pref_tport .
Indicates whether Asymmetric Logical Unit
Access (ALUA) functionality is enabled for the
LUN instance. The value of true (1) indicates
that ALUA functionality is handled if LUN sup-
ports it. The value of false (0) indicates that
ALUA functionality is ignored even if LUN sup-
ports it.
May be:
true (1): enable ALUA
false (0): disable ALUA
alua_enabled RW boolean
retry_delay
_enabled
Enables or disables support of retry delay timer
codes returned by devices complying with
SAM-4 (SCSI Architecture Model 4), in case of
congestion. If set to false (0), retry delay timer
codes are ignored. If set to true (1), retry delay
timer codes are taken into consideration, when
handling congestion.
May be:
true (1): enable retry delay timer codes.
false (0): disable disable retry timer codes.
RW boolean
Failed LUN path connectivity test. Determines
whether the system should automatically test
the connectivity of a failed LUN path and if so
which kind of test must be performed.
May be set to:
none: No connectivity test should be per-
formed.
basic: Basic connectivity test including the
Standard Inquiry command, should be per-
formed.
extended: Extended connectivity test includ-
ing Standard Inquiry and Test Unit Ready
(TUR) commands should be performed.
ping_type RW string
Failed LUN path recovery policy. Determines
when a failed LUN path should be considered
back online when automatic connectivity test is
enabled.
May be set to:
immediate: Upon a successful connectivity
test.
count_based: After a number of consecutive
successful connectivity tests specified by the
attribute ping_count_threshold.
time_based: Upon sustained successful con-
nectivity tests within the time period specified
in the attribute ping_time_threshold.
ping_recovery RW string
ping_time _thres-
hold
Minimum time in seconds, of sustained success-
ful connectivity tests before a failed LUN path
is considered back online.
Range: 0 - 0xFFFFFFFF
RW uint32
ping_count _thres-
hold
Minimum number of consecutive successful
connectivity tests before a failed LUN path is
considered back online.
Range: 0 - 0xFFFFFFFF
RW uint32
Seconds to wait after a LUN transitioned out of
ONLINE state before failing I/Os.
Range: 0 - 0xFFFFFFFE
Device Set transient_secs RW uint32
