Sounds like the SuSE 2.2.16 kernel doesn't know about the PCI IDs for the
3/Di on the PE2500.  That's not unusual, the servers came out about a year
*after* 2.2.16 was released. :-)

You'll need to add in the PCI IDs and rebuild your aacraid driver.

You really need the proper list of PCI IDs.  It's easiest to grab that from
the 2.4.9 patch at http://domsch.com/linux/ which has the list as up-to-date
as it can be today.  See the file aacid.c for the MiniPorts[] array, and
replace the version in your kernel with the one from 2.4.9.

FSA_MINIPORT MiniPorts[] = {
	{ 0x1028, 0x0001, 0x1028, 0x0001, "afa", RxInitDevice, "percraid",
"DELL    ", "PERCRAID        " }, /* PERC 2/Si */
	{ 0x1028, 0x0002, 0x1028, 0x0002, "afa", RxInitDevice, "percraid",
"DELL    ", "PERCRAID        " }, /* PERC 3/Di */
	{ 0x1028, 0x0003, 0x1028, 0x0003, "afa", RxInitDevice, "percraid",
"DELL    ", "PERCRAID        " }, /* PERC 3/Si */
	{ 0x1028, 0x0004, 0x1028, 0x00d0, "afa", RxInitDevice, "percraid",
"DELL    ", "PERCRAID        " }, /* PERC 3/Si */
	{ 0x1028, 0x0002, 0x1028, 0x00d1, "afa", RxInitDevice, "percraid",

	{ 0x1028, 0x0002, 0x1028, 0x00d9, "afa", RxInitDevice, "percraid",
"DELL    ", "PERCRAID        " }, /* PERC 3/Di */
	{ 0x1028, 0x000a, 0x1028, 0x0106, "afa", RxInitDevice, "percraid",
"DELL    ", "PERCRAID        " }, /* PERC 3/Di */

"DELL    ", "PERCRAID        " }, /* Dell PERC2 "Quad Channel" */
	{ 0x1011, 0x0046, 0x9005, 0x0365, "aac", SaInitDevice, "aacraid",
"ADAPTEC ", "Adaptec 5400S   " }, /* Adaptec 5400S */

};

Right.  They've already got one old version of aacraid, which is good!
Makes your life easier, you should just need to change the stuff as above.

No, you can just fix up what you've got.

Sure.  I'm sure SuSE's kernel has it as a module already.  See their .config
file.

I don't have such.  Maybe someone else will. :-)

Good luck!  If you can't figure this out, I suggest you call SuSE for
support.  I know they're capable of assisting in this.

Thanks,
