Hi,
I have recently been trying to set up eCS (or OS/2 Warp 4 for that matter) on an older Adaptec PCI AAA-131U2 card, which shows up as an Array1000 / 7880 chipset based SCSI card. It has hardware RAID, and I've been trying to get it to work set up with RAID-5. the specs on the card are at:
http://www.adaptec.com/en-US/support/_eol/aaa_raid/AAA-131U2/From what I can tell, this chipset should work with the AIC7870.add driver. I've found references on Adaptec's website saying that this card is fully supported on OS/2 using drivers that came on the OS/2 install CD.
My difficulty is that for some reason I can't get OS/2 to recognize the full size of an array. When I've tried with Warp 4, if the array is already configured and formatted (using the Adaptec utility and formatted with a windows 2000 or xp disc), if I try and reformat it to HPFS, then format gives me an error:
SYS0529: Not enough memory is available to run FORMAT
There is enough memory on this system, right now I've got it set up with 128 MB.
If I already have a partition set up and formatted (setting it up and formatting it with Windows 2000 / XP after having built the array using Adaptec's utility) OS/2's fdisk (the updated one that was fixed for the large disk partition sizes) can *see* that there is an NTFS partition of 34GB - the full size of the array, but format will not let me format (same error as above). If I try and rebuild the partition with OS/2's fdisk, once I delete the partition that is there, the most it will let me create is an 8 GB partition. If I create an 8 GB partition, I can then format it, but this is not what I want.
For further testing, I decided to just install a single 18GB SCSI drive on the card, not setting up any type of RAID array. I still ran into the situation, the most that OS/2 will recognize is 8 GB.
I tried to get eCS to work, however eCS 1.2 MR was unable to recognize any drives. I suspect there may be something that is not working properly with the AIC7870.ADD driver in eCS 1.2
For test purposes, I've tried both RAID-5 and RAID-1 arrays with a selection of 18.2 GB drives. I know that everything works as it should - I've been able to successfully install Windows 2000 and XP on it, and it recognizes the full size of the array and everything seems to work. I'm just having issues finding the correct driver for OS/2.
Does anyone have any suggestions?
