• Bootcode Firmware Revision.
• Library Mode.
• Automatic — the device will switch from Sequential to Random mode if it receives media
changer SCSI commands.
• Manual — the device will stay in the current mode until another mode is configured by a user.
• Random — the device will not automatically load and unload tapes. Instead, it will wait for
commands from the backup software or the OCP to load and unload tapes.
• Sequential — the device will automatically unload the tape in the drive when the host software
sends an unload command to the drive and then automatically load the tape from the next
highest sequentially numbered full slot.
• Loop — in Loop mode, the Library will load the tape from the lowest numbered full slot after
the tape from the highest numbered full slot is unloaded. If Loop is not listed, the Library will
stop automatically loading and unloading tapes after the tape from the last full slot is unloaded.
CAUTION:
Since loop mode will endlessly cycle through the tapes, it is possible to overwrite old data.
Make sure that there are enough tapes in the Library or that the tapes are regularly rotated
in and out to ensure that data you want to save is not overwritten.
• Autoload — the device will automatically load the tape from the lowest numbered full slot on
power up.
• WWide Node Name — a world wide unique identifier that the Library reports over SCSI and
may be used by operating systems or software applications to identify and track the Library.
The Library Extender pane displays information about the Library Extender.
• Firmware revision — the version of Library Extender firmware.
• Serial Number — the electronic serial number for the Library Extender.
The Lower Library Information pane displays information about the lower Library.
• Serial Number — the electronic serial number for the lower Library. This serial number should
match the serial number printed on the Library label, located on the pull out tab under the drive
or lowest drive bay cover on the back of the Library.
• Product ID — how the device identifies itself to the host computer. This will always be MSL G3
Series.
• Currently Installed Library Firmware x.xx / y.yy
• x.xx is the version of the Library controller firmware. This number is used to reference firmware
versions when downloading new firmware from the HP website.
• y.yy is the version of the robotics firmware.
• Library Height
• 2U is an MSL2024
• 4U is an MSL4048
Viewing Library status
To view a summary of the extended library status, use the RMI System Status pane.
