Hello Experts,
When I try to create SR with lvm over iSCSI, it always failed, I list my xe
command and debug info:
[root@xcp16 log]# xe sr-create
host-uuid=a226200e-f7ff-4dee-b679-e5f114d1e465 content-type=user
name-label=shared_disk_sr shared=true device-config:target=192.168.1.2
device-config:targetIQN=iqn.2013-07.example:shareddisk
device-config:SCSIid=1IET_00010001 type=lvmoiscsi
The SR is not available [opterr=Logical Volume partition creation error
[opterr=error is 5]]
Below is log info from /var/log/SMlog:

BTW, do you know how to share the same LUN on iSCSI target server if the two
host servers are located in the different pool?
Thanks for your help in advance.
