LTO-Cartridge Memory (LTO-CM) Issues
The LTO-CM stores information that is normally stored in the header at
the beginning of the tape, including identification and usage information
such as the number of times the cartridge has been loaded, when it was
last cleaned, and error logs. If the LTO-CM becomes damaged, you may
experience difficulty with the cartridge.
Table D-12 LTO-CM Issues
Problem Cause Solution
A new data
cartridge that is
write-enabled is
rejected by the
drive. LTO-CM has failed
or is damaged. Replace data cartridge.
A new data
cartridge that is
write-protected is
rejected in multiple
known good drives. LTO-CM has failed
and the drive has
found no data to
recover. Replace data cartridge.
A cartridge that has
data written to it
and is write-
enabled is rejected
by the drive. LTO-CM has failed
or is damaged. The data can still be
recovered. Contact
your support
representative for
more information.
After data recovery,
replace the cartridge.
A cartridge that has
data written to it
and is write-
protected restores
very slowly. LTO-CM has failed
and the drive cannot
use the tape
directory information
to recover the data. The data can still be
recovered, but may
take longer than
normal.
