Best Practice
Plan carefully for any drive shelf hot-add activity on production storage systems. Verify that the
following conditions are met:
• The existing power infrastructure can support the additional hardware.
• The cabling plan for the new shelf does not simultaneously interrupt both SAS expansion paths for
controller A and controller B to the expansion-drive shelves.
• The new expansion port 1 path is confirmed to be valid, and the new shelf is visible in the
SANtricity management software before the expansion path 2 is disconnected and moved to the
new shelf.
Note: Failure to preserve one active path to existing drive shelves during the procedure could
potentially result in degradation/failure of LUNs during I/O activity.
7 E-Series Product Support
NetApp E-Series storage systems are identified by the serial number (SN) of the E-Series system shelf,
not the SNs of the individual controllers in the E-Series system shelf. The correct SN must be registered
for an E-Series system because only the SN of the E-Series system shelf can be used to log a support
case with NetApp.
7.1 Controller Shelf Serial Number
The EF570 storage systems are shipped preconfigured from the factory (controllers have HICs and
batteries installed, and controllers are installed in the controller shelf). The chassis serial number is
printed on a white label that is affixed to the controller shelf behind the right end cap on the front of the
chassis. The SN is identified by the text “SN,” which is shown in Figure 67.
