TapeAlert Logs
You can retrieve TapeAlert log information through one of three methods:
Operator Control Panel (OCP)
Remote Management Unit (RMU) display to screen
Detailed logs saved to text file through the RMU for call center diagnosis
Further information and recommended actions for tape drive TapeAlerts can be found in Table 3 .
TapeAlert Logs through OCP
To view TapeAlert log information from the front panel:
1. From the front panel LCD, scroll to Diagnostics, and then press Enter. The Diagnostics submenu appears.
2. From the Diagnostics submenu, scroll to TapeAlert Logs, and then press Enter. The TapeAlert log information is
displayed.
3. You may scroll up and down through the TapeAlert log entries. The most recent entry will be associated with the
highest event number shown.
Within each TapeAlert log entry, you may scroll up and down to display the date and time that an error occurred, the barcode
label associated with the tape being used at the time of error (if barcode labels are being used and the barcode reader is
enabled), and any TapeAlert flags set during that event.
TapeAlert Interpretation
In order to display any combination of TapeAlerts that may be set for any one event, a binary representation is used. The 16
character hexadecimal TapeAlert representation is broken down into a total of 64 bits (16 x 4 = 64), one for each possible
TapeAlert that may be reported. The illustration below demonstrates TapeAlert bit assignment, as well as practical examples.
In the first example, the tape drive requested cleaning. In the second example, cleaning was attempted with an invalid
cleaning cartridge.
NOTE: The binary representation for every possible TapeAlert is presented in Table 3 . Multiple TapeAlerts may be set as
shown in the following example:
