Table 4–3 shows the incompatibilities that can exist between the three different types of
tapes that can be created on T9840A/3590 subsystems.

1 LBLK operation will result in I/O error 03. For read, an existing operator error message “DEVERR” and
an I/O error status 012 is returned to the user with fault symptom code (FSC) in sense data = 33E7.
2 LBLK operation will result in I/O error 03. For read, an existing operator error message “DEVERR” and
an I/O error status 012 is returned to the user with fault symptom code (FSC) in sense data = 33E8.
3 LBLK operation beyond 22-bit addressing will result in I/O error 03. For read, an existing operator error
message “DEVERR” and an I/O error status 012 is returned to the user. Fault symptom code (FSC) in
sense data = 338A.
• T9840A tape subsystems cannot read traditional 9-track, 18-track, 36-track, or DLT
formatted tapes. To read these tapes and transfer data to a T9840A tape subsystem,
you must have a tape device on the host system that can read 9-track, 18-track,
36-track, or DLT formatted tapes. You can then transfer the data to the T9840A tape
subsystem.
• The function of the general assign mnemonic T is expanded so that it can be used
with T9840A tape subsystems.
• Using ACS names as assign mnemonics is not supported for T9840A tape
subsystems. You should use assign mnemonic HIS98 (or absolute device assign)
when assigning T9840A tape drives. If an ACS name is specified in a tape
assignment statement, the Exec attempts to assign only 1/2-inch cartridge tape
drives (for example, HIC, HICL) available in ACS.
