Installing a QLogic adapter and driver for Windows 2000 or 2003

This section describes how install a QLogic adapter card on a Windows 2000 or 2003 host and provides the recommending settings for the adapter.

1. Install the QLogic adapter card in the host system.
2. Connect the cable to the storage unit port.
3. Install and configure the adapter driver. See the installation instructions that are provided by your host adapter vendor for specific adapter and adapter driver instructions. Go to Downloading and installing a host adapter driver or to http://support.qlogic.com/support/oem_ibm.asp.
4. Restart the host.
5. Press Ctrl+Q to get to the FAST!Util menu.
6. Use FAST!Util to set the parameters to the values that are listed in Table 1.
   Note: Installing a QLogic adapter and driver for Windows 2000 or 2003 contains settings for the QLogic QLA23xx, QLA246x, and QLE246x adapters.

   Table 1. Recommended settings for the QLogic QLA23xx, QLA246x, and QLE246x adapters for Windows 2000 or 2003

   Parameters	Recommended settings
   Basic Input/Output System (BIOS)	Disabled
   Frame size	2048
   Loop reset delay	5 (minimum)
   Adapter hard loop ID	Disabled
   Hard loop ID	0
   Execution throttle	100
   Fast command posting	Enabled
   >4 GB addressing	Disabled (for 32-bit systems)
   LUNs per target	0
   Enable LIP reset	No
   Enable LIP full login	Yes
   Enable target reset	Yes Note: Enable LIP reset, Enable LIP full login, and Enable target reset parameters control the behavior of the adapter when Windows® tries to do a SCSI bus reset. You must perform a target reset operation to make cluster failovers work. Use the SCSI bus device reset option to clear SCSI reservations.
   Login retry count	20 (minimum)
   Port down retry count	20 (minimum)
   Driver load RISC code	Enabled
   Enable database updates	No
   Disable database load	No
   IOCB allocation	256
   Extended error logging	Disabled (You might want to enable this parameter if you use the debugging function.)
   Type of connection	Loop only Point-to-point Loop preferred (If you cannot use arbitrated loop, then default to point-to-point.) Point-to point, otherwise loop only (If you cannot use point-to-point, default to arbitrated loop.) Notes: If you connect the storage unit directly to the host system, the option that you select must match the port connections on the storage unit. If you connect through a switch, the options do not need to match the port connections because the storage unit is point-to-point. The appropriate host adapter on the server must also support a point-to-point connection on a direct connection. If you use adapter cards from different manufacturers, they will not function properly in a direct point-to-point connection. This is not true if you connect through a switch because the storage unit is point-to-point.

7. Restart the server.
