Software Version 8.7A for Novell NetWare
CAUTION: Before attempting a SCSI-2 to SCSI-3 migration, it is extremely important
that all data be backed up and that units be available for remapping CCL data. In
addition, ensure that all redundant storagesets are in normal (non-reduced) mode.
When migrating from SCSI-2 to SCSI-3, the controller checks for controller unit D0
and does not change modes until D0 (at all presented offsets) is deleted. One or more
LUNs are lost after the mode change. If you are planning to move from SCSI-2 to
SCSI-3, back up your data first. The data in LUN 0 (and any other offsets that map to
LUN 0) that was used in SCSI-2 requires that the data be moved to a different LUN. It
may be necessary to retrieve this data from a backup.
IMPORTANT: If multi-bus failover configurations or server clustering are employed in the
environment, there may be additional considerations regarding CCL usage during SCSI
migration procedures. Please see your multi-bus failover or server clustering documentation
prior to implementation.
In addition, there may be OS-based limitations on SCSI-3 usage to consider, particularly in
down-level versions of your OS. Please review your OS documentation prior to migration.
For more information, see the “What is the Command Console LUN?” and “Assigning
Unit Numbers Depending on SCSI_VERSION” sections of Chapter 1 in the HSG80
ACS Solution Software Version 8.7 Installation and Configuration Guide.
Operating Constraints
This section describes the operating constraints for ACS Version 8.7. An operating
constraint is a limitation placed on the operation of the controller. Other constraints on
host adapters or other system components may also apply. Keep these constraints in
mind to avoid problems and to help achieve the maximum performance from your
controller. See the documentation that came with your host server for more details.
Controller Configuration with NetWare
StorageWorks Command Console (SWCC) provides a graphical user interface that
can be used to configure and monitor your storage system. Use of SWCC is
recommended, but not required. Solution Software Version 8.7A for NetWare no
longer ships with SWCC but the controller can be configured in other ways. There are
three options available for configuring HSG80 controllers on NetWare:
• Access the CLI utility through the serial port and execute CLI commands needed
for configuration. See the HSG80 Array Controller ACS Version 8.7 CLI
Reference Guide included with this kit for configuration commands.
