An IOM12 module provides four SAS expansion ports for SAS shelf connectivity and includes an Ethernet port used for Alternate Control Path (ACP) management. NetApp’s E-Series cabling documentation identifies IOM12 ports 1 through 4 and describes each IOM as having four SAS-3 expansion ports.

WAFLIRON unmounts the aggregate and associated FlexVol volumes while it performs baseline checks. After they are remounted, the system serves data while WAFLIRON continues its remaining checks; for an aggregate, all associated FlexVol volumes must be mounted before data can be served.

The CFO-only setting attempts giveback only for the CFO aggregates, which include the root aggregate; it does not return all data aggregates. NetApp documents this operation as giving back only the CFO aggregates (the root aggregate).

A DCPM module is hot-swappable when the replacement is installed within the required time limit, and a same-capacity caching module can be hot-swapped on FAS9000 systems. I/O-module and NVRAM-module replacement requires taking over and halting the affected controller.

In NetApp ONTAP, a deleted volume is retained in the Volume Recovery Queue for at least 12 hours by default before it is fully deleted. The default volume-delete retention duration is 12 hours.
