I'm having speed problems with the SCSI card we're using to do tape
backup. It seems to be functioning in 16 bit mode and the current
thinking is that perhaps it's using a legacy driver instead of the
correct one. The Adaptec site has a 'driver' for RHEL5 which I've
downloaded and tried to install but it seems to have a problem
installing on a CentOS-5 system.
Hit this same issue with a slightly different configuration, and although
not able to offer a solution, I can at least give some more boundary
conditions. As I see it now, it starts to look like a driver issue.
- I found the issue with a 39320 controller on CentOS5/i386,
talking to an Infortrend IFT-7250F enclosure. It should be doing U160
(Wide, 80 MHz synchonous), but it decays to 3.300 MB/s transfers.
The driver indeed even says the "Goal" is 3.300 MB/s ...
It is confirmed by the infortrend: it shows asynchonous/narrow as
transfer settings for the SCSI channels after loading the aic79xx driver.
- Exchanging the 39320 for a 29320, still on the same machine with
CentOS5/i386, does not change it: still 3.300 MB/s (as confirmed
by the infortrend itself)
- putting this same 29320, with the same IFT7250F and with the
same cabling, in another machine running CentOS3.7: presto, it
synchonizes again at 160 MB/s (Wide, 80 MHz)!
- similar Adaptec 29320 and 39320's in a CentOS4/i386 box, connected to
similar Infortrends: work correctly at 160 and 320 MB/s
- Booting into kernel 2.6.18-8.el5 or 2.6.18-8.1.8.el5 makes no difference
For CentOS5, the aic79xx driver is "Version: 3.0". For CentOS3 it's
using driver "1.3.10-RH1", and for the CentOS4 systems, it's "1.3.11".
What changed between 1.3.11 and 3.0?
At least you're not alone ...

DavidG.
PS: and indeed, the adaptec driver RPM does not install correctly, with
the same errors you reported below.
