Server320 - FDisk Shows Drives In Wrong Order

Applicable to: World-Wide

Symptom:
When running FDISK under OS/2 versions 2.11 or 3.0 (WARP), the fixed disk drives are shown in the wrong order.

Problem Isolation Aids:
The system is an IBM PC Server 520 (8641-EZ0, EZV). Multiple PCI Fast/Wide SCSI (Adaptec AHA-2940W) Adapters (FRU P/N 06H8574) are installed.

Fix:
Multiple PCI F/W SCSI Adapters (Adaptec AHA-2940W) require multiple basedev statements in the CONFIG.SYS file. The order of the basedev statements affects the order the drives appear in FDISK.

The multiple statements should be listed in the following order:
PCI slot 3, then 2, then 1.

PCI slot 3 is the shared PCI/EISA slot, slot 2 is the middle PCI slot, and slot 1 is the slot nearest the memory sockets).

For adapter in slot # basedev statement
--------------------- -----------------------------------
3 basedev=aic7870.add /a:1 /i /a:0 /i
2 basedev=aic7870.add /a:2 /i /a:0 /i
1 basedev=aic7870.add /a:2 /i /a:1 /i
