6.1 HP IBRIX X9000 Network Storage System CLI Reference (TA768-96057, June 2012)

ibrix_tier
Manages data tiers.
Description
A tier is a group of one or more segments. Tiering enables automatic migration of files from one
tier to another within the same file system. User-written rules based on file attributes (such as
modification time, access time, file size, or file type) define the migration policy, determining which
files are to be moved and when. Tiers are defined on segments, not individual files.
Use of the tiering structure on any file system is optional. Tiering is off by default, and there is no
“default tier.”
The ibrix_tier command assigns or unassigns segments to tiers, deletes segments from tiers,
and lists information about tiers.
Use ibrix_migrator to create or delete rules defining migration policies, to start or stop tier
operations, and to list information about rules and migrator operations.
