To add additional disk storage to your Charon-SSP instance (for example, for storing virtual disk containers), perform the steps described below.

Steps in the IBM Storage Environment

In the IBM environment, you can, for example,

create a new storage volume,
attach an existing storage volume to your instance,
detach a storage volume from your instance.

These steps are shown below.

For more details, please refer to the IBM documentation

Creating a New Volume

To create a new volume, start with the following steps:

Open the Block storage volume page in the Storage section of the VPC environment. This opens a list of available disks.
To create a new disk, click on the Create button.

The image below illustrates these steps:

The Create button opens a block storage volume creation window. Add the necessary parameters, for example:

Name of the volume
Resource group of the volume
Disk performance
Disk size
Encryption configuration

The following image shows the upper part of the volume creation window:

When all the necessary data has been entered, create the volume by clicking on Create volume on the right.

Attaching an Existing Volume to an Instance

To attach a volume to an instance, perform the following steps:

Open the list of Block storage volumes.
Click on the disk you want to assign to an instance. This opens the disk details view.
In the details view, click on Attach instance as illustrated below.
In the pop-up window select your instance and click on Attach volume:
The instance will be listed in the Attached instances section.

Detaching a Volume from an Instance

Before detaching a volume from an instance, make sure that the volume is not needed and your applications will not run into problems if the volume is detached. Then, perform the following steps:

Unmount the volume if it is mounted, and remove it from /etc/fstab if needed.
Open the list of Block storage volumes.
Click on the disk in question to open the details view.
Click on the round delete symbol next to the instance in the Attached instances section.

Steps on the Charon-SSP Host System

Mounting a Newly Attached Volume

Unmounting a Volume

To unmount a volume before perform the following steps:

Stop all Charon instances that might use the volume that is about to be unmounted.
Use the command
# umount <device-path> or # umount <mount-point>
To make this permanent, remove the corresponding entry in /etc/fstab.
