Setting the Time, Network Address, and Library Parameters
4-6 StorageTek SL150 Modular Tape Library User's Guide
■ If you control the library using a version of Oracle StorageTek ACSLS software
that supports the Drive Element Addressing option, set this value to Address
All Drive Slots (Recommended).
For support information, consult the ACSLS documentation library for your
version of the software.
■ If you control the library using a version of Oracle StorageTek ACSLS software
that does not support the Drive Element Addressing option, set this value to
Address Only Installed Drives.
For support information, consult the ACSLS documentation library for your
version of the software.
■ If you are installing a new library, set this value to Address All Drive Slots
(Recommended).
This option supplies addresses for all drive bays, so that host system drive
assignments do not need to be remapped when drives are subsequently added
or replaced.
■ If you are upgrading an SL150 library that does not currently assign addresses
to empty drive bays, set this value to Address Only Installed Drives.
In this situation, previously installed drives already have addresses that are in
use by host systems. You do not want to discard the existing addresses and
start over. Entering Address Only Installed Drives retains the current
addresses and assigns the next address in sequence to the new drive.
■ If you are replacing a failed drive in an SL150 library that does not currently
assign addresses to empty drive bays, consider setting this value to Address
All Drive Slots (Recommended).
In this situation, some disruption is inevitable. At least some addresses are
likely to change and some hosts will have to be remapped to the new
hardware. If you are willing to do all of the host reconfiguration now, you can
select Address All Drive Slots (Recommended) and avoid this situation in the
future.
3. To enable library controlled automatic drive cleaning, open the Drive Auto Clean
list control and select On.
Note that you must also reserve one or, preferably, two system slots for cleaning
media when you enable the Drive Auto Clean feature. See
"Selecting a Cleaning
Strategy" on page 3-1 for more information.
4. To use another drive cleaning method, open the Drive Auto Clean list control and
select Off.
See "Selecting a Cleaning Strategy" on page 3-1 for more information.
5. To expand the mailslot of an already configured library, move any cartridges that
reside in the physical mail slot and/or the righthand magazine to host-controlled
storage slots.
When you expand the mailslot, the fifteen storage slots in the righthand magazine
of the base module become cells in the shared mailslot. Moving cartridges into
slots that remain under host control beforehand keeps the host application's
catalogs consistent. More importantly, in partitioned libraries, it keeps each host
application's data volumes segregated. Applications are thus less likely to
encounter and inadvertently overwrite unrecognized volumes from other
partitions.
