• Reference Dell MD3000i and degraded physical disk channel

  Nice day

  We have a Dell MD 3000i with an extra box storage. And today, there are two mistakes in the journal:

  1 physical disk channel set to gradient

  Date/time: 30.04.13 10:56:14
  Sequence number: 9783
  Type of event: 1209
  Description: Physical disk set to gradient channel
  Specific event codes: 0/0/0
  Event category: error
  Component type: channel
  Location of components: side physical disk: channel 1
  Recorded by: Module to slot 1 RAID controller

  2. each physical disk - gradient path

  Date/time: 30.04.13 10:56:14
  Sequence number: 9784
  Type of event: 1513
  Description: Individual physical disk - gradient path
  Specific event codes: 0/0/0

  Recorded by: Module to slot 1 RAID controller

  In this case recovery guru say "you must contact your technical support representative to correct this defect. Do NOT try to fix this problem yourself. So, how we can receive technical support recommendations and try to repair this failure?

  If you need more details, we can put any storage array profile output.

  Hello UtkinE,

  Yes, you will need to stop all iSCSI traffic so that you can update the NVSRAM.  With the timeout error you get all came from controller 1 & he had only discs 1 & 5.  The current version of NVSRAM you version 4 and the last one which is for the MD3000i is version 13.  With who have older firmware it was improvements to correct your problem in the latest versions of firmware.  I also had one of our analysts will confirm as well just to make sure that it is the best fix for your problem.

  Please let us know if you have any other questions.

• Reference Dell acceptable EQL PS4100xv latency

  Hello

  I had a Dell PS4100xv with 3 three servers connected via 2 x PC6224.

  The total consumption of the IOPS / s does not exceed 600 IOPS / s. Most of the OPS / s time is about 300 IOPS / s. In looking at SAN HQ, OPS are / s taken max supported by the table on the RAID 6 should be about 1500 ms.

  The latency is about 20 to 50 ms.   However it reads about 80 to 100 m, but it is not maintained.

  What is the acceptable latency for the EQL? I have Windows 2008 R2 SP1 and some Linux virtual machines.

  Application performance is acceptable.

  Thank you

  Paul

  OK, that will certainly be delayed ACK and / or LRO.  In addition, should check that MPIO has Round Robin with IOs by path to 3.  (Default for RR, 1000 IOs before moving paths)

  This link is a PDF which covers all the best practices for ESX + EQL.   There are some very important parameters for the performance and redudancy in this guide.

  en.Community.Dell.com/.../20434601.aspx

  The question of priming is probably different from the issue of latency.  Given that very few of IO to the SAN occurs during startup.   If you look at the EQL GUI, you can see the speed at which the connections met.

  I have a laptop Dell Inspiron

  Now, my question is will I be able to save my other files on the external hard drive that I use for the above process?

  (as the above process creates two partitions of 921 GB & 500 MB)

  You will need to copy your other files on the hard disk before the distribution, you will lose it. When you have completed the process you can put back them on here.

• I forgot my password for windows 7 for my laptop and a reset disk has not been created. How can I recover the password or create a new one? and I have a dell desktop inspiron one 19

  I forgot my password for windows 7 for my laptop and a reset disk has not been created. How can I recover the password or create a new one? and I have a dell inspiron one 19 desktop... your help will be very appreciated thanks in advance!

  Here are the usual methods to solve this problem:

  • Restart the computer with your Windows repair CD, then use system restore to set Windows in a few days (only works if you have recently changed the password).
  • Logging in as a different admin account and then reset the password for your existing account (works only if create you an alternative admin account).
  • Log in as administrator mode without failure, then reset the password for your existing account (works only if you have activated the account administrator and know its password).
  • Insert your flash drive USB with the password key file (only works if you have created such a keyfile).
  • Check your paper files (works only if you threw down the password somewhere)

  If none of these standard precautions work for you, then the remedy will be painful. Post again if this is the case.

• Live iSCSI SAN upgrade production network (Dell MD3000i and PowerConnect & ESXi 4)

  Hi all

  For the moment, I have a direct connection to my Dell MD3000i iSCSI SAN in ESXi 4 2 x host with no switch between the two, all of the virtual machine is within the SAN and running on both hosts.

  If I want to put a switch between the two and add one more iSCSI SAN so that the two SAN can be accessed / shared with the 3 ESXi 4 guests total, how should I approach the issue?

  any idea or guideline would be greatly appreciated.

  What I have to plan the time or can I change the old IP on the existing SAN iSCSI manually cable one by one without damage/alter the existing operation of the virtual machine on SAN? or I have to stop the virtual machine and then terminate the connection manually iSCSI session and then restart the host SAN?

  Thank you

  AWT

  Standard installation on the MD3000i is for a port iSCSI on each controller on a subnet and one on each controller to be on another.

  There have been people working successfully on a subnet, reported problems too.   I wish we were longer on our Vsphere upgrade, I'm not at a point but where I test things like Vmotion.

• computer windows XP won't load does not and cannot get disk recoevery to run

  After turning on my computer comes up with the Dell logo and then turns off. I tried to start in safe mode and thus to an earlier point, but nothing happens, and the processor is very quiet, so maybe it's that. My main problem is how to get all my files and folders from the hard drive...

  Hi carelesstalk,

  1. don't you make changes before the show?

  Try these steps and check the result.
  Step 1: Start the computer using the 'Enable VGA '.
  a. see the Description of the Mode of course in Windows XP startup options
  b. in the safe mode options, select "Activate the VGA Mode" and check if the computer starts.

  Step 2: If you are able to run the computer to activate the VGA Mode, then turn off the graphics card and check if the computer starts in normal mode. To do this, try the following steps:
  a. Click Start, click Run, type devmgmt.msc, and then click ok.
  b. expand display adapters, right-click on the sub element and click on disable.
  c. start the computer and check if the computer starts.

  Note: If the computer starts in normal mode, and then uninstall the video card.

  Step 3: If nothing works, then perform the repair facility using XP disk and check the result. To do this, try the following steps:
  a. start the computer using the XP CD. You may need to change the boot order in the BIOS OF THE system for the CD starts before the hard drive.
  b. on the "Welcome" screen, press ENTER to start the installation of Windows.
  c. accept the license agreement and Windows will search for existing installations of Windows.
  d. Select the XP installation you want to repair in the list, press R to start the repair.
  e. the installation program copies the necessary files to the hard disk and restart.  Do not press any key to boot from CD when the message appears. Setup will continue as if it were a clean install, but your applications and settings are preserved.
  f. when the installation is complete, check if Windows starts correctly.

  If the problem persists and you are using a desktop computer, we you recommend removing the hard drive and connect it to another computer and then back up your data.

  For further assistance, please contact Dell support.

• Issue backup - SAN/SAS/Disk-to-Disk

  We are currently planning to introduce the VMware with a Dell SAS connected SAN and a couple of physical hosts. A separate physical host is expected to run only with no installed VMware backups, there a SAS card is connected to the San and the backup tape device.

  The backup application will be CA Arcserve. With this situation, that we will be able to backup individual files/folder on each virtual computer via integration with VMware? What part of VMware would need to be installed on the backup server to enable this? A separate physical host was chosen so that a disk to disk-to-tape strategy could be used to reduce the backup window.

  Is there a better method?

  CA Arcserve must be installed on a virtual machine instead?

  what you look at is vstorage APIs for data protection. You can read more here, and also you will need reach CA on how to activate and work. http://KB.VMware.com/kb/1021175

  Start the computer in safe mode (press F8 continuously immediately after power and don't worry beeps when you press the button) and let it boot without a network.  Once there right click on the desktop and then click Properties.  Click settings and the value of the monitor mode (640 X 480) VGA or SVGA (800 X 600).  Accept the changes and restart the computer.  You should have a mediocre screen, but you should see it now.  Download and install the appropriate drivers for your video card in the laptop to the web site of the manufacturer of the laptop.  Install the drivers and then you should be able to set the display of the laptop to the correct native resolution for your computer monitor (must be in the documentation of the laptop).

• New Dell ships with no. install disks

  My new 8900 XPS came with pre-installed W7SP1, more a disc of 'upgrade' to W10 (like that will happen) (until they do a XP style extortion, in other words). Given that MS has rendered impassable to XP, and
  Vista and 8 were written to destroy productivity and modern trade, I intend to stay on 7.

  So I have no OS install discs, no keys etc, produced for the operating system, I'll be with for a long time. I ran the recovery of the factory, so I did that at least. Still get installation disks?

  However, I also used Clonezilla to create an image of my entire hard drive. From scratch means many hours wasted installation of software. I don't want to have to do it.

• Reference Dell backup and restore is unable to create a DVD of recovery on Windows 8

  Dear Dell,

  I am creating recovery discs "Dell backup and Recovery application" but when I was asked to insert the second DVD, the optical drive keeps rejecting DVD. The application will not continue to burn the second DVD and seems to be frozen. I tyied with different DVD brands/manufacturers and also-/ + r unfortunately. The question remains. I could find this 593906 article published 21-01 - 2013 (http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&cs=19&docid=593906&doclang=en&l=en&s=dhs link). Although I did the updates, I'm still not able to create recovery discs!   File: after having inserted the Disc 3 application gives the message "Dbr.exe-" not found disk and stays there and rejects the DVD.  I spoke with the Greek team of Dell. I was told that warranty does not cover the support of sw even if my unit is less than a week. Furthermore, I learned that although "Dell backup and restore" application said THAT DELL is not actually a Dell product so they can't support. They my proposed to use the recovery of files from windows 7 place (which needs at least 8 DVD!). As you can understand it's a workaround and not a Solution.

  I hope that someone from Dell will consider the issue and to come back with a precise answer and a permanent solution.   (Model: inspiron 15 3521). Thank you

  Hi ylikonomos,

  You can try to uninstall and reinstall Dell Backup and Recovery Manager and Dell Support Center. Follow these steps:

  • Press the Windows key + 'X' on the keyboard.
  • Select "Programs and features" in the context menu that appears in the lower left corner.

  

  • In the list of applications, uninstall Dell Backup and Recovery Manager and Dell Support Center.

  Below, check the version of the BIOS installed on the laptop. Press Windows + "R" key, type msinfo32 and press ENTER.

  

  

  Identify the version of the BIOS. If A04, the update of the BIOS is not necessary. If this isn't the case, update the BIOS. Before flashing the BIOS please check this following:
  * No external device (printer, USB stick, SD card, DVD) must be connected.
  * All other programs should be closed and saved documents.
  * The power adapter and the battery must be connected during this process. The battery must be 10% or more than 10% of charge.

  Here is the link for the update to the BIOS: http://dell.to/VBwSAh. The laptop restarts after this update.

  Visit this link: http://dell.to/VBz1fr and click Dell Support Center. Download and install the application.
  Once done, visit this link: http://bit.ly/UUjIs0 and install Dell Backup and Recovery Manager. Restart the computer and check if you are able to create the recovery media.

  Please, try the following steps and share status.

• Reference Dell backup and restore - "an error occurred during the creation of the backup of the system"

  I have a Dell XPS-8700 running Windows 7.  I bought the Dell Backup and Recovery Premium Edition.

  I was able to create a backup bootable (hot spare), and I can create a backup of data on my external hard drive.  However, whenever I try to create a backup on my external hard drive system, after about three seconds in the process, he returned: "an error occurred during the creation of the backup of the system.

  How can I create a backup of the system?  Why I get this error?

  Thanks for all the info. My situation sounds very similar to yours.

  I removed using Add/REMOVE programs in the control panel DBR and he removed cleanly.

  V1.7.1.2 downloaded and executed new facility.

  When I ran, it was my premium license key so he had yet to register and was not removed by uninstall.

  As before, Rescue Disk ran and installed the new partition (DBR_BOOT) on WD Passport.

  However, backup system immediately stopped with disconnected, missing target location or full. Tried several times...

  In any case, sounds like you have solved your problem, so you like OP should this brand this post/thread as answered. I will continue to post on my other thread.

• Problem with the Dell recovery and backup system

  Hello

  I have problem with dell backup and restore in my dell laptop (inspiron15). When I select the backup factory option > choose a drive then continues, he said 'Please sustained insert blank to keep media. "
  However, blank disc is already inserted and formatted with the live file system. Please help if anyone has the solution.

  Thank you

  Hello

  Thanks for your reply.

  Usually, the blank DVDs would be already formatted and ready to use as they are writing discs once. Please try to create the backup disk without formatting the DVD.
