Do not remove the card; it is used for cache recovery only. Figure 34. CompactFlash memory card CompactFlash memory card (installed/removed) IOM viewed from back (midplane-facing orientation) In single-controller configurations (supported with 2U24/2U12 chassis), if the controller has failed or does not start, and the Cache Status LED is on or blinking, the CompactFlash should be transported to a replacement controller to recover data not flushed to the disk.

    NOTE: Remove the CompactFlash memory card only if recommended by Dell EMC technical support. Transportable cache only applies to single-controller configurations. In dual-controller configurations featuring one healthy partner controller, there is no need to transport failed controller cache to a replacement controller because the cache is duplicated between the controllers, provided that the volume cache is set to standard on all volumes in the pool owned by the failed controller.
