Key USB VMFS format

Hello, I am new on ESXi and use a server at home as a learning tool. I just installed ESXi 4.0.

My configuration is: host with ESXi 4.0 running from USB (4 GB), my main drive of the virtual machine is an array of two drives of 250 GB RAID1 and my storage "in bulk" is a disk of 320 GB SATA (non-RAID).

My goal: save the main VM walk on a portable USB drive.

I bought the USB it's a WD My Passport 250 GB drive.

After you have enabled SSH, I plugged it on the host computer, via SSH, I can see the operating system recognizes (it appears in fdisk - l). I then run fdisk /dev/disks/mpx.*** (laptop drive), delete all partitions, create a new partition, primary #1, type VMFS and configured to use the entire disk. I write the changes to disk, and after a fdisk-l reflects the changes... Everything is good.

I was not sure how much exactly on what FS to put it on disk, but eventually see only how VMFS from the ESXi host (as much as I KNOW I can't format it ext3 to ESXi).

The problem: I run: vmkfstools - ch. /dev/disks/mpx.vmhba35*** vmfs3

After half a second, I get the following error message:

Creating vmfs3 file system on "mpx.vmhba35:C0:T0:L0:1" with 1048576 block and volume, "nil".

Usage: vmkfstools - ch. vmfs3/vmfs/devices/disks/vml... or,

vmkfstools - ch. vmfs3/vmfs/devices/disks/naa... or

vmkfstools-c vmfs3 /vmfs/devices/disks/mpx.vmhbaA:T:L:P

Error: failure of vmkfstools: vmkernel is not loaded or not implemented call.

In looking at unpacking, I see the following relevant lines:

(Jul 21 00:54:15 vmkernel: 0:01:49:47.825 cpu0:4103) NMP: nmp_CompleteCommandForPath: command 0 x 16 (0x41000409fcc0) for device 'mpx.vmhba35:C0:T0:L0' NMP failed on the physical path 'vmhba35:C0:T0:L0' H:0 x 0 D:0 x 2 P:0 x 0 valid sense data: 0 x 5 0x20 0x0.

Now, I did some research, but did not come to the top with a little (unfortunately like most things ESXi). The head alone, I got was something about the blocks. So I tried the same line vmkfstools with different-d 1 m 1 m to 8 m with no luck, still the same problem...

Someone would have an entry on it? I'm a little puzzled.

Thank you very much, I appreciate the help.

I know, you cannot format a disk/USB with VMFS.

Is unsupported and seems it is not possible.

  • Update of key USB IBM

    Hi guys,.

    You just bought key USB IBM. They are version 5.0 how update 5.1? I can download an ISO, but don't know how to get it on the USB sticks?

    You should be able to boot from the ISO that you downloaded and select the existing USB drive as the installation drive. When the installation program detects an existing installation of ESXi and VMFS datastore you can choose to upgrade ESXi and preserve the VMFS datastore.

    Just take a backup before you do so that you have a roll back option.

    See the link below;

    http://pubs.VMware.com/vSphere-50/topic/com.VMware.VCLI.examples.doc_50/cli_manage_hosts.4.4.html

    Important: The vicfg-cfgbackup command is available only for ESXi hosts. The command is not available through a connection to the system server vCenter. No equivalent command of ESXCLI is supported.

  • Satellite A500 - 14K - key USB not recognized with Windows 7

    I have a Toshiba Satellite A500 14 K, it was pre-installed for Windows 7.

    There was no particular error in these facilities.

    Since this upgrade, my PC doesn't recognize USB keys while they work perfectly with the previous version of windows with this pc. They are normally key usb plug-and-play. When I launched the update of windows, the driver exists, but installation failed in error with a message of access problem.

    Hello
    I am usiing the key USB DVB - T Tuner TOSHIBA PX1211E-1TVD and can not find a driver for Win 7 64 bit.
    Are there Tom Driver for this OS?
    Or is it possible to use it without a specific driver? I mean something like BDA or more (I don't know-.-)

    Tanks

    Hello!

    > can not find a driver for Win 7 64 bit.
    Why you can t find a driver? What do you think could be the reason for this? Is it really so strange?

    Let me give you a little tip: Windows 7 is not yet on the market and so there is no drivers for Windows 7 available. All that s!

    You can try the Vista drivers because most of them also works on Windows 7, but it's all for the moment you can do.

  • Help? With the help of file system Ext3 on key USB on Linux RT target

    We have been affected by problems with the SD cards and USB drives formatted in FAT32 on some devices, according to Linus RT of long-term monitoring (mainly the cRIO-9035). It seems that readers are vulnerable to fluctuations in current and unexpected reboots (which are inevitable on these sites). Write aborted operations make the damaged discs, thus sabotaging logging after reboot.

    We have identified two solutions; implement both gives the best redundancy:

    (1) installation of UPS (uninterrupted power supply for emergency supplies/batteries) - done

    (2) using the file system apparently more robust 'ext3', which is available on the target RT Linux (FAT32, ext2 and ext3) - don't have not so far:

    ->, I was not able to properly format a USB stick for ext3. I use the MiniTools Partition Manager and don't get any errors when create and format partitions. But they appear as 'read only' when it is inserted into the chassis of the RT. All attempts to access it, other than to observe the empty folder sdxx in ' / media "is returning errors.

    Someone had a bit of luck with the help of ext3 disks formatted as data drives on the objectives of the RT Linux? It is worthwhile to solve my problems or should I use FAT32 and the observed risk?

    I do not consider this but a temporary solution:

    I ran into issues when you use MiniTools Partition Wizard to partition and format my thumb on Win10 records. An unidentified change makes the inaccessible disks and freeze the browsing of file on the PC when I try to delete the partition. It was quite annoying!

    I decided to try another partition tool and went for the EaseUs Partition Master (free version for the moment). I formatted successfully one of the troublesome discs with it (to add some uncertainty to the solution, I used another brand sp * banking, new PC to do). The reader now mounted in read-write and allows the startup application create the I want to store files in folders.

    I'm very curious to know the difference between the tools of both partitions and their formatting...

  • Copy (cloning) a key USB of VMware ESXi

    Hi all

    I have a question about the copy of a key USB VMware (a USBkey VMware is an IBM option (in fact, any major brand for that matter) supported). Lack of VMware ESXi 5 from a USB key using the UEFI. Recently the USB has renounced us, so we reinstalled VMware ESXi5, installed updates and set up the latter again and everything works again fine, but to save time to stop in the future we would like to keep a copy of the USB on the tablet. Is there an easy way to easily copy this USB?

    The following would work? :

    1. stop the server

    2 boot from a Linux live DVD

    3. Insert the USB source

    4. Insert the USB of destination

    5 open a terminal

    6. start: If dd \u003d/dev/sda of = / dev/sdb (after checking admesg | grep like command course)

    7. shut down the pc when done

    8. replace the USB source on the server

    9. starting the server

    Is there anyone who has any experience with this?

    Yep - that should do it

    It also provides more efficient storage for initial commissioning management and ongoing management of shared storage resources.

    How can I check the san and the vmfs format is aligned properly?

    Thanks in advance!

    You should not use these programs, but if you want a USB key to install then you should make an ISO file and then using Unebootin according to me this is a best software to USB for xp and if you have windows 7 installed in one of your system, then you can use tool usb windows 7.

  • Does not have the option to format my laptop because of the key USB and CD Rom

    I have my HP laptop, model number HP Pavilion dv6703tx have window 7 ultimate installed on it. I want to format my C drive. To do this, I tried to format it through all the procedures, i.e. through bootable usb pen drive and cd rom, but each time after selecting the language which is English (India) and keyboard in the first page, the next option coming in the lower right, i.e. it is not visible, so that I can click on it to move forward additional formatting. This problem comes from two rom cd and pen drive. In addition I don't have the recovery hard disk partition. Please give me a solution to overcome this problem. I'm very worried about it. :-(

  • OR PXI-8196 target using a USB stick formatting

    Hello everyone,

    I use a PXI chassis with controller PXI-8196 and multiple PXI DAQmx cards. I need to format the hard drive on the target of PXI and reinstall the RT operating system as well as all other software. I am trying to restart the PXI with a USB bootable, but it gives me the option to format the hard drive.

    Here are the steps I followed.

    1. I created the disk bootable with MAX using the RT disc utilities > create Desktop PC USB Drive Utility (PXI-8196 does not have a floppy drive so I have to use a USB key)

    2. I have connected a keyboard and screen to target to see it start.

    3. I've also adjusted the sequence of boot as the boot option "USB HDD: LEXAR JUMPDRIVE SPORT" among those available in the boot sequence has the highest priority. (My USB is a USB of LEXUS so I'm sure that this particular option must be the first in the sequence).

    4 but once I start my system. It does not give me the option to format (according to MAX documentation should give me an option to "format hard drive"). Here's what I see on the screen connected to the target

    = = The output to the screen is bounded by these two rails =.

    5. the 10.10.10.2 IP address is the address in the configuration I want to format and reinstall. So I don't know if he meant to keep automatically previous IP address.

    6. to avoid the fact that there may be something wrong with the USB, I repeated the procedure as a whole with another USB drive. But exactly the same thing happens again.

    Please help me it reboot with a USB port and format the hard drive and reinstall all software.

    Thanking in anticipation.

    Hello

    Stay away from PC World and other 'big box' stores. If you cannot do the following works yourself (and there is no shame in admitting this isn't your cup of tea), take the laptop to a local professional. Get recommendations from family, friends and colleagues.

    1. remove the hard drive and put it in a USB drive enclosure (or use an adapter) and attach it to a working computer. Then, copy your data.

    2. Once your data is safe, put the drive in the laptop and do a factory restore. If all goes well, after that, restore your data from the copy that you made. If everything is not well and/or the factory restore does not work yet, you have the hardware failure. What you do then much will depend on which components have failed and how old is the laptop; that is, it is worth spending anything to fix. MS - MVP - Elephant Boy computers - don't panic!

  • System Dell DataSafe recovery media will not identify key USB

    I am trying to create a system restore USB recovery and DataSafe does not recognize my USB.  I use a 16g SanDisk Cruzer stick, and it does not recognize any of the 4 ports USB (2.0) on my system I use it (No. USB key ' detected').  My system recognizes the stick very well... I can drag and drop onto the key using Windows Explorer.  I tried to format the stick in NTFS or FAT32 and still no go.  Well, to tell you the truth, I guess I can go out and get another USB key.  In fact, DataSafe acknowledges a Lexar stick I have, but it's just a stick of 1 g and I came out and me a larger stick knowing at least 9g would be necessary.  DataSafe does not recognize that SanDisk USB sticks that anyone knows of?  Did I just waste $ 10 on a USB?

    02TBIRD,

    You can find the version number of Dell backup and recovery by opening the application by clicking on the "?" in the upper right corner and go to the 'about '.  If your version number is older than 1.6.2.4, you must click on the "Update" tile in the main screen.

    We have solved many problems of detection of backup and restore Dell v1.6.2.4 USB.

    When you go to the "Update" page, make sure that the "Automatically check updates" is checked.  In this way, you will automatically get updates as we post them.
