Configuring the Library for Arbitrated Loop (AL) Environments:
CAUTION Do Not use soft addressing on HP-UX.
1. From the library front panel, select the
Fibre Channel menu.
2. Select the level where the FC card you want to configure is located
using the
[+] or [-] keys.
3. Select
[OK].
4. A message displays the addressing assignment method and AL_PA
(Arbitrated Loop Physical Address). Select the addressing type (hard
or soft).
• The default addressing is hard addressing (Recommended) 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. Since AL_PAs can change with soft
addressing, some backup software applications may have difficulty
locating the library in this mode. Check the backup software
documentation to ensure soft addressing is supported before
selecting this mode.
5. If you select hard addressing, select the
[AL_PA] (fixed address) or
choose
[auto-select]. Auto-select is an option under hard addressing
that picks an available address and then uses it as a hard address
from then on.
6. Select
[OK] when complete to save the changes. A message confirms
your changes. You can also select
[Quit] to exit the Fibre Channel
Configuration
menu and not save the changes.
Setting the Date and Time
(Necessary during initial installation or after powering-off):
1. Select the
[Set Date & Time] menu.
2. Use the
[+] or [-] key to select the year, month, and day. Use the right
arrow to scroll to the next entry.
3. Set the hour and minutes (00:00:00) using the
[+] or [-] keys. Use the
right arrow key to scroll to the next entry. The seconds are
automatically set at 00.
