Modifying RAID Group Configuration

PATCH /raidgroup/{raidgroup_id}

Introduction

Modifies the specified RAID Group settings.

Caution

  • When the assigned CMs are being changed, the system enters the Write Through mode which reduces the overall operational I/O performance of the entire device.

    Therefore, the assigned CM should be changed when business I/O is low.

  • Changing the assigned CM may take up to several tens of minutes.

  • Tenant users cannot execute this command.

Request Examples

  • Example of changing the RAID Group Name to RAIDG_2 for a RAID Group with RAID Group ID 2.
