trying to connect a drobo to a VMWare ESXi 4.1 host, im following guide: http://www.drobo.com/pdf/DroboElite_VMware_Best_Practices.pdf
on page 20 of the guide i have a problem, it says, "The LUN id matches the Volume id when you created in Drobo Dashboard above"  i did not see a LUN id, on this probo there is production data so i can not acidently format a wrong lun, that would be terible.  using the drobo dashboard i can not find a way to view the LUN id for the unformated LUN i just created. here are some version numbers:

drobo dashboard: 1.6.8
DroboElite Firmware: 1.0.2

any advice on how to make sure i use iscsi to connect the correct LUN to my VM host would be great.

thank you

hi Marek,

pls confirm if you are trying to attach the  LUN to the ESXi box or adding it to a VM as a RDM. If you are adding this to the ESXi host then you will see the ID shown in Drobo elite console on the ESX datastore screen.

However, if you are trying to add that to the VM then the ID on the VM will be different.

Can you post a screen shot of your Drobo panel and screenshot of ESXihost>>configuration>>Storage Adapters...

i am attaching the LUN to the ESXi server as a data sotre, i do see the LUN ID on the ESXi server, i do not know how to see it on the drobo dash board.  this is what i did as a temp work around, on the drobo i created a 1TB LUN (this is the only 1 TB LUN on the drobo), then on the ESXi server i saw the 1 TB LUN ID is 17.  so, i then created another LUN (the 2 TB that i needed) and when i went to the ESXi server, i knew the LUN ID would be 18, and thats the LUN i attached.

what i did worked in the current situation.  but i would still like to know how to find the LUN ID on the Drobo Dash board, or some way to match the IDs up with the LUNs i see listed on the dashboard.

hi Marek,

page no.12 section 12 has a screen shot of the drobo console where it shows the ID, this is the same ID that you will see in ESX console.

In case of the example used in the pdf the id 49 is in redbox and when you lookup for id on ESX it shows with iqnxxxxxxxx.id49

i do not have a Drobo console at this point so could not post any screenshots.

hi marek,

to add further to your last comment,the lack of console made me look at the available screenshots better.....technology is so baffling that at times we miss out things under the hood....you are not alone on this...there were many a time when i landed up in such spot....

happy reseraching....
