PC Server 315 - PC Server 315 hangs at Ctrl+A prompt during boot
Applicable to: World-Wide
SYMPTOM:
The system hangs displaying a Ctrl-A prompt to select the SCSISelect Utility when the system attempts to access the hard drive or floppy drive during boot.
PROBLEM ISOLATION AIDS:
All of the following must be true for this tip to apply:
- The system is a PC Server 315 type 8638 model.
- The system is configured with an Adaptec Ultra Wide SCSI adapter IBM Option p/n 76H5407 FRU p/n 76H5408/76H5394 or IBM Option p/n 76H3579 FRU p/n12J3094. The adapter is the primary boot controller.
- The Ultra Wide SCSI Adapter's "Reset SCSI Bus IC Initialization" setting in the SCSISelect utility is disabled. (Follow steps 2 and 3 in the FIX section to view this setting)
- The ASPI8DOS.SYS version used is below ver. 1.26 (36,756 k), and is called from the CONFIG.SYS file using the following syntax:
DEVICE=C:ASPI8DOS.SYS
Note: ASPI8DOS.SYS is typically located at the root of the C: drive.
----------------------- OR -----------------------
- The "Reset SCSI Bus IC Initialization" is DISABLED and the system is NOT calling a downlevel ASPI8DOS.SYS.
FIX:
Note: Proceed with step 1 through 7 if the system was configured to call a downlevel ASPI8DOS.SYS.
Note: Proceed with step 2 through 7 if the system was not configured to call a downlevel ASPI8DOS.SYS.
1- Replace the ASPI8DOS.SYS file located on drive C: with a ASPI8DOS.SYS ver 1.26 (or later) size 36,756 K, located on
the Diagnostics diskette as well as on the EZ-SCSI diskettes that ship with the server.
Note: the file on the EZ-SCSI diskette is compressed and therefore requires use of the included EXPAND utility.
2- Power on the system and press CTRL + A when prompted to start the SCSISelect utility, select "Configure Host Adapter
Settings", then press Enter.
3- Select "Advanced Configuration Options", press Enter.
4- Highlight the setting to the right of the "Reset SCSI Bus IC Initialization", press Enter, select "Enabled", press Enter.
5- Press Esc two times.
6- Select "Yes" to save changes when prompted, press Enter.
7- Press Esc, select "Yes" to exit the SCSISelect utility, press any key to restart system.
DETAIL:
If the "Reset SCSI Bus IC Initialization" is disabled, any subsequent cold boots will hang the system with the described Symptom.
The "Reset SCSI Bus IC Initialization" is disabled during boot if the backlevel ASPI8DOS.SYS is called from the CONFIG.SYS file.
