Attach and Claim Storage on SRN

Updated by Sharon Wang on May 08, 2017

Article Overview

This article explains how to

  1. Attach storage on a single SRN in CenturyLink Cloud and VMware
  2. Claim storage on a single SRN from the SafeHaven Console

After the SRN has been registered with the SafeHaven Console, the next step is to attach storage to it before creating Protection Groups. Once the storage is attached, the user has to claim the attached storage and allocate it to a Storage Pool in order to use the storage for Protection Group creation. Storage Pool lets the user allocate the attached storage for creating a single or multiple Protection Groups. A single Storage Pool can span across multiple disks.

NOTE: For ease of management and troubleshooting it is recommended that the user creates one Storage Pool per Protection Group.

NOTE: Once a disk has been claimed and allocated to a Storage Pool and there is a requirement to expand that Storage Pool, then the user should NOT expand that the existing claimed disk on the SRN but instead attach a new disk and claim it to the same Storage Pool.

Requirements

  1. Access to the SRN in CenturyLink Cloud portal
  2. Access to the SRN in VMware environment
  3. Access to the SafeHaven Cluster

Assumptions

This article assumes that the user has already registered the SRN within the SafeHaven Console and wants to add storage to the SRN before creating Protection Groups.

Add storage to SRN in CenturyLink Cloud

Select Servers under the Infrastructure tab. In the Navigation Tree, select the SRN, you want to add storage to, then scroll down on the main data panel and select edit storage.

Upgrade

Select add storage and then in the drop-down menu select raw disk.

NOTE: DO NOT select a partitoned disk.

Upgrade

Add required storage and apply. Wait for the job to complete.

Upgrade

NOTE: DO NOT expand an existing disk on the SRN after it has been claimed.

Add storage to SRN in VMware Data Center

Right click on the SRN in the VMware data center, select Edit Settings.

Upgrade

On the pop-up panel, click on Add to add new devices.

Upgrade

Select Hard Disk then click Next.

Upgrade

Select Create a new virtual disk and click Next.

Upgrade

Enter the Disk Size and select Thin Provision (depending on your environment you can also select Thick Provision Lazy Zeroed). Specify a datastore location and click Next.

Upgrade

Leave the default option SCSI(0:1) as the Virtual Device Node (as this is the first disk being added) and click Next.

Upgrade

Confirm all the information is correct, click on Finish to add the new disk.

Upgrade

NOTE: Following this procedure the user can add multiple disks to the SRN.

NOTE: DO NOT expand an existing disk on the SRN after it has been claimed.

Claim storage pools for each SRN

Once the storage has been attached to the SRN, the next step is to login to the SafeHaven Console, go to the Navigation Tree and select the SRN. In the Properties Panel select Claim Storage Pool.

Upgrade

If this is the first storage device you are claiming, then select the Storage Device you want to claim and click on the Create a New Storage Pool. Provide the new pool a Name and click Claim.

Upgrade

Depending on the protection group architecture, the user can claim another disk following a similar procedure and can either Create a new Storage Pool or Add to an existing Storage Pool

Perform a similar task for all the registered SRN's.
