[ipxe-devel] input/output error on iscsi sanboot from linux tgt

[yilove Gao]

Hi,
  I've got 2 Hyper-V guests; both running the current CoreOS server
test install (iso as of latest), and i'm trying to iSCSI boot
one from the other (on a CoreOS x86-64 host)

When I try to use the sanboot command on the client I do:

sanboot iscsi:172.18.14.178::::iqn.2013-15.com.example:cephrbd.target0
Could not open SAN device: Input/output error (http://ipxe.org/1d704439).

Both VMs have 1 net interfaces in 172.18.14.x; the server is 172.18.14.178.

I've already dhcp'd OK, if I change any part of the iSCSI device name
it gives a device not found error, so it's talking to the server.

  The 1st one ('master1') is running the 'tgt' iSCSI target
stack, and serves a single LUN; here is it's create command:

tgtadm --lld iscsi --mode target --op new --tid 1 --targetname
iqn.2013-15.com.example:cephtgt.target0
tgtadm --lld iscsi --mode logicalunit --op new --tid 1 --lun 1
--backing-store iscsi-image --bstype rbd
tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL

and server is started with

tgtd -f

in it's upstart script.

The tgt is happy speaking to Microsoft iSCSI Software Initiator, I can
bring up a 3rd VM and it get it

 to mount the iSCSI device and it can see it.

any suggestions are welcome.

Jim
