Installing Peripheral Components
In this step, you will install peripheral components that are necessary for the servers to operate in a cluster
configuration.
NOTE The standard HP NetServer LH Pro is equipped with 32 to 64 MB of memory. Cluster operations require a
minimum of 128 MB of memory. If you have a standard system, you will need to add additional memory to each of
your HP NetServer LH Pros to bring them up to the minimum requirement for cluster operations.
To install peripheral components at Systems A and B:
1. If necessary, install additional main memory according to the instructions that come with the memory. (See
Note above.)
2. Install the system disk.
HP recommends use of a hot swap drive. Install it in the upper center slot of the HP NetServer LH Pro card
cage (SCSI address 0).
3. Install two LAN cards (HP part number HP J3171A) in each System as follows.
Installing the cards in other slots may cause IRQ conflicts.
4. Remove the fan and install the redundant power supply.
Follow the instructions included with the power supply. Pay close attention to the lower left corner of the
power supply to ensure it doesn't pinch, snag, or otherwise interfere with the SCSI cables coming from the
main system board.
NOTE
If you are using array model LH Pros for your cluster, proceed to the section below, "Recabling the Array
Model LH Pro". If you are using non-array model LH Pros for your cluster, skip the next section and proceed with
the "Installing the HP NetRAID Adapter" section.
Recabling the Array Model LH Pro
The array model LH Pro is cabled internally so that the NetRAID card uses the drives in the internal hot swap cages.
To use an array model LH pro in a cluster, it must be recabled as a non-array model, so the internal hot swap cages
are connected to the embedded SCSI A and B controllers, and the NetRAID card may be connected to the external
shared storage.
To recable an array model LH Pro to a non-array model, refer to the reference label on the right side of the computer
and perform these steps:
1. Remove the C14 cable that connects the lower hot swap cage to the upper cage. Set this cable aside.
2. Remove the adapter that connects the C22 cable from SCSI A to the C11 cable that goes to the CD-ROM
drive. Set the adapter aside.
3. Connect the free end of the C22 cable that comes from SCSI A to the 68 pin input connector on the top hot
swap cage. The input connector is on the right when the cage is viewed from the back.
