Description: External Tape Drive Current Width.
The following values are defined:
other(1) The agent is unable to determine the current negotiated data transfer width for this drive.
narrow(2) The negotiated data transfer width for this drive is narrow (8 data bits).
wide16(3) The negotiated data transfer width for this drive is wide (16 data bits).
What is cpqFcTapeDriveCurrentWidth?
This enumerated value reports the currently negotiated SCSI data transfer width for the tape drive, as other, narrow (8 data bits), or wide16 (16 data bits). An admin checks this to confirm the drive is running at its full rated bus width, since a drive that negotiated down to narrow could suffer reduced backup throughput. For example, narrow(2) on a drive rated for wide operation would suggest a cabling or bus negotiation problem worth investigating before the next large backup job.
