Hello everyone,
we have system with 8 SCSI disks on Adaptec AIC7901 Ultra320 SCSI adapter.
The problem is they run too slow - 35MB/s benchmarked with hdparm.
It looks that the driver chooses slow rates to handle them:
User: 320.000MB/s transfers (160.000MHz DT|IU|RTI|QAS, 16bit)
Goal: 40.000MB/s transfers (40.000MHz)
Curr: 40.000MB/s transfers (40.000MHz)
This happens at boot time:
LQIRetry for LQICRCI_LQ to release ACK
(scsi0:A:10): 40.000MB/s transfers (20.000MHz DT, 16bit)
(scsi0:A:10): 40.000MB/s transfers (20.000MHz, 16bit)
(scsi0:A:10): 40.000MB/s transfers (40.000MHz)
(scsi0:A:11): 320.000MB/s transfers (160.000MHz DT|IU|RTI|QAS, 16bit
scsi0: Transmission error detected
(full error report at the end of mail)
Our hardware is:
motherboard Intel SE7210TP1-E (with onboard Adaptec 7901)
Chenbro case with SCSI backplanes
disks: 6x IBM 73GB 10k, 2x Maxtor Atlas 36GB 10k
Do you know how to fix this?
Have a nice day,
Michal Illich
