Policy for Balancing Capacity
Draining One or More Shares
12-38 CLI Storage-Management Guide
To migrate files off of any share that is running low on free space, you can configure
auto migration for the share farm. Refer back to “Auto Migrating Existing Files” on
page 12-18 to configure auto migration.
Applying a Schedule (optional)
You can optionally run the placement rule at a later start time, set by a schedule. By
default, placement rule runs as soon as you enable it, empties the share(s) of all files,
and then keeps the share empty. If you limit the amount of data that can migrate in
each run (as described later), the schedule can stagger the migration over multiple,
smaller runs.
Use the gbl
schedule command to create a schedule; refer back to “Creating a
Schedule” on page 12-27 for details. To apply a schedule to the placement rule, use
the
schedule command in gbl-ns-vol-plc mode:
schedule name
where name (1-64 characters) identifies the schedule. Use the
show policy
command to list all schedules.
For example, the following command sequence applies a schedule to the “move2nas”
rule:
bstnA6k(gbl)# namespace archives
bstnA6k(gbl-ns[archives])# volume /etc
bstnA6k(gbl-ns-vol[archives~/etc])# place-rule move2nas
bstnA6k(gbl-ns-vol-plc[archives~/etc~move2nas])# schedule fri5pm
bstnA6k(gbl-ns-vol-plc[archives~/etc~move2nas])# ...
Removing the Schedule
Use no schedule to make the placement rule run when enabled:
no schedule
For example:
bstnA6k(gbl)# namespace wwmed
bstnA6k(gbl-ns[wwmed])# volume /acct
bstnA6k(gbl-ns-vol[wwmed~/acct])# place-rule emptyRH
