scsimgr.1m (2010 09)

s
scsimgr(1M) scsimgr(1M)
Maximum number of lunpaths to
scan simultaneously per target.
This value overrides the value set
at global scope.
max_lpt_scan RW uint32
User-friendly name that can be
substituted for the HBA’s
hardware path. By default, no
value is pre-assigned (empty
string). Range: ASCII string <=
128 chars. Must begin with a
letter and may only contain
alphanumeric characters, "-", and
"_".
hwp_abs_alias RW string
User-friendly name that can be
substituted for the HBA’s com-
ponent part of its hardware path.
By default, no value is pre-
assigned (empty string). Range:
ASCII string <= 64 chars. Must
begin with a letter and may only
contain alphanumeric characters,
"-", and "_".
hwp_comp_alias RW string
Object Attribute Name RO/RW Type Description
Maximum queue depth assigned
to the target port of the target
path. Note: This attribute is only
valid when
tport_qdepth_enable
has
been set to true (1).
Range: 1 - 0xFFFFFFFE
Device Set tport_max_qdepth RW uint32
tport_
qdepth_enable
To enable/disable congestion con-
trol on the target port of the tar-
get path. Values: false (0) or true
(1).
RW boolean
To enable/disable dynamic conges-
tion control on the target port of
the target path. Values: false (0)
or true (1). Note: This attribute is
only valid when
tport_qdepth_enable has
been set to true (1).
tport_qd_dyn RW boolean
Notes:
• Setting the value of attribute
max_q_depth for a LUN, will set the queue depth for all LUN paths of
the LUN to the value specified.
• The queue depth of LUN paths of a LUN can also be changed as follows:
scsictl -m queue_depth
However scsictl -m queue_depth only affects the current value while scsimgr can set the
value persistently across system reboots.
• If
scsictl is invoked on a persistent DSF, it only affects the current value of all LUN paths. If it is
invoked on a legacy DSF, it only affects the current value of the queue depth on the LUN path
corresponding to the legacy DSF.
• If the current value is changed with the
scsictl command while the LUN is not opened, this value
will be lost when the LUN is opened. The value saved or set at a higher scope with the scsimgr com-
mand will be restored.
