EMC Fibre Channel with QLogic HBAs in the Windows Environment

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. The qLogic BIOS

allows a scan delay to be set in the BIOS settings. During boot, press

CTRL-Q to enter the Fast!UTIL program. Select Configuration

Settings from the menu, and then select Host Adapter Settings. Set

the

Spinup Delay parameter to Enabled. Press ESC, and save the

new settings. Press

ESC to exit Fast!UTIL, and reboot the server.
