Storage issue: RDM

I have 3 file servers which don't do much besides host shared volumes NTFS (large). I want to virtualize servers said but I have problems with one of the components are how to get their existing LUN in my ESX environment without copying all 3TBs in vmfs. Storage for my environment of vmfs-based (expensive) FC disks and storage for my file systems is based on less expensive SATA drives (virtualized and not presented as SATA drives). This is where that comes RDM to play? I can map these LUNS to the ESX host as RDM files and preserve their NTFS volumes?

No problems.  By default, Windows 2000 doesn't have a driver for FREE.  Free is the fastest scsi controller, but I wouldn't bother with windows 2000, unless you have a lot of them.  For windows 2003, I would use the free.  This can be changed later, but it is more difficult to change on the fly for windows 2000, it tends to a blue screen.  Windows 2003, you can change as needed.

Whatever it is, scsi controllers will operate, free is faster that the BusLogic alire be your preferred to use type.  You can map drives to 14, by controller and up to 4 controllers, so you can have a lot many readers.

  • Storage vmotion RDM

    I tried to storage servers vmotioned 3 which contained a RDM. The RDM were in virtual compatibility mode. I've migrated 2 servers that have been turned off and all was fine until I tried the 3rd server which was powered and it reported an error saying that the block size was too small for the size of the disk.

    I thought that when a server with RDM was vmotioned storage only the file pointer was actually moved and the RDM remained in its orgional State. It seems that the 2 servers I have storage vmotioned now have virtual disks and the RDM were loosened. I've not turned the servers still to see if the data is still there as I don't know what the status of the servers were before the storage vmotion as they have been turned off. The vcenter is 4.1 build 258902 and the esx servers are 4.1.0,260247.

    When you storage vmotion RDM it converts it to a virtual drive and when he tries the vmfs block size is smaller that the actual ROW (must be more than 256 GB) then you get this error. the data contained in the ROW will be always available. Why not start it because it won't hurt

    Try resetting your device. This will not erase your data stored on that device.

    • Press and hold the sleep/wake button
    • Press and hold the Home button
    • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

    Alternatively, you can go to settings - general - reset - Reset all settings

    If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

  • Migration of storage with RDM

    I images migration towards a new framework for storage. Things work really well, but I hit came across a few images which have been implemented several there are many moons with RDM. The kicker is that they are in physical compatibility mode, so I can't just migrate and convert them to a vmdk. Any thoughts on an approach to migrate? Only the approach that comes to mind is to use VMconverter. This would require a little time to stop, so I'll have to postpone this possibility. I have a lot more flexibility on when I can migrate images if I could use the motion of storage because it requires downtime for images. At least there are only a small number who fall into this category but are images that are among the largest disc attached to like 500G - 1 TB...

    Buck

    Buck - I realize this post is old, but I came across it and thought I would fill you in on how to migrate LUNS RDM in physical compatibility mode.  I read so many messages saying it's impossible, but it's actually much easier than you think, but the virtual machine must be turned off.  Here's how:

    (1) log into the ESX console as root

    2) go to your virtual machine folder: / vmfs/volumes/vmfs-volume-freindlyname/vm-folder.

    (3) locate the pointer to your disk file, this isn't the file - vocation, it's the servername_1.vmdk, it's only a few KBs, inside he does nothing but point to the real disk file, which in this case will be servername_1 - rdmp.vmdk.  It is the file servername_1 - rdmp.vmdk maps of the e/s to the real lun which is still represented by ESX as something like vml.xxxxxxxxxxxxxxx and can be found in/vmfs/devices/drives.

    The source that you want to migrate (with this method, it is in fact a copy which is good, because the source is always left intact) can be a virtual disk, virtual rdm or physical rrdm, it is not «question, you will always use servername_x.vmdk as source file in the command string, you're about to see...»

    but before I continune, if you want to migrate LUNs compatibility mode physical to a new lun to physical compatibility mode, be sure to have configured the lun so that ESX can see.  If you convert virtual RDM of RDM physical mode, the same applies.  If you convert it to a virtual drive, just be sure to have a volume of vmfs with enough space to accommodate the new drive.

    (4) it is here:

    To migrate and convert physical RDM in virtual disk:

    vmkfstools-i servername_1.vmdk/vmfs/volumes/vm record/name of the server - newdisk_1.vmdk

    To migrate and convert physica RDM virtual RDM, there are two methods

    -in vi edit customer of VM VM settings, remove the drive mapped to vocation, off voltage then re - add a new hard drive by selecting the same disk make sure you only select virtual fashion, connect you and see all your data and mount points are the same.

    -from the ESX prompt in the folder of the virtual machine on the VMFS volume:

    vmkfstools-i servername_1.vmdk d rdm:/vmfs/devices/disks/vml.xxxxxxxxxxxxxxxxxxxxxxxx/vmfs/volumes/vm record/servername_1 - rdm.vmdk

    To migrate a new physical RDM physica RDM:

    vmkfstools-i servername_1.vmdk d rdmp:/vmfs/devices/disks/vml.xxxxxxxxxxxxxxxxxxxx/vmfs/volumes/vm record/servername_1 - rdmp.vmdk

    EXPLAINED command strings:

    vmkfstools-i is import-command clone

    the servername_x.vmdk is the source, the x will be held for the command of the unit, in my example I use this 1 which means that it is the second disc on the virtual computer.  the first disc file is servername.vmdk, it is generally always the system disk.

    the-d is the disc type for the destination you are converting to

    the rdm (p) is part of the type of drive saying the destination disk is gross, virtual or physical disk mode (the p stands for physics course)

    folder/servername_1 - rdm.vmdk/vmfs/volumes/vm tells us where to store the raw disk mapping file, I chose to put it in the folder of the virtual machine as you can see, you can put it on any vmfs filesystem, I like to keep things neat and clean.

    Hope you find this useful, don't let anyone tell you that you cannot migrate a physical RDM.  His false information.  This is how its done.

  • iPhone/iCloud storage issue

    I have a 64 GB iPhone 6s and 200 GB of storage iCloud. Whenever I plug in my iPhone and watch my storage, I see that I have Photos 14.12 and 27,67 GB of data and Documents on my iPhone. However, I use iCloud for photos and helped my office and documents on my MacBook Pro to be accessible from iCloud. My question is, why do I all this on my iPhone when I thought that it would be on iCloud? Wouldn't that means that it would not directly on my phone and I have a lot more space on my phone?

    (Hard drive in the sky)-based solution to what you think, is that iCloud is a traditional cloud, but in fact, it is not.  It is a system of synchronisation/mirroring, i.e. post all your data and fills in all of your devices is available immediately.

    If you are looking for traditional storage cloud base, you will need to consider options/third-party applications, for example for pictures - Flickr, Dropbox, Google; and for notes - Evernote, Google Dungeon, etc.

    I have a 16 GB iPad, but in the settings it says that 11 GB of capacity. I am aware of system files, but thought it was a lot, its 4.3 GB so its loss of 30 percent of storage.

    On my mini iPad 2, I've only used about 2.4 GB of space.  However, my iPad said I used 10.3 GB.  I can't understand what is eating space.  On a side note, even if my iPad is WiFi only, I'm somehow able to play music that is not downloaded to my device, even when I am not connected to WiFi.  There may be some songs that are downloaded, and yet it does not show as in the Section "managing storage?

    It seemed to me I found the problem, but I believe that the fix is only temporary.  Sort TV shows, music, etc. downloads when I listen to WiFi and rest on my iPad, but does not appear in 'storage management.

  • MacBook Air storage issues - I have iCloud but using too much data, which is a better solution?

    I have a Macbook Air processor intel and storage 4 GB, I use iCloud for storing all my data, but recently I had a problem with too much use of my data internet home. We are limited because we live in a rural area. So I guess I have two questions: 1) can I use an external hard drive to avoid having to use my iCloud? and if I do which is the best to use external storage drive? I have a lot of files and photos, I am a real estate agent. I got this Macbook Air since September 2015 still invite us to her also. Next question, can I use another Mac with a bigger hard drive instead of the MacBook Air? My son told me in the Macbook air because of its features, but the storage for me is imperative. Please notify

    Use many small external drives that you can carry in your pocket that connect to the computer via USB 3.0. Shop for them at Amazon.com.

    BTW, 4 GBs is the memory of the computer, no storage. MBA come with built-in SSD from 128, 256 or 512 GB capacity. You choose the MBA with the SSD model that best fits. However, once you make the computer cannot be updated.

  • Storage issue on Apple TV (4th Gen) new screensavers download

    Hey guys,.

    I couldn't really find an answer out there on a question about storage on the new ATV4.

    New screensavers Ariel are impressive. As most of you know there is a new option to download new videos daily, weekly, ect...

    Just below it warn you that downloads can take up 600 MB of storage. Considering that I have the 32 GB model, I was curious to see exactly how it works. There is no place in the general settings that show all of the files real screensaver downloaded in order to manually delete to free up storage.

    Are replaced by the new, old screen saver because they are downloaded? Or am I earning the 600 MB each day as a new screensaver downloads? If anyone has any info or advice, I would really appreciate it. Thank you guys!

    Happy new year to everyone

    Yes, each screensaver is about ~ 200 MB. So if you choose all day every day about 3 new vids are added and 3 yesterday are replaced.  Every month means that you get the same videos every month. There is no 'user management' for storage on the ATV.  It's some people have limits of data and do not want to use their allowance for a change of daily screensaver...

    Hi Ben03,

    Unfortunately, the storage can be increased beyond 100 GB, but I would ask to contact customer service for more information on this.

  • CC storage issue

    I just bought the basic plan CC for $9.99 / month. I imported an image 150 and now I'm out of storage. I don't understand how it works? Am I supposed to edit then send them elsewhere? I know this may seem like basic questions, but I hope someone can help. I'm new on this and just to start. TIA

    2G refers to all of the storage space of cloud allotted it under this plan, the portable, mobile, no matter what.  If you need more space than you need to anticipate what it yourself or switch to a different plan that offers more.
