Additional tape drive sense codes

Tape drives that support advanced path failover use vendor-specific SCSI additional sense codes (ASCs)
to report certain conditions to the failover drivers. These additional sense codes are handled by the
device driver in normal operation and should not be visible to the applications.
Description
Unable to negotiate for NPIV. Library
control path failover has been disabled.
Common control or data path failover
issue. Failover has been disabled.
A data path failover-related error has
occurred.
The master drive was removed without
being powered off. Library path failover
cannot be performed.
Control path failover reported.
Data path failover reported
Details and solution
Verify that the configured control path
failover drive is present, powered on, and
ready to accept the control path.
If the failover is unplanned or unexpected,
verify that the host still sees both the active
and passive drives. If necessary, reconfigure
a different passive drive for the partition.
Check cabling and all network components
between the affected drive and host
computer.
This event code is used when the user
initiates the failover from the library web
interface. This is an informational event.
Details and Solution
The port of the FC switch connected to the
library master drive must be in NPIV
mode. Verify the FC switch configuration.
The master drive must be powered off
from the library web interface or front
panel to activate control path failover.
A control path failover event occurred. The
master drive was successfully switched to
the alternate master drive. This is an
informational event.
A data path failover event occurred. The
active port was successfully changed to
the previous standby port. This is an
informational event.
