SRM - excluding the OS data replication store

• 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.

• 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?

• DTS moves to the same data store

  Greetings,

  We are short v5.5u1 esxi and vcenter device with DTS clusters installation using thresholds to space only at this time. We do not limit our VM to place records on the same data and store, and in view of the virtual machine can have his records scattered across data warehouses in a cluster of the DS.

  We have many events that seem to do nothing is represented below.  Everyone agrees that something actually happens or vcenter turns his wheels?

  

  Thank you

  Ron

  Just answered my own question... it has to do with my scattered placement of vmdk. Since the vmx file lives on a given data store, the event shows that the activity... However if you check the DTS tab for the cluster data store you will find the disks associated with the virtual machine on other data warehouses were actually moved.

  

• Question about the replica data store

  I am set up a plan view and I can't find anything on the lines how much I should put on a data store. We have a pretty small environment with approximately 120 related clones.

  Can I create pools of 5 to 10 for all use the same data replica store? I don't want to have all these little datastore who chew on the SAN iSCSI connections. It would be easier to have a data store that is easy to move all replicas.

  Thank you.

  Yes, you can store several replicas to a data store.  It is often considered to be best practices in order to unload the aftershocks of a SSD data store.    I just would make sure that the data store can handle IO reading for all replicas.

• Reconfigured HP Data Replication Group does not present as a group of SRM data store

  Hello

  I configured in two data centers with an EVA4000 on the source site and an EVA4400 on the destination site, countered with Continuous Access EVA of SRM.

  I had replicated two EVA virtual disks (and ESX data warehouses) on the EVA4000 Source called EXCHANGE01 and EXCHANGE02 that have been configured in separate groups, data replication (named EXCHANGE01-GROUP and EXCHANGE02 GROUP) of the HP Command View EVA. These have been picked up properly by SRM as replicated data stores.

  So I decided that it would be preferable to not not two data stores more as a single unit and therefore re-configured continued access by removing the virtual disk EXCHANGE02 of its data replication group and adding as a member of a GROUP named EXCHANGE01. After that, the GROUP named EXCHANGE01 is fail-over for Command View EVA unit and contains EXCHANGE01 to virtual disks and EXCHANGE02. The problem is that when I use the "Rescan replicated storage" option in SRM, you can still see the two Datastores EXCHANGE01 and EXCHANGE02. As it is, I need to create two groups, one by the data store, while in reality a continuous access switch the two as a single unit. The MRS server has been restarted, the berries reread several times, and in fact the EVA4000 has been restarted.

  Two things, I guess. Am I right in thinking that SRM should report to the Group of data replication HP (despite the fact that he refers to it as a\ group data store)? If I am, is there a way I can fix it (preference to short to remove all the replication groups in Command View EVA, a new analysis in the MRS and re - duplicate records?

  I have attached two screenshots - one to SRM showing the list of groups of data store after a new analysis and the other from Command View EVA, showing the Group of data recovery

  Hi Bob.

  The term SRM data store group is intentionally generic because MRS. support many different providers, and all could use a term "Replication group" as EVA does. If MRS. may correspond to a data store that was created on a LUN that the one being replicated is returned by the adapter, it considers that the store of data as being replicated. It's the storage provider for code adapter for return information LUN appropriate to their table - if you look at the SRM newspapers you will see EVA adapter returns each LUN replicated individually with no information about the relationship of Group of replication at all, so it would be impossible for SRM to have knowledge of this relationship as well.

  Although the LUN in a replication failover as one group power group, they can be taken individually for use during the test of SRM, so maybe it's one of the reasons why HP choice to list each ONE separately.

  In all cases, you have several alternatives: one is to keep your existing environment and configure two groups of protection; on the side of recovery, you can set up a restoration plan unique to switch both of these groups; In addition, you may have configured 2 other recovery plans, one for each protection group, which would be only used for the test, and which would test each LUN and virtual machines on it individually - this could reduce the load on the DR ESX servers during the test rather than to test simultaneously. Of course, you can create a single LUN as well and that of course would make the theoretical discussion - it could be better if your virtual machines must be tested together because the application dependencies.

  You might consider following up with HP if you want more insight as to the relationship of EVA "Replication groups" viz SRM, which is why they chose to not to expose information to the replication group.

• Disconnect from the storage data store

  We have two datacenters (Server Vcenter linked mode) - A & B

  Site servers A and B are replicated via san (at the end of storage no SRM)

  Note - what is the known issue in environmental - issues of SAN - every day there are stores in the event of disconnection from the storage data. (Question is 4 months old now). in the Windows Server performance issues.

  For the recommended HP fix update the firmwares of controller on both sites (3 HP EVA controllers) which has been successfully complete however problem has not been resolved.

  There are a lot of outages caused by the problem of storage in the environment. As an example under Server is unresponsive due to the store being disconnected from data storage.

  

  Vmkernal newspapers indicates that it will fail on the physical path

  

  Note storage array - is active active and political path for host ESX is alternating

  What measures can be taken to correct the problem?

  Thank you

  Deepak Negi

  VCP4, VCP5

  What about port enc on connected to EVA in SAN switches? You have CRC errors and if so, whether the counter has increased? Reset the counter if necessary so that you can monitor it.

  What, EVA connect? Any excessive number of links and housing check the errors of State?

• Trend of the report data store capacity

  I am trying to create a table that will mimic what is the report of countenance of canned data store.  I don't know what settings to select.  I know its used space, the total space, hours to full and weekly rates of growth.  I tried using the averages of the period, or period min or max period, I tried current average, current min and max current.  No combination seems to spit on the same results the report canned.  the reason why I need to do this is that my manager doesn't want a 90-page report when we can adapt it on as pages 8 and 9 using a table.  I tried to export the report using excel, but the format it uses is not good and it makes them bounce like 4000 lines.  Please help with the design of report.

  While calculating dynamic, focused on the function of these settings exclude the possibility to reproduce this report as a table using drag / drop, it is certainly possible to build this tabular report using WCF.

  Kind regards

• Good way to use the concurrent data store

  Hello

  I'm developing a multithreaded C++ application that uses the C++ of Berkeley DB Library.

  In my case, I have several databases that I composed in a wooded area. It is important for me to use an environment because I need control over the cachesize parameter.

  I don't need no guarantee of transaction and have for most of the readings, so I decided to use the "simultaneous database.

  I first pre-fill all databases with a number of entries (configuration single-threaded phase) and then work on it at the same time (for most readings, but also insertions and deletions).

  I tried all kinds of different configurations, but I can't work without specifying DB_THREAD as a flag of the environment.

  I don't want to because then access all handles is synchronized sequentially according to the documentation:

  "... Note that the activation of this indicator will serialize calls to DB using the handle between the threads. If

  simultaneous scaling is important for your application, we recommend handles separate for each thread opening

  (and do not specify this indicator), rather than share handles between threads. "

  (Berkeley DB QAnywhere C++)

  So I tried to open the environment with the following indicators:

  DB_CREATE | DB_PRIVATE | DB_INIT_MPOOL | DB_INIT_CDB

  All data in this environment handles are open only with the DB_CREATE flag.

  So, since my understanding this same basic access handles need to be synchronized, I opened separate handles foreach database for each thread (opening the handles is still single-threaded).

  In my first approach, I have only made use of the object of global environment. Which does not work and gives the following during operations error message:

  DB_LOCK-> lock_put: Lock is no longer valid

  So I thought, since the same handle global env is passed to all handles separate DB, it is perhaps a race condition critical on the handful of approx.

  So in my next test, I opened also handles separate EPS in each thread (and db handles owned each).

  That does not produce an error in db, but now it seems that each thread sees its own version of the databases (I call it stat early in the life of each thread and he sees all of the empty dbs).

  What is the right way to use the concurrent data store? Each thread should really open his own set of db handles? What about the number of open handles env?

  PS: Without specifying that the DB_PRIVATE flag seems to do the job, but for performance reasons, I want all operations to perform in the cache and do not specify product DB_PRIVATE average of several writes to the disk for my scenario.

  Thanks a lot for your help.

  CD (simultaneous database) allows a single editor with multiple drives, access to the db at a given point in time.    The handle for the writer doesn't have to be shared with readers.   If you share the DB handle then calls are synchronized, but if each thread has its own handle DB then this is not the case.     Since you have an environment, DB_THREAD must be at the level of the environment.   This will allow the sharing of the environment handle.     This type of error "DB_LOCK-> lock_put: Lock is no longer valid" you can provide us your code so we can take a look.   Also what BDB version are you using?

• Unable to store the component "time" in the column date Oracle's ADF

  Hi friends,

  I have a table with the date column. I'm trying to set the current date with the time in the column of the table. Java.sql.Date refers to the field of the VO. When I try to turn it using the setLastUpdatedDate() it not be saved. The time is get truncated and the time is saved is 16-mar-2015 00:00:00.  How can I keep the component "hour" as well in the column with the date data type. FYI the component "hour" is saved when I do the sql uisng the insert.

  JDev version is 11.1.1.7.0

  Thank you

  Hello

  java.sql.Dateis the DATE of SQL which means it stores years, months and days whilehour, minute, second and millisecond are ignored. Also sql.Date is not related to time zones.

  java.sql.Timestampcorresponds to the SQL TIMESTAMP, which is the exact nanosecond (Note that util.Date only supported milliseconds!) with customizable precision.

• Move-VM error: VM must be managed by the same VI servers as the destination data store

  I work with 2 ESXi servers and a single vCenter server with vSphere 6.0 Update 1 b; and PowerCLI 6.0 Release 2

  I have an a datacenter, cluster, vCenter and a vDS.  I need to pass the vCenter data store to another and get the error message:

  "Move-VM VM you are moving should be handled by the same server of VI as the destination container and the data store.

  Code looks like the following:

  $vctObj = to connect-viserver $vctIPaddress

  $esx1Obj = to connect-viserver $esx1IPaddress

  $esx2Obj = to connect-viserver $esx2IPaddress

  $vmObj = get-vm-name $vmname - Server $vctObj

  $destDSobj = get-datastore-name $destDSname

  Move-vm - vm $vmObj Datastore - $destDSobj - 'End' DiskStorageFormat

  I can migrate successfully from the virtual machine to vCenter data store through the VI Client, but PowerCLI left me speechless.

• remove the Cluster data store data store

  Do you want the LUN to use for purpose of non-vSphere? If so, you can just storage vMotion virtual machines since associated LUN data warehouses that you want to decommission (or simply putting the data store in maintenance mode, in this way, that the virtual machines will automatically be migrated).
