Looking at Adapter Installation
Installation can be performed in one of two ways:
• Use the OLAR (On Line Add/Replace) capability (HP-UX 11i). Refer
to “Install Using OLAR (HP-UX 11i)” on page 20.
• Power down the system and then add or replace the HBA. Refer to
“Install/Replace With System Powered Down” on page 25.
The method you choose will depend on your situation, the card you are
installing, and your requirements.
Before You Start
For safe and proper installation, do the following:
Look through the task list below to get an overall idea of the steps to
perform.
1. Determine whether or not you can use the OLA/R (On Line Addition
[and] Replacement) method to install the HBA (see “Install Using
OLAR (HP-UX 11i)” on page 20).
2. Remove the SPU/system cabinet cover on the system to access the
PCI slots. Refer to the system server manual for accessing PCI slots.
3. Insert the host bus adapter.
4. Connect the SCSI peripherals.
5. Terminate the external SCSI bus.
6. Set the peripheral SCSI IDs.
7. Make any configuration changes.
8. Replace the SPU/system cabinet cover.
The SCSI host bus adapter acts on the server’s behalf as the host to the
suite of SCSI peripherals. Each chain of SCSI peripheral devices and
their host bus adapter work together and are referred to as a SCSI bus.
Each channel on your SCSI host bus adapter can act as host for up to 15
peripheral devices (depending on the SCSI bus speed), not including the
adapter itself.
