Below is the documented define from the SMF manual.
Your Cisize of 26K seems to be optimum for a 3390, see section 2.1.1.2
Using DEFINE to Create SMF Data Sets of z/OS V1R4.0 MVS System
Management Facilities (SMF).
I'm a bit curious as to why you would change the recommended Recordsize?
How many hours of recording does 6300 tracks give you?
DEFINE CLUSTER (NAME(SYS1.MANX) +
VOLUME(xxxxxx) +
NONINDEXED +
CYLINDERS(nn) +
REUSE +
RECORDSIZE(4086,32767) +
SPANNED +
SPEED +
CONTROLINTERVALSIZE(nnnn) +
SHAREOPTIONS(2))

Subject: SYS1.MAN allocation question
We've always allocated our SMF files as follows:
DEFINE CLUSTER( -
CONTROLINTERVALSIZE(26624) -
TRACKS(6300) -
NAME(SYS1.MAN2) -
NONINDEXED -
RECORDSIZE(26614,32767) -
REUSE -
SHAREOPTIONS(2) -
SPANNED -
SPEED -
VOLUME(SYS004) )
I'm just curious since I don't see any optimal settings in any of the
manuals for recordsize and cisize is this a good allocation?? Any help
would be appreciated. We are at z/OS 1.7.
