4. A message displays information for the CURRENT STATUS , including:
— Link status
— Connection type (loop or fabric)
— AL_PA (Arbitrated Loop Physical Address) for loop connections, or a
hex address for fabric connections
Select [MORE] .
5. A message displays information for the CURRENT SETTINGS , including the
addressing assignment method (hard or soft) and the AL_PA for loop
connections.
Select
[MORE] .
6. A message displays information for the FUTURE SETTINGS . This allows you
to input the addressing assignment method and AL_PA that you want to
use at a later time, without affecting your current connection. (Changes to
the FUTURE SETTINGS will take effect on the next power up or board reset.)
Note For multi-level libraries, settings can be changed simultaneously
for each level of the library by changing the FUTURE SETTINGS
and then power-cycling the library.
— The default addressing is hard addressing with auto-select enabled.
Hard addressing allows you to set and maintain a fixed address, but
may result in address conflicts. Soft addressing looks for an unused
address on every power cycle, so the address might change.
Note Since AL_PAs can change with soft addressing, some backup
software applications and operating systems may have difficulty
locating the library in this mode. Check the backup software
documentation to ensure soft addressing is supported before
selecting this mode.
— If you selected hard addressing for a loop connection, select the
AL_PA (fixed address) or choose auto-select. Auto-select is an option
under hard addressing that automatically selects an available address
and then uses it as a hard address from then on.
