ~) put things up to the boot prompt of the ISO?

  Navigate to the virtual machine settings.  (VM menu, settings)  Then change the connection to "Use physical drive" CD to "use ISO Image file.

• I share the same target iSCSI with multiple hosts?

  I have an iSCSI LUN target that appears when I discovered the storage for an ESXi host, but when I discovered the storage for another host, it does not appear. I added the suitable adapter software network and iSCSI on the second host, dynamic analysis and he sees the same iSCSI target, however when I go to 'Add a storage' there is no displayed LUN.

  I'm obviously missing something, I just can't understand what it is.

  Any help would be greatly appreciated!

  Storage Area Network - FC and iSCSI - do not automatically appear LUN to all hosts that connect to them. This is also called masking and prevents accidental access to LUNS of the host that is not allowed access to that LUN. You must configure the storage system, access to the LUN - once you do this for the other hosts will be displayed in the list and you will be able to access all hosts logic unit number.

  To avoid trampling of the ESXi put a lock on the VMDK so that a subsequent host will not be able to power of the virtual machine and write than disj virtuak

• Port-groups, vSphere 5 and Jumbo (iSCSI) frames

  We will implement a UCS system with EMC iSCSI storage. Since this is my first time, I'm a little insecure in design, although I have acquired a lot of knowledge to read in this forum and meanders.

  We will use the 1000V.

  1. is it allowed to use only a GROUP of ports uplink with the following exchanges: mgmt, vmotion, iscsi, vm network, external network?

  My confusion here is what jumboframes? Should we not separate for this connection? In this design all executives are using jumboframes (or are this set by portgroup?)

  I read something about the use of the class of frames extended Service. Maybe it's the idea here.

  2. I read in a thread do not include mgmt and VMotion in the 1000V and put it on a vs. Is this correct?

  In this case, the design of uplink would be:

  1: Mgmt + vMotion (2 vNIC, VSS)

  2: iSCSi (2 vNIC, 1000v)

  3 data VM, external traffic (2 vNIC, 1000v)

  All network cards for parameter as active, Virtual port id teaming

  I have 2 follow-up questions:
  1. What is the reason I cannot use a 1000V uplink profile for the vMotion and management? Is it just for simplicity people do it that way? Or can I do it if I want? What do you do?
  [Robert] There is no reason.  Many customers run all their virtual networking on the 1000v.  This way they don't need vmware admins to manage virtual switches - keeps it all in the hands of the networking team where it belongs.  Management Port profiles should be set as "system vlans" to ensure access to manage your hosts is always forwarding.  With the 1000v you can also leverage CBWFQ which can auto-classify traffic types such as "Management", "Vmotion", "1000v Control", "IP Storage" etc.
  2. Shouldn't I use MTU size 9216?
  [Robert] UCS supports up to 9000 then assumed overhead.  Depending on the switch you'll want to set it at either 9000 or 9216 (whichever it supports).
  3. How do I do this step: "
  Ensure the switch north of the UCS Interconnects are marking the iSCSI target return traffic with the same CoS marking as UCS has configured for jumbo MTU.  You can use one of the other available classes on UCS for this - Bronze, Silver, Gold, Platinum."
  Does the Cisco switch also use the same terms "Bronze", Silver", "Gold" or "Platimum" for the classes? Should I configure the trunk with the same CoSes?
  [Robert] The Plat, Gold, Silver, Bronze are user friendly words used in UCS Classes of Service to represent a defineable CoS value between 0 to 7 (where 0 is the lowest value and 6 is  highest value). COS 7 is reserved for internal traffic. COS value "any"  equals to best effort.  Weight values range from 1 to 10. The bandwidth percentage can be  determined by adding the channel weights for all channels then divide  the channel weight you wish to calculate the percentage for by the sum  of all weights.
  Example.  You have UCS and an upstream N5K with your iSCSI target directly connected to an N5K interface. If your vNICs were assigne a QoS policy using "Silver" (which has a default CoS 2 value), then you would want to do the same upstream by a) configuring the N5K system MTU of 9216 and tag all traffic from the iSCSI Array target's interface with a CoS 2.  The specifics for configuring the switch are specific to the model and SW version.  N5K is different than N7K and different than IOS.  Configuring Jumbo frames and CoS marking is pretty well documented all over.
  Once UCS receives the traffic with the appropriate CoS marking it will honor the QoS and dump the traffic back into the Silver queue. This is the "best" way to configure it but I find most people just end up changing the "Best Effort" class to 9000 MTU for simplicity sake - which doesn't require any upstream tinkering with CoS marking.  Just have to enable Jumbo MTU support upstream.
  
  4. Concerning Nk1: Jason Nash has said to include vMotion in the System VLANs. You do not recommend this in previous threads. Why?
  [Robert] You have to understand what a system vlan is first.  I've tirelessly explained this on vaiours posts .  System VLANs allow an interface to always be forwarding.  You can't shut down a system vlan interface.  Also, when a VEM is reboot, a system vlan interface will be FWDing before the VEM attaches to the VSM to securely retrieve it's programming.  Think of the Chicken & Egg scenario.  You have to be able to FWD some traffic in order to reach the VSM in the first place - so we allow a very small subnet of interfaces to FWD before the VSM send the VEM's programming - Management, IP Storage and Control/Packet only.  All other non-system VLANs are rightfully BLKing until the VSM passes the VEM its policy.  This secures interfaces from sending traffic in the event any port profiles or policies have changed since last reboot or module insertion.  Now keeping all this in mind, can you tell me the instance where you've just reboot your ESX and need the VMotion interface fowarding traffic BEFORE communicating with the VSM?  If the VSM was not reachable (or both VSMs down) the VMs virtual interface would not even be able to be created on the receiving VEM.  Any virtual ports moved or created require VSM & VEM communication.  So no, the vMotion interface vlans do NOT need to be set as system VLANs.  There's also a max of 16 port profiles that can have system vlans defined, so why chew up one unnecessarily?
  5. Do I have to set spanning-tree commands and to enable global BPDU Filter/Guard on both the 1000V side and the uplink switch?
  [Robert] The VSM doesn't participate in STP so it will never send BPDU's.  However, since VMs can act like bridges & routers these days, we advise to add two commands to your upstream VEM uplinks - PortFast and BPDUFilter.  PortFast so the interface is FWD faster (since there's no STP on the VSM anyway) and BPDUFilter to ignore any received BPDU's from VMs.  I prefer to ignore them then using BPDU Gaurd - which will shutdown the interface if BPDU's are received.
  Thanks,
  Atle, Norway
  Edit:
  Do you have some recommendations on the weigting of the CoS?
  [Robert] I don't personally.  Others customer can chime in on their suggestions, but each environement is different.  VMotion is very bursty so I wouldn't set that too high.  IP storage is critical so I would bump that up a bit.  The rest is up to you.  See how it works, check your QoS & CoS verification commands to monitor and adjust your settings as required.
  E.g:
  IP storage: 35
  Vmotion: 35
  Vmdata: 30
  and I can then assign management VM-kernels to the Vmdata Cos.

• initializing iSCSI SAN in VMWare Workstation 9

  Hi all!

  I created an iSCSI Target (Debian Wheezy) and an iSCSI Initiator (CentOS 6). Installation of netinstall (of CentOS) on eth0 to LUN0 on eth1 worked very well. Adjusted BIOS on VMWare to boot from first e1000. At startup, the operating system tries immediately PXE boot, iSCSI not...

  Any big brain here know what I'm doing wrong? I got about 16 hours sunk trying to develop this project, so any help would be appreciated! Thanks in advance for your time!

  Here is the answer to my problem: VMWare Workstation 9 does not support iSCSI boot.  It requires 'PXE chainloading', where a gPXE (or iPXE), PXE loads image gives VMWare PXE allows to start an iSCSI target.  Here are some valuable pages, I found on the subject, even if none show my specific "PXE boot CentOS of Debian iSCSI in VMWare Workstation 9"... guess I am the only one to write this tutorial!

• Can I use VM 2nd NIC to access target on the storage network?

  I'm running ESXi 4.1 on an isolated network iSCSI network storage with 1 NIC physical on the management network, 4 physical network connected to the Production network interface cards, and 4 NIC physical and all my VM is Server 2008 x 64. Until the budget will allow, without my actually are Dell PE 2900 of servers running Windows Server 2008r2 and Microsoft iSCSI Software Target 3.3 with various sizes of PowerVault DAS, which is 15 to. Here's my question regarding this configuration. The environment in which I work in requires the use of an application that needs the access card to a server that has more than 10 TB of structured of maps and images. For the sake of future growth, I decided to go the normal way of iSCSI target as opposed to sharing/server configuration, so I created a 14.5 TB iSCSI Target .vhd and all my data have moved to this location. In addition, I have one of my servers iSCSI Initiator pointing to the target VM (exported snapshot)... through my network of production... where it is mounted as a read-only disc, configured as I need to be and spread my desktop map. This configuration works well, but the fact that my VM accesses the target via my production network is certainly not the way I need it to be installed, I really need to access the network storage iSCSI initiator. Confused yet? I really need to keep my out of the Production Network iSCSI traffic, but so far I have not been able to find a method to add a second NETWORK card on my virtual computer and put it on anything other than the VM network. I have no problem at all with my host ESXi accessing iSCSI target data warehouses that I created on my other AD, but obviously, there are enormous obstacles to the creation of a 14.5 TB data store, while a 14.5 to SAN target is very flexible and easy... now how can I shoot by the storage network team.

  I appreciate the answers really, but I'm composing this House as VMWare communities are blocked on my work network. However, given that the responses are also sent to my email... I will receive them as text and therefore all references to added images etc will have to wait until I get to watch. Answers appreciated text.

  Thank you

  Confused yet?

  Yes, absolutely

  I don't know if your configuration iSCSI in detail, please consider my suggestion carefully. Access the iSCSI virtual machine network directly should be as simple as adding a group of ports 'Virtual Machine' to iSCSI vSwitch and adding another virtual NETWORK card on the computer virtual - attached to the newly swanky group harbour - with an IP address in the range of iSCSI.

• issue of configuration for the store of data/LUN iSCSI

  Hi all!  I am all new to VMWare and iSCSI, and I have a question about data warehouses regarding being mounted on an iSCSI target.

  Here's my setup.  I have a Dell PowerEdge R810 connected over a link to 10 GB dedicated to a Dell PowerEdge 2950 that I use as a SAN.  The R810 has no hard drives in it, it starts ESXi on a redundant configuration of SD card integrated into the server.  My SAN software is Server 2008 Enterprise with Microsoft iSCSI software Target 3.3 installed.  I created target 1, LUN 0, 800 GB .vhd file sitting on a NTFS partition and set up a store of data on it in VCenter.  The data store is the size of the entire iSCSI, 800 GB target.  I have my first virtual server up and get 50GB of space between the data store.

  Here is my question: can I create several virtual machines using the data store I put in place?  I know it sounds like a stupid question, but my concern comes from some reading I did on several computers, access to a single LUN.  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  Issue of bonus points:

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  Thanks for your patience with a new guy.  I searched and read for hours, and I could have read too much so I thought that I had just askt experts.

  Hello and welcome to the forums.

  Can I create several virtual machines using the data store that I put in place?

  Yes.

  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  No, you should be fine.  One thing to keep in mind is that the Windows/MS iSCSI target is not a supported storage solution.  There could be problems of scalability with iSCSI Windows/MS, but you'll be fine in a VMware perspective.

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  You could, but I personally would put in place a different data store on another iSCSI target.

  Good luck!

• Network with TOE iSCSI adapter

  I'm going to my old server as a storage server and connect via iSCSI to new ESXi server. Former storage server will be linux with iSCSI software target machine. The question is: does make sense to have the NIC with TOE iSCSI on a new server if it is software target on the other? If so, then should I upgrade old server network adapter to one with TOE iSCSI? Or just buy without?

  In this case, you can buy not NIC with TOE, iSCSI HBA with TOE, but, and there is no reason.
