Optional remote support is available for the TS3500 Tape Library through its Call Home 
capability. The Call Home feature uses a modem connection or a system console to report 
failures that are detected by the library or a tape drive. Whenever a failure is detected, Call 
Home sends detailed error information to IBM (home). The IBM Service Representative can 
then prepare an action plan to handle the problem before traveling to the library. The 
library may also periodically send support information (such as configuration, library and 
drive code versions, and error logs) to IBM.
The Call Home feature of the TS3500 Tape Library has three different, but related, 
capabilities: Problem Call Home, Heartbeat Call Home, and Test Call Home. The TS3500 
Tape Library sends data files that may be helpful to Support Center personnel for all three 
types of Call Home. These data files include library error logs and configuration information, 
such as the Machine Reported Product Data (MRPD) log. The MRPD file contains information 
about the machine (library), including the number of frames and drives, the model and 
serial number of each frame, the type and serial number of each drive, the code version of 
the library and each drive, and any machine-detectable features such as additional I/O 
stations, capacity expansion, and so forth. In the case of a Problem Call Home, the library 
also sends any trace files that are related to the problem. 
Problem Call Home
The TS3500 Tape Library or one of its drives detects a problem and the library 
performs a Call Home operation to create a Problem Management Record (PMR) in 
the IBM Remote Technical Assistance Information Network (RETAIN). This is a single 
page of text data that enables the Support Center or the Service Representative to 
access an action plan and a list of parts (called field replaceable units or FRUs). 
Heartbeat Call Home
The TS3500 Tape Library sends the Heartbeat Call Home on a scheduled basis in 
order to ensure proper Call Home functionality. By default, the Heartbeat Call Home 
is sent once per week, one hour after a power cycle, and one hour after a code 
update is complete.
Test Call Home
When servicing the library, the Service Representative can issue a Test Call Home 
operation to RETAIN from the library's operator panel. The library allows the Service 
Representative to include drive dumps in the Test Call Home for analysis, rather than 
collect dumps by using CETool and transmitting them through an IBM messaging 
system. In this way, a drive dump can be accessed by Support Center personnel 
through the Call Home database.
