Virtual TapeServer 6.04.04 for NonStop Servers Operations and Administration Guide

72 | Using Scan/Cleanup
Here is a description of the status tables, fields, and buttons on this page:
Status table
This table lists all virtual tapes on the system and their Scan/Cleanup status. The following is
a description of each column:
Pool :: Cartridge
Displays the name of the pool and virtual tape.
Erased
Displays the timestamp when the virtual tape was erased.
Written
Displays the timestamp when data was last written to the virtual tape.
Retention
Specifies how long the virtual tape will be retained. A retention period specifies an
expiration date and time, which governs when vault space can be reclaimed.
Migrated
Displays the timestamp when the virtual tape was backed up (typically to physical
tape) by a backup management application. If the virtual tape was migrated by
another application, n/a or not by VTS is displayed.
Size Displays the size of the virtual tape (in bytes). This reflects the size of the tape data; it
excludes the size of the metadata (up to 27MB).
Erase Indicates whether the virtual tape is selected for erasure or not. This column also
provides an explanation of the business rule that is controlling the erasure status.
In the following example, virtual tape X00001 was erased on 13Feb05 15:43, last written on
17Feb05 14:49, will be retained for two weeks, and has never been migrated. The business
rules indicate “no, not past retention,” which means the virtual tape is not scheduled for
erasure because it is not past the retention time.
In the following example, there are two virtual tapes, N00014 and N00015, which were erased
on 13Feb05 15:43 and last written on 17Feb05 14:49. Their retention time is 2 weeks and they
never have been migrated by VTS. However, the user has elected to override the business
rules and has indicated that N00014 is to be erased and that N00015 will not be erased.
