These are native capacities in MB, assuming no data compression.
The number of times this tape has been fully loaded. This parameter should
not be reset by any action of the device server.
The space currently free in the MAM. The total MAM capacity is reported in
the MAM Capacity attribute defined in
page 106
.
Note that it may not always be possible to use all the free space in a given
MAM implementation. Depending on the internal organization of the
memory and the software that controls it, fragmentation issues may mean
that certain attribute sizes might not be fully accommodated as the MAM
nears its maximum capacity.
These attributes provide a rolling history of the last four device servers in
which the tape has been loaded. The format of the attributes is as follows:
7
6
5
(MSB)
(MSB)
The same value as is returned in the SCSI
device server.
If the vendor identification is not available, the device server will
return ASCII spaces (20h).
A vendor-assigned serial number. If the product serial number is not available,
the device server will return ASCII spaces (20h).
The total number of data bytes that are transferred to or from the tape surface
(after any data compression has been applied) over the entire tape life. These
figures are cumulative and will never be reset.
These are similar to the attributes above but apply to the current load (if the tape is
currently loaded) or the last load (if the tape is currently unloaded). The device
server should reset these attributes to zero when the tape is loaded.
