• B
  5% (1)

Explanation

Putting the SP into Service Mode is required when an operation is so disruptive or low-level that the SP cannot be actively serving the environment during it. Reinitializing the storage system (A) wipes and resets the entire system, which demands the SP be offline and in a controlled state. Reimaging the SP (D) replaces the core operating software on the SP itself - it must be in Service Mode because the normal OS is essentially being overwritten. Replacing certain hardware components (E) requires Service Mode to ensure the SP is safely quiesced and not processing I/O while physical intervention occurs, preventing data corruption or component damage.

B (Enable SSH) is simply a configuration toggle that can be done through the management interface during normal operation - no Service Mode needed. C (Reboot SP) is a standard administrative action that can be triggered from normal mode; the reboot process itself handles the transition, so pre-entering Service Mode is not a prerequisite.

Memory tip: Think of Service Mode as required for the "3 Rs of deep intervention" - Reinitialize, Reimage, Replace hardware. These three go deeper than routine administration and require the SP to step fully out of production first.
