• Hot Add Remove lun fails in rescan periodical at the time of the withdrawal, although the path is marked as DEAD as planned

  So we run the hot add and remove cases from LUNs in the certification for ESX 5.5 with Workbench 3.0 kit

  The hot add succeeds to the two manual add and periodic scan... Deletion succeeds manual extraction, but a failure in periodicals rescan same removal so it lists the path out of SERVICE.

  [August 26, 2014 20:24:27: HOTADDREMO] [0] ERROR: LUN is found not deleted after periodic rescan on the first server

  
  

  So I checked the Vmware perl code that performs this case... it is available at /opt/vmware/VTAF/storage50-cert/VTAF/Test/Storage/StorageCert/FVT/HotAddRemoveLUNs.pm

  
  

  Sub RunHotRemoveTest

  {

  .....

  # Remove LUN only cause death I/O path.  It does not delete the LUN.

  # Evaluate for the dead I/O path.

  $deadPathFound = "NO";

  LogInfo (channel = > $channel, MSG = > "Check the path to remove LUN on $server");

  foreach my {$lun (@lunListBeforePeriodicallyRescan)

  #my $lunObj = $host2HbaObj-> CreateScsiLun (name = > $lun);

  $cmd = "esxcfg-mpath - bd $lun";

  My $cmdObj = new VTAF::Framework:Core:Common:Command)

  Home = > $host2Obj-> GetName();

  Cmd = > $cmd);

  my $rc = $cmdObj-> GetReturnCode();

  my $cmdResult = $cmdObj-> GetStdout();

  my $cmdError = $cmdObj-> GetStderr();

  If ($cmdError) {}

  $deadPathFound = "YES";

  LogInfo (channel = > $channel, MSG = > "mpath command returned: $cmdError");

  LogInfo (channel = > $channel, MSG = > "$lun is deleted after periodic rescan");

  }

  }

  If ($deadPathFound not 'YES') {}

  LogError (channel = > $channel, MSG = > "LUN is not deleted after periodic rescan on the $server");

  return FAILURE;

  } else {}

  LogInfo (channel = > $channel, MSG = > ' delete hot with periodically rescan PASSED on the $server ");

  }

  }

  So if you see the code above, Vmware itself expected the path to show the death, but they perceive three error codes for the output of esxcfg-mpath - bd < lunname >

  I think they expect an error to return to $cmdError... But looks at though it lists the path as DEAD, she returns to success... So the $deadPathFound is always set to no. He goes into the path of "not YES" and not the test case...

  I would like to open a folder from supported with VMware, but before that I would like to know if someone has faced this problem and had this problem of VMware using any patch in their Workbench... Or if any new workbench has this problem fixed...

  We are using Vmware Test Manager: 3.0.0 - 1610638

  So basically had the question warm Add Remove Lun. It is a problem in the ESX version we use and scripts of WorkBench. If we use the build ESX GA this would have worked. ESX changed the behavior of the command in version 5.5 of GA to a new approach and then back to the old approach again in 5.5 Update1.

  The version we use are two versions higher than the release of GA... Therefore, the behavior of this command is different between these two versions.

• UCS hot add/replace memory/CPU

  Hello. I know on cisco UCS C460 we can expand the amount of memory using memory riser cards. Memory riser cards are hot-swappable. This means that when I run Win2008R2 Datacenter Server c460 I can hot add and replace the memory riser card memory?

  Can I hot replace memory on the motherboard slots?

  What UCS server models are supported CPU hot add/replace?

  Dmitry,

  Yes the risers of memory are hot-swappable, so assuming that the bare metal OS can support memory added to hot it will work.

  There is no DIMM slots on the motherboard directly on the C460.  Memory riser is only motherboard for memory interfaces.

  There is no such a thing to my knowledge as an addition to hot CPU on all Cisco platforms.

  See the Installation Guide HW for more information:

  http://www.Cisco.com/en/us/docs/unified_computing/UCS/c/HW/C460/install/replace.html#wp1160169

  Kind regards

• Hot add RAM through workflow

  I'm working on a workflow to change the RAM/vCPU for a VM given, ideally using hot add, and it seems to be running into a problem with the memory part. My plan is to just get something working for now, and then add the logic to treat various conditions (hot don't add not activated/VM under tension, etc.).

  So far, I have a relatively simple workflow (see below). The virtual machine in question has 2 GB of RAM and is turned on.

  

  I looked also directly using the workflow change in RAM, but it gives me the same error. I use vSphere 5.5, vCO 5.5.2 - of ideas?

  EDIT: I should mention that my test VM THAT hot add activated, it is supported by the OS, I have the license appropriate, and that VMware tools are up-to-date.

  I found the problem... it turns out that Linux 64 bit guests with less than 3 GB of RAM can only warm - add up to a total maximum of 3072MB. If you're at 3071 MB, you can add only hot 1 MB. If you're 3073, you can add warm all the way up to 20 GB if you wish.

  There is a KB for this: KB2008405.

I work in a hospital and shut down a virtual computer is not possible to activate these functions.

  You can enable the feature add hot power-CLI, but you will need a restart in order to reload the new configuration.

  Here you can get the detailed information in the present.

• Hot add RAM Option not visible

  I upgraded the VMs tools and equipment (v7), but do not see the option to add hot RAM.

  The attached doc shows a Windows 2003 Server operating system with the options of the virtual machine.

  I don't see the line that allows me to turn on the option.

  I have to do something else to enable the option Add Hot for RAM?

  Thank you

  You must add pwer down virtual machine initially to turn hot.

  On your second photo screen you can see hot add is disabled and you cannot change this setting only when the virtual machine is turned off.

  1. turn off your virtual computer, then change the settings.

  2. go to Options > advanced > memory/CPU hotplug

  3 activate hot-memory add to this virtual machine.

  4. turn on the virtual machine and the test.

• VCB Helper for SCSI Hot-add and FULL-VM backups

  Hello

  I would just ask all those who are already using the computer virtual configured as a helper of the VCB for SCSI Hot-add if it can be used to make the full-VM image-level backups?

  We currently use a physical VCB server to make the backups weekly full-vm image via the SAN with a backup agent software to capture the day-to-day changes.

  As part of our current DR, let's use SRM and the Faculty linked VCB a VM and reduce the number of physical servers, we need to reproduce the site of DR looks tempting.

  Look forward to your responses,

  Craig.

  Craig-

  First of all, welcome to the Forums!

  To answer your questuion, Yes, running VCB in addition to hot mode supports FullVM-level backups and file. However, the SAN mode is the most effective way to backup of virtual machines.

  Think about why you are replicating your data center: for a fast recovery. If all virtual machines are replicated, there should be no need to restore from a full site FullVM disaster backup. With replication, VCB and agent of the base backups are recovering after a local disaster, as a virtual machine crashing or someone deleting a file (or even a virtual machine). It is also for archival purposes.

  Once you have recovered from a disaster, the VERY next step should be to make a clean backup, so VCB is required on the site of DR. If you are looking to reduce the material on the site of DR, make the VCB proxy and the server vCenter one machine virtual on the DR site, but let the VCB as a medical examination on your production site. The end result will be FullVM backups via SAN to a physical server and ' rescue' VCB proxy in a virtual machine on the site of DR.

  As a warning and to add to your confusion: o), some people find that hot add mode is faster than the SAN mode, depending on the setting of the physical server VCB and SAN...

  You can also study the esXpress, allowing you to perform backups on a VMFS volume. This could be replicated to your recovery site and serve your backup off site location.
