■
Use any available hardware configuration interface to configure and ensure
that the configuration is what you expect. For example, on Windows servers
you can use the Hyperterminal interface to configure SCSI-to-fibre bridges.
Use the following order when you configure and verify the hardware:
■
Robot and shared drives
■
Bridges
■
Hub or switches
■
Hosts
■
If errors occur and you suspect the operating system, refer to the operating
system logs as described in your operating system documentation.
About hardware configuration guidelines
The following are hardware configuration guidelines:
■
If you use SAN hardware from multiple vendors, problems may occur. Always
use a SAN configuration and use firmware levels that the hardware vendor
supports.
■
Consult SAN device, HBA, and operating system documentation to determine
how to configure operating system tape drivers and pass-through drivers to
detect your SAN devices.
■
Check your hub timer settings.
■
Use hard arbitrated loop physical addresses rather than soft addresses. Consult
with hardware suppliers to verify the recommended usage of their products.
■
Check the firmware levels of all your Fibre Channel hardware (for example,
bridges). Use the most recent firmware level that is known to operate with
other SAN hardware devices.
■
Try to duplicate SAN issues and problems using commands and utilities on
the host operating system.
■
Test both backup and restore capabilities. Backup jobs may complete
successfully, but the data may be corrupted. For example, incorrect switch
settings may cause problems.
■
Ensure that your hardware and SAN configuration are operational and stable
before adding Shared Storage Option software.
■
Test backup and restore capabilities with dedicated tape drives before you
configure them as shared drives.
