Default partition allocation and job priority policy
Default partition allocation and job priority policy is defined in the FSE configuration template for FSE
partition configuration. For details, see ”Template for FSE partitions - Recall and Allocation part” on
page 305.
Definition Maximum number of drives that can be used for recall by the partition.
Impact The purpose of this parameter is to prevent the respective Partition Manager from using
all the drives at once for recall jobs. You should carefully balance resources according to
your environment.
Definition Maximum number of drives that can be used for recovery by the partition.
Impact The purpose of this parameter is to prevent the respective Partition Manager from using
all the drives at once for recovery jobs. You should carefully balance resources according
to your environment.
Definition The overall priority level for all jobs of one partition on a scale of 1 to 100.
Impact Partition priority is used together with job type priority (migration, recall, recovery,
maintenance) to calculate the initial priority of the job. With this parameter you can
differentiate overall priority of different FSE partitions.
Definition The priority for migration jobs on a scale of 1 to 100.
Impact This priority is multiplied by the partition priority in order to calculate the initial priority of
a migration job. Typically, the value of the migration priority is lower than the value of the
recall priority (because recalls are more critical than migrations); however, you need to
balance your job priorities carefully in order not to override other jobs. See ”
Priority

culation
” on page 146.
Definition The priority for recall jobs on a scale of 1 to 100.
Impact This priority is multiplied by the partition priority in order to calculate the initial priority of
a recall job. Typically, the value for the recall priority is higher than the value for the
migration priority; however, you need to balance your job priorities carefully in order not
to override other jobs. See ”

Definition The priority for recovery jobs on a scale of 1 to 100.
Impact This priority is multiplied by the partition priority in order to calculate the initial priority of
a recovery job. See ”
Priority calculation” on page 146.
Definition The priority for maintenance jobs on a scale of 1 to 100.
Impact This priority is multiplied by the partition priority in order to calculate the initial priority of
a maintenance job. See ”
