Swap pi n g a H ost Adapt er

Swapping a 7800 Family host adapter for a non-7800 Family host adapter is similar to the procedure for adding a host adapter. The important distinction is that you make all software configuration changes while Windows NT is running and before you make the hardware changes.

If you do not install the driver that comes with the

Note:

new host adapter, it may result in a Windows NT boot failure.

To swap adapters, follow these steps:

Install the driver fo r the 7800 Family h ost adapt er by following

the steps in Installing the Driver When Wind ows NT is Already Installed on page 2-5.

It is not essential to remove the device driver for the h ost adapter you are replacing. Windows NT dynamically detects the absence or presence of host adapter hardw are, and no problems should arise if you leave the existing device driver installed. You may remove the device driver later, after you have successfully rebooted Wi nd ows NT. However, if you leave the driver installed, the system alerts you with an error message of the extra device driver every time you boot. See Remov ing a Host Ad ap ter on page 2-12.

Once the new device driver is installed, shu t down Windows

NT and replace the existing host adapter with th e 7800 Family host adapter.

some drive letter assignments may change from the previous configuration.

Troubleshooting

Problems and Solutions

What is a miniport driver, and how do I make sure that the miniport driver for my host adapter is installed correctly?

Miniport drivers are 32-bit protected mode device drivers used by Windows 95 to cont rol host adapters and devices. Windows 95 includes a set of miniport drivers f or various SCSI host adapters .

If your 7800 Family host adapter is already installed, th e adapter ’s miniport driver is automatically installed and configured during Windows 95 installation. Follow the instructions listed in Installing the Driver When Windows 95 is Already Installed on page 3-2 to ensure that the miniport driver is updated.

To make sure the driver is installed correctly in systems running Windows 95, open the Control Panel, double-click on System, and click the Device Manage r tab. Then double-click the SCSI Controllers icon; you should see the model name of the SCSI host adapter(s) installed in your system.

What if there is no SCSI Controllers icon under Devi ce Manager, or the model name of the host adapter does not appear under Device Manager?

If the SCSI Con trollers icon or your host ad ap te r’s model name do not appear in the Device Manager, follow thes e steps:

Open Control Panel and double-click the Add New Hardware icon. Le t Windows search for the host adapter by sel ecting Yes on the second screen of the Add New Hardware Wizard.

If Windows does not detect the adapter, run the Add New Hardware Wizar d again. This time, select No on the second screen of the wizard, then select SCSI Controllers on the next screen.

Insert the 7800 Family Manager Set diskette for Windows 95 into your floppy drive.

Select the model of your 7800 Family host adapter, and then click the Have Disk button.

Enter a:\win95 or b:\win95 as the location to copy the file from.

Click OK. The driver is copied and your system is updated.

Page 40

Adaptec 7800 Family Manager

You must restart your computer for the changes to take effect.

What if a yellow exclamation mark or a red X appears in Device Manager in front of my host adapter.

This means th e re is some kind of resour ce p roblem. First, see if the names of any host adapters appear that are not actually instal led in your computer. If so , se lect the n a me a nd click Remove.

If a red X appears i n front of your host adapter name, r emove all the host adapter references under SCSI Controller s and run Add New Hardware, as described in the previous question/answer.

If a yellow exclamation point appears in front of your host adapter name, the resources that the driver uses probably do not match the resources used by the hardware. Double-cl ick the host adapter name, then click on the Resource tab. Deselect the Use Automatic Settings b ox and edit the re sou rces (Interrupt Req uest, Dire ct Memory Access, etc.) so they match those used by the host adapter. If the problem still remains, there is probably a hardware resource conflict betw e e n th e ho st adapt e r a n d o th er hardwa re in your computer. You can fix this by changing the hardware resource settings. (See your hardware documentation.)

What do I need to do if I change or upgrade my host adapter?

Open the Control Panel, double-click on System, and click the Device Manager tab.

Double-click the SCSI Co ntroll ers icon, select the name of the old host adapter, and click Remove.

If I am running under Windows 95, do I need lines for the Adaptec real mode ASPI drivers and mscdex in my config.sys and autoexec.bat files?

Usually, you do not need to use these Real mode ASPI drivers, because the new Windows miniport drivers support most SCSI host adapters and SCSI devices. However, you need to load the drivers (including

mscdex

, if you ha v e a CD-ROM drive) if any of t he following is true:

You are running in MS-DOS mode a nd need to access your CD-ROM dr ive .

■

You are using a scanner or another SCSI device with

Optimizing Performance

The Adaptec 7800 Family SCSI Bus Master firmware increases the SCSI performance of the Adaptec 7800 Family host adapters under multitasking environments. The firmwar e uses a paging mechanism to handle up to 255 simultaneous SCSI commands. The sequencer can simultaneously manag e up to 128 tagg e d, or 1 non tag g ed, SCSI commands for each SCSI device, up to a limit of 255 SCSI commands. The firmware can queue as many commands as the operating system is able to send to the host adapter. To set this feature, enter the following command:

max_tags=

In general, a low number of max_tags gives be tter sequent i a l performance, and a h igh number a better random performance.

Note:

problems leading to deactivations with some drives.

A large number of max_tags can also ca use starvation

Using SCO UNIX and the Host Adapter

This section contains useful information on using SCO UNIX and your host adapter.

Using Multiple Host Adapters

If you are ad ding an addit ional 7800 Family h ost ad apter to a sys tem with a 7800 Family host adapter already installed, follow the instructions in the SCO UNIX documentation for adding devices using the mkdev command. When the system asks for the host adapter prefix, type alad or blad and press Enter.

Changing the Boot Disk

If you are changing the boot device from a non-SCSI har d disk to a SCSI hard disk attached to an Adaptec 7800 Family host adapter, you must reinstall SCO UNIX.

If you are already booting from a SCSI hard disk and wish to boot from a SCSI hard disk attached to an Adaptec 7800 Family host adapter, you may elect to either reinstall SCO UNIX with the new driver (see Installing the Dri ver Wh en Inst alling SCO UNIX on

6-10

Page 89

SCO UNIX Installation

page 6-2), or update SCO UNIX with the new driver (see Installing the Driver When SCO UNIX is Already Inst alle d on page 6-5).

Using Wide SCSI Host Adapters and Devices

SCO UNIX 3.2v4.2, SCO ODT 3.0, and SCO OpenServer 3.0 support SCSI IDs 0 to 7; SCSI IDs greater than 7 are not recognized. If your 7800 Family host adapte r is a Wide SCSI adapter, only 7 SCSI devices (SCSI ID 0 to 6, with the host adapter se t at SCSI ID 7) can be attach e d an d sup ported.

SCO OpenServer 5 supports SCSI IDs 0 to 15. If your 7800 Family host adapter is a Wide SCSI adapter, up to 15 SCSI devices can be attach e d an d sup ported.

Using Tunable Parameters for the alad Driver

For SCO UNIX, some parameters are defined in the following file:

/etc/conf/pack.d/alad/space.c

These parameters can be tuned for the modif y in g the parameters to take effect. The following section describes how to set the tunable parameters.

Problems and Solutions

In SCO OpenServer 5, my system hangs after I have installed the driver and rebooted the system.

If you are installing OpenServer 5, version 5.0.0, you may have to install the SCO OpenServer 5 keyboard patch (available from the SCO Web site or BBS) at the same time you install the

alad325

driver. To install the keyboard patch at the same time you install SCO OpenServer 5 and the

alad325

driver, type the foll owing

instead of the ahslink command described above:

defbootstr ahslink = “kbp alad325”

Follow the onscreen instruct ions to inser t the SCO keyboard patch diskette (kbp) and the 7800 Family Ma na ger Set diskette for SCO UNIX when instructed.

I have problems using my SCSI devices.

During bootup, check to see if the BIOS messages for your primary 7800 Family host adapter lists all installed SCSI devices. I f some or all devices do not appear , check the following (also check your host adapter’s User’s Guide for additional tr ou b leshooting inf ormation):

■

Are all SCSI devices powered?

■

Are all SCSI bus cables and power cables properly connected?

■

Do the host adapter and all devices on the SCSI bus have unique SCSI IDs?

■

Are all devices on the SCSI bus terminated properly?

■

Do you have an older SCSI peripheral installed? Some older SCSI peripherals, especially CD-ROM drives, do not properly respond to synchronous negotiation. As a result, these periph erals m ay lo ck or reset th e SCS I b u s. To solve this problem, turn off synchronous negotiation for this device ID through the SCSI Se lect utility for the host adapter. See the host adapter’s User’s Guide.

My computer does not recognize my host adapter.

During bootup, check to see if the BIOS message for your primary 7800 Family host ad apter appea rs. If the mes sages do not appear, the host adapter may not be properly configured; check the following:

■

The 7800 Family host adapte r suppor ts level-triggered interrupts and can share the same interrupt with another 7800 Family host adapter or PCI hardware that also supp orts leveltrigge re d in t er ru p t s. Check your ho st adap te r’s User ’s Guide and your computer documentation for details in configuring IRQs and other parameters in the system CMOS setup.

■

The Boot host adapters should be installed into the lowest PCI Device number. The Device number is determined by the slot number on the PCI bus.

To find out the Device number of your 7800 Family host adap te r ( s) , run the SCS ISelect utility (by pressing a key combination displayed onscree n at bootup). Lo ok on the first screen of SCSISelect in the upper right hand corner for Bus:Device xx:xxh (given in hex).

If the Device number is high, power

the computer , move

OFF

the 7800 Family host adapter to a PCI slot at the other end of the motherboard, and r erun SCSISelect to see if the number is lower.

The host adapter LED lights during activity. This light helps to determine which adapter SCSISelect displays information for. Refer to your system doc u me ntati on fo r further d e t ai l s on determining the PCI slot number and slot number order in the system.

I am having problems booting the computer from a SCSI drive.

Make sure your host adapter is ins tal l e d and configured correctly, as described in your host adapter’s User’ s Gui de . Her e are some of the things you sh ould check:

If both SCSI and non-SCSI (e.g., IDE) disk drives

Note:

are installed, then the non-SCSI disk drive is always the boot device.

– Be sure the Drives setting (in your computer ’s CMOS setup

program) that corresponds to the SCSI boot drive is set to None or No Drives Installed, as is required for SCSI hard disk drives. (See your computer’s documentation.)

– Be sure the Host Adapter BIOS setting in the SCSISelect

utility is enabled.

– Be sure the Extended BI OS Translation feature i n the

SCSISelect utility is enabled. The host adapter BIOS automati cally selec ts the correc t translation method as needed.

■

Examine the SCO UNIX

mscsi

file to make sure the correct

host adapter and devic e are spec ifi ed as the boot entr y. The boot

mscsi

entry is th e f irs t a l l zero entry in th e

file (see Modify the

mscsi File on page 6-8 for additional info rma tion) For SCO 3.2v4 .2 b ased UNIX, the boot entry looks li ke th is:

alad Sdsk 0 0 0 or blad Sdsk 0 0 0

For SCO OpenSer ver 5, the boot entry looks like thi s:

alad Sdsk 0 0 0 0 or blad Sdsk 0 0 0 0

Each field is separated by a tab (do not use the

This field applies to SCO OpenServer 5 only.

SCSI Device Type

Host Adapter Number

Target ID

Logical Unit Number Bus

– Host Adapter Prefix—Identifies the name of th e host

adapter driver. If you are booting from a 7800 Family ho st adapter, the Host Adapter Prefi x must be

alad or blad

– SCSI Device Type—Identifies the type of SCSI device. For

example, Sdsk indicates that the device is a hard disk; Srom indicates a CD-ROM drive; and Stp indicates a tape drive.

– Host Adapter Number—Identifies the SCSI host adapter

that the SCSI device is attached to. For example, the first 7800 Family host adapte r is 0, the second 7800 Family host adapter is 1.

– Target ID—Identifies the SCSI ID of the SCSI device. – Logical Unit Number —Identifies the Logical Unit Number

(LUN) of the SCSI device. This field is usually 0.

– Bus—Identifies the SCSI bus that the SCSI device is att ached

to. For most single channel devices su ch as the AHA2940/2940W, the bus number is 0.

If you need to edit the

file, use the vi editor. You m ust build a new kernel in order for any changes to take effect (see Rebuild the UNIX Kernel on page 6-9).

■

If you are booting fr om a 7800 Family host adapter and are using ISA/EISA-based host adapters as secondary devices, you must disab le the BIOS on all ISA/EISA-based host adapters.

If you are booting fro m ISA/EISA-based host adapters and are using a 7800 Family host adapter as a secondary device , see your ISA /EISA-based host adapter documentation to ensure the host adapter is at the lowest BIOS base address. ISA/EISAbased host adapters boot before the 7800 Family host adapters.

You may have to boot from the backup kernel created earlier. To boot from the backup kernel, follow these steps:

Reboot the system.

At the Booting UNIX System. .. prompt, type unix.orig and

press Enter. Your system should now boot from the backup kernel you

created prior to the driver update.
