MD3000i down [CF]

• Disorders of MD3000i controller

  Hello

  It seems that my MD3000i continues having controller problems. I get tons of critical errors via email notification, but whenever I'm in MDSM - status is optimal. The error messages I receive refer (for as far as I understand) on two controllers (enclosure 0, slot 0 and enclosure 0, slot 1). It means that both controllers have problems or that this means that a single controller continues to go down (restart) and fall back on the other controller? The errors are:

  -Optimal wide port becomes degraded (event 1706 error code)

  -Wide port degraded becomes impossible (1707)

  I would consider replacing a controller if I can confirm which of the two is a failure. Is there a way to determine which of the two controllers boredom?

  This MD3000i has now reached the end of his LIFE, and we have not supported more...

  Thank you, Alex.

  Hey, Alex.

  After a deeper look in this set, it seems that the raid at location 0 controller seeks to go south on you. You may prepare yourself to get another. We can check it out if you can get your cable from the console, plug it into this controller and capture the output via Putty.

  If you need the Putty settings and how to do this, let me know and I can send the instructions.

  BUT it seems that the controller 0 is continually being reset to the other controller. This usually means a replacement of the controller.

  Edit: I forgot to mention also that the disc into the slot in enclosure 0 10 is on its way. It would be good to replace this one.

  Wish I had better news for you.

• MD3000i and TL 2000

  I was wondering if it is possible to connect the TL2000 to the MD3000i SAS out port.

  TL 2000 has 2 LTO 3 drives with SAS ports.

  The MD 3000i has dual iSCSI controllers

  The reason is that I picked up a used rack. And everything should work, but I did not see the connected cables before he was down.

  And I don't see any other sources he may have been connected. None of the servers have no external SAS port.

  When I plug the 2000 TL in the MD3000i she complains of the degraded SAS ports and it stays that way.

  TL 2000 said its 3/Gbit connected and OK. I read somewhere that degraded port maybe because it is using 1 of 4 channels.

  Both are upgraded to latest firmware.

  So my questions.

  If supported what menu in MDSM would he appear in if everything...

  If not supported what SAS card recommend.

  Thank you

  Kristian

  Kristian_Br,

  You are not able to connect the TL2000 behind a MD3000i. The reason behind this is that the CM in the 3000i is a RAID controller and you cannot connect the TL to a RAID controller. The TL2000 is supported only to work when it is connected behind a 6GB SAS HBA. That SAS Out Port is only intended to connect the tables as a second MD3000 or an MD1000 expansion MD. If you have any questions do not hesitate to let me know.

• MD3000i seems to be only using 1 controller

  We had some problems lately with the disk performance in our VMware cluster. Our facility is:

  • 3 of Dell R610 running ESXi 5.1
  • 2 Juniper with 3 gigabit switches VLAN (1 for management, 2 for iSCSI)
  • 1 double Dell MD3000i controller
  After troubleshooting for awhile, I found that I could use SMcli to monitor the performance of the SAN. After that, the results were a little surprising as it looks like one of our controllers seems to be totally inactive. I took a screenshot of the results: (ignore the name of the storage array. It was previously used in a configuration of XenServer)
  
  My question is, how do I get it to where the two controllers act as a pair for optimal performance. I think there must be a way to have VMware hosts to take the shortest path for each controller to get the disk, is there not?
  Any help would be greatly appreciated that it was me left speechless for awhile and internet research has not received me very far.

  How do you carve up your virtual disks? The MD3k series uses a single controller as the owner of a virtual disk and the other controller is only for this virtual disk failover. That is why several virtual disks running (that spread between 2 controllers) is a better choice on a virtual disk of size unique max.

  Also; the MD3000i is not validated for vSphere 5.x. It's probably not the cause, but it is important to keep in mind if you plan to use it for production (in general, I would recommend not not to run production on this combo (MD3200i upgrade) or down to vSphere 4.1).

  It is also important to use 2 subnets and port 0 on both controllers on a single subnet and port 1 of both controllers in the other subnet. Then, each server should have 1 NIC in each subnet.

• To access ESXi 4 Update 1 custom server from dell MD3000i iSCSI SAN

  Hello

  I'm brand new on VMware ESX/ESXi products and for the most part, no.  I configured several machines virtual with server 1 and 2.  I am trying to connect a virtual ESXi 4 server in a SAN and starts to become very confused about what I can or not do.  I hope that someone here can break it down for me because I couldn't find the answer to my specific questions.

  Here's how I'm Setup:

  I have a Dell PowerEdge R710 with ESXi 4 Update 1 'Custom Dell' (whatever that means) is installed.

  I have a Dell MD3000i SAN using iSCSI with a pre-configured dedicated virtual disk.

  I would like to create virtual machines on virtual disk said.

  I think that ESXi 4 is completely free.

  It seems that to manage the server, I need to use 1 of the 2 products.  The Vsphere client or web application of VMware Go.

  If I use Vsphere:

  I have the ability to add a type of storage through the user interface.

  I'm on a 60-day trial. I thought that it was free.

  If I configure my iSCSI via Vsphere and then the eval expires... what happens?  All jump on me and then I have to purchase a license to get it back?

  If I use VMware go:

  It seems I don't really have any options to do any kind of configuration iSCSI in VMware Go.  I do?

  I also have a XenServer that is configured in this way and it's all free. I wanted to try the bare metal of VMware solution, but now I wonder if I'll have to go back to Xen.

  Can someone please relieve me of my confusion until I have to pull the plug on this experience.  Maybe direct me to the proper documentation on how to configure what I need with what I have at the cost free-is possible.

  Thanks a lot for your comments and have a wonderful weekend!

  I'd go by QuickStart Webcast and Webcast ESXi Webstart to help get a better understanding.

  I spoke with people from Dell and Vmware support.

  Support for VMWare counterpart said that it is a matter of Dell... that VMware is a path problem and do what it is supposed to do.

  The Dell guy says there is nothing wrong with the MD3000i and the problem is with VMWare.

  None of them seem interested in helping me out more.

  I tried using MRU (default) & political pathing Round-Robin and set up iscsi on the host esx, in accordance with the following document:

  http://www.delltechcenter.com/page/VMware ESX4.0andPowerVault MD3000i

  I can vmkping for all the guests of all the peoples on the MD3000i without any problem.

  If someone saw, I would be very grateful.

  Thank you

  Hmmm...  Well, if they are flipping back has nothing to do with VMWare, it is certainly a matter of Dell.  Have you tried their repatriation to the correct drives and then just reboot the stupid thing?

• Date page does not appear first drop the bar down

  Just downloaded the new ios and found that the Notification Center page appears first when you use the new bar drop down. I have to keep pulling down then drag to the right to display date apps, weather, news, etc.

  Please help me solve the problem.

  Hi sangani53,

  Thank you for using communities Support from Apple!

  This message indicating that your iPhone must cool before using the flash indicates that the temperature of your iPhone is passed to where certain features will be disabled.  Once you bring the temperature down, the features should come back.  Take a look at this link for more information on updating your iPhone in the operating temperature.

  Keep the iPhone, iPad and iPod touch in acceptable operating temperatures

  Take care.

• You can drag down to default widgets?

  I just bought a new iPhone with iOS 10 7. On my 5s, I could swipe down from the top of the screen and automatically bring up the widgets where I had time at the top. It was perfect because no matter what I did everything I had to do was shot down and the weather seems. Now when I slip down to the Notifications by default, I rarely, if ever actually used. I then have to drag to the right to open the widgets. Is it possible to ensure that you can drag down to jump to widgets instead of having a blank page of Notifications and then drag to the right? It now takes twice as long to perform the same simple task.

  Hey BKavett,

  I understand that you liked using the view today in iOS 9. The good news is that this feature is still available, but has changed the way to access it. In order to access the view today in iOS 10, slide between the left edge of the home screen or the lock screen. Take a look at this link for more information:

  How to stop these little boxes of new emails coming down on the top right of my macbook air

  Hi Bunt11,

  I understand that you do not want to stop the boxes that appear at the top right of the screen on your MacBook Air (also known as the notifications) when you receive the e-mail. Fortunately, this can be done relatively easily in the system preferences. You can open the system preferences () in the Dock (if she appears at the bottom of your screen), or in the Apple menu > System Preferences. Once you'll want in system preferences, click Notifications, and then click Mail in the list on the left and select "None" rather than "Banners" or "Alerts" on the right.

  Notifications systems of preferences allows you to indicate when you do not want to be disturbed by notifications and set options to control how apps to display notifications and how they are sorted in the Notification Center.

  To open these preferences, choose Apple menu > System Preferences, and then click Notifications. Select do not disturb or an application on the left, then view or change the settings on the right.

  Alert style [app]

  Select a style for notifications from the app: No: Notifications do not appear on the screen. Banners: Notifications are displayed on the screen and disappear after a while. Alerts: Notifications to remain on the screen until that fire you.
