It works fine for me...

Subject: CP Directory, profiles, and COMMAND: Could someone verify this for 
me...



We started with vSwitch grants in SYSTEM CONFIG, then moved to reading lists of 
Linux guests and dynamically granting them to the vSwitch. We then switched (no 
pun inteneded) to COMMAND statements in each CP Directory to grant the vSwitch 
and couple the NIC to the vSwitch. This seemed to be the most consistent and 
least intrusive method of emulating an open vSwitch, and reduced the need for 
adding users or config lines to other files.

Except for one slight drawback: If the two COMMAND lines are in the user's CP 
Directory entry, then the grant is done, followed by the couple, and everything 
is happy. If the same two COMMAND lines are in a profile, included in the 
user's CP Directory entry, then it appears that either the commands are 
executed in the wrong order, the grant never gets executed, the grant executes 
but with the wrong or no userid, or the system doesn't allow the grant to 
complete before attempting the couple. In any case, the user does not get a 
working NIC coupled to the vSwitch.

Could someone verify this behavior on their system? I'm getting ready to open 
an ETR with IBM, but I'd like verification that I'm not overlooking something 
else...

The minimal entries needed to recreate this are:

TSTDFLT DIRECT:

PROFILE TSTDFLT
COMMAND SET VSWITCH VSWG GRANT &USERID
COMMAND COUPLE 8200 TO SYSTEM VSWG
*
MACH XA
CONSOLE 0009 3215 T
NICDEF 8200 TYPE QDIO LAN SYSTEM VSWG

-----
TESTUSER DIRECT:

USER TESTUSER XXXXXXXX 1G 2G G
INCLUDE TSTDFLT
*
*
*  COMMAND SET VSWITCH VSWG GRANT &USERID
*  COMMAND COUPLE 8200 TO SYSTEM VSWG
*
*  CONSOLE 0009 3215 T
* NICDEF 8200 TYPE QDIO LAN SYSTEM VSWG

Try them this way; The user seems to never get granted. Then comment out the 
INCLUDE and uncomment the other four lines. The user gets granted the first 
attempt.

Any comments or ideas?
