Adapter Compatibility
This section explains adapter compatibility considerations for
performing OLA and OLR.
Online Addition (OLA) You can add multiple adapters at the same
time. While adding an adapter online, the first issue you must resolve is
whether the new adapter is compatible with the system. Each
OLAR-capable PCI slot provides a set amount of power. The replacement
adapter cannot require more than the available power.
The adapter must also operate at the bus frequency of the slot. A PCI
adapter must run at any frequency lower than its maximum capability,
but an adapter that can operate at only 33 MHz will not work on a bus
running at 66 MHz. The SCSI A6828A or A6829A HBA operates at
66MHz. The rad command provides information on the bus frequency
and power available at a slot, as well as other slot-related data.
If your system has one or more slots that support OLAR, and you want to
use OLA to install the A6828A or A6829A in one of those slots, install the
adapter in your HP-UX system according to the procedure described in
the “Managing PCI Cards with OLAR” chapter of the Configuring
HP-UX Peripherals manual.
After you add a new A6828A or A6829A adapter, SAM tries to locate the
SCSI c8xx driver. If SAM is unable to locate the driver, you cannot use
the new adapter until you install the driver, because driver installation
requires a system reboot. If SAM locates the driver, it determines
whether the new adapter is functional. If the adapter is not functional,
SAM displays an error message.
Online Replacement (OLR) While replacing an interface adapter
online, the replacement adapter must be identical to the adapter being
replaced, or at least be able to operate using the same driver as the
replaced adapter. This is referred to as like-for-like replacement. You
should adhere to this because using a similar but not identical adapter
can cause unpredictable results.
For example, a newer version of the target adapter that is identical to the
older adapter in terms of hardware might contain an updated firmware
version that may potentially conflict with the current driver. In addition,
both the old and new adapters must have the same PCI identifiers
(subsystem ID and device ID).
