Choosing the Target Storage
The next step in configuring a placement rule is to choose the target storage for the
share’s files. You can choose one target: another share or share farm in the current
volume. From gbl-ns-vol-plc mode, use one of two
target rules to set the share’s
storage target:
target share share-name
where share-name (1-64 characters) is a share from the current volume.
target share-farm share-farm-name
where share-farm-name (1-64 characters) is a share farm within the current
volume.
For example, the following command sequence selects a share farm, “fm1,” as the
target for the “emptyRH” placement 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])# target share-farm fm1
bstnA6k(gbl-ns-vol-plc[wwmed~/acct~emptyRH])# ...
As another example, the following command sequence selects a share, “nas3,” as the
new home for all files in the source share:
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])# target share nas3
bstnA6k(gbl-ns-vol-plc[archives~/etc~move2nas])# ...
Balancing Capacity in a Target Share Farm
When a share farm is a file-placement target, the first configured share in the farm is
the default share for placed files. Most files are placed on the same share as their
parent directory, but a file defaults to the first share if its parent directory is outside
the share farm. The first share in the farm can therefore take a heavier file burden over
time.
