Details and solution
4037
Loss of redundant data path.
Verify that both FC ports are correctly
cabled to the SAN.
4038
The drive configuration failed because of
unsupported ADPF features selected.
Advanced path failover, ADPF and ACPF,
are only supported on LTO-6 tape drives.
Disable advanced path failover for this drive
or replace it with a drive supporting this
feature.
4039
The drive configuration failed because of
unsupported ACPF features selected.
4040
Data path failover occurred.
Check the cabling and all network
components between the affected drive and
host computer.
4043
Control path failover occurred. This event
applies to Advanced CPF.
If the failover was 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 the cabling and all network
components between the affected drive and
host computer.
4046
The drive configuration failed because of
missing DPF license.
Disable path failover or install the necessary
failover license.
4047
The drive configuration failed because of
missing CPF license.

The drive configuration failed because of
unsupported BDPF feature selected.
Disable basic path failover for this drive or
replace the drive with one supporting this
feature.
4049
The drive configuration failed because of
unsupported BCPF feature selected.
4050
Basic data path failover occurred.
Check cabling and all network components
between the affected drive and host
computer.
4053
Manual control path failover from active to
passive drive failed; partition may be
disconnected from host.
Check cabling and all network components
between the affected drive and host
computer.
4056
Failed to copy settings from active to
passive drive in basic control path failover.
The partition no longer has a passive drive
that is available for control path failover.
Reconfigure the partition so that at least one
drive in the partition is available for control
path failover.
