Re: Disk upgrade and IOP compatibility

I am not an expert at this stuff.  I looked in the Feb 1999
Systems Handbook GA19-5486-18 in the 170 section.
You probably have a #2809 PCI Base MFIOP with a #9728 Base PCI
Disk Unit Controller.  The description of the #9728 on pages
211 and 212 say that it can handle up to 5 disks with no cache
and no RAID.  It goes on to say that it will control #6824
(18 gigabyte) and #6813 (8 gigabyte) drives.  It does not list
any other 18 or 8 gigabyte drives, although it does mention
smaller drives...

If you have RAID, the disk controller is either #2726, #2740,
or #2741.  I couldn't find anything that listed a #675A IOP.

Let us know what the outcome is.

Good Luck,
