Field Descriptions
Storage Class Update Interval (seconds).
The interval that indicates how often the MPS will query the
Core Server in its subsystem to get the latest storage class statistics. This is also the interval the MPS
uses to check whether it needs to initiate a purge operation on the storage class based on the associated
purge policy. The valid range for this field is 10-600.
Maximum Volumes for Whole File Migration.
The maximum number of tape virtual volumes that will
be mounted for any tape storage class using the Migrate Volumes and Whole Files option. Migration of
other storage classes, end user stage requests, and many other factors should be considered when
deciding on this value.
Core Server API Failures Allowed.
The maximum number of consecutive Core Server API failures
allowed before MPS aborts a migration or purge run. This applies to both disk and tape migration as well
as disk purge. If this limit is reached during a disk migration run, migration skips to the next hierarchy to
which that disk storage class belongs. Once the run has attempted to migrate all such hierarchies the run
will end. If this limit is reached during a disk purge or tape migration run, the migration or purge run
aborts.
MPS Report File Name (path/prefix)
. A prefix string used by the MPS to construct a migration report
file name. The full file name will consist of this string with a date string and subsystem ID appended to
it. If this field is left blank, no migration reports will be generated. If a usable path prefix is not specified,
the location of the migration report files may be unpredictable. A new MPS report file is started every 24
hours.
5.1.3. Mover Specific Configuration
5.1.3.1. Mover Specific Configuration Window
This tab of the
Mover Configuration
window allows you to update and view the type-specific
configuration for the Mover.
The server must be recycled in order for changes to become effective.
The Mover cannot be configured entirely from the SSM window. See Section 5.1.3.1:
Additional Mover
Configuration
on page 104, for further necessary configuration.
Field Descriptions
Encryption Key.
An encryption key used to secure the Mover's interface with the Core Server. A
specific value may be entered in the field or a random value may be generated by clicking on the
Generate
button. The default value is 0. A non-zero value must be configured to allow client access to
the Mover’s data interface. See Section 5.1.3.1:
Additional Mover Configuration
on page 104, for further
information about the encryption key.
Buffer Size.
The buffer size used for double buffering during data transfers. The default buffer size is set
to 1,048,576 bytes (1 MB). This value should be tuned based on device and networking configuration
