Description Item
Identity
The reference defined within the user environment to identify the cartridge. This is the most
useful reference for normal use as it should be visible within the application and is usually Barcode
found on a printed label on the front of the cartridge. It is different from the cartridge serial
number, which is defined at manufacture and used by HP support. Click the hyperlink on
the barcode itself to access the LTO Tape Properties window for the specific tape. See
Table 11 (page 65) .
The serial number that uniquely identifies the last cartridge loaded in the drive and which
is defined during the manufacture of that cartridge. Reference this number when contacting Serial number
HP support. It can be found on the bottom of the cartridge though it may be difficult to
read. The cartridge may also have a barcode, which is defined within the user environment
and not usable by HP support.
The data format supported by the cartridge. Format
The native (post compression) capacity of the cartridge in GB. The pre-compressed capacity
is also given assuming a 2:1 compression ratio, which is an estimate for 'typical' data. Capacity
The actual capacity of the cartridge will vary depending on the compression ratio of the
data written.
The manufacturer of the cartridge. Vendor
Configuration
Indicates whether this is a WORM cartridge - Write Once Read Many. Data written to
these cartridges cannot be overwritten or erased. WORM
Indicates whether the cartridge contains encrypted data or not. Encrypted Data
Health
The amount of tape used to write to the tape. This measurement is averaged across the
entire tape. Worst case data
(entire tape)
The amount of tape used to write high quality data to the last loaded tape. Data written by last
drive
Even if a warning is reported, the data will still have been written at high quality (unless
the drive reported an error). The warning lets you know that more tape was used to write
the data than is recommended by HP. A warning will normally trigger an alert.
If appropriate, maintenance recommendations are made, for example to clean the drive
and/or replace the tape.
Life
An assessment of whether the cartridge read/write life remaining is within specification
followed by an estimate of the remaining cartridge read/write life. Read/Write Life
Based on the amount of tape pulled over drive heads compared with HP recommended
tape life (normally expressed in terms of 'full volume equivalents' which is the volume of
data needed to completely fill a tape). If a life warning is shown, the cartridge should be
retired at the next maintenance period. HP recommends HP media for increased
load/unload life.
An estimate of the percentage of remaining read/write life of the cartridge. Based on the
amount of tape pulled over drive heads compared with HP recommended tape life (normally
expressed in terms of full volume equivalents,which is the volume of data needed to
completely fill a tape). When this figure reaches 0%, the cartridge should be retired.
An assessment of whether the cartridge load/unload life remaining is within specification
followed by an estimate of the remaining load/unload life. Load/Unload Life
Based on the number of load/unload cycles compared with HP recommendation. If a life
warning is shown, the cartridge should be retired at the next maintenance period. HP
recommends HP media for increased load/unload life.
