EVA3000 HP-UX without Secure Path

benoit Bruckert — Thu, 23 Jun 2005 03:57:13 GMT

Hi,
I have a developpement server I would like to connect to the SAN (switched/zoned EVA3000).
My question is : Do i need Secure Path on the dev server ? I have absolutly no requirement concerning security about the connection.
Does I need a specific driver to access the LUNs i will create ?
The dev server is HP-UX 11.11

You can make a single path connection if you don't want/need to use Secure Path.

Without Secure Path, you don't need an additional special driver, because there is no failover involved, but you need to check the EVA release notes for any operating system patches and adapter driver versions.

You need to create a zone with one FP port of the EVA3000 and one controller off your HP9000.

With multiple connections you NEED securepath to have a stable environment

thanks for your reply,
I tried to connect, link is OK,
I created a zone with only 1 FP and 1 HBA
I created a lun that i exported to the dev server,
After installing latest support bundles, I can see some component through ioscan :
here is an extract of the interested part :

fc 1 1/12/0/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
/dev/td1
fcp 1 1/12/0/0.1 fcp CLAIMED INTERFACE FCP Domain

ctl 38 1/12/0/0.1.6.255.0.0.0 sctl CLAIMED DEVICE HP HSV100
/dev/rscsi/c8t0d0

The question I have now :
Where is the LUN ??
What are the c8t0d0 and the c7t0d0 ??
I didn't find any specs or releases note about this kind of configuration . Does anybody have any idea ?

/dev/rscsi/cxtydz are the HSV controllers.
I don't see any disk.

Can you try
ioscan -fnC disk and look for an output
DEVICE HSV100

Most of the disk come from an JBOD bay of disks, connected to a second HBA (td0).
I have no "DEVICE HSV100" ! Nothong connected to td1 (1/12/...).
Why does I see 2 controllers, as just one is linked through the zoning ? I should see just One ???

Benoit,
I am having the EXACT same problem. Were you ever able to solve it? If so how?

Thanks.

Can you please check if you registered the correct hba/wwn within commandview? And second, please verify if you choose the correct host os type.

regards,
Bernd
