Tentatively Enabling the Rule
A tentatively-enabled rule is configured to appear in the system logs (syslog) as
“tentative,” showing the potential effects of the rule if it was enabled. (The log
component, POLICY_ACTION, creates the syslog messages; syslog access and log
components are described in the CLI Maintenance Guide.) If you configured
reporting for the rule (as shown above), the report shows which files would be
migrated if the rule was fully enabled. Tentative rules do not change policy
enforcement, but they do consume processing time in the policy software. From
gbl-ns-vol-plc mode, use the
enable tentative command to tentatively enable the
placement rule:
enable tentative
Use
show logs syslog or grep pattern logs syslog to view the syslog.
For example, the following command sequence puts the “emptyRH” rule into a
tentative state:
bstnA6k(gbl)# namespace wwmed
bstnA6k(gbl-ns[wwmed])# volume /acct
bstnA6k(gbl-ns-vol[wwmed~/acct])# place-rule emptyRH
bstnA6k(gbl-ns-vol-plc[wwmed~/acct~emptyRH])# enable tentative
bstnA6k(gbl-ns-vol-plc[wwmed~/acct~emptyRH])# ...
Disabling the Rule
Disabling the rule removes it from consideration. Use no enable from gbl-ns-vol-plc
mode to disable a placement rule:
no enable
For example, the following command sequence disables the “emptyRH” rule:
bstnA6k(gbl)# namespace wwmed
bstnA6k(gbl-ns[wwmed])# volume /acct
bstnA6k(gbl-ns-vol[wwmed~/acct])# place-rule emptyRH
bstnA6k(gbl-ns-vol-plc[wwmed~/acct~emptyRH])# no enable
bstnA6k(gbl-ns-vol-plc[wwmed~/acct~emptyRH])# ...
