Setting Up The External Storage Hardware; Setting Up Cluster Hardware - Compaq ProLiant DL380 Quick Install Manual

Setting Up the External Storage Hardware

IMPORTANT: The RA4100 is shipped with a single RAID controller. Each RA4100 array
used in Compaq ProLiant Clusters for SCO UnixWare 7 requires an additional, redundant
controller.
NOTE: The Quick Install automatically configures an RA4100 drive with a RAID 1 9.1-GB
UnixWare partition, even if the disk drive is larger than 9.1 GB. This partition cannot be
modified and other UnixWare disk drive partitions cannot be added to this disk drive. After
the Quick Install is completed, non-UnixWare partitions can be added up to the maximum
capacity of the disk drive, or other disk drives can be installed for additional UnixWare
partitions.
The U/300 cluster for the ProLiant DL380 server uses external storage with
the following components:
I
RA4100 storage subsystem
I
Two Compaq StorageWorks RAID Array 4000 controllers (RA4000
controller), one included in the RA4100 storage
I
Two GBIC-SWs, one in each controller
I
Two 9.1-GB or larger disk drives
I
Fibre Channel cables
To configure the external storage for the U/300 Quick Install cluster, set up the
RA4100 storage subsystem according to the following steps:
1. Follow the set-up instructions in the documentation that comes with the
subsystem to set up the RA4100.
Review the section "Fibre Channel Cable Precautions" later in this
chapter for general information.
2. Refer to the user guide for the RA4100 for disk drive RAID array
options and considerations.
3. In each array, install one redundant controller into the lower slot
(rack-mount) or into the left slot (tower as viewed from the back)
according to the following steps:
a. Disconnect the power from the storage subsystem.
b. Remove the cover from the second controller slot.
c. Rotate the board 180 degrees from the position of the top controller.
d. Insert the RA4000 redundant controller.
e. Install the GBIC-SW modules.
