• How to save and reuse network and iscsi on reformatting configuration?

  We have all the physical servers to reformat and reinstall vsphere (Enterprise edition).

  We would like to avoid to rebuild all the configuration network and iscsi for each physical machine.

  Is there a way to save the configuration and apply again to the reformatted Server?

  Thank you

  Hello

  You can save your configuration with the command vicfg - cfgbackup.pl - Server

• 2 questions - group leader and iscsi

  We have a unique PS6500 of the firmware 6.0.5. From 3 days ago, Archbishop Grp freezes when I click on the member icon. I could go into all the rest of the GUI with no problems. I got the firmware installed for about a month, so I don' t think that is the problem. Has anyone else seen elsewhere?

  2nd edition - we have vmware hosts connected to QE through private switches. Vmware hosts have separate vswitches for vmotion and windows iscsi volumes. VMotion is on 10.2.0 subnet and iscsi volumes are on 10.2.1 subnet. The EQ is on 10.2.0 with a 255.255.0.0 mask. The switches are set with the VLANS separated for iscsi and vmotion.  So far in Grp Mgr, I allowed on each volume 10.2. *. *. I started to try to change it so that the vm volumes only allow connections from 10.2.0. * (vmotion subnet) and volumes windows only allow connection of the 10.2.1. *. Currently, I do not use chap or iscsi initiator to limit. Here is an example for a windows volume.

  But here is what I get in the Connections tab for this volume, even after a new analysis of storage host adapters:

  So either I completely ignore the setting of the limits of intellectual property, or my EQ has a problem. Shouldn't I have the 10.2.1 connections to this volume?

  Any ideas? Thank you.

  None of the fixes listed in the 6.0.6 release notes apply to my EQ,.

  BTW, you can add the ACL CHAP to the EQL live volume.  This will not affect existing sessions.  Just make sure that you first create the CHAP user on the table.  Then after setting the ACL volume, set the iSCSI initiator ESX to use CHAP.

  If you take a look at the RPM, you can find a few Commons left default setings.  There are some that will improve performance, other stability.

  vMotion has not EQL access at all.  It's strictly for compose the image memory of a computer virtual from one host to another ESX host.

  Storage vMotion includes EQL, but it does not use the port of vMotion to do anything.

  vMotion traffic must be completely isolated, because the content in the course of the transfer are not encrypted.   So no VM Network exchanges should be on this vSwitch and the physical switch should be isolated too.

• This virtual machine to become protected vsphere HA and HA can not try to restart after a power failure

  I got a 5.1 cluster with some problems HA.

  a few virtual machines are showing this

• vSphere replication and RDM

  Hello

  I have a site that I put in place which has Windows 2012 R2 invited with RDM in physical compatibility mode.  When I go through the wizard of replication vSphere for these servers I can configure replication for the comments and as expected I can not set up for the RDM (which is fine, I have those covered by the SRA) but on the last stage it errors with the following:

  Physical RDM mode is not supported by vSphere replication and there is a known issue, you cannot configure replication for VM with RDM physical mode even if you exclude this record of replication.

  Check the release notes: VMware vSphere replication 5.5.1 Release Notes

  Cannot configure a virtual machine with disc RDM in physical mode even if the disk is excluded from replication.

  If you configure a replication of a virtual machine with the physical mode, the following error message may appear:

  VRM Server generic error. Check the documentation for any troubleshooting information. The detailed exception is: HMS can not set disk UUID for disks of VM : MoRef: type = VirtualMachine, value = , serverGuid = null'.
  

  Workaround: No.

• FC and iSCSI

  I have an IBM Blade Center with 4 blades running enterprise 5.1 ESXI.

  The blades are connected to storage via FC (Fibre Channel) switch.

  I added a new SAN at the center of the blade, but due to some unexpected port licensing problems with my Cisco MDS 9000 FC switch, I can connect only one of the 2fc connects to my blade right now.

  The SAN also comes with ISCSI, so my question is, can I have a put in place with FC and ISCSI multipath?  or is it a bad idea?

• VSphere APIs and compatibility ESX

  I've implemented the backup of a VMWare VM and application of recovery with vSphere API and VDDK. The development has been done entirely on 5.0 ESX servers. The following discussion provides an overview of how I implemented the restoration.

  http://communities.VMware.com/message/2130483#2130483

  When another person has tested my application, he noted the rollback feature does not work. When I've debugged, I found parameter spec unit to CreateVM_Task behaves differently 5.0 Esx to Esx 4.0. In the case of Esx 5.0, it works perfectly, where as in the case of Esx 4.0, none of the devices that I fill before the CreateVM_Task is created and the restore fails because of this.

  How can I understand the compatibility of the Esx and the vSphereAPI versions? I assumed that the SDK should be retro-compatible with Esx Server? Can someone shed some light how this problem can be solved?

  Thank you

  . / Siva.

  Hi Siva,

  That sounds good, maybe, we'll get you going even faster than I expected:

  but in general, the more recent editions of vSphere will support previous editions of vSphere. vSphere 5.1 supports vSphere 4.x and 5.0

  the only thing being that if new properties are added to a data in 5.1 object then you can not use in 4.x or 5.0.

  It seems to me that your code is based on 5.0 WSDL generated by gsoap stubs. It is ultimately you generate SOAP requests that are supposed to work with 5.0, 5.1, 6.x one as well now. Yet, when he delivers the SOAP messages to 4.x, it is likely that you include a property that is not defined in the WSDL of 4.x.

  Attached is a diff of the definition WSDL VirtualMachineConfigSpec of 4.0 to 5.0 Quick. Look at line 27 and following

  ====
        !>

  28              
  

  Here, you can see that numCoresPerSocket property was not available in 4.0, but was added in 5.0. It is also what we said the documentation centre: for vSphere API 5.0.

  You declare that numCPUs is affected but memoryMB not. Between the two numCoresPerSocket has been inserted to 5.0. It seems that the 4.0 Server reads your VirtualMachineConfigSpec until numCPUs then encounter numCoresPerSocket and abandoned.

  So far my theory.

  What I don't understand is that this seems to happen in silence as you don't declare any exception. Yet, says William

  As you can learn from the attached diff we serveral more properties that have been added to the 5.0. Might well want to comment on all those in your current code and re-run CreateVM_Task against server 4.0.

  Perhaps this might solve the problem.

• Recommend bridge SCSI and iSCSI

  Hi guys,.

  Currently I have an ADIC FastStor 2 tape auto-chargeur connected to a physical machine, Backup Exec 12.5, which backs up our running VMS with internal agents. Our ESX host running ESX 4.1, running on servers of 4 HP DL380G5.

  We are looking into converting to a more focused VM disk backup over the next 9 months, but we have a short-term obligation to upgrade our current solution quickly so that we can remove the material (it has long been out of support and our backups start to fail). To this, looking at a quick upgrade to BE2010 R2 (since we have already supported) and put us the media server on a virtual machine. Remains to be seen how to connect to the tape library. A SCSI and iSCSI Bridge seems to be the best option to do it quickly and with headache less.

  Someone at - it experience with these devices? Recommendations for an individual? The current tape drive uses a connection of Ultra2 SCSI wide 68 pins.

  Thank you

  .. .After research forums and seeing the difficulty that people have, I wasn't convinced.

  The positions of 'problem' I see the most are those who use cards non - of Adaptec SCSI and / or not parallel SCSI drives.  The most recent posts I've seen are for tape drives, SATA or SAS drives.  Basically trying to use 'new' band players, rather than reuse the 'old' band of readers.

  Quick is the main concern here. The money is available, it cannot simply be a ridiculous amount since it is monstly going to be throwing next year (otherwise I'd just go straight for an iSCSI tape library).

  Then I recommend the SCSI card because it would be cheaper than a bridge.  Or if you have an existing workstation you can re-tasks to host your tape drive for awhile so that get you the rest of your new backup equipment.  Used & refurb workstations can be made for well under $ 500 and often as low as $200 and would be more powerful enough to accommodate a tape drive.  Because you can reuse the workstation after obtaining new equipment, you could get something more than the bare minimum for this project.  Maybe it's a better use of $$$ instead of a bridge iSCSI that you go to "throw".

• VCB server with both FC and iSCSI connections

  Hello.

  Anyone know if a VCB implementation that has the FC and iSCSI LUN presented to the proxy server is possible/supported?  I see no technical reason that it wouldn't work, but I'm trying to understand whether or not this is a supported configuration.

  Thank you!

  I don't see why that would be a question of a standpoing of features, but if you didn't mind the performance hit you just the business day following mode of transport and not worry present LUNS.   I guess that maybe in the same way hotadd would work as well.

• Possibility of setting up new vSphere 4 and pass the ESX 3.5 hosts?

  The upgrade path makes me nervous (am I too paranoid?).

  In any case, I have enough material and storage SAN to configure a new vSphere environment.

  Is it possible to install a new enviornemnt and separate vSphere 4 and then migrate the 3.5 environment hosts? The doc has always start with VC upgrade to version 4 and be careful not to break stuff...

  I actually finished a project a few days ago in this respect. I deleted the machine virtual old inventory, moved with the former VM of the LUN to the storage for the new environment group and added to the inventory again. Of course, if you do not use the same storage, it will be more in depth, but it certainly can be done. The plan was to do what weinstein said in his post, regarding the old host to the new Victoria Cross add, but I move the first LUN and had to finish like I did. It went well and I don't have problems with the virtual machine again.

• 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

  Kind regards

  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.

• vSphere 5 and Dell Equallogic iSCSI

  Hi all

  I need some suggestions on how to implement my iSCSI network

  I habe 2 x power R520 edges with 2 network cards to edge, 4 x PCI Nic and 1 x Dual Port Nic Cards-> network so 8 total

  and an Equallogic PS4100 with 2 controllers and 2 network cards on each controller

  I have 2 Dell switches for my iSCSI network.

  The address of the Equallogic MGMT is 10.10.1.100

  The group IP address is 10.10.1.101 - or should these IP in the iSCSI network

  My iSCSI network should be

  192.168.1.x / 24

  do I need to a single network or do I have to use 2 different networks in order to obtain the failover job.

  I plan 2 or 4 NICs for iSCSI vmkernel traffic - what do you suggest?

  If I use 4 network cards - use 2 vmkernel ports with 2 links and aggregation of links on the switches? Or can I use 4 ports vmkernel and round robin?

  ESX1

  vnmic0 192.168.1.1

  vmnic1 192.168.1.2

  ESX2

  vnmic0 192.168.1.3

  vmnic1 192.168.1.4

  EqualLogic

  eth0 192.168.1.5

  eth1 192.168.1.6

  ESX1 + ESX2

  vmnic0 - iSCSI01

  vmnic1 - iSCSI02

  SwitchA

  vmnic0 Esx1, vmnic1 ESX2, eth0, eth1 ControllerB controlled

  SwitchB

  vmnic1 ESX1, vmnic0 ESX2, the controller has ControllerB eth0, eth1

  Do I have to master two switches?

  concerning

  Bestfriend

  Hello

  I recommend 2 virtual switches with 2 network cards in each. Multipathing in fixed for each switch if it's an active-passive array and Round Robin if it is an active-active array.

  1 VLAN should be fine.

  MTU = 9000 in all the components of your infrastructure iSCSI (jumbo frames).

  Try to have HA in each part of your infrastructure and you sure you don't have 1 vSwitch connected to the 2 ports on the same HBA and using the same switch...

  If you have the option to make the "fast track" in your switch, do it.

  CHAP authentication more secure, you can (if initiator software, I think that they are, mutual CHAP)

  You don't need chest 2 switches.

  Try to keep your number of VMs distributed among your LUN (to not collapse them with SCSI reservations)

  That's all I can think of at this time. I hope this has helped you! If that were the case, do not forget to assign the corresponding points, so we are all winners!

  Kind regards

• ESX iSCSI & LACP

  I have a few questions I wanted to ask and try to learn before you start this project. Currently, we have two ESX servers, located on a single switch. Our virtual machines use different VLANS by customer.

  Here is going to be our new configuration I have planned:

  • (1) HP StorageWorks P2000 G3 iSCSI SAN
  • (2) cisco/Linksys SRW2024P switches (supported VLAN, LAG, LACP, frames Jumbo)
  • (3) HP Proliant DL360 G6 servers
  • Each server has 3 network cards
  • (2) routers of Sonicwall

  Exactly how do redunandcy off the iSCSI traffic? Using LACP on the switches I would connect the right set of themselves? So 1 Port SW1 goes to SW2 Port 1 and the same for Port 2.

  Then I would be on the side of ESX team two NICs together for iSCSI traffic. I would use IP Hash. I would like to connect NIC #1 to SW1 and NIC #2 in SW2. So, technically, I could unplug on NIC #1 and virtual machines must be able to run because of the several paths right?

  If I'm away, please let me know. I want to be able to lose a single switch, losing a NIC and continue to operate without a hiccup.

  Hello

  Attach a large document to help you implement the P2000 with vSphere.

  It is generally recommended to use multiple paths instead of collage/team.
