Host is disconnected on Vcenter and refuse to connect (ESXi4)

[Ometa]

One of the the Host (running on Hp Proliant Dl 570)  with ESXi4 is disconnected and refuse to connect to the vcenter. I was try to reboot the server. From now, I 'm able to ping the server, connect over ssg, but not over Http and Https. All attemps reconnect failed. From Vcenter, when I try to add the same Ip address, I got the error " Call Datacenter.queryconnection failed.

I need you assistance.

Thank you

[ChrisDearden]

have you tried to restart the Vmware agents on the host ?

[idle-jam]

try restart the management agent: http://kb.vmware.com/kb/1003490

I was try to reboot the management agent , and It's seems done properly. But the issue is stiil pending

When I was installing vSphere 4.1 ESXi I ran into a problem. I  received the following error when I added the ESXi host to my cluster:

Call “Datacenter.QueryConnectionInfo” for object “yellow bricks” on vCenter Server “W2K8-001″ failed.

Although the error didn’t make much sense I had the feeling it had something to do with name resolution(This KB article gave a hint I guess). After I added my dns suffix on my NIC it worked. Problem solved.

- right click your network adaptor
- properties on your IP4 stack
- click advanced
- got to your DNS TAB
- add your dns suffix to “dns suffix for this connection”

[Ometa]

The DNS Suffix was already done. I have to Hosts on my Cluster and the configuration is the same on all of them.

Any feedback please!

[beckham007fifa]

check for all your host names in the host file. restart the service mgmt, also check for the vpxa and hostd agent. try ping the server from your vc server subnet and check for dns names

if server is not joining by name , join by IP address...if this is also not happeneing, change the IP of the server and then give the same IP again and try adding it.....this may work

[Ometa]

I was able to change current IP, or try to add it with the hostname. Same issue, same error.

Can you tell me how to check on ESXi4 if the httpd service is running? becaues I'm able only to ping and make an ssh on the server.

Thanks

[beckham007fifa]

ummm.....serious problem then...frn, do you have any vm on the local disk or using san? Is there is no VM in the local disk then reinstall the ESX server..

guys....please suggest..

for verifying...

[Ometa]

I don't have any VM client on the Host (all of them are present on the SAN). I can rebuilt a new Host but could you please share with me how to reconnect the old VM on the new host (after reinstallation).

I was send also some log the Hp Vmware Support and I waiting their feedback.

Please share more if it's possible because now it's  critical for us!

[beckham007fifa]

anyhow those VMs are powered on other host right? if not unregister those vm's through command and then register on the hosts which is working , when you rebuild the host you can migrate it easily...

[Ometa]

Very strange

I'm not able to unregister any VM

From the screenshot, it seems like some http config corruption. I may be wrong.

But, Let me know the results if you already had done these.

1) From vCenter Host:  Ping and SSH works ?

2) From problem server (ESXi): Ping to vCenter and rest of the Network Devices works ?

3) Is the Netmask & default gateway on the ESXi and vCenter are same ?

    (On ESXi: esxcfg-vmknic -l, esxcfg-route -l )

[beckham007fifa]

are they VM running?

use this to unregister

vmware-cmd -s unregister /vmfs/volumes/UUID/vmx

or if this is not happening shutdown the host.

and take putty from other working host and register the VM either using VC or this command

vmware-cmd -s register /vmfs/volumes/UUID/vmx

[beckham007fifa]

oops, those commands will work with ESX not sure abt 4i...

are the VM's running?

[Ometa]

1) Yes Ping and SSH on working from Vcenter

2) from critical esxi host, I'm able to ping the Vcenter (hostname and IP)

3) Yes ( the default gateway and the mask is the same)

[Ometa]

Not workining on ESXi4 and note that all VM are down .

[onestop]

Good. Are you able to open vSphere client directly onto the 'critical ESXi' host? If you can do, could you efford power-off one VM from there ?
