Administering storage policies for object storage

Use the following information to create, list, and change storage policies for object storage.

Important:

CES Swift Object protocol feature is not supported from IBM Storage Scale 5.2.0 onwards.
IBM Storage Scale 5.1.8 is the last release that has CES Swift Object protocol.
IBM Storage Scale 5.2.0 will tolerate the update of a CES node from IBM Storage Scale 5.1.8.
- Tolerate means:
  - The CES node will be updated to 5.2.0.
  - Swift Object support will not be updated as part of the 5.2.0 update.
  - You may continue to use the version of Swift Object protocol that was provided in IBM Storage Scale 5.1.8 on the CES 5.2.0 node.
  - IBM will provide usage and known defect support for the version of Swift Object that was provided in IBM Storage Scale 5.1.8 until you migrate to a supported object solution that IBM Storage Scale provides.
Please contact IBM for further details and migration planning.

Before you create a storage policy with the file-access (unified file and object access) function that is enabled, the file-access object capability must be enabled. For more information, see Object capabilities and Managing object capabilities.

To create a new storage policy with the unified file and object access feature that is enabled, run the following command:

mmobj policy create sof-policy --enable-file-access

A sample output is as follows:

[I] Getting latest configuration from ccr
[I] Creating fileset /dev/gpfs0:obj_sof-policy
[I] Creating new unique index and build the object rings
[I] Updating the configuration
[I] Uploading the changed configuration

To list storage policies for object storage with details of functions available with those storage policies, run the following command:

mmobj policy list --verbose

A sample output is as follows:


Index       Name          Deprecated Fileset  Fileset Path                       Functions               Function Details  File System
----------------------------------------------------------------------------------------------------------------------------------------
0           SwiftDefault  object_fileset      /ibm/cesSharedRoot/object_fileset                                            cesSharedRoot
11751509160 sof-policy    obj_sof-policy      /ibm/cesSharedRoot/obj_sof-policy  file-and-object-access  regions="1"       cesSharedRoot
11751509230 mysofpolicy   obj_mysofpolicy     /ibm/cesSharedRoot/obj_mysofpolicy file-and-object-access  regions="1"       cesSharedRoot

To change a storage policy for object storage, run the following command:
```
mmobj policy change
```
To change the default storage policy, run the following command:
```
mmobj policy change sof-policy --default
```
The system displays sof-policy as the default storage policy.
