ESX 3.5 and I seem to have lost all the networks.

DL580 G4 with ESX3.5. I've migrated all clients to another ESX Server, but it went a bit strange to say the least.

After the migration, all the guests off I went forward and add more ram and restarted. Server come OK, tells me the IP address to connect to (static) but that's all.

I can ping 127.0.0.1, but not static host ip address, I get an error "connect: could not connect to the network.

If I check the following localions I get zero information in files

/ etc/hosts

etc/network-scripts/ifcfg-vswif0

etc/VMware/ESX.conf

If I try the list of network adapters that I get no NICs in the list, if I have the material list network get hardware type and mac address.

I see no switch to vmware if I try esxcfg-vswitch - l

I tried to restart the network and a few other services that I found on Google, now claim.

If I start using ERD Commander and enable networking I can not use the 2 onboard NICs but can use 2 additional network cards / 4 ports and can ping / map of external drives.

Hello

I think it would be a case of corrupted file esx.conf. After the upgrade of the host by adding more ram or anything else, you may need to update the initrd image that you don't have and this translates into the corruption of your esx.conf file. Until that time, that it's the only imagination, I can take.

Now, there are simple process of recovery of the original esx.conf file. Please see the procedure below.

#

Connect to the ESX host with a SSH client, or connect directly to the ESX with KVM console.

#

Back up the corrupted file esx.conf using the command:

CP esx.conf /tmp/esx.bad

#

Copy the image into a temporary directory using a command similar to:

CP /boot/initrd-2.4.21-47.0.1.ELvmnix.img/tmp

Note: The version of the initrd image is different from the ESX 3.x. If the version in the command / tmp /boot/initrd-2.4.21-47.0.1.ELvmnix.img cp is different, cd to the directory/boot and run the ls command to see your version.

#

Decompress the image file using the command:

CD/tmp

gunzip - dc initrd - 2.4.21 - 47.0.1.ELvmnix.img > initrd.unziped

#

Create a directory and mount the uncompressed image using the commands:

mkdir initrd

Mount-o loop initrd initrd.unziped

#

Copy the file esx.conf to the directory mounted at/etc/vmware/en using the commands:

CD/tmp/initrd/etc/vmware

CP esx.conf/etc/vmware.

#

Remove the directory mounted in step 5 by using the commands:

CD/tmp

umount/tmp/initrd

#

Restart management agents for the changes to take effect.

Now other solutions could be looking to recreate the Console of the ESX Service and see if that can help you. Procedure is as below:

On your system, the vswif, vmnic, numbers of vSwitch and network settings are different.

1.

Run the following command to list the name of the map of vswif:

esxcfg-vswif - l

2.

Run the following command to remove the adapter vswif:

esxcfg-vswif - del vswif0

3.

Run the following command to list the name of the vSwitch:

esxcfg-vswitch - l

4.

Run the following command to remove the vSwitch:

esxcfg-vswitch vSwitch0 d

5.

Run the following command to create the vSwitch:

-an esxcfg-vswitch vSwitch0

6.

Run the following commands to create ports for vSwitch default groups:

esxcfg-vswitch - a 'network of the VM' vSwitch0

esxcfg-vswitch - a "Service Console" vSwitch0

7.

Run the following command to create the adapter vswif:

esxcfg-vswif - add-- ip = nnn.nnn.nnn.nnn-"Service Console" portgroup mask = 255.255.255.0 subnet vswif0

8.

Run the following command to verify that the settings in the network file are correct:

sysconfig cat

Networking = yes

GATEWAYDEV = vswif0

HOSTNAME = Host.domain.com

Gateway = nnn.nnn.nnn.nnn

9.

Run the following commands to list all network cards and associate a vmnic which has a status of site link:

esxcfg-NICS - l

esxcfg-vswitch - L vmnic1 vSwitch0

10.

Run the following command to verify that the vmnic is associated with the vSwitch:

esxcfg-vswitch - l

11.

IP address ping to verify network connectivity. If the ping fails remove the previous vmnic from the vSwitch and try another adapter that has a

State of the link towards the top.

esxcfg-vswitch - U vmnic1 vSwitch0

esxcfg-vswitch - L vmnic2 vSwitch0

12.

Run the following command to change the ID vlan a vSwitch

# esxcfg - vswitch - p "VM network 1" - v 10 vSwitch0

13.

If you make manual changes to sysconfig, run the following command to restart the network service:

service network restart

  • 2015.3 CC - have lost all the file audio problems video / links too

    I've upgraded to 2015.3 this morning.  Started working with a project that was shot entirely with a Panasonic GH2... and have never had any problems with it. Now in 2015.3, the project opens with none of the video on the timeline linked to their respective folders. When I try and make the link... video links and there is a message that tells me the audio isn't there... specifically the message is: the selected file contains audio media used by clip references in one or more sequences. These references to audio clip will be deleted and cannot Ωtre annulΘe. Do you want to continue? OK Cancel of course that I have to cancel, not knowing if the audio will be permanently deleted. Files from the GH2 are .mts files and it is certainly audio when played with a media player. So my question is... is this a problem with the format .mts or it's Adobe. I'm afraid to open another project that has files, .mxf or mp4 and brought them to the point completely dissociated.  Here is a screenshot.  Can I just go back to 2015.2 until find you it?

    I had problems with links in emails not open their web pages when I clicked on them. I've read some of the info on the help and decided to reset default Firefox. Later, I realized that my "downloads" had been removed. Is it possible to restore these because they are all related to Internet Marketing elements such as plugins, I downloaded ebooks, scripts etc etc?

    I looked in the folder that was created automatically by Firefox on reset but I can not find them in there!

    Hi Nancy,.

    Encryption of files and folders is a way to protect against unauthorized access. EFS (ENCRYPTING File System) is a Windows feature that you can use to store information on your hard disk in an encrypted format. Encryption is the best protection that Windows provides to help you keep your information secure.

    You can make a folder and then encrypt it.
