HI,
When one machine was started with one scsi device,the information
below was showed. Does anyone know how to fix this issue?
"scsi scan: INQUIRY result too short (5), using 36"
"Scsi 2:0:292:0: Direct-Access"

Well, it means what it says: the device wrongly returned only 5 bytes
for the INQUIRY command. Why it did this is a hardware issue.

The SCSI standard (SPC3) says
6.4.2 Standard INQUIRY data
The standard INQUIRY data (see table 81) shall contain at least
36 bytes.
