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.

Well, I canât even probe the device.
xe sr-probe type=lvmohba returns
Error code: SR_BACKEND_FAILURE_107
Error parameters: , The SCSIid parameter is missing or incorrect, <?xml version="1.0" ?>
If I set the SCSIid - xe sr-probe type=lvmohba device-config:SCSIid=*****
Error code: SR_BACKEND_FAILURE_1
Error parameters: , Error reporting error, unknown key Device not appeared yet,
And xe sr-create shared=true type=lvmohba name-label=LUN9 device-config:SCSIid=**** returns the same

Error parameters: , Error reporting error, unknown key Device not appeared yet,
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.
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?

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. There are no restrictions as for access at the storage side, no passwords etc.
Any piece of advice would be highly appreciated.
