SRM 5.5 with EMC SRDF. Full recovery but reprotect fails

Hi all

I am fairly new to SRM, but have been plugging away in establishing a new environment that uses:

vCenter 5.5 u1 (two Sites)

Solutions Enabler 8.0.1.0 - 1953

EMC SRDF Adapater (SRA) = 5.6.0 VMAX 20 k

EMC SRDF utilities SRA (and community VSI) = 5.7.0.2

RS = 5.5.1.8569

I followed documentation provided by Cody Hosterman ~which is great and got me almost to the end.  I was able to successfully switch (recovery), a virtual machine using a test Stimulus Plan from Site A to Site B. It was working fine.

We don't use TimeFinder (unauthorized) and so when we realize the expected behavior once happened that the SRDF link has been broken. The State of the R1 to Site A device has become write disabled. The device of R2 in Site B became read/write and the State of the device group is "Fail Over". It is in SRDF asynchronous mode.


To try to 'Restore' the group, I see errors relating to the configuration of the storage to reverse direction.

I checked the log EmcSrdfSra as suggested on the site now main SRM server and it seems that there is a mistake shortly after you have created a new consistency group.

I raised a support call with EMC with it directly as a first port of call, but it is in its infancy so I thought I would ask if anyone has any idea what could go wrong here. I have exhausted my googleFU skills and I'm at the stage of trying to get some eyes on the issue. I am happy to provide more information if necessary or to answer your questions - what someone might have.


Really hope someone can help!

Thank you!

Hello

I got some progress with this so I thought back and share what he needed to solve this problem.

Essentially, in our environment, we have a VMAX in each site. We have now two servers Manager array with Solutions Enabler (on a Unisphere web) installed. The reason is that we have a VCE Vblock and VCE provided a nursery table server. In addition, we have built our own for the purposes of the SRM and other similar things.

In essence, we do not configured new servers of facilitators of Solutions fully and missing GNS on them. We have also put in SRDF pairs and above all: GROUPS of DEVICES on the old managers table manually. These groups of devices répliquiez not to the new servers, but the other config (Volumes, etc.) have been! So SRM was trying to talk to our new boxes and only really get half the information on volumes and above all the volume groups.

Once we have properly configured device groups on each site for the Volumes that were used for SRDF replication, everything started working. Since then, we have been in and double-checked the configuration manager servers on new table and all is good. This solved the problems that I posted above.

I hope this helps someone in the future!

  • Pavilion dv7-4065dx: created a support of recovery-but it failed; Can't retry

    The original HARD drive has problems. With the operating system originally installed and my applications and files it would not conduct a CHKDSK /r

    Using Macrium Reflect, I couldn't image or clone the C partition. It kept failing due to disk i/o errors. I could save my user account and other important documents on a USB key. So, no loss of data.

    I ordered a new HARD drive and ready to make recovery disks and move everything.

    However, during the process create discs of Reovery (that I used Flash media - not disks), a message pops up saying that recovery media creation has failed.

    The flash drive was 64 GB, nine of its packaging. After the creation of recovery attempt, the flash drive is empty. No file has been written. Then, I tried to make records of recovery instead. But now when I run the app from creator of media I get the message 'media recovery has already been created for this computer. You can do this only once"(I've paraphrased... but basically - is it won't let me not try to create it again).

    So, I'm stuck. At this point, I want to just install Windows 7 Home premium (which came with the computer) and get all device drivers installed. I have the product key for HP on the bottom of the laptop. But, no way to install the operating system.

    What should I do now?

    If you create your HP recovery media when you first set up your computer and waited until the hard drive started to fail, it is likely that the recovery image has been damaged and led to the failure, you see. Because the computer is six years old, HP sells more recovery media for this model. Please see ComputerSurgeons.com Set #: 616567-002 for discs of HP recovery for your computer.

    If you have any other questions, feel free to ask.

  • Want J010dx m7: windows will not start until after full recovery of the system with new HARD drive

    Hello world

    I need help here.

    My HP envy m7 J010dx works perfectly with my original hard drive (1 TB).

    I am preparing a second HDD (NEW 320) as backup.

    I took off the Moose HDD (1 TB) and replace it with the NEW HARD drive (320GB) and try to do a full recovery of the system with the HP recovery DVD.

    After full system recovery and laptop computer needs to be restarted in order to continue, the laptop keeps restarting on the logo of windows 8.

    I think it says device not found Boot. Also a test using the UEFI tool material HP and all pass.

    Replacing the NEW HARD drive with the original of the old HARD drive and it start normally.

    What can go wrong here in this case? Thank you very much for the help.

    Concerning

    John

    OK, I read through the thread and this is my point of view on this based on works including restore process with the user created a recovery (UCRDs) media which the user indicated that they used.

    If you just want to jump to the conclusion at the bottom, you can see my opinion. If you want to know 'why' Please read the entire post.

    Model No.: m7-j010dx

    Product #: E0K83UA #ABA

    Ships OS: Windows 8 (64-bit)

    Recovery HP part No. Kit: 730336-002 (3 DVDs + extra)

    User replaced the HARD drive with a 1 TB hard drive 5400 RPM with HP ProtectSmart hard drive Protection a new hard drive is a Seagate Momentus 7200.4 ST9320423AS 320 GB 7200 RPM 16 MB Cache SATA 3.0 GB / s 2.5 "Notebook internal hard drive.

    With the help of UCRDs sent media recovery media (SSRDs):

    When the UCRDs are created, only the drivers for the HW operation (this is a critical point, that I will look later) are burned to the user created a recovery media.  Consider this a snapshot of the current HW, the base drivers and software applications.   If you change the HW on your laptop or desktop where the additional device requires a different driver for these features, a few questions you might - recovery process could stop because he can't find the right driver, a blue screen, a lack of start-up or other unstable system.

    A few years ago, I had a PC that would not recover because the Blu - ray (ODD) optical disk drive did not work.  I replaced the WEIRD Blu - ray with a generic DVD/CD burner into the new part of Blu - ray is presented.   I got the PC using SSRDs thinking I would put some time and just install the Blu - ray after the PC has been recovered.   The PC recovered and when the new Blu - ray showed I installed the unit and guess what?  All PCs have shown in Device Manager and applications was a generic ODD - no Blu - ray capability and ability to read Blu - ray content in the default HP provided for multimedia applications delivered with the PC.  Applications were there but no Blu - ray capability.

    Huh?  It looks that I did not put any time at all.

    I inserted the new Blu - ray ODD and distributed recovery with the HP SSRDs.

    After recovery, I had all the Blu - ray drivers and applications supported Blu - ray.

    The difference between UCRDs and SSRDs:

    UCRDs provide a glimpse of what is installed and functional both disks are created.

    Version Digest of the player on what is happening with SSRDs to retrieve a PC (before Windows 10):

    SSRDs have all the drivers for all the HW and SW qualified for the unit.  There may be several drivers for hard drives, different types/screen resolutions, sides, etc.  Based on the characteristics of the specific laptop / desktop a process is run called "Do / don't.   After entering the recovery SDRD, the Notebook media boots to Recovery Manager.  The first step is a raw copy of all the contents of the disc on a temporary partition.  Following the Do / do not process looks at the characteristics of this specific unit and remove all other drivers and applications not used by this device.  Drivers and the only successful applications are the features supported.   And then, the new operating system and recovery partition is created.   The PC end recovery of cleaning process and restart the laptop / desktop. And, Yes, you guessed it, if you create the user created a recovery media, you only have the drivers for HW devices and applications of HP on the PC at the time.

    So, that being said, what could be the cause/solution?

    Hard drives can be different enough so that a different driver (not the UCRDs) is necessary for the newly installed HW.

    The SSRDs are supported on the new HARD drive installed?

    I don't know, I have an office boy, and I have not tried on this model of laptop.

    If you have / acquire SSRDs, I recover the laptop with the new installed HARD drive and see if it works.  It may or may not.  I don't know what drives were qualified for this laptop.

    If this does not work, the last option is cloning via USB connection (old HARD drive in the PC, new HARD drive connected to a USB 3 via the SATA Adapter (dongle) USB port, install or download software cloning and cloning the old HDD to the new.)   I just did this on the two older Windows 7 computers laptops using a SanDisk Ultra kit.  He has worked on both units.

    Conclusion:

    I don't think that the problem is caused from a HARD drive of 1 to a 320 GB HARD drive, as it meets the minimum specs for a complete installation.  I think the problem is related to the use of UCRDs to retrieve and the UCRDs do not have the HARD driver/firmware/application disc.

    But then again, I know.

  • VMware SRM 5.8 and EMC RP

    Hi people,

    Thank you!

    Best regards

    Guests of protected sites are restored from sleep mode (DPM is disabled) so that storage can be removed on their part and set to read only.

    I agree with what said GSS, the problem with the LUN downgrade error is very likely with the SRA and that is why EMC. I think as the hosts of the protected site of sleep problem can be linked to that as well (not able to remove LUN?)

    About your VM stopping, you say that the virtual machine stops successfully? The default value is for MRS wait 5 minutes (300 seconds) for closure, if the virtual machine takes more time that you do not want to change the timeout value in the advanced settings.

  • "HP pavilion slimline: problem with the disc of"recovery"would be"

    I just got a Seagate 1 TB drive backup and have backed up my entire computer to him.  My concern is that my "D" drive, the separate part of my computer that contains the disc "recovery", is almost completely full - its presentation as a solid red bar on my screen - only left 320Mo of 11.7 GB - would have this effect, the performance of my computer at all?  Why is it so plenty of anyway and what can do about it?  Problems with my email and its indicating that I am "" out of memory "-well, I've got a lot of memory on my C drive, which is not a problem, but the same effect my email D drive?"  I use Windows LIVE mail incidentally, and I had problems in the past with it, been quite some time however.  Woud grateful for the help with this.  He used to ask me to put in CD on backup drive D with - don't know why, but I immediately my Seagate drive, now, just do not know what I have to do at this point.  Thanks for any help.

    I have no idea why the "D" drive is a solid red bar, nor why it is so full.  I've changed nothing since I bought the computer.  How would I know if something is to use the D drive?  I thought that it was 'partitioned' off so that he couldn't be touched?  I have everything on my laptop hard drive Seagate, and I mean everything.  I also have system recovery disks of mirror image right after I bought the computer, but that does not tell me why that drive D is now completely "full", it should not be.

    I don't know if you have "solved" the problem, but I guess that the D drive is of no consequence right now even if its 'full' and probably shouldn't be.  Maybe my problem is WINDOWS LIVE MAIL, and I maybe need to do another post to see if anyone can help with the next.  Thank you.

  • 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.
