To flash an LED on a hard drive and bring a disk back online using the DD System Manager or DDOS CLI, follow these general steps:
Step 1: Identify the Disk
In DD System Manager:
Go to the Hardware section in the sidebar.
Locate the list of disks, and find Disk 1.5 (the offline disk).
In DDOS CLI (if using CLI):
Use the command to list disks and confirm the status of Disk 1.5.
Command example: disk show state or disk show summary.
Step 2: Flash the LED on the Disk
In DD System Manager:
In the Hardware section, select Disk 1.5.
Look for an option like Flash LED or Locate Drive to help identify the physical disk.
Activate the LED flash to identify the disk physically.
In DDOS CLI:
Use the command: disk locate 1.5 to flash the LED for Disk 1.5.
Step 3: Bring the Disk Back Online
In DD System Manager:
After identifying the disk, check for options to Bring Online or Reactivate Disk 1.5.
Select the option to return the disk to operation.
In DDOS CLI:
Use the command: disk unfail 1.5 to bring the disk back online.
Step 4: Verify the Disk Status
Confirm in DD System Manager or by using the disk show state command in CLI that Disk 1.5 is now online and functioning.
After completing these steps, the LED should flash to help locate the disk physically, and then Disk 1.5 will be returned to an operational state. Let me know if you need further guidance!

Cloud tier migration from DDVE instances to physical PowerProtect DD systems like DD6900 is not supported, meaning data in the cloud tier cannot be directly transferred, necessitating alternative migration methods or data retrieval strategies.

The FS25 enclosure is compatible with DD9900, DD6900, and DD9400, providing additional storage capacity and performance capabilities tailored for high-demand PowerProtect DD deployments.

When implementing Link Aggregation Control Protocol (LACP) on a PowerProtect DD appliance, a virtual network interface is created to aggregate the physical interfaces into a single logical link. This configuration is essential to enable LACP functionality, as it allows the system to balance network traffic effectively across multiple physical connections, enhancing redundancy and throughput. By aggregating these physical interfaces, the appliance can better handle high data volumes, providing stable and efficient access to the underlying network resources.
The virtual network interface manages the logical grouping, ensuring seamless failover and load balancing between the physical links that comprise the aggregated connection.
