In an environment where an Isilon storage node has a system failure and disk drives are likely to
be unaffected in the node, what is the preferred method for restoring cluster integrity?

A.
Engage EMC support to perform a Disk Tango process to move drives, journal, and boot
volumes to a replacement chassis

B.
Let OneFS proceed with its automatic SmartFail process to re-protect the failed node

C.
Migrate the disks from the failed node into spare drive bays on other nodes

D.
Initiate a manual SmartFail process on the node as it is not started automatically
