[Bug 1238169] Re: 13.04 server: Fujitsu BX900/DX90 installation problem

[Andy Igoshin]

MULTIPATH

multipath works immediately and as expected. there are no any claims
to multipath itself (except Bug #1240047, Bug #1240049).

problems are begun if you configure more than one initiator for one
physical Emulex CNA interface. obviously this problem relates not only
to multipath but in general to large quantity of initiators configured
in Emulex CNA BIOS.

the cause of this problem is open-iscsi.
'iscsiadm -m fw' will show only some initiators configured in
Emulex CNA BIOS - only one for each physical interface.
'iscsiadm -m discovery -t fw' will return the same implicitly.

further it is more upsetting.

'iscsiadm -m discovery -t fw' or 'iscsiadm -m discovery -t st ...'
(each one separately) can't build working base of nodes.
it gets confused in multipath and generates wild mishmash of
initiators, targets and paths. please note that some of such paths are
incorrect and do not lead to corresponding targets.
so it is impossible to fully automate the definition of nodes, instead
it is required to edit /etc/iscsi/nodes and /etc/iscsi/send_targets
manually.

Title:
  13.04 server: Fujitsu BX900/DX90 installation problem

Status in “open-iscsi” package in Ubuntu:
  New

Bug description:
  i try to install ubuntu 13.10 server on Fujitsu BX900 (BX924S3
  diskless blade) whose storage is Fujitsu DX90 iSCSI target (iSCSI
  boot).

  in the BX924S3 blade Emulex CNA 10G adapter is used. this device has
  hardware iSCSI support. i configure iSCSI initiators on it. after that
  corresponding LUNs become visible in the BX924S3 blade's BIOS.

  ubuntu installer does not detect LUNs available in such a way. i think
  its "Detect disks/login to iSCSI target" functionality supposes
  starting of software iSCSI initiator in the OS instead of detecting
  and working with LUNs connected via Emulex CNA adapter.

  at the same time system successfully detects the presence of Emulex
  CNA adapter. also in the OS i see loaded components be2iscsi/*.

  SLES 11 SP3 and CentOS 6.4 successfully detect such hardware
  configuration. they are installed, run and work (i have corresponding
  dmesg and lsmod).

  are there any chances that this hardware configuration will also work
  in ubuntu in the nearest future?

  Regards, Andy
