StorageTek Protected
Drives
You may mix drive types within a library, but please observe the following cautions and
tables:
CAUTION:
Possible data corruption: StorageTek does not advise you to mix DLT
7000 and DLT 8000 drives in the same library. If a DLT 7000 cartridge is
inserted into a DLT 8000 drive, the tape can be read and written on in
7000 mode. If a DLT 8000 cartridge is inserted into a DLT 7000 drive and
a read command is issued, the drive will indicate Medium Error/
Calibration Error (03/8000). If a write command is issued at load point, as
with most drives, the drive will write over any data present.
CAUTION:
Data loss: StorageTek does not advise mounting SDLT 320-formatted
cartridges into SDLT 220 drives. An SDLT 220 drive will overwrite the 320
data. To avoid this, carefully manage the locations of the cartridges
within your library, and designate the correct drive type for your read/
write operations.
Do not mix LVD and HVD operations on the same bus.
DLT1 drives use only DLTtape IV cartridges, and can read—but not write to—
DLTtape IV cartridges formatted by DLT 4000 drives.
DLT1 drives use their own cleaning cartridge, part 100099401. Do not use this
cartridge in DLT drives.
