Install ESXi 4.1u1 USB to USB

I have a N36L HP Proliant Microserver, on which I want to install ESXi 4.1u1. The material has no optical drive, but it has an internal USB that can host a flash drive. I want to install on a 1 GB stick plugged into it. It is two a question on how to do this, but also what I've discovered so far.

(1) my first attempt was to create a portable USB HD bootable with ISO. It is documented in various places, the easiest of which is to use UNetbootin. Although apparently, it worked in previous versions of ESXi, apparently this does not work in 4.0 + since the installer insists on finding an image on an optical disc instead of the bootable media.

(2) the workaround for this is to use a kickstart file to call 'usb install', which has the secondary effect of automation of the installation too. However calling "autopart' with the name of the flash drive fails also in my case because scripted installs need to 5 GB of space on the target disk. My stick is 1 GB.

My remaining options are:

(1) use another VM (possibly?) with an optical drive to install on a USB thumb key and then plug it into the server. Would this work? Is there only one image for all types of hardware, or installing regular CDROM EXSi when thing custom installed on a specific material does something?

(2) use a "image writer" (winimage/dd) to write the installation image to ISO directly on the USB. To do this, I have the same questions as above. The images fit everything?

3) temporarily renounce this strategy and use a cdrom or install it on a hard drive instead.

Any help would be appreciated!

Option 1) would do. A base image would work different across of the box. You will find another server or using vmware workstation to create your bootable USB on esxi.  You can follow the tutorial here simply replace these virtual CD ISO of vmware workstation. http://www.techhead.co.UK/installing-VMWare-ESXi-4-0-on-a-USB-memory-stick-the-official-way

  • My concerns about installing ESXi on a USB Flash Disk

    Hello!

    There was a lot of messages about installing esxi hypervisor on a usb flash drive, what I've done and I think it's ok because there's no need to waste expensive disks for installation of a very light bone

    But I have a few questions and concerns in this regard. appreciate your answers.

    1 - first of all I can't find my DL380 G7 Server internal usb. can someone give me a link or a picture where he is exactly?

    2 - Suppose that after boot completely the host, something happens on the usb drive. If nothing happens? I think there should be nothing to worry about, because the hypervisor has been loaded into the memory of the server. Am I wrong?

    3 - my concern is to have backup and the ability to restore that very quickly. some time in the past I had a single esxi host. I used powercli and commands appropriate for configuration backup host (I think that the command was something like esx-cfgbackup or like that).

    so if the flash has been corrupted, I would replace it with another and restored the settings that

    but now I host 4 esxi and vcenter. should I worry about this? How should I have backup? I know that SQL backup database of vcenter and its certificate is sufficient to have a backup of the settings of vcenter but on those who are just to vcenter and which are on the host? just want to say, what should I do to be able to replace a faulty usb disk (esxi is on it) with a new and all get back to work as it was?

    Sorry if the questions are easy to answer. I'm just a beginner

    and sorry for my bad English

    Assuming that I don't have the license for the host profiles, what should I do?

    It depends on the complexity of the configuration of the host. You can back up the configuration of the individual hosts or just reconfigure reinstalled once. In a larger environment, you'd probably for example the hosts scripted installation.

    Because the server vCenter Server usually runs as a virtual machine, it is a good idea to do an image based backup (using backup vDR or 3 rd-party applications), and - in the case where you use a dedicated SQL Server - certainly back up the database. For the backup and restoration of vCenter Server, you can also take a look at http://kb.vmware.com/kb/1023985.

    In the rare cases where an SD card fails, you can always vMotion virtual machines to another host and then reinstall the host with a new SD card.

    Yes it has an internal USB slots (2) and Dell Power Edge T310 is the HCL just check your CPU

    People had a lot of problems installing ESXi4 on boxes, but it is associated with RAID controller driver.

    This should be included and sorted on ESXi 5: see http://communities.vmware.com/thread/243513?start=15&tstart=0

  • ESXi on a USB

    Hello

    I like the idea to install ESXi on a USB key. Took a test today on DL380 G7. First available opportunity Sundisk 4 GB stick... Run absolutely perfect.

    1. I read earlier on this forum about model particular Sundisk (recommended).

    Please advise...

    2. how to the backup of the key with ESXi installed on it. I know that the host continues to operate, but I would like to know how to make a reliable backup.

    Thank you.

    You want a quality certified USB 2.0 key.  A particular brand is not a requirement.

    For the backup of your ESXi host (the config only) you can use vicfg-cfgbackup of the vCLI or Get-VMHostFirmware of PowerCLI.

    vCLI - http://www.vm-help.com/esx/esx3i/esx_3i_rcli/vicfg-cfgbackup.php

    PowerCLI - http://blogs.vmware.com/vipowershell/2010/12/better-firmware-management-in-powercli-411.html

    In the case of having to recover you launch the ESXi installation CD, set an IP address for management, patch your webhost to match the version running in the latest backup and then restore your backup file.

  • Preparation for the integrated USB ESXi 4.1u1 key

    Hey guys,.

    I just want to check that the method I use to create my key USB ESXi is healthy.  I think that the official production method to use the ESXi Installable on a CD and then install VMware ESXi on USB media, and this is considered to be "shipped".  Instead, I chose to use the SD method and write straight on the USB.

    I extracted: "imagedd" of Imagedd.bz2 in the HP provided ESXi 4.1u1 ISO April release.  The ISO was titled: "4.1_U1_Apr_2011_ESXi_HD_USB_SDImgeInstlr_Z7550_00096.iso" this iso includes all CIM providers for monitoring of hardware, drivers and others.  Also, I did an md5sum against imagedd and checked that it is exactly the same as that provided by HP.

    Under Linux, I plugged in my USB drive which has been recognized as a certified HP: / dev/sdb

    Then as root, I typed: dd if = imagedd of = / dev/sdb bs = 500 M (I forget if it's 500 MB or 500 M, just a note)

    I then tested the stick on a separate portable 64 which has virtualization features.  Everything looks good, ESXi 4.1.0 started very well.

    Any thoughts against my method before I pull the trigger here?  I'm sure I need to configure the zero (newspapers and others) for hard/VMFS disks at any given time.  Thank you.

  • Installed ESXi on USB/Flash but swap does not seem to have been placed on the virtual disk

    Hello

    I've read several times that when you install ESXi 5.1 on flash media he creates a work space available on a virtual disk of 4 GB in/tmp/scratch so that the USB itself is not used for temporary data to extend the life of the USB.  However, this doesn't seem to be from my experience and I was wondering if someone can help me to confirm that my disc scratch is actually on a virtual disk or whatever on the USB.  I should mention as well as installing ESXi has identified correctly as 'flash' disc type and the disc as a "Generic USB drive»

    After installation, I noticed two things:

    1 log-in user activity logs are able to survive a reboot (I don't think they should the ramdisk is dissolved after a reboot)

    2. There is no directory with the path/tmp/scratch

    Unfortunately I can not directly determine where the partition scratch is (be it on USB or RAM) because I did not have a file ' / etc/fstab "watching (even if I under ESXi 5.0 disk a hard base install?) and it doesn't seem to be a 'mount' command I can use to look at the existing mounts either.

    Can anyone tell me what can I do to verify that the directory used for temporary files is actually a virtual disk and not on the USB drive itself?  Hours of research are presented only the forum messages and documentation clearly indicating that the file will use "/ tmp/scratch", but that just isn't the case.

    Thanks in advance for all your help.

  • Install ESXi 5 on a usb flash drive

    Guys,

    What is the minimum space required when you install ESXi 5 on a USB?

    Kind regards.

    Hello

    I came across this time, since it doesn't seem to be documented nowhere in official documents, not in the knowledge base and not in vSphere Guides 5.

    But if you run the installation you will be asked to "Select a disk that has a capacity of more than 910 MiB".

    So, this would be the answer I guess

    I am having trouble to make the iscsi boot and mused with a temporary workaround.
    I want to install vSphere 5 on a USB key, boot on USB and when all the problems with boot iscsi are resolved, use vMotion to migrate the virtual machine to another ESX host.

    What are the advantages and disadvantages regaring USB-install?

    Maybe it's even better that run start iscsi.

    Hello

    We have no difference between USB install and install ESXi on hard drive. all functions and features are the same. You have following additional configuration on USB Installer if necessary

    -Remote Syslog configuration

    -Netdump configuration or change the coredump on hard drive partition by creating additional VMKcore on hard drive.

    -Try to use the qualified USB key (refer to the hardware vendor documentation).

    Not looking for any specific limitation other than mentioned above.

  • Flexible scenario using ESXi 4 on USB

    Hi all

    I intend to get a good USB 2 GB and install ESXi in it, can the following scenario happens using USB install ESXi?

    No need to reinstall the ESXi when existing local RAID hard drive changed on the data store, since I can just

    1 VMotion the VMS and empty data store

    2. stop the ESXi

    3. disconnect the USB

    4. perform the reconfiguration of RAID.

    5. plug the USB back again and the bot the ESXi

    6 detect the new data store, format as necessary

    7 return the virtual machine to the new data store?

    is this feasible?

    Kind regards

    It works completely. Not need to unplug the USB unless your server is not a way to start directly in your raid tools or a CD.
