Drobo B1200i and vmware ESX 5.5 with two servers

Configure the second host in the same way as you did the first, make sure on the Drobo unit, you have selected more than one connection per LUN (e.g. multiple servers), you may need to add the IQN of the second server to the LUN, to allocate access.

Re-scan the iSCSI Storage adaptor, and the Datastore should appear!

Andrew just not doing something right.  Get a message "The iSCSI initiator could not establish a network connection to the target".  does that me an I don't have something setup on the DROBO correct?

I am not seeing where that is.   What am I missing?

okay do you see the LUN for the Drobo under storage devices ?

No I do not see the LUN for the Drobo under storage.

Okay, have you configured your storage network, and iSCSI correctly on this host, can you see if this host is connecting and reaching the Drobo unit ?

Ho do I do that?

Okay, you configure the host as below

HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0

HOW TO: Enable Jumbo Frames on a VMware vSphere Hypervisor (ESXi 5.0) host server using the VMware vSphere Client

samer procedure for 5.5, although I wrote these articles for 5.0!

let me know, when your hosts are configured as above, and make sure your networking and Drobo are configured for Jumbo Frames.

I have one thing that doesn't look correct on the new VMWARE server WWN is set to iqn.2005-06.com.drobo:drb1411010000059.id1 and the old one is set to iqn.1998-01.com.vmware:dwcesx1-0206c631  any clue how I get the new one looking like that?

iqn.2005-06.com.drobo:drb1411010000059.id1
iqn.1998-01.com.vmware:dwcesx1-0206c631


The iSCSI Software adaptor - WWNN is auto generated, when it's enabled

Can you obtain some screenshots ?

I got it I believe thanks andrew for all the help.
