Revert "3PAR: Provide new option to specify NSP for single path attachments"
Several issues pointed out in https://review.opendev.org/#/c/676728/ that were
not flagged here that should be fixed before we backport.
This reverts commit b7c81a7b42.

Specify NSP for FC Bootable Volume
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Given a system connected to HPE 3PAR via FC and multipath setting is
|
||||
NOT used in cinder.conf. When the user tries to create a bootable
|
||||
volume, it fails intermittently with the following error:
|
||||
Fibre Channel volume device not found
|
||||
|
||||
This happens when a zone is created using second or later target from
|
||||
3PAR backend. In this case, HPE 3PAR client code picks up first target
|
||||
to form initiator target map. This can be illustrated with below
|
||||
example.
|
||||
|
||||
Sample output of showport command:
|
||||
|
||||
``$ showport -sortcol 6``

||||
|
||||

||||

|
||||

||||
2:1:2 target ready 2FF70002AC002DB6 22120002AC002DB6 host FC 3:1:2 none
|
||||
3:1:1 target ready 2FF70002AC002DB6 23110002AC002DB6 host FC - -
|
||||
3:1:2 target ready 2FF70002AC002DB6 23120002AC002DB6 host FC 2:1:2 none
|
||||
|
||||
Suppose zone is created using targets "2:1:2" and "3:1:2" from above
|
||||
output. Then initiator target map is created using target "0:1:1" only.
|
||||
In such a case, the path is not found, and bootable volume creation fails.
|
||||
|
||||
To avoid above mentioned failure, the user can specify the target in 3PAR
|
||||
backend section of cinder.conf as follows:
|
||||
|
||||
``hpe3par_target_nsp = 3:1:2``
|
||||
|
||||
Using above mentioned nsp, respective wwn information is fetched.
|
||||
Later initiator target map is created using wwn information and
|
||||
bootable volume is created successfully.
|
||||
|
||||
Note: If above mentioned option (nsp) is not specified in cinder.conf,
|
||||
then the original flow is executed i.e first target is picked and
|
||||
bootable volume creation may fail.

This change fixes bug 1809249 - 3PAR driver picks wrong port when
|
||||
not in multipath mode. Now the user can specify target NSP (Node-
|
||||
Slot-Port) in cinder.conf. This information is used to create
|
||||
initiator target map accordingly. And then bootable volume is
|
||||
created successfully.
