Cannot login through vSphere after upgrade

Hi,

I've just finished an upgrade process on one of our hosts from ESXi 3.5 to 4.0. All seemed to go well, the vSphere upgrade utility crashed after the upgrade process reached 100% but it happened to me before so i ignored it. The host booted up fine but now i cannot logi in to it using the vSphere client. the message i get says "Cannot complete login due to an incorrect user name or password." I've changed the password few times and it works when I'm logged on locally to the server, i.e. I can shut it down or change config. The authentication doesn't work throught the host's website. Has any one eperienced similar issue and know how to reslove it?

Kind Regards

So, access through vSphere GUI is okay?

It's Web Access which is foo bar?

No, i cannot access it from vSphere GUI. I can access it from the host's http site but let's say when i try to see datastores i get an authentication box which then fails with th credentials i supply.

If you can login to the server locally, with the root password, it seems like the security permissions have been messed up.

Have you tried selecting Reset System Configuration? at the DCUI screen?

Personally I would either install ESXi to a USB flash drive or SD card. Once installed, this will recognise the current VMFS datastore, and then you can add the VMs to the Inventory by browsing the datastore, Right Click the VMX file and click Add to Inventory.

The current system is installed on a usb stick inside the server. Shall I remove it and intall it from another USB stick?

Okay, if you have installed ESXi on a USB stick, remove the current USB stick, and install again on a fresh good quality stick.

Sorry for being a complete noob in the ESXi USB installation world but how do I install it on a USB memory. Do I burn an iso image of ESXi installation to a CD and then boot from it and choos an option to install it on the ne USB stick?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
That is correct.

Here is the VMware KB on installing 4.1 on USB/SD:

Do i need to name the new server differently or can i use the same config details? i mean IP, name etc.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
You can use exactly the same configuration details. The VMs on the datastore, have no knowledge of the original configuration.

Also check the best practices document here

http://www.vmware.com/pdf/ws7_performance.pdf

A couple of things, only use 1 vCPU, and Reserve Memory for use with VMs.

yup. they sit on SAN.

I'm not sure if that helps but the iSCSI adapter doesn't have any targets connected

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
okay, is this an iSCSI SAN or FC SAN?

Added and Enabled iSCSI Software Initiator, VMKernel Interface?

can you vmkping the Storage if iSCSI?

if so you will need to add the new iSCSI Initiator name, to the existing LUNs.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Have you also specified the SAN IP address in the iSCSI Storage Adaptor?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
you will need to add the new iSCSI Initiator name, to the existing LUNs, on the IP SAN.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Check the following:-

1. iSCSI Initiator enabled.

2. VMKernel Interface added and IP address on same subnet as IP SAN.

3. Can you ping IP address of IP SAN from console of ESXi server.

4. Can you vmkping IP address of IP SAN from console of ESXi server.

5. Add IP address of IP SAN in iSCSI software initiator.

6. Add new iSCSI initiator name to LUNs on IP SAN.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Browse the datastore, can you see the folders?

Browse the folders, select the VMX and add Right Click and Add to Inventory?

(this is beyond the scope of original question!)
