When two controller modules are installed in the enclosure, they must be of the same model type. When replacing both controller modules
in an operational enclosure, follow these guidelines:
1 Replace one controller as described in these instructions.
2 Wait 30 minutes: this pause ensures that the controller and its ownership of disk groups has sufficient time to stabilize. See Verifying
component operation .
3 Check the system status and event logs to verify that the system is stable.
4 Replace the partner controller as described in these instructions.
Transporting CompactFlash
This action applies to single-controller enclosure configurations only. To prevent data loss in this environment, the CompactFlash must be
moved from the failed controller to the new controller module.
CAUTION: Do not transport CompactFlash in a dual-controller environment. Doing so could cause data corruption.

Confirm that transporting CompactFlash is the appropriate action to take as discussed in the ME4 Series Storage System Deployment
Guide . Refer to Figure 54. CompactFlash memory card location when performing the step-procedure below.
Before you begin any procedure, see ESD precautions .
1 Locate the CompactFlash memory card at the midplane-facing end of the failed controller module.
2 Grip the CompactFlash memory card and carefully pull it from the slot in the failed controller module.
3 Label the CompactFlash memory card as Data, and set it aside for safekeeping.
4 Locate the replacement controller module, and carefully remove its installed CompactFlash memory card.
a Take care not to confuse this diskette with the one labeled Data.
b Insert this CompactFlash memory card into the failed controller module.
5 Align the CompactFlash memory card labeled Data for insertion into the replacement controller module—then insert it into the slot—
and push it forward until seated in place.
