Hi, Has any one faced similar kind of problem? is there anything i should try out with aic7xxx parameters? Things are working fine but one disk is operating at 160MB/s instead of 320. We are running Rh7.2 with 2.4.20-13.7smp kernel. (With the default kernel there is no problem at all) Here's the dump ( /proc/scsi/scsi and /proc/scsi/aic7xxx1 ) cat /proc/scsi/aic7xxx/1 ------------------------- Adaptec AIC79xx driver version: 1.3.10 Adaptec AIC7902 Ultra320 SCSI adapter aic7902: Ultra320 Wide Channel B, SCSI Id=7, PCI-X 67-100Mhz, 512 SCBs Allocated SCBs: 360, SG List Length: 102 Serial EEPROM: 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x17c8 0x0974 0x0146 0x2807 0x0010 0xffff 0xffff 0xffff 0xffff 0xffff 0xffff 0xffff 0xffff 0xffff 0xffff 0x0410 0xb357 Target 0 Negotiation Settings User: 320.000MB/s transfers (160.000MHz RDSTRM|DT|IU|QAS, 16bit) Goal: 160.000MB/s transfers (80.000MHz DT|IU|QAS, 16bit) Curr: 160.000MB/s transfers (80.000MHz DT|IU|QAS, 16bit) Transmission Errors 0 Channel A Target 0 Lun 0 Settings Commands Queued 10572 Commands Active 0 Command Openings 128 Max Tagged Openings 253 Device Queue Frozen Count 0 Target 1 Negotiation Settings User: 320.000MB/s transfers (160.000MHz RDSTRM|DT|IU|QAS, 16bit) Goal: 320.000MB/s transfers (160.000MHz RDSTRM|DT|IU|QAS, 16bit) Curr: 320.000MB/s transfers (160.000MHz RDSTRM|DT|IU|QAS, 16bit) Transmission Errors 0 Channel A Target 1 Lun 0 Settings Commands Queued 10346 Commands Active 0 Command Openings 128 Max Tagged Openings 253 Device Queue Frozen Count 0 Target 2 Negotiation Settings User: 320.000MB/s transfers (160.000MHz RDSTRM|DT|IU|QAS, 16bit) Goal: 320.000MB/s transfers (160.000MHz RDSTRM|DT|IU|QAS, 16bit) Curr: 320.000MB/s transfers (160.000MHz RDSTRM|DT|IU|QAS, 16bit) cat /proc/scsi/scsi ------------------- Attached devices: Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: IC35L036UCDY10-0 Rev: S23C Type: Direct-Access ANSI SCSI revision: 03 Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: IBM Model: IC35L036UCDY10-0 Rev: S23C Type: Direct-Access ANSI SCSI revision: 03 Host: scsi1 Channel: 00 Id: 02 Lun: 00 Vendor: IBM Model: IC35L036UCDY10-0 Rev: S23C Type: Direct-Access ANSI SCSI revision: 03 Host: scsi1 Channel: 00 Id: 03 Lun: 00 Vendor: IBM Model: IC35L036UCDY10-0 Rev: S23C Type: Direct-Access ANSI SCSI revision: 03 cheers, vinoth --- Vinoth K <findvinoth@yahoo.com> wrote: > Hello all, > > Offlate I faced some problems with Redhat 7.2 with > upgraded kernel 2.4.20-13.7smp with U320 Adaptec > SCSI > controller (3920W - 7902).
