Question 29 - D-PSC-MN-01 discussion

In Dell PowerScale Gen6 hardware, terracotta-colored handles indicate that a component is not hot-swappable. This means the component must not be removed or replaced while the node is powered on and operational. Removing such components while the system is online could lead to data loss or hardware damage.

Color-Coded Handles in Gen6 Hardware:

Blue Handles:

Indicate components that are hot-swappable.

Can be safely removed or replaced while the node is online.

Terracotta (Orange) Handles:

Signify components that are not hot-swappable.

Require the node to be powered down before removal or replacement.

Components with Terracotta Handles:

Examples Include:

Power supplies (in some configurations).

Certain internal components like fans or system boards.

Safety Precautions:

To prevent electrical hazards or system instability, these components should only be serviced when the node is shut down.

Maintenance Procedures:

Shutting Down the Node:

Use the isi_for_array -s 'shutdown -p now' command to safely power down the node.

Ensure that the node is properly removed from the cluster to prevent data access issues.

Physical Removal:

Once powered down, the component with the terracotta handle can be safely removed.
