6.8.4 Setting Up the HSG80 Array Controller for Tru64 UNIX
Installation
This section covers setting up the HSG80 controller for operation with Tru64
UNIX Version 5.1A and TruCluster Server Version 5.1A.
The steps described here apply to both fabric and arbitrated loop
configurations. However, arbitrated loop requires specific settings for the
port topology and AL_PA values. If this is an arbitrated loop configuration,
follow the steps described here, taking note of the difference in the port
topology setting. Then see Section 6.8.4.1 for additional information.
For more information on installing the HSG80, see the Compaq StorageWorks
HSG80 Array Controller ACS Version 8.5 Configuration Guide or Compaq
StorageWorks HSG80 Array Controller ACS Version 8.5 CLI Reference Guide.
To set up an HSG80 for TruCluster Server operation, follow these steps:
1. If they are not already installed, install the HSG80 controllers into the
RA8000 or ESA12000 storage arrays.
2. If the external cache battery (ECB) is used, ensure that it is connected
to the controller cache modules.
3. Install the fiber-optic cables between the KGPSA and the switch or hub.
4. Set the power verification and addressing (PVA) ID. Use PVA ID 0 for
the enclosure that contains the HSG80 controllers. Set the PVA ID to
2 and 3 on expansion enclosures (if present).
____________________ Note _____________________
Do not use PVA ID 1.
With Port-Target-LUN (PTL) addressing, the PVA ID is used
to determine the target ID of the devices on ports 1 through
6 (the LUN is always zero). Valid target ID numbers are 0
through 15, excluding numbers 4 through 7. Target IDs 6
and 7 are reserved for the controller pair, and target IDs 4
and 5 are never used.
The enclosure with PVA ID 0 will contain devices with target
IDs 0 through 3; with PVA ID 2, target IDs 8 through 11;
with PVA ID 3, target IDs 12 through 15. Setting a PVA ID
of an enclosure to 1 would set target IDs to 4 through 7,
generating a conflict with the target IDs of the controllers.
5. Remove the program card ESD cover and insert the controller’s program
card. Replace the ESD cover.
