N/AThis message can occur in a
heterogeneous HBA environment
Device instance DSM_name of
pseudo-LUN was rejected because
40
if one HBA’s maximum transferthe maximum transfer length of the
length is smaller than any otherunderlying adapter is too low. The
HBA’s maximum transfer length.device will be accepted after a
reboot. This message indicates that a
device instance, exposed through
the HBA whose maximum transfer
length is too small, was
considered un-useable, but will
be made useable after a reboot.
N/AThis message can occur in a
heterogeneous HBA environment
One or more of your multipath
adapters have mismatched

length is smaller than any otherexperience suboptimal performance
with device pseudo-LUN. HBA’s maximum transfer length.
This message simply indicates a
maximum transfer length
mismatch; all device instances for
this particular device are
considered useable. However,
this may cause suboptimal
performance.
N/AThis message can occur in a
heterogeneous HBA environment
Device instance DSM_name of
pseudo-LUN was rejected because
42
if one HBA’s miniport supportsit 42 does not support extended
SRBs using theSRBs. The device will be accepted
after a reboot. STORAGE_REQUEST_BLOCK
structure, but at least one other
HBA only supports the
SCSI_REQUEST_BLOCK structure.
A reboot will ensure that device
instances exposed through the
latter HBA are made useable.
N/AThis message can occur in a
heterogeneous HBA environment
Device instance DSM_name of
pseudo-LUN was rejected because
43
if all the HBA’s miniports supportits supported address type does not
SRBs usingmatch. The device will be accepted
after a reboot. STORAGE_REQUEST_BLOCKs,
but the HBAs support different
address types.
N/AThis message can occur in a
heterogeneous HBA environment
One or more of your multipath
adapters do not support extended
44
if one HBA’s miniport supportsSRBs. You may experience
SRBs using thesuboptimal performance with device
pseudo-LUN. STORAGE_REQUEST_BLOCK
structure, but at least one other
HBA only supports the
SCSI_REQUEST_BLOCK structure.
In this case, all HBAs are forced
to use SCSI_REQUEST_BLOCK so
that all device instances can be
used. However, this may cause
suboptimal performance.
