Perform a post-replacement inspection.
After the parts replacement, return to the SmartKit page and click Replaced. Then
complete the check after the replacement as prompted.
Check system status.
On the Parts Replacement page, click Inspection to check the system status again. If
any inspection item fails, rectify the fault based on the suggestions in the inspection
report.
After the preceding procedure is complete, check services on the host for any storage-
related error.
Replacing a BBU affects data security.
During the replacement, if all other BBUs fail, the system is no longer BBU-protected.
To enhance data security, the system forcibly implements LUN write protection, and the
system performance is compromised.
The spare part is ready.
Configuration data has been backed up.
The BBU that you want to replace has been located.
NOTE
You can locate a component in either of the following ways:
l Locating a component based on alarms in DeviceManager: On the Alarms and Events page of
DeviceManager, view the help information and locate the component to be replaced.
l Locating a component based on the status of its alarm indicator: For details about the indicators on
different components, see indicator introduction in the Product Description specific to your product.
Remove and insert a BBU with even force. Excessive force may damage the appearance
or connectors of the BBU.
Remove only one BBU at a time.
When a BBU is being replaced, the storage system does not have BBU redundancy.
Therefore, you are advised to replace a BBU as quickly as possible.
A BBU must be replaced within five minutes. Otherwise, the system heat dissipation is
compromised.
