sam-catserverd - Oracle HSM media manager daemon
∕opt∕SUNWsamfs∕sbin∕sam-catserverd
SUNWsamfs
The sam-catserverd daemon keeps track of media in Oracle HSM
library catalogs. A library catalog is the central
repository of all information needed by the Oracle HSM environments
to find cartridges in an automated
library. The library catalog file is a binary, UFS-resident
file that contains information about each slot in a library or
manual drive. The information in the catalog includes the
Volume Serial Name (VSN), the capacity and space remaining, and the
flags indicating the status of the VSN.
When the sam-catserverd daemon starts, it checks for
the presence of a catalog file
for each automated library defined in the mcf file.
If a file is not found,
the sam-catserverd daemon creates a library catalog file
in the default
location, ∕var∕opt∕SUNWsamfs∕catalog∕family_set_name.
The family set name is used for
the catalog file name.
Alternatively, a file can be specified by
the user in the Additional Parameters field on the library definition
line in the mcf file.
If the automated library is SCSI attached, the library catalog is a one-to-one mapping between the library catalog entries and physical slots in the automated library. However, if the automated library is network-attached, the library catalog is not a direct mapping to the slots, but it is a list of VSNs known to be present in the automated library.
The library catalog contains the following information about each VSN in the library:
Status bits
Media type
Volume serial number
Storage slot
Partition
Count of access
Capacity of volume
Space left on volume
Block size or sector size for optical media
Label time
Last modification time
Last mount time
Bar Code
First word address of PTOC (for optical media) or last position found (for tape media).
If reserved VSNs are used, the following fields are also present:
Time reservation made
Archive set
Owner
File system
