Number of Discovery session
open failures
D/C The number of attempted discovery sessions
that failed. The failure is due to an inability
to open a connection. Some of the reasons
why a connection open might fail are:
— Initiator/host name not configured.
— Hostname could not be resolved (confirm
that iscsi_resolvd daemon is running).
— Target is unreachable (network or target
problems).
— Resource allocation failures (memory,
ISID, target ).
Number of Normal sessions
opened
I The number of normal sessions that were
opened. Normal sessions are opened to
perform I/O. In general, normal sessions are
any session other than discovery sessions.
Number of Normal session open
failures
D/C The number of attempted normal/operational
sessions that failed. The failure is due to an
inability to open a connection. Some of the
reasons why a connection open might fail are:
— Hostname could not be resolved (confirm
that iscsi_resolvd daemon is running).
— Target is unreachable (network or target
problems).
— Resource allocation failures (memory,
ISID, target).
Number of SCSI-3 REPORT
LUNs commands issued
I The number of SCSI-3 REPORT_LUNS
commands issued to iSCSI targets during
ioscans.
Number of SCSI-3 REPORT
LUNs commands issued that
failed
D The number of attempted SCSI-3 REPORT
LUNS commands that failed. The failure is
due to an incomplete I/O operation or no
support for the command by the target. Lack
of support for this command is not an error,
although it is included in this counter.
Number of SCSI INQUIRY
commands issued
I The number of SCSI INQUIRY commands
issued to iSCSI targets during ioscans.
Number of SCSI INQUIRY
commands issued that failed
D/C/T The number of attempted SCSI INQUIRY
commands that failed. The failure is due to
an incomplete I/O operation.
