Column number
Represented as Cy, where C equals the column and y equals its number.
Columns 1 - 4 are available for drives, however if the frame is in position 1
(the leftmost frame of the library) only columns 2 - 4 are available.
Row number
Represented as Rz, where R equals the row and z equals its number. Rows
1 - 4 are available for drives. Regardless of whether drives are installed, the
row numbering is the same for every frame.
The physical address of all drives is displayed in the Location column of the
Drives table. The Location column is displayed by default.
Logical addresses
The TS4500 tape library assigns each drive a SCSI element address that consists of
a value that defines a logical location in the library to the SCSI interface. This
logical address is represented as xxxx(yyyh), where xxxx is a decimal value and
yyyh is a hexadecimal value. It is assigned and used by the application when the
server processes SCSI commands. The SCSI element address for a drive is unique
to the location of the drive; it does not vary based on other drives in the library.
The logical address of all drives is displayed in the Element address column of the
Drives table. The Element Address column is hidden by default.
Control path drives
A control path is a logical path to the TS4500 tape library.
A control path is the path for SCSI Medium Changer commands sent by a server
to control a specific logical library. The TS4500 tape library has no direct SCSI
connection to a server. When a server communicates with the library, it sends the
communication by way of an LTO or 3592 tape drive. The LTO or 3592 tape drive
is designated as a control path.
Methods of cleaning drives
Automatic cleaning of tape drives is enabled by default in the TS4500 tape library.
However, it is also possible to initiate manual or host cleaning.
Notes:
v It is the operator's responsibility to monitor cleaning cartridge usage.
v Automatic cleaning is always enabled with the Advanced Library Management
System (ALMS).
The head of every tape drive in the tape library must be kept clean to prevent
errors that are caused by contamination. To help you keep the drives clean, IBM
provides a cleaning cartridge with the library. Whenever a drive determines that it
needs to be cleaned, it alerts you with a message on the library's display or host
console. The library uses the cleaning cartridge to clean the drive with whatever
cleaning method that you choose. In all methods, cleaning is performed after the
data cartridge is unloaded from the drive and before the next load.
It is the operator’s responsibility to monitor cleaning cartridge usage and replace
cleaning cartridges as necessary. The TS4500 tape library provides multiple ways to
monitor and manage cleaning cartridges. If SNMP traps are enabled, a trap is
generated when a cleaning cartridge expires. It is also possible to use the TS4500
