Configuring an EMC Boot Device
Boot Time and LUN Availability
Boot time is the amount of time a storage system requires to boot.
This time is a function of the number and types of LUNs in the
storage system, and is typically less than five minutes.
If you power up a server and storage system at the same time (cold
start), the server’s extended BIOS might scan the Fibre Channel bus
before the storage system is ready to respond. If this occurs, the
server will not be able to find the boot LUN or Windows operating
system. To avoid this problem, either power up the storage system
and fabric before the server, or if the server is so equipped, set it to
delay the scan until the storage system is ready.
