Ok, now it at least visible what happens.
next step: look to the /var/log/SMlog after sr-probe.
PS Please, reply to maillist, i'm not a personal support
service.

As
for software iSCSI â I can easily fire it up through
XenCenter with multipathing and all the stuff I need, but
using HBA capabilities is quite critical to me. If it may
help, the device I use is HP StorageWorks P2000 G3 with 4
1Gbit Ethernet storage ports per controller. The wiring is
OK, I doublechecked it. Also I even tried to connect the
storage directly to the servers to get rid of possible
failure point at the switch.
Â
Well, may be output of the xe sr-create
should be attached? Guessing 'what is wrong' is kinda useless
activity without logs or command output.

Certainly.
And lvmoiscsi works fine. I need to fire it up as lvmohba,
which causes troubles.

Did you try to performs xe sr-create with
type=lvmoiscsi?
05.12.2012 14:45, Yatsko Mykhailo ÐÐÑÐÑ:
Hi everyone.
I am a complete newbie
to Xen. I run the following config:
HP ProLiant DL360 G7
server, 2 absolutely identical items, running latest XCP.
They are joined in a pool. Also there is a HP StorageWorks
P2000 G3 storage array. This is the config I have troubles
with.
Currently we are
planning to migrate to Xen-based solutions from
VMWare-based. We have other 2 servers (also identical to
those mentioned above), which make use of the same storage
device. VMWare servers connect to the storage over HBA.
XCP ones do not
recognize LUNs (though there is one made specially for
them and not in use by any other machine) when adding a
HBA storage, but work fine if adding it as software iSCSI.
ÂThere are no restrictions as for access at the storage
side, no passwords etc.
Any piece of advice
would be highly appreciated.
