Introduction
1.1
How to Use this Guide
This user’s guide is for the SANblade QLA4000-DEV iSCSI host bus adapter (HBA).
This guide contains installation instructions for the hardware (QLA4000-DEV),
supported software drivers, and the SANblade Control IX GUI. Install these
components in the following order:

1.2
General Description
The QLA4000 is an iSCSI HBA that provides PCI connectivity to SCSI using the
iSCSI protocol. This release of the QLA4000 implements draft 0.8 of the IETF iSCSI
standard, which creates a new industry standard SAN technology based on internet
protocols: TCP/IP. Updates to later iSCSI drafts will be available for downloads to
the HBA. iSCSI enables new IP based SANs, which are similar to Fibre Channel
SANs, as well as a new set of storage applications, for example, remote storage.
The QLA4000-DEV implements the complete protocol stack, including TCP/IP, on
the HBA and off-loads the host of any I/O protocol processing. Off-loading the host
frees the system to perform other tasks and deliver optimum total system
performance. The QLA4000-DEV handles complete SCSI transactions, iSCSI,
TCP/IP and Ethernet.
The QLA4000-DEV is a development product and is not intended for mass
distribution.

Installation in the Computer
CAUTION! The QLA4000-DEV contains parts that can be damaged by ESD.
Before handling the QLA4000-DEV, use standard methods to
discharge static electricity. Keep the QLA4000-DEV in the antistatic
bag until you are ready to install it. Place the HBA on the bag when
you examine or configure it. Retain the bag for future use.
Perform the following steps to install the QLA4000-DEV in your PC:
1. Check the motherboard and make any configuration changes necessary to
accommodate the QLA4000-DEV.
The QLA4000-DEV is self-configuring; however, some motherboards
require manual configuration. For example, some systems have a PCI
Device Configuration menu in the motherboard setup BIOS where you
must enable HBAs, bus master slots, and IRQ levels. If the motherboard
supports triggering, use level triggering for the QLA4000-DEV. See the
documentation supplied with your computer, or contact your computer
dealer to determine if your motherboard requires configuration.
2. Power down the peripherals, then the computer.
3. Remove the computer cover and save the screws.
4. Choose any PCI bus slot that supports bus mastering. Most motherboards
automatically assign an IRQ level and interrupt line; if your motherboard
does not, you must assign the IRQ level and use interrupt line A for this slot.
NOTE:
■ Some motherboards have two kinds of PCI bus slots: master
and slave. The QLA4000-DEV must be in a PCI bus master
slot. (Some motherboards have PCI bus master slots that are
shared with onboard devices. QLA4000-DEVs do not work in
shared slots.)
■ PCI connectors vary among system HBA manufacturers. The
QLA4000-DEV is a 64-bit PCI device that can function in a 32-bit
PCI slot; the slot conforms to the PCI specification (the rear
edge of the PCI slot is notched). If you try to install the
QLA4000-DEV into a PCI slot that does not conform to the PCI
specification, you may damage the QLA4000-DEV.
■ PCI and PCI-X slots look the same. If the PC contains both PCI
and PCI-X slots, refer to the PC manufacturer’s instructions to
determine the slot type.
■ The QLA4000-DEVs are designed and tested to operate at PCI
bus speeds of up to 66 MHz.
5. Remove the slot cover for the slot in which you will install the QLA4000-DEV.
6. Place the QLA4000-DEV into the slot. Carefully press the HBA into the slot
until it seats firmly.

5.3.3
Configuring Targets
After configuring the QLA4000-DEV, you can enter iSCSI targets you want to
discover. Start SANblade Control IX (see step 5 in section 5.2), select your host and
HBA, then click the Target Settings tab. When the QLA4000-DEV arrives from the
factory, there are no targets listed. Add iSCSI targets by either entering specific
iSCSI target information (IP address and iSCSI name, see section 5.3.3.1) or by
entering an IP address and discovering the devices behind that address (see
section 5.3.3.2).
5.3.3.1
Configuring Specific Targets
To configure a specific iSCSI target, follow these steps:
1. Start SANblade Control IX, select your host and HBA, then click the Target
Settings tab.
2. Click the first available line under IP Address (see figure 5-2).
3. Enter the IP address of the target to which you want to connect.
4. Enter the iSCSI name of the target.
5. Enter other targets as desired.
6. Click Save. The QLA4000-DEV does the following:
a. Resets (reboots the HBA only)
b. Connects to the target
c. Queries the target through a SendTargets command
d. Discovers all devices allowed by the target
e. Makes these new targets available on the SANblade Control IX Target
Settings tabbed page
7. Restart the host PC for the operating system to recognize the new targets.
8. The QLA4000-DEV restarts and attempts to connect to the configured
targets.
5.3.3.2
Configuring Using Discovery
Use the discovery mechanism to configure a target that supports and responds to
the SendTargets command by following these steps:
1. Start SANblade Control IX, select your host and HBA, then click the Target
Settings tab.
2. Click the first available line under IP Address (see figure 5-2).
5-8 IS0053301-00 A
5 – SANblade Control IX
3. Enter the IP address of the target to which you want to connect. This target
must support the SendTargets command.
4. Leave the iSCSI Name field blank.
5. Click Save. The QLA4000-DEV does the following:
a. Resets (reboots the HBA only)
b. Connects to the target
c. Queries the target through a SendTargets command
d. Discovers all devices allowed by the target
e. Makes these new targets available on the SANblade Control IX Target
Settings tabbed page
6. Restart the host PC for the operating system to recognize the new targets.
The discovery method is an excellent timesaver for finding and entering iSCSI
targets. You can use this method to find all available targets, delete targets you don’t
want, and then have access only to the remaining devices. This method prevents
you from having to enter iSCSI names for each target. In the following example,
there is an iSCSI target at IP address 10.14.64.150. Behind this target are two
available drives with iSCSI alias’ Drive1 and Drive2.
Operation
1. On the Target Settings tabbed page, under IP Address, enter IP address
10.14.64.150.
2. Leave the iSCSI Name field blank.
3. Click Save.
4. Click the Target Settings tab.
The following three targets appear:
❑ IP address 10.14.64.150
❑ IP address 10.14.64.150 with iSCSI alias Drive1
❑ IP address 10.14.64.150 with iSCSI alias Drive2
5. Restart the host PC for the operating system to recognize the new targets.
CAUTION! The iSCSI port number defaults to 3260. Do not change this number
unless required by the configured target.
