LUN cannot be added without formatting

Hello

Details:

2 x ESXi 4.1 HOST (HP DL380G7)

1 x HP MSA2012fc

The MSA are directly attached to a FC HBA on each server.

I have two LUNS on the MSA (1 TB = LUN_0, LUN_1 = 1.6 to)

The two HOSTS of ESXi 4.1, I have access to these two LUNS.

My problem:

I have updated the first HOST to ESXi 5.0.

After the installation, I have two data store in the Configuration. Local data store and the LUN_0 data store.

I jumped on the storage card and made a new analysis. On the FC HBA, I could see three courses:

1 attachment

2 LUN_0

3 LUN_1

I jumped to the storage and also press Rescan. Nothing happens.

I press Add storage. ESXi 5.0 shows me my LUN_1 and I click Next.

Now seems to me that I have to reformat the LUN. I can choose something else.

I can't do this! On my LUN_1 are my productive VM.

Does anyone have a solution for me?

Beste wishes

Martin

Your solution could be as simple as the LUNS need to be mounted on the other hosts.

In one or more of the hosts do not show the LUN and type of PuTTY

esxcfg-volume - l, lists usable LUNS that are NOT mounted, if no LUN is displayed it means that all your LUNS were mounted.

If you see LUNS listed in the above command, type this to mount each one LUN at a time

esxcfg-volume - m "vmfs_label_name", the name of lable must be the friendly name you gave the LUN when initially formatted.

I had this same problem with one of my ESXi hosts and this took care of it without formatting.

It may be useful

  • How to add a LUN VMFS format without formatting? in vSphere 5.1

    Hi people, we need to mount a store of data that was previously seconded.

    Is it supposed to be an option called: EnableResignature or > DisallowSnapshotLun but is not present in vSphere 5.1.

    Can someone has a workaround for this? We just need to set up a data store without formatting!

    We use vSphere 5.1 Ent.Plus Lic.

    Help, please!

    Concerning

    You can always re - mount an individual to a host data store if he is always aware that the data store was just disassembled.

    Options EnableResignature or DisallowSnapshotLun is relevant only if you present a new LUN with the VMFS volume to a host that already has a volume mounted by the same UUID of VMFS (for example a volume snapshot of SAN-side).

    Since few releases ESXi, you don't even have to set the options manually beforehand. It comes when you add the data store in the vSphere Client will ask you what to do, whether it is the will of the volume. Will simply means just assign another name VMFS UUID and the data store, that's all.

    He does not reformat the LUN. So that you can move forward, then up the LUN.

  • Move LUNS from physical Windows area to an ESX VM without formatting

    Hello. I'll convert machines physical (with converter stand alone) in virtual machines on my ESX servers.

    These servers have local drives (for the OS, the quorum and other data readers) as well as multiple LUNS.

    First question:

    My thoughts were to convert only local drives (jump the LUNS as they are already on the SAN). Then have the path of the SAN people (let me see) to my ESX servers. BIG draw back is that when I first plug a logic unit number, he wants to format. How can I connect to it and knew him ESX as store data without formatting? On the page [disk/LUN - formatting], there is no way NO format.

    Second question:

    When you allow an ESX box to see a logic unit number that uses a Windows box, there is assertion that ESX wouldn't let me even see. It happens just to expiry. Is anyway about this or what I was removing people SAN paths to my Windows boxes and then add first to my ESX boxes later?  The SAN is controlled by another agency and this would add a lot of time in the middle and these servers are critical and can not be down for long.

    If anyone can provide fairly detailed steps I would really appreciate it.

    (1) you can use these LUNS as RDM (raw device mapping), in which case you do NOT have to reformat them.  You just create a mapping of RDM.  See page 140 of this document: http://www.vmware.com/pdf/vsphere4/r41/vsp_41_esx_server_config.pdf

    (2) Windows will apply the locks to the volume.  You need service entirely volumes of old guests prior to commissioning for the new ESX hosts.

  • External hard drive does not work. Is there another way I could solve the problem without formatting the external hard drive?

    My external hard drive works. I tried to plug and when I tried to open it, it says to format the drive until I could use it. Everything works well as when I plugged the USB icon shown on the screen. When I check the disk management, it showed that the partition of the drive is there.

    I tried to change the drive letters, but still having the same problem. I also tried to run the disk check on the command prompt and the properties of the drive, but it still can not because there is error popping up saying that the disk check cannot be performed because Windows cannot access the disk.

    Is there another way I could solve the problem without formatting the external hard drive?

    I tried the first step in troubleshooting the hard drive, but it gives a
    error in saying that "hardware changes might not have been detected.

    So I tried the second method, and when I click on the "Check now" button his
    gives an error saying that "the disk check cannot be performed because .
    Windows can not access the disk".".

    So is there any other way or option?

  • Can ' RAW be converted to "NTFS" without formatting?

    I replaced the power supply in my Dell Dimension 8200/Windows XP and added a new WD 250 GB HD as my master (C) and moved the may have "damaged" Maxtor 80 GB to the position "slave." Both hard drives are recognized as 'online' and 'Healthy' disk management, but 'C' is listed under the "NTFS" file system while 'E' is empty and listed as "RAW" file under properties system. The two HDs show scores. How can I convert the RAW file system in the primary partition of the HD 'E' slave without formatting and losing my data? Haven't found the "recovery discs" for sale online that appeared "reliable." Thanks in advance!

  • How can I install Windows 8 of my 1.5 TB external harddrive without formatting?

    Well I finally decided to move to Windows 8 (starting from Windows 7 x 64), but I'm stuck in a weird situation here...  I image .iso Windows 8 with me but I will not be burn on a DVD, the only option would be either use a USB key or an external HARD disk... Unfortunately my 16 GB USB DRIVE no longer works (and the .iso image file does not in my other USB drives I had remaining)... So I decided to use my drive external HARD on the contrary - but there's another problem... about 750 GB on my HARD drive is full (there are all my files, movies, music, games, etc) and the rest is 'empty '...

    So, how can I install Windows 8 of this external HARD drive without formatting? Since I don't have any other "spare" hard drives or USB keys with a lot more storage capacity...  And I can't keep them in my laptop because it has only 500 GB...

    Can I partition my external HARD drive and secure all my files in one partition, and format the other partition to use it to install Windows 8 on my laptop somehow...?

    You can create a partition on your HARD drive and install Windows inside with Universal USB Installer
    Here's how you create a new Partition
    • Open disk management
    • Right click on the partition that you want to split > Shrink > select size > Ok
    • Unallocated space will appear
    • Right-click on > Format give a letter

    OR you can install windows on a different partition from your internal HARD drive

    You can create a partition in the internal drive and extract files inside Windows and make it bootable with EasyBCD (3rd party free program to change startup options and other things)
    • Create a new partition using disk management
    • Extract the files to install Windows inside
    • Open EasyBCD > add new item > WinPE > search for X:\Sources\boot.wim > add
    • Reboot and choose the new element added to the startup in
    I used this method once and it worked
  • Satellite A200-237: Visat Installation without formatting the two partitions

    Yesterday, I installed Windws Vista and all other software for my Satellite A200-237.
    A has 2 partition of my drive hard C and E.

    I used E for my files just like I did with my computer laptop formar.
    And when I installed windws xp that I formatted only C and E remained as it was, so I've always had my files on my laptop. I did the same with my formatted partition C AND e. visat toshiba and vista and unfortunately I lost all my files and I now have the partition C and F instead of C and E.

    Is it possible (for the next time I re install vista and format the hard disk) without format my second partition?
    Is this possible or do I really have a second HD?

    I do not remember Vista asking me what partition I want to format and with XP, I had that choice.
    Help, please.

    Hello

    Well. Usually it of possible, but only by using the original CD of Windows Vista.
    Then, you choose the partition where the operating system must be installed.

    Using the recovery CD all partitions will be deleted simply said; the recovery CD formats the entire HARD drive and you will lose all the data stored on the partitions

  • How can I change the permission of my external hard drive from tours and write "without formatting?

    My Toshiba external hard disk format was automatically replaced Windows NTFS after I had plugged on a Windows PC. Therefore, the permissions of the drive changed to 'read only' to "read and write" after that I used on my Mac. It happened once before and I remember the engineer on duty in an apple authorized service center had solved the problem without format the external hard drive. This is not an option for me now as well, but all the solutions, I looked to say online that the formatting of the disc is the first step. Help, please!

    Install software such as Paragon NTFS on the Mac.

    Hello
    I have a qosmio G20 bought in October 2005. I need to repair my OS. The CD/DVD provided with the Windows XP MCE do not provide an option 'fix' as one provided when you buy a copy of Windows. How can I repair my OS without format my laptop?

    The supplied restore CD does not contain the repair console because it s not an original Windows CD. The restore CD contains only an image of the files. Don't mix it with the CD of Microsoft!

    To get into the repair console, you will need the original CD of Microsoft Windows.
    I also read on the Microsoft site that it of possible to download the repair on 6 discs FDD console. Then you could boot from this drive FDD and you might be able to get into the repair console. But I have never tested this procedure.

    After the end of my second day of test error, I put this question on the table:

    Another clue. If you check using DIAdem

    you are able to install the debugger in DIAdem.

    It would potentially have shown that the command does not work as expected.
