• Collision of signature on second SATA Drive - Win7

  I have 2 identical Dell XPS410s running Windows 7.  The motherboard on a death.  I want to recover the data on it, so I installed the hard drive of the PC dead my XPS410 (SATA 2 port) in the other.  The BIOS sees the drive Win7 Explorer cannot.  When I look at the drive in disk management in the Microsoft Management Console is the new drive to be offline make a collision of signature with my original hard drive appears.  How can I fix?

• replaced RAID controller - new signature or use existing assignment request

  Hello

  Recently, I replaced a problematic to find RAID controller that the virtual drives are not mounted automatically by VMWare after a reboot.  I guess it's because when I add data warehouses, I wonder to use the existing disk signature or to assign a new signature.  At the beginning, I chose to use the existing one.  If I chose to create a new signature, this will solve my problem of mounting disks does not automatically?  If so, my BONES existing comments will be tactful or they might have problems?

  Resignaturing a data store should not harm the data on this subject. However, after resignaturing you can see all the VMS in the inventory as inaccessible and need to remove the inventory and add their .vmx files in the data store Navigator right click. What you can try is to manually mount persistently store data from the command line to see if that solves the problem without resignaturing (see http://kb.vmware.com/kb/1011387).

• Convert a RAID non RAID?

  I have a Dell computer with two 1 TB drives in a RAID array.  I would like to convert these disks in a regular table non-raid. How can I go about it?  In the BIOS, I see that the sata is configured for RAID, but I don't want change there without knowing what else this way.

  Thank you!

  John

  Thank you both for the quick responses!  Thanks to a Dell support conversation, I broke the RAID1 array in two standalone players (control - I have started and then 'delete Raid Array' I can now see the second unit of disk in Windows, at startup, etc., but the Configuration of Windows disk utility does not create volumes.)  He says he has a "signature conflict."  Is there a way I can format this disk section?

  Thank you!

• HP Pavilion dv 6000 (GB113AV): full (D) recovery partition

  After having looked up how to change the value of the partitions, I learned that it is not possible for me to extend the recovery (D) partition using windows.  It is full with only 444 MB of 7.15 GB free space.  Is it possible to extend this partition.  I have a lot left of the room on the C: partition.  If this isn't the case, it would be possible to replace the HARD drive with a larger capacity and a larger D: partition?  I know I have to replace all the files on the existing HARD drive.  The installed HARD drive is a Toshiba 1237GSX ATA Device.  I know there are questions of compatibility of the bios in lieu of a HARD drive.  Thanks for any help you can give me.

  You cannot increase the recovery partition, it has the value of the factory. You can replace it with a bigger HARD drive, but you must make recovery disc before you do so that the path, you can use these discs to restore your factory install on the new larger HARD drive. I don't think you can increase the size of the D: without causing any problem since that is defined as a recovery partition and you shouldn't be messing with it. All I know is not something on the HARD disk in conflict with the bios...

• Not able to instant editing on hyper-v cluster volume

  I have a new installation of a 6110xs and a cluster of hyper-v 3 knots 2012.  I have tested and have not been able to mount a snapshot to one of the servers to copy data out of.  I am able to make the snapshot of the Bay of equalogic, see the snapshot to the iSCSi initiator and I also see the volume in disk management.  Disk management sees the volume but it is reserved and I can not put online as it is said that it is managed by the Failover Cluster component.  When I go in the failover cluster manager, it is not the volume (snapshot).

  I found a few other posts on this topic but no resolution. Any help is appreciated.

  Thank you

  Scott

  I would say you have 2 ways to go about this:

  1. use ASM to create snapshots and restore from them. ASM can make complete snapshots of individual virtual machines or CSVs and also to do all things necessary to restore. Functionality for server 2012 are much better for 2008R2, BTW.

  2. If you need / want to do manually, this article will help you: blogs.msdn.com/.../10169759.aspx

• Cannot create instant when quieced cbt enabled on Windows server vm

  Hello

  yesterday I updated my ESXi 5.5 to 6.0 test environment and now I got the problem that my backup software cannot create a snapshot. So I tested and same trough VCenter can't cerate a snapshot of the quieced. I got this error message:

  Fehler beim Speichern Snapshots: msg.snapshot.error - QUIESCINGERROR.

  In the vmware.log I read a lot of mistakes, here are a few:

  Could not open the file change tracking "/ vmfs/volumes/54aea31d-61d81d56-35f9-000423ba9740/srv01-Domaincontroller/srv01-Domaincontroller-000002 - ctk.vmdk ': invalid followed change or drive in use.

  Node 19095c-cbt cbt creation failed with the error can't allocate memory (0xbad0014, out of memory).

  Could not set vmkernel change Tracker: monitoring ESXi filter failed (0x143c). Drive will be open, but follow up information changes vill be invalidated.

  Could not repair the disk signature writable snapshot 'scsi0:1 '.

  Snapshot 62 failed: impossible to suspend the virtual machine (31).

  When I stop the virtual machine, remove the ctk files and modify the configuratoin of the virtual machine for:

  ctkEnabled = true (or false)

  scsi0:1.ctkEnabled = false
  scsi0:2.ctkEnabled = false

  Then I can do an instant downturn. The false to the scsi0:x is important. When I switch back the configuration I can't do an instant downturn again.

  This is the case the following OS:

  Windows Server 2008 R2

  Windows Server 2012

  R2 Windows Server 2012

  I can also cerate a snapshot of slowing to a virtual Windows 8.1 without problem computer and a Linux VM.

  I have already created a case at VMware, but the defender was looking a bit, gave me a tip that does not work and told me that there nothing more, he can do it, because my Supermicro motherboard is not on the supported list.

  This I don't understand, we are a partner of Enterprice of VMware, I want to test the new version in my test environment before I install this at a client. Now, I had a problem, and it seems that VMware will not help me because the motherboard is not ' t supported! But this is not like a hardware issue to me.

  Here is maybe someone who has the same problem or can made a test what happens when you turn on the cbt for a virtual machine.

  Kind regards

  Re: Compress all the existing table ain dat

  So I would say the same thing, that I suggested it with minor changes.

  You give us your preferred solution instead of us giving that information about the PROBLEM you're trying to solve.

  You must first focus on the problem:

  1. define the problem - indicate the desired objectives
  2. identify the options and resources available to address the problem
  3. Select one or several small, these options for assessment earn and tests.
  4 testing of possible solutions
  5. Select and implement what you consider the "best" solution
  6. monitor the results
  >

  Why? 1. What is the problem that you are trying to address and what are your desired goals? Partitioning is a solution - what's the problem?
  >

  >
  Great! Do you really need or even want options housekeeping? If so, which? Don't you bulk loads? Down periodically the data? How many times? Monthly? Every year?

  What is the relationship, in your analysis between partitioning and your reports running "as fast as possible? Give us some details. Why do you partitioning in general (range or range-hash in particular) will somehow make your reports run faster? What kind of reports? The amount of data they have access to produce? The amount of data returned in fact? How many times reports do work? How much of a problem reports are now? Generally meet their SLA? Or they RARELY meet their SLA?

  Partitioning is not a remedy of performance for badly written queries. Often the most effective way to improve the performance of reports is to resolve any issues the queries themselves may have or add appropriate indexes. You have exhausted these possibilities? Have you created and examined the execution plans for your key reports? That shows this analysis?

  For a partitioned table, all data are stored in individual segments; a segment for each partition.

  For a partitioned table Sub all data are stored in the individual segments; a segment for each subpartition. There is NO data stored at the partition level.

  The type of partitioning (versus range-hash hash) and the type of data (partition versus subpartion) logic has no relevance in terms of performance.

  Performance of the queries are directly proportional the number of segments that should be available, the type of access (via the index or full scan) and the size of the segment (including the amount of data).

  The number of segments that should be available depends on the ability of the Oracle to prune partitions during the analysis statically or dynamically at run time.

  Partitioning then generally won't be valuable performance but only for maintenance operations.

  Please explain why you think that partitioning will provide this benefit.

  Oracle PARALLEL query very well on non-partitioned tables without using partition-wise joins. The latest version of Oracle also has a DBMS_PARALLEL_EXECUTE package that provides additional features for the realization of PARALLEL operations for many of the use cases more.

  Partitioning lends itself to a natural method of CHUNKing based on the scores/subparts, but that is not necessary to get the benefit of the PARALLEL use. The exception would be if provided partitioning segments that are on different axes or decrease disk IO conflicts.

  Another missing piece of key information are the number and the type of index that needs your reports. Will you be able to use mainly LOCAL partitioned indexes? Global index tend to destroy any maintenance performance that can be learned from partitioning.

• Signatures - inconsistencies/conflicts

  After digging through the definitions of standard signature, I came across some inconsistencies and errors-possible.  Should I open a TAC case to eliminate them?  A few posts in this forum?  Or y at - it another way to have these questions?

  For example...

  - 0-3308/GIS is a component of the meta-signature 3338/1

  -GIS-3308/0 is made obsolete by GIS 5580/0

  - GIS-3308/0 is always enabled and not retired by default, even if it is obsolete

  -GIS-3338/1 references still 3308/0 as a component and does not reference GIS 5580/0 to all the

  This just isn't for me.  Shouldn't 3308/0 being disabled/retired by default?  Shouldn't 3338/1 being reference 5580/0 as a component upgrade?

• Dual Boot with windows XP Pro with 2 HARD drive, error on secondary windows install: "Windows did not start because of a configuration of the disk of the computer problem. Could not read the selected boot disk. Check boot path and disk hardware... »

  Hi, I recently bought a new Hitachi 1 TB internal hard drive. I wanted to do a clean install on the new drive (d), be able to dual boot my computer and leave my old 300 GB disk (C :) as the primary windows installation. After physically installing the new HARD drive, I noticed that "new hardware found" and the the brand name flashed in the bottom right corner. I thought I'd see the new hard drive in my computer, but I did not. I initialized the new HARD drive with the computer management window (right click on my computer - manage) and I also formatted in NTFS (I had to change my printer hard drive letter to assign the new HARD drive with the letter D, but I've made other changes after this step). Now, I could see and use in my main windows on the C: installation. I then installed a windows new copy XP pro with the installation CD I got for my C: but on the D: (Note: I have a Dell computer (and the Dell reinstallation CD) and my current version of windows has SP3 while the installation CD is only SP2) (I also reformatted my HARD drive during the installation of windows to NTFS)

  Now when I try to start on installing the new on my D: I get "Windows did not start because of a configuration of the disk of the computer problem. Could not read the selected boot disk. Check startup disk and hardware access path. "and another line saying to refer to manuals HARD drive and windows.

  My Boot.ini file at this time was:

  [boot loader]
  Timeout = 5
  default = multi (0) disk (0) rdisk (0) partition (2) \WINDOWS
  [operating systems]
  "multi (0) disk (0) rdisk (0) partition (2) \WINDOWS="Microsoft Windows XP Professional "/ noexecute = optin/fastdetect
  "signature (ac516a5c) disk (0) rdisk (0) partition (1) \WINDOWS="Microsoft Windows XP Professional own "/ noexecute = optin/fastdetect

  I looked towards the top of this help page, but for now I'm unlucky:

  http://support.Microsoft.com/kb/314477

  (The next steps I took by throwing from the Windows CD and go into the repair console)

  I tried to use the bootcfg /rebuild but the line to boot.ini for my secondary HARD drive still does not work.

  He gave me something like:

  [boot loader]
  Timeout = 5
  default = multi (0) disk (0) rdisk (0) partition (2) \WINDOWS
  [operating systems]
  "multi (0) disk (0) rdisk (0) partition (2) \WINDOWS="Microsoft Windows XP Professional "/ noexecute = optin/fastdetect
  "signature (ac516a5c) disk (0) rdisk (1) partition (1) \WINDOWS="Microsoft Windows XP Professional own "/ noexecute = optin/fastdetect

  I also tried to change the signature() to multi (0), but it did not work. (or try almost all possible permutations of disk() and rdisk() partition() 0 to 2).

  I also tried to use expand F(dvd-drive):\i386\ntkrnlmp(I_have_a_duo-core).ex_ D:\windows\system32\ntoskrnl.exe and a few other combinations, but I when I login as D:\windows simply, it fails to extend with a message like "could not develop" or C:\windows I get "restricted access".

  I have not yet tried CHKDSK/r, but since I did a clean install on a newly formatted drive... I don't think it would work.

  I've also marked the partition on the D: as active (in computer management), but it did not help me.

  I've done a first installation of windows repair, strangely, I couldn't fix this one... Still does not work...

  My default windows installation yet works very well & I see that windows has been installed on the D: but I'm ideas from how to operate the dual-boot, can someone throw me a BONE on what to do?

  Maybe try to do something with the Boot Manager (whatever it is?) Create a new partition and use it as a boot manager? I don't really want to do this, because if I made a mistake I will be unable to use my computer and dual boot should work without going through all this trouble... But I found this page: http://technet.microsoft.com/fr-fr/library/ee829686%28WS.10%29.aspx

  Could a clean install two HDD help? I hope I won't have to do...

  Someone has an idea?

  PS: I'm not such an advanced user so I need a solution step by step, thanks!

  Edit: I also noted that I can't see my new HARD drive in my BIOS... weird... SATA-0 is my old drive HARD 1 and 2 are my dvd 3-5 readers are 'off' and it doesn't seem to be anything that it is plugged in. I also have 4 bays for internal HARD disks. Now, 2 are busy.

  Edit2: I looked inside my case and enabled the good Sata in the Bios after a reboot it detected the drive correctly. Dual boot doesn't always work well... The fact that it was disable in the BIOS while I was installing the new HARD drive could change anything? Hmm...

  In case I wasn't clear enough: I had a windows XP Pro installed on my C:, bought a new hard drive and installed the same copy of windows on it (d). I think that should allow me to double boot between the two installs different. Even if for some reason I can't boot from one on my D:. Andrew, I do not understand why you so far physically disconnect the other drive, the point of the whole operation is to build a boot.ini file so that the BIOS knows that it y facilities 2 windows and you allow to choose (and not have conflicting problems between the 2 systems), someone correct me if I'm wrong? "Expand" the part of my first post made reference to one of the solutions provided by Microsoft in the first link that I have included in my previous post (but I can't seem to work).

  In addition, it is the procedure that I followed: http://www.ehow.com/how_5950826_boot-two-different-hard-drives.html

  (except I've had the first installation already done).

  Andrew "also, once a new hd is plugged on the pc & running, most of the BIOS will place (them) as 1st priority hd, set the BIOS to do this", you mean that by installing separately from windows on each unit when the other is not plugged in, I could choose what disk to start from defining their priority in the BIOS once they are all plugged back? It's too tedious (as I intend to move frequently between the 2 installs) and requires a computer to other users of the lack of computer knowledge. Unfortunately, it is not a viable option.

  EDIT: I DID IT! Hmmm... Well, I double checked in the recovery console, the path of the new HARD drive with the arc command Scan. Tried to start again with the MULTI (0) in my boot.ini and it worked... I also had my windows install CD in. Maybe that is why I could not start, windows needs the CD to complete the installation? Weird, I don't know what I did to the difficulty it... but hey, it works! Thanks for your ideas guys!

  Here are the results of my Terminal for what you asked in the other threads.

  Can I save my Windows partition or do I have to start all over again?

  Please after the release of

  sudo dd if = / dev/rdisk0s5 account = 1 2 >/dev/null | hexdump - C

• Installation of macOS Sierra results in the error message "load installer has no signature verification.

  I tried to do a clean install of Sierra several times and each time Setup reaches the end and then displays the message "the responsibility of the installer has no signature verification. This leaves the computer without a bootable Mac OS version.

  I tried to recreate the USB key with a new download installer.

  The first Apple support guy that I talked to said to make a recovery of the internet. The problem here is tries to install El Capitan, but never finished. The countdown reaches 0, then goes up to about 30 minutes back. It just keeps doing hours and hours.

  The second Apple support guy that I talked to said to do a regular restore (CMD + R), but it always goes to the recovery of the internet. I'm guessing that there is no restore partition.

  The computer has 10 Windows installed on a Bootcamp partition, and that seems to work very well. I can't installed macOS.

  The computer is a mid-2015 15 "MacBook Pro. I use the disk utility installation program to format the Macintosh HD partition. I used the El Capitan terminal Installer set the hour correct system. I tried to install using another USB port.

  I would appreciate help.
