This project includes scripts and policies for IBM Spectrum Scale ILM in combination with IBM Spectrum Archive Enterprise Edition and IBM Spectrum Protect for Space Management. For more inforemation refer to the IBM Spectrum Scale ILM policy whitepaper.
Folder immutable - Script to set files to immutable
This folder contains a script and policies to identify files that are not immutable in an immutable fileset and sets these identified files to immutable. The makeimmutable.sh script is an external pool script that receives the input from an EXTERNAL LIST policy and sets all files identified by the LIST policy to immutable using the mmchattr -i yes command. The retention period is defined in the policy itself and is applied to each file by setting the retention time to current date and time plus retention period
Folder list - List policy script
This folder contains a wrapper script for LIST policies. The main purpose is to list the numbers and optionally the file names of file in accordance to their migration state. This wrapper script can be dynamically extended to use other list policies.
Folder premigrate - Premigrate policies and scripts
This folder contains script and policies to perform premigrates using migrate policies. It provides an interface script that wraps perform pre-migration instead of migration. It contains an interface script for Spectrum Archive.
Folder quota-migration - migration when quota limits have reached
This folder contains a callback script and policies facilitating migration of files for filesets where the soft quota limit has been reached. The callback script (callback-quota.sh) is invoked when the event softQuotaExceeded is triggered for a fileset. This script invokes an EXTERNAL LIST policy to identify files in the fileset that qualify for migration based on the quota limits and a migration policy that migrates the files identified by the list policy to IBM Spectrum Archive EE.
Folder Recall - wrapper script for tape optimized recalls
This folder contains script and policies for tape optimized recalls with Spectrum Protect for Space Management and Spectrum Archive Enterprise Edition . The scripts are customized interface scripts that perform recall instead of migration.
Folder receiver - external script invoked by EXTERNAL LIST policy
This folder includes an interface script that receives file lists from an EXTERNAL LIST policies and processes the files contained in the file list. The processing in this script extracts the file names contained in the file list and writes these file names to an extra file. Of course you can add other operations for the files.
Folder runpolicy - wrapper for mmapplypolicy
This folder contains a wrapper script for the mmapplypolicy command. It is invoked in a simplified way and allows either pass further options for the mmapplypolicy commmand or encode these options in an internal variable.
Folder sample-policies - sample ILM policies
This folder includes sample policies for migration, recall and list.
