Table 7 MSL6480 events related to path failover (continued)
Details and solutionMessage and descriptionEvent code
Disable basic path failover for this drive or replace
the drive with one supporting this feature.
The drive configuration failed because of
unsupported BDPF feature selected.
4048
The drive configuration failed because of
unsupported BCPF feature selected.
4049
Check cabling and all network components between
the affected drive and host computer.
Basic data path failover occurred.4050
Check cabling and all network components between
the affected drive and host computer.
Manual control path failover from active to passive
drive failed; partition may be disconnected from
host.
4053
The partition no longer has a passive drive that is
available for control path failover. Reconfigure the
Failed to copy settings from active to passive drive

partition so that at least one drive in the partition is
available for control path failover.
Verify that the configured control path failover drive
is present, powered on, and ready to accept the
control path.
Passive control path drive not available for control
path failover.
4057
If the failover is unplanned or unexpected, verify
that the host still sees both the active and passive
Disabling active control path drive caused failover
to passive one. This event applies to Basic CPF.

drives. If necessary, reconfigure a different passive
drive for the partition.
Check cabling and all network components between
the affected drive and host computer.
Automatic control path failover by disabling LUN
drive failed; partition may be disconnected from
host.
4066
This event code is used when the user initiates the
failover from the library web interface. This is an
informational event.
Control path switched over from active to passive
drive.

Table 8 1/8 G2 Tape Autoloader and other MSL libraries events related to path failover
Details and SolutionDescriptionEvent code
The port of the FC switch connected to the library
master drive must be in NPIV mode. Verify the FC
switch configuration.
Unable to negotiate for NPIV. Library control path
failover has been disabled.
EC
Common control or data path failover issue.
Failover has been disabled.
ED
A data path failover-related error has occurred.EF
The master drive must be powered off from the
library web interface or front panel to activate
control path failover.
The master drive was removed without being
powered off. Library path failover cannot be
performed.
FF
A control path failover event occurred. The master
drive was successfully switched to the alternate
master drive. This is an informational event.
Control path failover reported.0x33
A data path failover event occurred. The active
port was successfully changed to the previous
standby port. This is an informational event.
Data path failover reported0x34
Additional tape drive sense codes
Tape drives supporting 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.
