PC Server 300 - PCI SCSI devices are not recognized
Applicable to: World-Wide
Symptom:
The system does not recognize the SCSI hard disk. (Eventually, the system will timeout attempting to identify it, however this could take a long time.)
Problem Isolation Aids:
All of the following must apply:
1. The system has a Pentium processor installed.
2. The system has a SCSI-2 FAST PCI-Bus adapter installed.
3. The correct PCI slot is enabled (0, 1 or 2) and IRQ 5, 11 or 15 is selected.
4. The SCSI fixed disk is properly cabled, jumpered and terminated.
Fix:
a. Remove the SRAM (Static Random Access Memory - CMOS) module IBM Internal Use Only from the socket at U50, located just above the IDE and diskette drive connectors (Refer to page 51 of the "User's Handbook" for the system board connector locations).
b. Wait for 5 minutes (to allow the module drain or discharge).
c. Reinstall the SRAM module in its socket, being careful not to bend the pins. Also be certain the MODULE IS PROPERLY ORIENTED, otherwise it could be DAMAGED. See diagram below.
d. Then, run the SETUP again.
