Installing the HBA into Your Server

Installation and Configuration
4. Label each cable to identify the HBA and the storage/switch/hub
port to which it connects.
5. After connecting all HBAs in the server, power up the server.
Special Installation Sequence for Stratus ftServers and EMC CLARiiON Arrays
A specific installation sequence is required when installing QLogic
HBAs with the Stratus ftServers and EMC CLARiiON
®
storage.
Failure to follow this sequence may result in a
STOP: 0X0000007B
bugcheck error when booting the Stratus server for the first time
when connected to EMC CLARiiON storage.
With the Stratus ftServer, if the HBA detects EMC CLARiiON array
targets but no accessible LUNs, it prevents the Stratus server from
booting. In this configuration, the Stratus ftServer attempts to boot
from the array, instead of booting from the internal boot drive.
To avoid this issue before storage is correctly assigned, either boot the
Stratus ftServer before connecting the fibre cables to the HBAs or, if
connected to a fabric, disable the HBA ports on the switch before
booting the ftServer.
After the system has booted, connect the cables or reenable the switch
ports. Verify that the HBAs are logged in to the EMC CLARiiON
array; then stop and restart the Navisphere agent on the ftServer host.
This will register the HBAs with the CLARiiON array and allow the
HBA to properly detect the available LUNs.
Matching the HBA with the Correct PCI Slot
When choosing an HBA into your server, it is important to know
which HBA is compatible with your server’s PCI/PCI-X/PCI
Express slots. Certain HBA models have specific voltage
requirements or physical limitations that allow them to only work in
specific slots.
Servers today have several different bus slot types for accepting
HBAs. PCI, PCI-X, PCI-X 2.0, and PCI-Express.
PCI slots can be 32-bit and 64-bit (denoted by their 124-pin or 188-pin
connectors.) These slots have plastic “keys” which prevent certain
HBAs from fitting into them. These keys work with the cut-out
notches in the HBA edge connecter so that only compatible HBAs
will fit into them. This is done because of the voltage characteristics
of the HBA. Inserting a 3.3v HBA into a 5v slot would cause severe
damage to both the HBA and the server. Therefore, the slot keys
