HP NetServer 5971-0821 manual My computer does not recognize my Scsi devices

Troubleshooting

My computer does not recognize my SCSI devices.

At boot time, check to see if the BIOS messages for your primary Ultra3 host bus adapter lists all installed SCSI devices. If some or all devices do not appear, check your host bus adapter User’s Guide for additional troubleshooting information, and check the following:

•Are all SCSI devices powered on?

•Are all SCSI bus cables and power cables properly connected?

•Do the host bus 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 peripherals may lock or reset the SCSI bus. To solve this problem, turn off synchronous negotiation for this device ID through the SCSISelect utility for the host adapter.

My computer does not recognize my host adapter.

At boot time, check to see if the BIOS message for your primary Ultra3 SCSI host bus adapter appears. If the messages do not appear, the host bus adapter may not be properly configured; check the following:

•The HP Ultra3 SCSI host bus adapter supports level-triggered interrupts and can share the same interrupt with another HP Ultra3 SCSI host bus adapter or PCI hardware that also supports level-triggered interrupts. Check your host bus adapter User’s Guide and the documentation supplied with your computer for information about configuring IRQs and other parameters in the system CMOS setup.

•The boot host bus 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 HP Ultra3 SCSI host bus adapter(s):

a Run the SCSISelect utility (by pressing a key combination displayed on-screen at boot time)
