How a Server Responds to Failure in the Boot LUN Path

Failure in the path to a SAN-based boot LUN can halt Windows in a fatal error condition. Depending on the failure, Windows may be able to transfer control to another path and continue.

Table 3-1 shows server reactions to failures in different components.

Explanations of Entries

STOP Error (fatal blue screen) — Indicates host failure and

 

 

 

 

 

chance of data corruption.

 

 

 

 

 

 

 

No boot — Cannot boot Windows.

 

 

 

 

 

 

Halt — Windows cannot recover before system has completed

 

 

 

 

 

startup. (You must reboot and follow the power-up scenario.)

 

 

 

 

Manual — Manual intervention is required to continue.

 

 

 

 

 

(Typically, initiate a LUN trespass using CLI or Manager. With

 

 

 

 

 

Manager, enable LUN Auto-Assignment in LUN properties.)

 

 

 

 

Multipath or Trespass — This automatic operation allows no

 

 

 

 

 

disruption of service. (The delay caused by this operation may

 

 

 

 

 

affect Windows stability.)
