In addition to the status records regarding the logical volumes processed, there is a second set of records
written to the export status file that provides information about the current status of all physical volumes
in the TS7700 that have a volume state of copy-exported. The records are sorted by the percent utilized
for active data, lowest to highest. For records that have the same percentage of utilization, they are
further sorted by pool number, then volser. The table below defines the format of the physical export
volume records. DB Backup Indicator field is applied only for 8.21.x.x. or later.
This field contains the volume serial number of a physical volume,
with a volume access status of Copy Exported.
This field contains the pool the physical volume is assigned to. For
pool number 1 through 9, the value is right justified and padded
with a blank.
This field identifies the recording format used to write the physical
volume. The following values are defined for this field:
‘4’ : 3592 model J1A
‘5’ : 3592 model E05
‘6’ : 3592 model E05E (encryption)
‘7’ : 3592 model E06
‘8’ : 3592 model E06E (encryption)
‘9’ : 3952 model E07
‘A’: 3952 model E07E (encryption)
‘B’ : 3952 model E08
‘C’: 3952 model E08E (encryption)
This field contains a count of the number of megabytes written to
the volume when it was marked as full, rounded up to the nearest
MB. The value is right justified and padded with blanks. It is set to
0 when the volume no longer has any active data on it.
Note:
1. This value may be significantly less than the potential
capacity of the physical volume. When copy export is
executed, any physical volume with any amount of active
data on it in the pool being exported is marked full and
exported.
2. Starting with the TS7700 code release level R3.3, this field
expanded from bytes 15-21 to bytes 15-22. Subsequent
fields are shifted down by 1 byte.
This field reports the percentage of total active data size and total
bytes written, when the volume was marked full, that are currently
utilized for the valid logical volumes on the physical volume. Over
time, the amount of valid data on an exported physical volume will
