VA7100

I have a VA7100 with two controllers that I wish to access from two hosts, an L2000 and an N4000 running HP-UX 11.00, one on each controller. The plan is to create two luns, each allocated to just one host each and not accessible by the other host.
I've tried loading CVSDM on each host. This works fine on the L2000 but when I load it on the N4000 it hangs on the final part of the installation(armdiscover).
I am able to see and configure the luns I have created(using the L2000) from both hosts but not able to allocate one lun to each host.
When I run CV from the L2000 and try to 'discover hosts' it will only return the local host. I've tried many combinations to no avail, always the same result.
Is what I am attempting feasible on a VA7100(the manuals seem to indicate it is but gives no details) and if so where am I going wrong?

Re: VA7100

Hi,

if you want to "hide" certain LUNs from certain hosts (or rather WWNs of FC HBAs) you need a "Secure Mangager" license. It think it comes in slices of 500GB, the default licence of Secure Manager can only handle 50GB.

run
# armfeature -r
to find out what license you have

If you do not have that capability all hosts will see all LUNs.

Re: VA7100

You need not load Command View SDM on multiple hosts. You can install it on one host and configure the array. And the LUNs will be visible to all the hosts. And for securing that as Bernhard suggested you need Secure Manager VA license. I guess you need to send the array serial number to hp for obtaining the license key.

Thanks for a quick response

This is the output from the armfeature command:

FEATURE LICENSE KEY STATE

Re: VA7100

This sounds good. So you should be able to "secure" your LUNs.

Guess the easiest way would be you run launcher on the L2000 and use the GUI.

If you cannot use the GUI, carefully read:
man armsecure

fcmsutil /dev/td# gives you the WWNs of the FC HBAs of your hosts.

Then you build a table like that
DEFAULT 0 WC
NODEWWN 50060b000012aa5b 1 W
NODEWWN 50060b000012a909 1 W
NODEWWN 50060b000014a349 2 W
NODEWWN 50060b000014abe5 2 W
DEFAULT 1 0
DEFAULT 2 0

3rd col is LUN #, 4th is permission:
Write/Write-config/None

then you apply this table like
armfeature -w -c -f -p AUTORAID

*After* that run ioscan -fnCdisk; insf -e
on two HBAs you will see LUN1 on the other two you see LUN2.

Bernhard and Karthik

Excellent. Thanks for your help. All is working as I had hoped.
(note: armfeature s/b armsecure)
