Devices

Magneto-optical disks and magneto-optical disk library systems are

SCSI devices used for high-capacity read-write applications. The ability

of magneto-optical devices to randomly access vast amounts of data

makes them best suited for fast retrieval of infrequently accessed

archival data, unattended backup, and storage of large data ﬁles such as

electronic images.

Data can be written to the optical disks in raw mode or as ﬁles; cpio, dd,

and other HP-UX commands can access optical disks in raw or block

mode. LVM can be used to conﬁgure partitions on magneto-optical

devices. Note, however, that LVM is not supported for spanning disks on

magneto-optical devices.

Typically, magneto-optical disk libraries require installation by an HP

Service Engineer.

NOTE Magneto-optical devices are shipped with a shipping screw in place to

ensure that the product is not damaged in transit. Consult the hardware

documentation for instructions on removing the shipping screw before

conﬁguring the device.
