There are two AMA partitions on each degrowth disk pair which are in normal (available to be written to) use. If the
system AMA write pointers are within these two partitions, the degrowth procedure must be delayed until the
pointers have advanced beyond the AMA partitions on the degrowth disk pair.
AMA billing Records are accumulated on disk AMA partitions as primary AMA data. Primary data cannot be
overwritten until it is either sent to Local AMA tape (LAMA) or to the Revenue Accounting Office (RAO) via data link.
AMA data on the disks that has been written to tape or teleprocessed is called secondary data.
AMA partitions are allocated as follows:
AMA partition
MHD pair
ama,ama1
MHD0/1
ama2,ama3
MHD2/3
ama4,ama5
MHD4/5
. .
. .
ama12,ama13
MHD12/13
Dual stream billing allows each AMA partition on a disk pair to be assigned to one of two billing streams; dual and
single stream billing cannot be intermixed in the same office. In each of the two streams, data (primary or
secondary) is stored in wrap-around fashion. Offices are generally engineered to store 5 days of AMA records on
disk.
PROCEDURE
1.
Since this procedure is degrowing a pair of disks that store AMA data, the maximum amount of time to
unequip the AMA partitions in the degrowth disks may require several days to complete.

NOTE:
This step prints a list of equipped AMA partitions and stream (ST1, ST2) assignments. The two
highest-numbered partitions must be on the highest-numbered disk pair which are scheduled to be
degrown.
At the Master Control Center (MCC), type and enter:
If for Single Stream Offices:
OP:AMA:CONFIG;
If for Dual Stream Offices:
OP:AMA:CONFIG,ST1;
or
OP:AMA:CONFIG,ST2;
FOR SINGLE STREAM OFFICES:
