Description: Drive Array Tape Library Current Width.
The following values are defined:
other(1) The agent is unable to determine the current negotiated data transfer width for this library.
narrow(2) The negotiated data transfer width for this library is narrow (8 data bits).
wide16(3) The negotiated data transfer width for this library is wide (16 data bits).
What is cpqDaTapeLibraryCurrentWidth?
cpqDaTapeLibraryCurrentWidth reports the negotiated SCSI data transfer width for a tape library: other, narrow (8 bits), or wide16 (16 bits). A library unexpectedly negotiating narrow can indicate a cabling or termination problem limiting the throughput of every tape drive routed through it. For example, if backup jobs across an entire library run slower than expected and it reports narrow instead of wide16, an admin would check the library's own SCSI cabling before inspecting individual drives.
