2 If the tape drive is attached to an LVD SCSI controller, verify that it
does not share the SCSI bus with another active SCSI device by:
•Checking:
• Windows Device Manager
• Unix/Linux logs
• Monitoring the SCSI controller activity during system startup.
3 The method of performing tape backups can be a factor in slow
backup operations. Data sent to the tape drive over a network
connection and delays in data transfer over a network connection can
cause backups to slow down.
To determine whether the method of performing tape backups is a
factor:
a Use the tape diagnostic software to perform a write/read test.
The diagnostic write/read test evaluates the connection between
the tape drive and the SCSI controller and removes the network
data transfer and the backup software from the performance
evaluation.
IF the tape drive . . . THEN . . .
shares the SCSI bus with
other SCSI devices that are
active when tape backups are
performed,
reconfigure the SCSI setup to
make the tape drive the only
active device on the SCSI bus.
is the only active device on
the SCSI bus
proceed to step 3 of this
procedure to determine
whether the method of
performing tape backups is a
factor.
Caution: The read/write test will overwrite any data on the
tape. Always use a new/blank or “scratch”
cartridge for diagnostic read/write tests.
