See “Rule definitions and attributes” on page 456.
Discovering what a rule does
To obtain details about what a rule does, use the info keyword, as in the
following example:
# vxse_stripes2 info
VxVM vxse:vxse_stripes2 INFO V-5-1-6153 This rule checks for
stripe volumes which have too many or too few columns
Displaying rule attributes and their default values
To see the attributes that are available for a given rule, use the list keyword. In
the following example, the single attribute, mirror_threshold, is shown for
the rule
vxse_drl1:
# vxse_drl1 list
VxVM vxse:vxse_drl1 INFO V-5-1-6004
vxse_drl1 - TUNEABLES default values
----------------------------------------------------------
mirror_threshold - large mirror threshold size
Warn if a mirror is of greater
than this size and does not have
an attached DRL log.
To see the default values of a specified rule’s attributes, use the check keyword
as shown here:
# vxse_stripes2 check
vxse_stripes2 - TUNEABLES
----------------------------------------------------------
VxVM vxse:vxse_stripes2 INFO V-5-1-5546
too_wide_stripe - (16) columns in a striped volume
too_narrow_stripe - (3) columns in a striped volume
Storage Expert lists the default value of each of the rule’s attributes.
See “Rule definitions and attributes” on page 456.
To alter the behavior of rules, you can change the value of their attributes.
See “Setting rule attributes” on page 448.
Running a rule
The run keyword invokes a default or reconfigured rule on a disk group or file
name, for example:
info Describes what the rule does.
list Lists the attributes of the rule that you can set.
run Runs the rule.
