Swappable Components; Getting Recommended Actions - HP 3PAR StoreServ 7450 Service Manual

Swappable Components

Colored touch points on a storage system component (such as a lever or latch) identify whether
the system should be powered on or off during a part replacement:
Hot-swappable – Parts are identified by red-colored touch points. The system can remain
powered on and active during replacement.
CAUTION:
However, they should only be removed on the advice of a qualified 3PAR administrator or
HP service technician after the fault LED is turned on, and after all the data has been vacated
and reconstructed to other drives.
Warm-swappable– Parts are identified by gray touch points. The system does not fail if the
part is removed, but data loss may occur if the replacement procedure is not followed correctly.
Cold-swappable – Parts are identified by blue touch points. The system must be powered off
or otherwise suspended before replacing the part.
CAUTION:
Do not replace cold-swappable components while power is applied to the product. Power off
the device and then disconnect all AC power cords.
Power off the equipment and disconnect power to all AC power cords before removing any
access covers for cold-swappable areas.
When replacing hot-swappable components, allow approximately 30 seconds between
removing the failed component and installing the replacement. This time is needed to ensure
that configuration data about the removed component is cleared from the system registry. To
prevent overheating due to an empty enclosure or bay, use a blank or leave the slightly
disengaged component in the enclosure until the replacement can be made.
Nodes must be replaced within 30 minutes and all other parts within 6 minutes.
Before replacing a hot-swappable component, ensure that steps have been taken to prevent
loss of data.

Getting Recommended Actions

This section explains the steps required to get from an alert message to the action associated with
the alert.
The Component line in the right column lists the cage number, magazine number, and drive number
(cage:magazine:disk). The first and second numbers are sufficient to identify the exact disk in a
StoreServ system, since there is always only a single disk (disk 0) in a single magazine. The
information displayed in the Component line depends on the type of components causing the alert.
28 Servicing the Storage System
Disk drives are warm swappable even though they have yellow touch points.
