Booting from the array 57
No existing MPE/iX boot disk available and disk
array is direct Fibre Channel connected
If you have no boot disk available and the disk array is direct Fibre Channel
connected, you can use the MAPPER2 utility while the system is booted
from the SLT tape on the alternate boot path. MAPPER2 will locate and
display the boot menu I/O paths for the directly Fibre Channel attached disk
arrays. You choose the desired disk array LUN from the MAPPER2 output
to become the new MPE/ix Ldev 1 boot disk, and then use the MAPPER2
I/O path to set the system’s primary boot path for loading the OS.
Follow this procedure and example to use MAPPER2 to set the boot
path:
For brevity, only an excerpt of the MAPPER2 output is shown.
1. Boot the system from the SLT tape on the alternate boot path.

3. Choose the desired disk array LUN as the new boot disk and record its
I/O path from MAPPER2. In the following example, LUN 2 of the disk
array is used at path 0/6/0/0.8.0.102.0.0.2.
