Writing tiering rules
A tiering policy consists of one or more rules, each identifying a desired movement of files between
tiers. Rules are written using the GUI or directly to the configuration database with the
ibrix_migrator -A command.
This section provides definitions of rule components and examples of rules.
Operators and date/time qualifiers
The valid rules operators are: <, <=, =, !=, >, >=, plus boolean and and or.
Use the following qualifiers for fixed times and dates:
• Time: Enter as three pairs of colon-separated integers specifying time on a 24-hour clock. The
format is hh:mm:ss (for example, 15:30:00).
• Date: Enter as yyyy-mm-dd [hh:mm:ss], where time of day is optional (for example,
2008-06-04 or 2008-06-04 15:30:00). Note the space separating the date and time.
When specifying an absolute date, an absolute time, or both, the rule must use a compare type
operator (< | <= | = | != | > | >=). For example:
ibrix_migrator -A -f ifs2 -r "atime > '2010-09-23' " -S TIER1 -D TIER2
Use the following qualifiers for relative times and dates:
• Relative time: Enter in rules as year or years, month or months,week or weeks, day or
days, hour or hours.
• Relative date: Use older than or younger than. The rules engine uses the time the
ibrix_migrator command starts execution as the start time for the rule. It then computes
the required time for the rule based on this start time. For example, ctime older than 4
weeks refers to that time period more that 4 weeks before the start time.
