All other avenues have been tried and discarded, and the remaining possibility is to use the advanced security features on Cisco fabrics allowing for LUN's to be only presented to specific hba's - so the idea is to mask LUN 0 from all but the hba's in the CV server.
The environment is all windows.
It's clear that NT 4 needed to see LUN 0 to then be able to discover data LUN's on the target - but does anyone know if in Windows 2000 and 2003 are the same? I am reasonably sure that W2003 is SCSI-3 compliant which knows LUN 0 is assigned to the controller for management only - but in general, if LUN 0 is masked - can W2000 and 2003 go on to discover and use data LUNs on the EVA?
Solved! Go to Solution.

SolutionWould password-protecting the HSV controllers be a valid workaround?
You can assign an 8 character password through the HSV's OPC and on Command-View EVA.

Re: Mask EVA LUN 0 (CCL) at Cisco fabric level
Can you ask the guys in CXO to implement a manager access similar to what appeared on the HSG? Access to the controllers is granted through the WWPN.
Of course, you need an emergency fallback through the OPC or the serial maintenance port in case you lock-out your last CV-EVA server!

Re: Mask EVA LUN 0 (CCL) at Cisco fabric level
There will be a total of 54 internet facing servers through the lifetime of the solution, so although asking could be a short term fix for phase 1, it looks clear (assuming I've read this right) that the customer is going to look to 3rd party storage now as an XP is out of budget. :(

Re: Mask EVA LUN 0 (CCL) at Cisco fabric level
I would guess it means the Host level LUN, which is assigned when you present the Vdisk. For each host, it starts the LUN numbering at 1, and then counts up (unless you manually select one). So, if what Uwe is saying is correct (and it usually is!), each host could have up to 7 Vdisks presented.
Regards,
Stephen

You can map 7 virtual disks to one host's LUN addresses 1..7 and then you can map 7 *other* virtual disks to a second host's LUN addresses 1..7.
