Complete the Expansion Process

After cabling the new Drive Enclosures in the Oracle FS System, complete the expansion process.

For more information involving the following steps, refer to Oracle Flash Storage System CLI Reference and Oracle Flash Storage System Administrator’s Guide.

If you brought the system offline during the add procedure, restart the system.
1. If you are using Oracle FS System Manager (GUI), select Oracle FS > Restart.
2. If you are using Oracle FS CLI (FSCLI), issue fscli system ‑restart.
If the system remained in production during the add procedure, re-enable Call-Home events.
1. If you are using the GUI, navigate to System > Networking.
2. Select Actions > Modify > Notifications.
3. Select the Enable event triggered Call-Home check box and click OK.
4. If you are using the FSCLI, issue fscli call_home ‑modify ‑enableEventTrigger.
Accept the new drives into the system.
If you are using the GUI, complete the following steps:
1. Navigate to System > Alerts and Events > System Alerts.
2. Double-click the Foreign Disk Drive system alert.
3. Click Accept New Drives.
4. Click OK.
  The system updates the statuses of each new drive and automatically creates drive groups.
If you are using the FSCLI, complete the following steps:
1. Issue fscli system_alert –list –details to view the system alert for foreign drives.
  The alert displays the Drive Enclosure identifier and the foreign drives.
2. Issue fscli enclosure ‑modify ‑enclosure enclosure‑id‑or‑fqn ‑acceptDrive drive‑slot‑number [, drive‑slot‑number]....
  The system updates the statuses of each new drive and automatically creates drive groups.
Use the GUI to verify that the system discovers the newly added Drive Enclosures.
1. Navigate to System > Hardware > Drive Enclosures.
2. From the Drive Enclosures Overview page, monitor the status of the new Drive Enclosures as the system discovers them.
  Verify that each Drive Enclosure has a status of Normal and the drive groups have a status of Unassigned.
As necessary, arrange the drive groups into the Storage Domains where extra storage is needed.
For more information about managing drive groups and Storage Domains, refer to Oracle Flash Storage System Administrator’s Guide and Oracle Flash Storage System CLI Reference.

When a volume is created, it is possible that the Oracle FS System provisions the volume across fewer drive groups than the optimal number that would satisfy the desired QoS settings for the volume. This situation can occur when an insufficient number of drive groups are available in the Storage Domain in which the volume is created.

However, when Drive Enclosures are added to that Storage Domain and Enable Automatic QoS Rebalancing is enabled, the Oracle FS System attempts to correct the sub-optimal provisioning. The correction is accomplished by scanning for all volumes that are sub-optimally provisioned in that Storage Domain.

If certain conditions exist, the system begins migrating the data for those volumes to the newly available drive groups that are provided by the new Drive Enclosures. The scanning and the migration depend on the Storage Class of each volume in the Storage Domain. The migration occurs only when sufficient free space exists in the same Storage Class that is configured for the volume.

The QoS rebalance occurs during a daily scan; therefore, QoS rebalance might not happen for up to 24 hours. However, as drive groups are added, you can select Rebalance Volume Data in the GUI or FSCLI to take advantage of the new storage without waiting for the daily scan. The Rebalance Volume Data function only rebalances the volumes that are in the same Storage Classes as the new drive groups and only if suboptimal volumes exist in the provisioning.
