• SRM using the issue of replication VRMS vSphere

  Hi guys,.

  Basically normally when using vsphere replication, if you lose the VRM, then you cannot recover your virtual machines.

  'With the VRMS device in offline mode, it is not possible to recover virtual machines with vSphere replication. There are some items of third person out there that suggest that it is possible to manually change the files to the target location that make up the replica and recover a virtual machine. "While this is possible, I do not recommend relying on this method of recovery, because it's a very manual process and, above all, not supported by VMware "

  Am I right in thinking that when you use SRM with replication of vsphere, this isn't a problem that you can 'force' recovery with MRS... .where is it always going to be a problem?

  This is a question published iI in Re: 1 primary replication running unit and 1 device running the module

  Cheers for the help guys!

  As Martin mentioned in the other thread, VR (and SRM when using VR) require work VRMS at the location of the target/recovery. To clarify your statement, read: "when using vsphere replication, if you lose the VRMS on the site of your target/recovery , then you cannot recover your virtual machines.

  With MRS is still a problem, but normally if your production site is affected it will not be an impact on VRM on the recovering site you will always be able to recover. Enforcement is where any operation is attempted on a protected site, so it's really for a different use case.

  Does that answer your question?

• SRM and the volume of replication

  Hi guys,.

  I have a client who seeks to implement the SRM.

  Available to the virtual machines are as follows:

  • system on vmfs1 VMDK

  • VMDK vmfs2-data

  • Windows swap file on vmfs3

  • VM vswap files vmfs3

  VMFS 1 & 2 are replicated but not 3. They tried to reduce the amount of unwanted changes block replicant.

  Have I reason to say that they would have to replicate vmfs3 (even just once) to allow sucessfully SRM protect virtual machines?

  Has anyone else came across such a configuration?

  Thank you

  Dougie

  You don't need to reproduce your vmfs3 volume.

  Just follow the procedure "avoiding replication of paging files and other transient data" of the SRM administration guide.

  Machine configuration virtual swap sit on no replicated data store is pretty easy, but the swap file configuration is not that simple and requires several steps to be completed for each virtual machine, including cloning VMDK, the VM configuration, operating system setup and configuration of SRM.

• VMware SRM Reprotect fails with Peer table ID provided in the SRM of entry is incorrect

  I have the following Setup

  Site-a.

  VMware vCenter 5.1 U1

  VMware SRM 5.1.1

  NetApp SRA 2.0.1P2

  FAS3140C - Data ONTAP 8.1.2P4

  Site-B

  VMware vCenter 5.1 U1

  VMware SRM 5.1.1

  NetApp SRA 2.0.1P2

  FAS3140C - Data ONTAP 8.1.2P4

  I created a Protection Group based at the A Site containing a single VM with a single vmdk disk on an NFS volume.

  The NFS volume is synchronous to the Site-B

  I can perform a migration scheduled to Site B, and then reprotect an another planned migration back to Site A, but then when I try to restore the reprotect again so that I am ready for an another Site-B recovery fails in the first step, configure storage for reverse Direction with " " - Failed to reverse the replication for impossible on the devices. SRA command 'prepareReverseReplication' failed. Peer table provided in the entry MRS. ID is incorrect check the newspapers RS to verify the correct peer array ID. "

  I see nothing on the files or the newspaper of SRM server logs to indicate that it is.

  This occurs for each Protection Group, I create this is not isolated to just this one volume.  I also tried with VMFS iSCSI volumes and get exactly the same results.

  If I create a Protection on the Site-B group I can get back to the Site-A and will not restore to fail to Site-B.

  Initially, I look that the issue I saw is that I could do a backspace, but could not perform a second reprotect because the SnapMirrors were left in the State of evil, but now I see that the problem is that I can't make a reprotect from Site A to Site B.

  I completely uninstalled SRM in both places, removed from the SRM database on both sites and started again but always get the same question.

  I actually IBM N series-N6040 controllers and uses IBM Data ONTAP and SRA. brand got a call open with VMware and IBM but not very far.

  Has anyone seen this problem before and got a solution?

  Now, I've identified what causes this problem and can work around it until there is a fix of NetApp.

  The issue was the name of the file on the recovering Site Server had the same name as the file server on the Site protected with a prefix to the subject, which in my case the recovering Site go was named NSERIES01 and the protection of the Site was DRNSERIES01.  Don't forget that I had already performed a failover and restoration for the protection of the Site was my original recovery Site, so yes give it the site protected for this Protection Group is DRNSERIES01 and the recovering Site has NSERIES01 on this.

  Using the task Reprotect is the first step is to call the SRA with the command prepareReverseReplication, which calls reverseReplication.pl, which is trying to verify the SnapMirror is broken.  It gets the status of all the SnapMirrors run on the recovering Site, which in this case NSERIES01.  It then goes through each of them looking for a match of the local-spin-name section: volume-name of the source of the snapmirror, for example for my test group was trying to match NSERIES01:NFS_VMware_Test, at this stage of the source of the SnapMirror is DRNSERIES01:NFS_VMware_Test which is correct, but because the script uses a pattern matching test it corresponds to NSERIES01 : NFS_VMware_Test to DRNSERIES01:NFS_VMware_Test as NSERIES01:NFS_VMware_Test is contained in DRNSERIES01:NFS_VMware_Test. It then checks if the destination of the snapmirror corresponds to the peerArrayID (that is, in this case DRNSERIES01) he does not like the destination, properly, is NSERIES01, and then reports that the peerArrayID is incorrect. If there is no match on the local-spin-name: volume-name of the source of the snapmirror, then he continues to check the destination of the snapmirror, and when it finds a match, it checks if the peerArrayID is the source of the SnapMirror, and if it checks the State of the SnapMirror is broken off.

  I've never touched the issue with the first reprotect because DRNSERIES01:NFS_VMware_Test is not contained in the source of the SnapMirror (NSERIES01:NFS_VMware_Test) and so it will be the next test of verification of the DRNSERIES01:NFS_VMware_Test in the destination of the SnapMirror, that he finds and then checks the DRNSERIES01 against the destination which is also to and finally confirms that the relationship of SnapMirror is broken-off.

  I had changed the volume on DRNSERIES01 a while ago because I thought that the question could have because of the volume being names the same, but I had changed with a suffix of _Repl on the end and so the script was always corresponding to NSERIES01:NFS_VMware_Test to _ReplNSERIES01:NFS_VMware_TestDR.

  I have now set my group of test as follows:

  Protected site

  Name of the file server = NSERIES01

  Volume name = NFS_VMware_Test_HMR

  Recovery site

  File name = DRNSERIES01

  Volume name = NFS_VMware_Test_EWC

  I can now get on the Site recovery, Reprotect, restoration, Reprotect and Fail-over again and continue achieving recoveries and reprotect again and again as often as you can re - save on VHS of Scotch tape!

  If the file on the Site B server had a suffix on its name instead of a prefix, for example, it was named NSERIES01DR, or had a name completely different then I would never hit this bug in the SRA.  I'll wait for NetApp fix SRA.  In the meantime I will be renaming all my volumes on the site of recovery as well as to avoid this problem.

• Vm management and SRM storage

  Hi all

  We are looking at SRM and ask if anyone had any guidance or best practices concerning how vm is organized in what concerns the underlying storage.  For example, it is recommended not to put the production systems on LUNS are replicated to the secondary site?  In other words, people leave their development/test environment of unprotected?  (I know it depends on the needs of the environment, but I was just curious.)  Is this a good practice application similar vm group (with their versions of dev/test/prod) on the same number of logic (or LUN) unit for portability?

  We are still at the planning stage and try to organize it better at the beginning.  The traps?

  Thanks for your help...

  -Rich

  I couldn't justify the cost of replication of resources outside production and protection with SRM, my replication technology requires licensing by the TB.

  I would be concerned with the provision of the machines vrithal data store!  I think that, for maximum effectiveness, what virtual machines should really be willing to better recovery of suport of critical applications.  I grouped the core infrastructure servers (A.D., LDAP, security, etc.), servers, messaging, applications by type of file servers (financial, intranet, internet, etc.) and have most of my databases placed on their own dedicated data store. This allowed me to reinstall all mail servers in the data center recovery for real proof validation tests.

  Go to this blog: http://blog.virtualtacit.com/2008/12/15/site-recovery-manager-minimizing-data-store-group-pigeonholes/

  The planning phase is certainly the most difficult part, but the time is well worth

• To better understand the SRM

  Hello

  We have 2 sites, each site, we have 4 ESX servers and on each site, we have a Clariion CX380 but everything is run by a single Virtual Center. All ESX servers are on the same VC data center. Finally, we have 2 physical sites that we have succeeded in one site.

  I know with the MRS, we need two VCs, one on each site, but we need two data centers in VirtualCenter? Why I ask this question is in fact we use MirrorView/S sync LUNS and we have LUN will concern because we cannot display the mirror and lun mirrored with the same uid when all the ESX servers are managed by a single CR.

  Can RS we manage this for us?

  I hope I'm clear with my problem

  Thank you

  Dominic.

  First of all the current version of MRS. can't a single VC use case, so if the customer doesn't move on this one there then you cannout currently using SRM. It has many disadvantages in terms of DR to use a single VC, so reason why SRM architecture uses two.

  When you have two SRM of the VC can work active / active and by that I mean you can have two production datacenters each replicating to the other, each acting as DR to another in the event of a site loss. SRM supports this configuration.

  From my experience of VMotion between sites with more current VC25/ESX35 never really gives you a lot in terms of use cases since it is really an option for customers which is DC are close together and even in this case you end up with is a virtual machine running on a site that is accessing its virtual disks at the other site not that desirable. Another point here is what to do with this way of working, you should also have areas of SAN that accepts the LUNS are accessible on the sites and also potentially beyond safe limits.

  Granted, I can see some obsucre use cases you want to to be able to vmotion VM on the site but nothing which makes it really interesting architecture this now, ok one day you might want to vmotion all around for the other site while you perform a hardware upgrade of hugh, but there are other ways this round with storage vmotion which give you even without interruption... Go ahead there is much more to come that will make vmotion over distance, a closer integration with the most interesting storage replication.

  When you're right, now I think that the more important thing to establish is that it really your customer wants, is it simply a solution allowing them to run two production DC so they don't have standing kit slowed to a place? If yes then MRS can do for them now in a configuration active / active. I find lots of customes think they must cross the vmotion site without really thinking through and without thinking about the implications for things like vCenter design, such as:

  The VC inventory / layout, be careful with the design, because everything is tense, to be very consistent and accurate with conventions of naming across all objects of inventroy will use the virtual machine

  DRS/HA settings, ensure that you know which VM is important and set the correct settings by VM for recovery. Unless you have N + 1 reserve capacity on each site, you will need to set up the parameters HA/DRS that highlight the most important line of the first VM and not end up in a situation of failure with all your virtual computer online dev/test and half the production of 'Down' of the VM because you have not set the correct priorities in HA. In SRM, it is something that the descriptors of recovery plan and you can control.

  Half brain, if you run the two sites as a big cluster HA/DRS ensure test you different failure scenarios, for example if the DRS (or manual VMotion) moving a bunch of VM is site1 to site2 but no failures that took place at that time there will now be left with contexts of CPU/memory/network of the virtual computer running on hosts to Site2, but accessing their VMDK on site1. This will work but is not always desirable from a perspective of latency (maybe no problem if enough bandwidth) However, what will happen if you suffer now Site1 disk failure, at this point the VM will not crash immediately Site2 and HA will take awhile to achieve those VMS have a problem. Try it and see, if you disconnect the storage for a virtual machine, the virtual machine will cling to life (assuming that IO is normal) for some time before a blue screen appears.

  Presentation of storage, if your customer wants the area sites to actually be 'open' to all ESX hosts, then check that understand you the implications of the ESX LVM parameters with regards instant / will of the disc. You will potentially have ESX hosts that might at one point access to a source and target LUNs at the same time if someone or something to change LVM default settings. As we discussed earlier, with architectures of SRM this is handled by RS as the SRM architecture, you would not have this kind of open area.

  Zoning by-law if the vsan / zones are truly open or guests as well then as certain events of fabric can be a potential pain. No event of thugs this RSCN disrupt both sites at the same time if all ESX hosts are on the same fabric open so be careful here. Not something that is too often but I have seen hurt some customers, usually comes down to bad HBA or cable can be a real pain to track down.

  VC / limits ESX, you build out of campus cluster design ensures the design will you quickly to reach the limits of what she has supported this concerning things like the maximum number of machines virtual/VC, max number of LUNS/ESX host, max number host ESX/lun/paths etc.

• Go with SRM or replication of VSphere

  Hi all

  I'm looking for a review here.

  In our current environment, 600 more VM is get replicated to disaster recovery site using third-party replication tool. As we intend to upgrade our whole environment to vSphere 5.1, we intend to use the replication of vSphere. We do not plan to use SRM at this point.

  We have two Vcenters, one for the env Prod and other for Dr. approx. We have our replication go on a dedicated channel for OC / 24.

  We are not woried about the Automation and do not come back to this point, MRS is not a choice at this point.

  Questions.

  1. with the limitation of 500 rehearsals (employment) for the unit of replication VSphere, ho we satisfy our need of 600 replications?

  2. can we use vSphere several devices of replication on each site (by vcenter) without using SRM?

  3. If it says 500 is the maximum supported, loads of work how I can configure on device for proper operation.

  4. should I consider SRM in this stadium? If yes why?

  Appreciate your help in this regard.

  Thank you

  Dembélé

  I see, but I guess that at least for a start and a conecpt evidence of the use of VR, a single VRS is enough. In addition, you can always high-end to SRM later and get better performance with the deployment of new technologies...

• Celerra + SRM and Replication manager

  Hi do anyone knows if its possible to integrate EMC replication manager a Celerra ISCSI / MRS. configuration?

  Replication Manager / SE, I read integrates with Virtual Center, puts the virtual machines in snapshot mode (kind of like the fact of vcb) and then starts the replication to ensure that everything is in order, I also thought with the module for VMware tools with 3.5 update 2 part tools VSS should quiese SQL and make sure that its happy before the virtual machine put in snapshot mode.

  I know with my current Celerra/SRM talks SRM server through the matrix of configuration manager and I expect actually has nothing to do with the real task of replication in celerra manager, im thinking it should be possible to use RM to kickoff between the Celerra replication and still have happy and work SRM.

  I'm way off here?...  If someone knows the answer to this... Please let me know... It would be much appreciated.

  Thank you

  Hello

  I write this as an EMC employee

  «Replication Manager / SE, I read integrates with Virtual Center, puts the virtual machines in snapshot mode (a kind of like vcb) then launches the replication to ensure that everything is in order, I also thought with the VMware tools with 3.5 module update 2 part tools VSS should quiese SQL and make sure that its happy before the virtual machine put in snapshot mode.»

  That's right – Replication Manager is able to do two things - integration with VMware Virtual Center to snapshots by car from Virtual Machines residing in a VMFS volume built on iSCSI.

  Following the call in Virtual Center agent proxy Manager VMFS Replication called Celerra to take the local snapshot. This snapshot can then be mounted to another ESX for backup (if this ESX host is running version ESX console with a backup agent installed in this console - backups for flat file VMDK) or simply to allow the machine virtual administrator to navigate in the data store is presented as a wink on the recovery of ESX host to activate the Virtual Machine defined in full file recovery. The vocation of VMware SnapShot Manager provides a consistent point machine to return where the virtual machine recovery fails

  Replication Manager can create replicas consistent application for such Applications a SQL and Oracle if these scores of applications based on VMFS volumes rather than posing as Raw Device Mappings. The caveat with this is that the volume presented to the Virtual Machine in question must be devoted to this Virtual Machine and a single VMDK file can be built on the VMFS volume) so you would need a volume for your logs, your database, etc. We call this use of replicas of "Virtual disk" case - confused I know

  So two use cases

  VMFS machine restoration for a set of Virtual Machines and integrated individual application VMFS volume consistent replicas for specific virtual machines with their scores of applications built on individually provisioned VMFS volumes

  I don't know why you want to use Replication Manager kickoff the SRM associated Celerra replication. the SRM model is basically continuous replication - i.e. an algorithm runs to determine to what extent the site of DR comes from the primary and push any data the differences across the wire. The bandwidth used for this can be strangled and demand

  Replication Manager leads Celerra replication tends to be regular and non-continuous

  With regard to your query on the integration of Replication Manager and SRM. I prefer to think to Replication manager and SRM for the moment be tolerant to each other. Replication Manager solutions I have just described are focused on the side backup and restoration of the entire equation of continuity of business and focused around that at the local level, so that the RS is more oriented toward the recovery room disaster

  I don't see that going forward, there will be more integration and I hope that Replication Manager may in the future serve to ensure consistency of the request as a level of additional service in the comprehensive proposal of SRM

• 10 improvement of the Windows path hangs on "place the external storage and press OK.

  Hello

  This will be my first post on this forum.

  A couple of weeks ago, I bought a Toshiba SATELLITE CL10-B-103 for my son. The CL10-B-103 has installed Windows 8.1. Tonight I plan to make the installation of the Windows 10 upgrade because Windows 8.1 announced that he was ready for the upgrade.

  The trial progressed slowly but smooth and without problems until now... As the laptop is equipped with only an HD 32 GB the trial upgrade was informed that I had to stick a USB key. After that, the trial continues slowly but smoothly, but who did not question because I had all night. However after the first reboot of the system when he was about 60 or 66% of installation of process this error message showed: place the external storage and press OK. It's very strange since the key USB has been removed at all and was still in the system. It is strange, is that both the OK button as the Cancel button are not selectable. Without passing by the touchpad, not a tab or an entry.

  Some community online Windows 10 post mentions that, via the BIOS, the system must be initiated from this USB key. I tried to reboot the system with DEL, F2 or F8, but I couldn't get into the BIOS and wasn't able to change the boot sequence.

  After each "restart" the same error message appears. It does not matter that the USB is in it or not.

  So, my conclusion is that my CL10-B-103 is suspended/East in a loop. I don't know how to proceed.

  Please, I can really use some help.

  Thanks in advance.

  Because it seems that I can not only edit/change a message I am answering my own post now...

  The problem seems to be resolved. When I was able to use the touchpad I could push the OK butten and the upgrade product now.
