IP Address is incorrect (ESXi 5 Hosts) in Unisphere Manager ?

May I ask a silly question - Do you mean Host ID is different from HLU ?

Thanks

Host ID equal to HLU Value but not equal to LUN ID. Host ID and LUN ID they are both different Identifiers.

Hi,

I have followed your advice.  Once those hosts are removed from the Storage Group, all has gone (In Navisphere Manager 29)

When I attempt to reconnect host, it says "Errors encountered while retrieving information from this host".  I wonder whether it is due to vCenter intergration ?

I have removed the vCenter Intergration but finds out those Hosts are still there with the wrong IP addresses (Unisphere Manager 30)

How to disconect them ?

Thanks

To connect and disconnect a host to a storage group:

- In the tree panel, expand Storage Systems, CLARiiON Arrays, , Storage Groups.

- Right-click a storage group and select Connect/Disconnect Hosts.

- The CLARiiON Storage Group Configuration wizard – Connect/Disconnect Hosts page appears.

- To remove a host from the Hosts Connected to Storage Group table, select the host and click Remove. Only hosts in the Hosts Connected to Storage Group table are connected to the storage group when the action is executed.

- Click Finish.

When I select the HBA, I only get Reconnect OK and Help button.  There is no deregister button.

Should I pull the cable out from the Host ?  Besides, it still remembers the vCenter Information (LIke which LUN is assigned to it) ?

I have to get it done tonight.

Thanks

You need to be in engineering mode for deregistering a host from Connectivity status (Ctrl+Shift+F12 and engineering password).

I would need some time to read and research more about ESX4.x to ESX5 upgrade and issues related to it and other related informationwith whatever limited resources I have and if I found anything I will update this space at the earliest.

If there is a significant business impact due to this right now then I can only suggest to Open a Service Request with VMWare and/or EMC Technical Support. I have not received any response as such from any VMWare Guys so I am gonna read myself and see what I can update.

I have deregister those hosts.  Thanks !

Then I turn on the ESX Host and attempt to register HBA.  After typing the IP and Host Name, it says the other SP has already got that host information and then connected with the wrong IP address again *sigh*

To remove a host from the connectivity status screen, you need t oderegister each path of that host. Afterwards you can try to either let the host register itself or you do it manually.

Refer: https://community.emc.com/thread/117284

There is another strange issue is when I check the connectivity status of that Host with wrong IP address - It has ~ Management (Instead of "Host Name") !!!

Thanks

When the array sees an HBA logged in in Unisphere, it will not allow you to deregister that path until the HBA is logged off. You can go into engineering mode and see the de-register button, but that is not the correct way to de-register a host.

You should remove the host from the storage group first, then power off the host, which will log out the HBA's, then you can deregister from the Connectivty Status window.

Dear Glen,

1) We are using FC and not iSCSI

2) Yes, you are right. When we add the host to a Storage Group, it shows the name of Storage Group (Not  ~Management any more).

3) We did shutdown host, deregister HBA from Connectivity Status, turn on Hosts.  We find that

a) The 2 HBAs on the Host (each has 2 paths) are logged - Yes

b) Status is "Unknown, Fabric, Host Agent not reachable"

c) Registered - No

4) Since we are running ESXi 5 Host, there is no Navisphere Agent on those hosts.  

Your advice is sought.

Tony - you need to determine if the host agent (VMware's) is configured to use the correct IP address for the server. The IP address should be on the same subnet as the SP ports. Can you ping from the host to the SP Management Port? Can you ping from the SP port to the server?
