Give back only the CFO aggregates with the storage failover giveback

command.
◦ If the command fails because of a failed disk, physically disengage the failed disk, but leave the
disk in the slot until a replacement is received.
◦ If the command fails because of an open CIFS session, check with the customer on how to close
out CIFS sessions.
Terminating CIFS can cause loss of data.
◦ If the command fails because the partner is "not ready", wait 5 minutes for the NVMEMs to
synchronize.
◦ If the command fails because of an NDMP, SnapMirror, or SnapVault process, disable the
process. See the appropriate Documentation Center for more information.
