IBM 3590 - Manual (Page 95)

Replacement of the leader block is a temporary repair. It allows the operator
to insert the cartridge, with the file-protect selector (see item
3 ) set to the
file-protect position, once. This, in turn, allows the data to be copied to a new
cartridge. After you repair the leader block and recover the data, do not use
the cartridge again.

Unloading a Tape Cartridge after a Power Failure
The normal tape subsystem process will unload a tape cartridge as soon as
power is restored to the device. An exception occurs with a FID 1 condition. If
the device fails to unload a tape cartridge after a power failure, select Unload
Drive on the operator panel and press Enter:
v If the drive unloads the cartridge, remove it by grasping the finger notch
(see item
4 in Figure 16 on page 67).
v If the drive does not unload the cartridge and a FID or ATTN message
appears on the display, report the message to your service representative.
See “FID or ATTN on the Message Display” on page 73.
Tape Winds Completely Out of the Cartridge
Call your service representative. If a FID or ATTN message appears on the
message display, record the code and report it to your service representative.
See “FID or ATTN on the Message Display” on page 73.

following steps:
1. Select Unload from the Options Menu and press Enter.
2. If an error code or a FID message appears on the message display, record
the error code or FID message and select Unload Drive and press Enter
again.

a FID or ATTN message appears on the message display, record the code
and see “FID or ATTN on the Message Display” on page 73.
