SUMMARY: Sun-servers not seeing SAN-connected disks

Solution:

1) Download and install SAN Foundation Suite from http://www.sun.com/storage/san
   I used the install_it script that came with this package; very easy.
   
2) Set topology in HBA driver & disks to 'point to point'. Switch does NOT support loop.

Thanks to Andrey Borzenkov and Dave Markham!

Subject: Sun-servers not seeing SAN-connected disks

Fellow Managers, 

I am a bit of a newbie to Solaris and SANs so I need some help here...

I have a Nexsan Ataboy2 fibre connected to a Sun 280R with Solaris 9, latest 
rec. & sec. patches. Emulex LP9002 single port fibre HBA. Latest Emulex lpfc 
driver  and utility kit installed. topology=0 in /kernel/drv/lpfc.conf (loop).
Sun SAN Foundation Suite NOT installed. /kernel/drv/sd.conf updated:

name="sd" parent="lpfc" target=0 lun=0;
name="sd" parent="lpfc" target=0 lun=1;
name="sd" parent="lpfc" target=0 lun=2;
name="sd" parent="lpfc" target=0 lun=3;
name="sd" parent="lpfc" target=0 lun=4;
name="sd" parent="lpfc" target=0 lun=5;

Booted boot -r.

I want to connect an extra fiber disk to the server and I have created a simple
three port zone on my Brokade 200E SAN-switch. When connecting the server and the 
two fibre disk arrays to the switch, the switch sees all WWNs and report valid 
info for all these. However, the 280R does not see any disks. boot -r done. The 
zone is a private zone and I'm almost certain that this is set up correctly (it
works fine if I connect two Win2003 servers and an other Ataboy2x to an identically
configured zone).

The output below is generaten on the 280R with the Ataboy2x disk array directly
connected.

I have another Sun-server (SunFire V240) with a QLogic fibre HBA. Solaris 9 with 
latest patches. If I try to connect the disk to the server using the SAN-switch,
the same thing happens.

Suggestions will be greatly appreciated.

I will summarize.

Thanks!


Best regards,

Nils
