LLA refresh would stop the logon ?? Under what circumstances it can happen
? Where there any modules copied to the linklist which was in steplib of
tso logon and that caused some program errors ? During the logon time there
should be some error message in the log. Can you post that here ?

As others have pointed out, please post messages for this issue.
Did the users who could not logon get CSV message? If so, post the entire
message and text.
If ATOPCEED is a started Task, you should be able to view the JOBLOG for the
STC and see what it does.

It would need to purge the pipeline, wouldn't it?
I would think that all the operand addresses for instructions in the pipeline
would need to be recalculated. And I suspect it might affect instruction
interlocks and out-of-order instruction execution, too.

All I can say is WOW, also. There are only two reasons I can think of to have
it cost that much. 1) It is a milli-code instruction, or 2) It purges the
pipeline.
If that time is for each instruction, then I tend to think it is milli-code.
If the time is for a SAM64/SAM31 pair, then I think it

Thanks very much for this. Really I don´t guess about to read 2721 as
hexa number but a normal number since it isn´t in x'' or 0x.
0d0b is clear that is hexa number but 2721 isn´t. Any way thanks again.

You cannot do a full volume restore, so stated in the messages manual.
What you can safely do is a selective data set restore.
If you want to live dangerously, you could restore by track address.

If this was a logical dump, you could restore the individual datasets. Execute
the restore job with PARM='TYPRUN=NORUN' to get a list of the individual
datasets.
If this is a physical dump, you have no choice. You *MUST* provide at least
a 3390-9 to restore successfully.

It appears you are trying to restore a 3390 mod 9 to a 3390 mod 3. The 2721 you
have listed below is hex for 10,017 which is the number of cylinders in a mod
9. In order to do a full volume restore your target volume will also need to be
