Your step number 2 is not exactly true, it won't wait for migration to empty
space.  If you are setup for client to go directly to tape, it will do that
IF tape mounts etc are available.

And your last question is correct - it is terminated.  Simplest solution
is to increase diskpool or if that's not an option,  adjust schedules to
update migration percentages so pool will be emptier when this
clients schedule comes around.  (I've done a good bit of this "tuning".)

Environment:  TSM OS/390 server - V4.1.4      Linux Client - V4.1.4

Been trying to archive a client node. The archive disk pool is not as
large as the amount of data to be archived.

Received a "failure" on the archive. This is one of the messages:

05/16/2002 10:43:20 ANS1228E Sending of object
'/usr/local/blackboard/docs/courses/1/INFO-360-002-2002Spring/content/_65742_1/360web_ontime2.zip'
failed

I looked into the server log and found the related message:

05/16/2002 10:43:01   ANR0534W Transaction failed for session 62 for node
ATHENA.VCU.EDU (Linux86) - size estimate exceeded and server is unable to
obtain additional space in storage pool SPARCHIVE.
Yes, I looked up the ANR0534W message. It talks about both a possible
COMPRESSION issue as well as insufficient space in the storage pool.

Yep, the compression for this session was "-5%".

So......Big deal.....I would not think this would/should cause a permanent
failure and lack of archiving of the file in question.

Yes, I realize the storagepool filled up.  My understand has always been,
and please correct me if I am wrong, that is a storagepool fills
up/reaches the HI value, 2 things occur:

1.  Migration is kicked off, moving data to the defined NEXTPOOL (which is
did)
2.  The CLIENT is told to "Whoa......Stop Sending Data......Hang on while
I move stuff out of the storagepool to make more room....OK Client, you
can send me more data, now......"

Am I way off on this or is this some sort of problem ?

Also, the book says : "System Action: The specified session is ended and
server operation continues."     Does this mean the archive was killed and
did not finish successfully ?
