•
Protocol Type—Displays the protocol used to communicate with the tape library. The following
values are valid:
◦ Parallel SCSI—The protocol is Parallel SCSI.
◦ Serial ATA—The protocol is Serial ATA.
◦ SAS—The protocol is Serial Attached SCSI.
◦ Unknown—The Storage Agents are unable to determine the protocol.
•
Current Width—Displays the current negotiated data transfer width for Parallel SCSI tape
libraries. The possible values are:
◦ Narrow (8 bits)—The negotiated data transfer width for this tape library is narrow (8
data bits).
◦ Wide (16 bits)—The negotiated data transfer width for this tape library is wide (16 data
bits).
◦ Unknown—The Storage Agents are unable to determine the current negotiated data
transfer width for this tape library.
•
Current Speed—Displays the current negotiated data transfer speed for Parallel SCSI tape
libraries. The possible values are:
◦ Asynchronous—The current data transfer speed for this tape library is asynchronous.
◦ Fast—The current data transfer speed for this tape library is 10 million transfers per
second.
◦ Ultra—The current data transfer speed for this tape library is 20 million transfers per
second.
◦ Ultra2—The current data transfer speed for this tape library is 40 million transfers per
second.
◦ Ultra3—The current data transfer speed for this tape library is 80 million transfers per
second.
◦ Unknown—The agent is unable to determine the current negotiated data transfer speed
for this tape library.
NOTE: If the current data transfer width is Narrow (8 bits) then the speed in megabytes per
second is equal to the million transfers per second speed. If the current width is Wide (16
bits) then the speed in megabytes per second is twice the million transfers per second speed.
For example, if the current speed is Ultra and the width is Wide then the speed would be 40
megabytes per second.
•
Negotiated Link Rate—Displays the negotiated link rate for SAS and SATA tape libraries. The
possible values are:
◦ 1.5 Gbps—The negotiated link rate for this tape library is 1.5 gigabits per second.
◦ 3.0 Gbps—The negotiated link rate for this tape library is 3.0 gigabits per second.
◦ Unknown—The agent is unable to determine the negotiated link rate for this tape library.
◦ Door Status—Displays the status of the door. The following values are valid:
– Not Supported—The door status is not supported by the device.
– Closed—The door is closed.
– Open—The door is open.
– Unknown—The state of the tape library door cannot be determined. You may need
to upgrade the Storage Agents.
