IBM Storwize Volume Tasks

This chapter contains the following sections:

Add IBM Storwize Mirrored Copy

Summary
Add IBM Storwize Mirrored Copy
Description
This task adds a copy to an existing volume, which changes a nonmirrored volume into a mirrored volume. Creating mirrored copies of a volume allows the volume to remain accessible even when a managed disk (MDisk) that the volume depends on becomes unavailable. You can create copies of a volume either from different storage pools or by creating an image mode copy of the volume. Copies allow for availability of data; however, they are not separate objects. You can only create or change mirrored copies from the volume

Make IBM Storwize Primary Volume

Summary
Make IBM Storwize Primary Volume
Description
This task will make the secondary copy of the mirrored volume as primary. Each volume has a primary and a secondary copy, and the star indicates the primary copy. The two copies are always synchronized, which means that all writes are destaged to both copies, but all reads are always done from the primary copy. By default, the primary and secondary copies always switch between Copy 0 and Copy 1 during creation to balance the reads across your storage pools. However, always be sure that the I/Os to the primary copies are customized to the performance of all your storage pools, so therefore you can change the roles of your copies.

Migrate IBM Storwize Volume

Summary
Migrate Volume
Description
This task migrates a volume from the current storage pool to the new storage pool of same extent size. With volume migration, you can move the data between these storage pools,regardless of whether the pool is an internal pool, or a pool on another external storage system. This migration is done without the server and application knowing that it even occurred. The migration process itself is a low priority process that does not affect the performance of the IBM Storwize. However, it moves one extent after another to the new storage pool, so the performance of the volume is affected by the performance of the new storage pool after the migration process.

Split IBM Storwize Volume

Summary
Split Volume
Description
The task creates a separate volume from a synchronized copy of a mirrored volume. If this task is performend on the primary copy, the remaining secondary copy automatically becomes the primary. If your two volume copies are synchronized, you can split one of the copies to a new volume and map this new volume to another host. From a storage point of view, this procedure can be performed online, which means you could split one copy from the volume, and create a copy from the remaining one without any host impact. However, if you want to use the split copy for testing or backup purposes, you must make sure that the data inside the volume is consistent. Therefore, you must flush the data to storage to make the copies consistent.
