IGD17334I

Explanation
This is a failure message issued by SMS. The copy
operation specified ‘required’ fast replication, but SMS
was not able to match the stripe count of the  target data set with
the stripe count of the source. Note that,  in general, if the stripe
count of the target data set is different than the stripe count of
the source data set, then this represents a fundamental conflict between
striping  requirements and fast replication requirements. In situations
where this occurs, fast replication will not be possible. Allocation
was failed.    
In the message text: dsn
Data set name
var1
Stripe count computed by SMS for the data set being allocated
var2
Stripe count of the source data set passed in by the caller

System action
Processing stops.

System programmer response
If ‘fast replication’
is necessary, then you must ensure  that the candidate Storage Groups
have an exact number of eligible fast replication volumes to match
the stripe count of the source data set.

Programmer response
You may change the copy request from ‘require’
fast  replication to ‘prefer’ fast replication. If ‘fast
replication’ is necessary, then you must ensure that the candidate
Storage Groups have an exact number of eligible fast replication volumes
to  match the stripe count of the source data set.
