Number of target authentication
timeouts
I/C The number target authentication timeouts
that occurred during communication with the
userspace iradd daemon.
Number of target authentication
failures
I/C The number of target authentication failures
for CHAP. Either the target’s CHAP
information is not configured in the RADIUS
server, or the CHAP information provided by
the target is incorrect.
Number of temporary
redirection requests
I Number of temporary login redirections
requested by a target device.
Number of permanent
redirection requests
I Number of permanent login redirections
requested by a target device.
Number of kernel memory
allocation failures
D The number of memory allocation attempts
for a kernel PDU structure that failed. A
failure to allocate a PDU structure means
that some outbound command, or a NOP-OUT
in response to a NOP-IN, could not be
completed. As a result:
— The regular occurrence of this event will
have a negative impact on performance.
— Failed I/Os will be retried according to
existing SCSI retry policies (same as
Fibre Channel and parallel SCSI),
however, there is no retry policy for native
iSCSI commands.
Number of streams message
allocation failures
D The number of streams message memory
allocation attempts that failed. The regular
occurrence of this event will have a negative
impact on performance. Failed I/Os will be
retried according to existing SCSI retry
policies (same as Fibre Channel and parallel
SCSI).
Number of PDU transmission
failures due to an offline
connection
D The number of transmission attempts of
native iSCSI commands that failed, because
the connection on which the I/O was
attempted, was offline. The regular
occurrence of this event will have a negative
impact on performance. Failed I/Os will be
retried according to existing SCSI retry
policies (same as Fibre Channel and parallel
SCSI).
