EMC QLA22xx, QLA23xx manual With ATF configurations

Configuring an EMC Boot Device

To trespass the LUN, follow the instructions in the EMC ControlCenter Navisphere Management software documentation for your array type. The process depends on the failover software installed:

•With PowerPath configurations, this can usually be done from the EMC ControlCenter Navisphere Management software GUI by right-clicking the desired LUN and selecting trespass. Confirm in the LUN properties that the LUN has trespassed before you return to configure the remaining Boot Port Name entries.

•With ATF configurations:

–With FC-series array core code 8.45.x, this can usually be done from the EMC ControlCenter Navisphere Management software GUI by right-clicking on the desired LUN and selecting trespass. Confirm in the LUN properties that the LUN has trespassed before you return to configure the remaining Boot Port Name entries.

–With FC-series array core code 8.44.x and earlier, you will use the atf_trespass command to trespass the boot LUN. To do this, follow the steps under Trespassing the Boot LUN Using atf_trespass on page 3-30.

Each HBA can support multiple entries; you should configure Boot Port Name entries connecting to multiple ports on both SPs for maximum redundancy in booting after a boot LUN trespass or other link failures. Refer to Table 3-1 on page 3-34 to determine your high-availability requirements.

7.When all parameters are set correctly and you have added Boot Port Name entries for all the SP ports from which you would like to attempt to boot, press ESC to return to the Fast!UTIL Options menu; then select Save Changes to save the changes you made to the current adapter.

8.Press ESC to exit the Fast!UTIL Options menu.

9.Reboot the server.
