To select a row, click on it with the mouse; the selection will be highlighted. Note that when you select a
row, you are selecting a storage class within a particular storage subsystem.
See also the related window Configured Storage Classes, described in Section 6.1.1 on page 157. The
Configured Storage Classes window lists all configured storage classes in the system, whether or not any
storage resources have been assigned to them.
Field Descriptions
Active Storage Classes list
The Column View menu item may be used to determine which of the following columns are displayed in
the list;
Subsystem. The name of the storage subsystem to which the storage class information applies. It is
possible to have multiple rows in the table with identical storage class ID and Name columns, each for a
different storage subsystem.
ID. The unique storage class ID number defined when the storage class is configured.
Name. The name of the storage class.
Type. The storage class type; possible values are "Disk" or "Tape".
Thresh. The current threshold status for the storage class. For disk, a threshold is defined as a percentage
of the total bytes of storage space. When the percentage of storage space used rises above a threshold
level, the threshold is exceeded. For tape, a threshold is defined as a count of free virtual volumes. When
the number of free volumes drops below a threshold level, the threshold is exceeded. Possible values are:
• OK - The storage class has not reached its warning threshold.
• Stale - The storage class is active but the MPS responsible for it is shutdown, has died, or is
otherwise inaccessible to SSM.
• Warning - The storage class has reached its warning threshold, but has not reached its critical
threshold.
• Critical - The storage class has reached its critical threshold.
Free Space. The amount of free space left in the storage class. For disk, this is the number of free bytes.
For tape, it is the number of free virtual volumes.
% Free. The Free Space value expressed as a percentage of Total Space.
Used Space. The amount of used space in the storage class. For disk, this is the number of used bytes.
For tape, it is the number of used virtual volumes.
% Used. The Used Space value expressed as a percentage of Total Space.
Partially Filled VVs. The number of tapes that have been written, but have not yet reached EOM. This
field will be blank for disk storage classes.
Total Space. The total amount of space in the storage class. For disk, this is the number of bytes. For
tape, it is the number of virtual volumes.
Migr State. The migration state for the storage class. The Purge State resets to WAITING or NONE as
