Configuring a Boot Device on the EMC Storage Array
a. At the OK> prompt, type "<HBA-path>" select-dev and press
ENTER to select the HBA.
Example: Suppose the path to your boot disk is
/pci@1f,4000/QLGC,qla@1/sd@0,0
Type " /pci@1f,4000/QLGC,qla@1" select-dev and press
ENTER
b. At the
OK> prompt, type 0 set-connection-mode and press
ENTER to set the HBA's topology to Loop Only.
The result is similar to this:
3. Set the adapter-loopID of your HBA to be different from the
adapter-loopids of all other Symmetrix Fibre Channel directors in
the loop. EMC recommends setting your adapter-loopid to the
same value as the Hard Loop ID parameter that you defined
when setting the driver configuration variables. (Refer to “Editing
/kernel/drv/sd.conf” on page 25.)
Example: To set your adapter-loopid to 125 (0x7d), at theOK>
prompt type 7d set-adapter-loopid and press ENTER. The result
is similar to this:
4. Reset the system for the new HBA topology and adapter-loopId
setting to take effect:
reset-all
5. Set up the boot-id for your boot HBA.
a. At the OK> prompt, type "<HBA-path>" select-dev and press
