This analysis provides a table indicating the migration of files to the background level and the retrieval of files to the processing level.
A temporal distribution of the Recall operations (in intervals of 2 minutes) is generated. The data is supplied both for the entire Recall operation and for the individual steps of the Recall operation.

GENERAL INFORMATION | |
# MIGRATION RUNS | Number of migration runs |
# MIG FILES PER RUN | Number of files per migration run |
# RECALL RUNS | Number of (explicit and implicit) Recall operations |
# RCL FILES PER RUN | Number of files per Recall operation |
MOUNTS | Number of mount operations concerning the background level media |
MIGRATION OPERATIONS | |
# FILES | Number of migrated files |
AVG SIZE | Average size of migrated files in 2 KB pages |
AVG # EXTENTS | Average number of file extents |
MIGRATED FILES | |
# FILES | Number of files migrated between the levels S0-S1, S0-S2, S1-S2 |
# DAYS | Average number of days per file between the last access and migration |
RECALL OPERATIONS | |
# FILES | Number of files retrieved (explicitly and implicitly) from background levels S1 and S2 |
# DAYS | Average number of days per file on the background level for the Recall operation |
DURATION OF RECALL REQUESTS | |
The Recall operations are distributed across different time slots according to their duration. In the case of recall operations lasting between 0 and 18 minutes, the time slots are each of two minutes. All operations lasting longer than 18 minutes are counted in the last time slot. Both the percentages and absolute numbers of Recall operations are output. Alongside the full Recall operation (SUM), monitoring values for 4 separate steps of the Recall operation are supplied. Description of the steps: | |
SUM | Total Recall operation |
HSM0120 | From start of job to start of processing |
ARC0000 | From start of processing to ARCHIVE call |
ARC0018 | From ARCHIVE call to end of ARCHIVE |
TAPE MOUNTED | Mount operation on the background level device |
