8 Upgrading to an HP NetRAID-3Si or
HP NetRAID-1Si Adapter
This chapter explains how to replace an existing HP NetRAID Series adapter
with an HP NetRAID-3Si or HP NetRAID-1Si adapter. When you replace one
adapter with another, you do not need to worry about data compatibility. Data
created using any HP NetRAID Series adapter is compatible with any other
HP NetRAID Series adapter. Further, data written using an HP NetRAID Series
adapter operating in I
2
O mode is compatible with data written using an
HP NetRAID Series adapter operating in non-I
2
O mode (conventional mass
storage mode), and vice versa.
NOTE A new adapter must have channels that are equal in number or
greater than the adapter it is replacing. Do not replace an
HP NetRAID-3Si adapter (using three channels) with a
NetRAID-1Si adapter (which can control only one channel).
After replacing an HP NetRAID-3Si or NetRAID-1Si adapter, you need to:
• Back up your data
• Load the appropriate driver
• Insert the HP NetRAID-3Si or HP NetRAID-1Si adapter and recreate the
configuration
CAUTION HP NetRAID Series Accessory boards are not hot pluggable.
Unplug HP NetServer power cord(s) before installing a
HP NetRAID Series board.
• Restore your data from backup
Back Up Your Data
Back up all data on the drives controlled by the adapter that will be removed.
