Virtual array 7110 installation problems

jpcast_real — Thu, 19 Feb 2004 04:10:25 GMT

I am trying to install a virtual array . I want to create 2 fabrics , I have 2 storageworks switches . I follow all the steps that the installation guide says and when I try to format the array , fmt , the system does not create the LUN 0 . I have installed command view in the 2 hpux servers I have but I can not find the array :

Dartanan:/root> armdiscover

Dartanan:/root> armdsp -a

Login failed, you are not authorized to access this system.

I have seen in the manual that it may be neccesary to create the LUN 0 so I did it :

Ready > dsp -L

LUN 0:
Capacity: 1.0 MB
Number of Snapshots: 0
RGID: 1

And I also have disabled the LUN security:

Ready > secure -d

LUN Security Disabled.

But everything is the same , what can be happening:

Dartanan:/root> armdsp -a

Login failed, you are not authorized to access this system.

I include the ioscan:

Dartanan:/root> ioscan -fnC disk

Guess you should run rmsf -H on all 0/8 and 0/9 HW paths and reboot.

Yes , the problem has been solved recreating the special files and restarting hostaget... Now it is solved in one one but SDM is installed in the two nodes which access to the virtual array .. However in the second node I can not see anything .

Aramis:/opt/sanmgr/commandview/server/sbin> armdiscover
This could take several minutes ...

Failed to obtain remote database interface to host: localhost

Aramis:/opt/sanmgr/commandview/server/sbin>

Hi Javier,

The problem on second node should be linked
to Command View daemon hostagent and diald..
You could try the following procedure to manage your array properly.

On the second node:

1- Stop the daemon responsible of array management

# /opt/sanmgr/commandview/server/sbin/HA_Dial_Stop

2 - Restart the daemons

# /opt/sanmgr/commandview/server/sbin/HA_Dial_Start

3 - Run armdiscover

The result must show entries from your VA.

Hope this help!

Javier,

The message "Login failed, you are not authorized to access", very likely means you did not setup security correctly.
Run the secadmin command withing command view and add user "root" to the command view database. You could use a workaround and disable security in the panparamsconfig file.

I hope this helps,
Regards,
Jan

I had this same problem and adding the "root" user via secadmin solved the problem perfectly.

Thanks for posting this solution. Too bad the original poster didn't throw you any points.
