Hi,
thanks this problen i could fix with the help of a colleague. the
missing piece was "devfsadm -Cv" - reconfiguring the new devices.
if you have any idea about npiv that would be great.
There should be error messages in
/var/log/xen/xpvd-event.log
From these, what failed exactly?

Hi,
i'm having problems attaching disks from a fc-san to a solaris
10 guest.
xen host ist a opensolaris box "SunOS node1 5.11 snv_127 i86pc
i386 i86xpv".
my xen guest is named pg4.
this command works fine.
virsh attach-disk pg4
/dev/dsk/c8t600A0B800029D69A000013CA4B00E1ABd0 hdb
Really? You should have to supply p0, i.e. cXtYd0p0
This should work.
virsh attach-disk pg4
/dev/dsk/c8t600A0B800029D69A000013CA4B00E1ABd0p0 hdb
and before i was able to import this volume as a zpool on the
xen host - so connection to this volume looks fine.
when i run format i only see the file-based disk:
global: r...@pg4:~ > format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0d0 <DEFAULT cyl 4092 alt 2 hd 128 sec 32>

Specify disk (enter its number): ^C
zsh: 1777 exit 1 format
this is the configuration of the guest:

in /dev/dsk i also only see this one file based disk.
Can you help me with this?
The second option i found useful and but bad documented is npiv.
I create a virtual port for the 2 fc-hbas in the machine via
fcadm create-npiv-port -p 2000000000000001 -n 2100000000000001
2100001b321fbc18 fcadm create-npiv-port -p 2000000000000002
-n 2100000000000002 210000e08b947697 and the result looks fine:
global: r...@node1:~ > fcinfo hba-port

Now attaching this to the guest according to
http://www.mail-archive.com/[email protected]/msg05181.html
fails.
virsh attach-disk pg4
/2100001b321fbc18/2000000000000001/3000000000000001/12 hdb
--driver phy --subdriver npiv
what's wrong?
There should be error messages in
/var/log/xen/xpvd-event.log
From these, what failed exactly?
