ISCSI HBA con problemas y el failover

• iSCSI HBA + SAN, EqualLogic

  I have a new deployment, I plan.

  I'm looking at a PS6000VX EQL - dual controller with 4 x GBIT by controller cards. In my opinion, it works in an active/passive configuration.

  What is worth of watching me iSCSI HBA with this sollution? Cost is not a problem at all. Performance/reliability/redundancy is.

  I understand with HBA you can multi-path, but with a sollution active/passive is not treated by the table flipping? In that it switches IP on assets of Eve? (with equallogic?)

  Any comments?

  Do you have more information in this plugin MPIO?

  Is still in beta... so there is no official information.

  But will probably like the MPIO module for the Microsoft iSCSI initiator (which can use all the links on the active controller).

  There will be a big reason to go with the software on a HBA iSCSI initiator?

  It's cheaper

  And you can license to have the company more

  understand my reading that Equallogic doesn't have any special configuration as the SP manages failover.

  Right.

  Just remember to follow the proposed (by Dell) network topology if you use two switches (instead of a main switch with 2 stacked modules).

• Free hypervisor ISCSI HBA

  I'm looking for a hba iscsi which will work without problem and can be which is not expensive.

  Can someone advice me?

  Thank you.

  Yes, either check with the seller (that should know) and also take a look at VMware HCL to http://www.vmware.com/resources/compatibility/search.php?deviceCategory=io to see what iSCSI HBA is taken in charge for the different versions of ESX (i). There are also a couple of network server adapters, which can be used as iSCSI HBA, but some of them do not support frames.

• 10 G of copper iSCSI HBA / NIC?

  Because of vSphere 4.1 support 10G copper iSCSI HBA / NIC? It will support VSphere 5? If it is supported, which it will support?

  I agree with golddiggie on the Intel stuff.  There are cards that work well, you can also search the forums here some of the brands and models to see what problems people have met with them and the possible configuration changes that can help.

  If you have found this helpful at all prices please points using the correct or useful!  Thank you!

• iSCSI HBA on 3.5 U3 - vswitch installation is required

  I have ESX 3.5 U3 installed on an IBM 3850 with 2 QLogic is installed.  I did the firmware updates and ESX recognizes the HBA as storage adapters.  My problem is this, all my other ESX servers use standard NIC so I create a second vswitch for my iSCSI LAN and add 2nd NETWORK card for guests of this switch.  When I go to create a my vswitch iSCSI only available adapters are my cards, I can't add the HBAs.  How can I configure a vswitch on my iSCSI LAN that will be using / accessing the HBAs?

  If you use the initator MS iSCSI inside your virtual machine then you will need to use regualr NIC you wouldn't be bale to use iSCSI HBAs as they are used by the vmkernel to access the iSCSI SAN

• iSCSI HBA NIC teaming on recommended vSS?

  Hi all

  Just curious when you have two iSCSI HBAS do not use VMwares iSCSI Software initiator you still need to make sure that the following configs are in place? :

  Vmk1 - iSCSI0 - VMNIC1 - Active

  VMNIC2 - not used

  VMK2 - ISCSI1 - VMNIC2 - Active

  VMNIC1 - not used

  Or can you just leave it as active/active with Orig Port ID?

  There is much info on what to do with the software iSCSI initator but what when you have HBA?

  Yes. I added a link to my previous post which illustrates the configuration.

• Hardware iSCSI adapter connection problems

  HP DL385 G7 with 2 HP (Broadcom) NC550SFP Dual Port 10 GB adapters. ESXi 4.1 U2

  You try to bind material load NC550 adapters to the good network card.  When I list of the HBA association and the NIC.

  esxcli - list of server servername swiscsi vmnic vmhba d #.

  It displays the physical NETWORK card bad example vmnic0 which is a 1 GB card NETWORK configured as the VM network and network management

  I had previously assigned iSCSI Software for the two vmnic adapter in the NC550SFPs.  However when I list the cards for the iSCSI HBA software, it lists each NIC in the system.

  Tried to simply bind the correct physical NIC to the iSCSI HBA hardware

  esxcli - add a server servername swiscsi nic - n vmkx d vmhba #.

  where vmkx is the physical NIC for the NC550 and the vmhba # is the HBA for the NC550

  and it failed with: failed to add a network card

  Attempted to delete the incorrect association

  esxcli - server servername swiscsi nic remove - n vmkx d vmhba #.

  where vmkx is the nic which was displayed in the list for hba named vmhba #.

  and he returned: NIC is not bound

  Do not know where to go next...

  Hello

  In addition my property would be to disable the iscsi Software initiator - you want to use only the hardware iscsi adapters, don't you.

  Mixing software and hw adapter is not recommended method here, as far as I know.

• adding targets to send the iscsi hba software.

  Hello

  I am trying to add dynamic send targets to a host ESX 3.5.  Here is the code I wrote, but there is something wrong with it.  Someone at - it worked with this before or would be able to tell me where I'm wrong?

  Thank you

  Matt

  Here is my code:

  My $iscsisvr = Opts::get_option ('iscsisvr');

  My $hostview = Vim::find_entity_views (view_type = & gt; "HostSystem");

  My $host_ss = Vim::get_view (mo_ref = & gt; $hostview - & gt; configManager - & gt; storage system);

  My $host_sv = Vim::get_view (mo_ref = & gt; $host_ss - & gt; storageDeviceInfo);

  My $host_hbaview = Vim::get_view (mo_ref = & gt; $host_sv - & gt; hostBusAdapter (bus = & gt; "32", device = & gt; "vmhba'));

  My $sendTargetSpec = HostInternetScsiHbaSendTarget - & gt; New (address = & gt; $iscsisvr);

  My $addSendTarget = AddInternetScsiSendTarget - & gt; New (iScsiHbaDevice = & gt; "vmhba32", target = & gt; $sendTargetSpec);

  $host_hbaview - & gt; HostInternetScsiHba (configuredSendTarget = & gt; $addSendTarget);

  Find one or two things:

  Probably, you won't need the storageDeviceInfo unless you want to verify that the iscsi HBA is configured (which may not be).  You also do not get a view of the hostBusAdapter.  You must remove that as well.

  You can delete the following text:

  my $host_sv = Vim::get_view(mo_ref => $host_ss->storageDeviceInfo);
  my $host_hbaview = Vim::get_view(mo_ref => $host_sv->hostBusAdapter(bus => '32', device => 'vmhba'));
  

  There was a spelling error in AddInternetScsiSendTargets (you have it as AddInternetScsiSendTarget).  In addition, this method is off your HostStorageSystem, in this case, $host_ss.  You need to perform a rescan after adding the target as well.

  Change:

  my $sendTargetSpec = HostInternetScsiHbaSendTarget->new(address => $iscsisvr);
  my $addSendTarget = AddInternetScsiSendTarget->new(iScsiHbaDevice => 'vmhba32', targets => $sendTargetSpec);
  
  $host_hbaview->HostInternetScsiHba(configuredSendTarget => $addSendTarget);
  

  TO:

  my $sendTargetSpec = HostInternetScsiHbaSendTarget->new(address => "$iscsisvr");
  $host_ss->AddInternetScsiSendTargets(iScsiHbaDevice => 'vmhba32', targets => [$sendTargetSpec]);
  $host_ss->RescanHba( hbaDevice => "vmhba32");
  

  I would probably change your code to something like the following:

  sub FindVmhba32
  {
       my $HBAs = shift;
  
       foreach ( @{$HBAs} )
       {
  
            if ( $_->device eq "vmhba32" )
            {
                 return $_;
  
            }
       }
       return undef;
  }
  
  my $host_ss = Vim::get_view(mo_ref => $host_view->configManager->storageSystem);
  
  my $host_sv =  $host_ss->storageDeviceInfo;
  my $vmhba32 = FindVmhba32($host_sv->hostBusAdapter);
  
  unless (defined $vmhba32)
  {
       Util::disconnect();
       die "Failed to find ISCSI HBA ('vmhba32')";
  }
  
  my $sendTargetSpec = HostInternetScsiHbaSendTarget->new(address => $iscsisvr);
  $host_ss->AddInternetScsiSendTargets(iScsiHbaDevice => 'vmhba32', targets => [$sendTargetSpec]);
  $host_ss->RescanHba( hbaDevice => "vmhba32");
  

  You can drop the FindVmhba32 subroutine and simply use a block around the AddInternetScsiSendTargets eval.  You can throw a few errors, one of them is not found if the specified HBA is not found.

• iSCSI HBA adapter

  Been having a lot of problems with a repressive IBM X 3650 M2 and its compatibility with the UEFI.  The problem I have now is that one does not see the storage and was curious to know if HBA will really hurt.  I know that sounds like a stupid question, but it's the only thing I have left.  I checked, double checked, m and triple checked all the settings and they are correct.  Swapped cables, exchanged ports and after a new analysis to show anything.  The other adapter is fine and the only other thing that I've been swap cards around.  Did not have to open the box.  Are there other things I can try to see why this HBA adapter can not see the storage?  It pings very good also.  The wuggestions are welcome. Thank you

  Perry

  Is there a firewall between you and the iSCSI storage?  Using CHAP?  Have you checked that the initiator is set up for CHAP authentication on the storage side?  There could be lots of things, even a HBA bad as you mention... but if it can ping successfully I guess it's a problem of configuration somewhere.

• Problem of cluster Failover MS after physical RDM conversion to VMDK

  Hello

  Last week I had to migrate 7 x 2-nodes virtual MS Failover clusters to a new data center. All clusters have been configured with the configuration of the cabin and all shared disks were in physical RDM mode.

  The target data center does not RDM disks so I had to convert all RDM disks VMDK files and use config before the migration of the IPC.

  I used vmkfstools to convert VMDK eagdrzeroedthick RDM files.

  5 clusters have been migrated successfully, but two cluster got strange question even if the procedure for all groups was the same.

  So in two groups, I have a problem where the second node in the cluster can not put online some of the shared disks. The first nodes in the clusters have no problem with the disks/SSP.

  But when I try to failover of all services, the second node may not bring online disc 1 or 2 shared, even if she can put the other shared disks online.

  VMKernel.log is not errors or warnings. I checked the configuration of virtual machines and everything seems OK.

  Any ideas what I could check?

  Just in case anyone else is facing the same problem.

  I could not find the root cause of the problem, even if it's without a doubt the conversion that triggered the problem. However, we found quite a simple solution - added new shared VMDK files, copied the files over and replaced the defective discs.

• Instant con problemas

  Hola a todos

  Tengo 4 servidor virtual montado in una cabia discos back servidores con ellos 3 don't me dan problemas al building snapshot pero ellos uno una me devuelve el siguiente error "a configuration invalid snapshot was detectec" ¿Alguien sabria como solucionarlo?

  A greeting is gracias por anticipado.

  Hola Arcige,

  Someone made changes in the config of the VM mientras el instant Alicia walked in? Typing ahora mismo en esa VM UN instant walked in?

  Entrada prueba a hacer UN clon of the VM (con the VM parada) y ver el clon en TR not you pasa.

  If no you can try United Nations work around:

  -Para the VM

  -Adhere to consoled her del ESX Québec tiene ahora the name VM y teclea:

  VMware-cmd - l

  Con esto veras una lista las rutas of VMs is.

  -In the VM directory el Metete, y desde dentro el, localiza ficheros .vmsd, ellos uno are el you estara causando problemas (ignored because). El that sea en Cuestión, lo cambias in number:

  MV orig.vmsd - wink wink - orig.vmsd.orig

  -Una vez hecho esto arranca e VM brought hacer a snapshot.
