SPARCclassic/SPARCclassic X/SPARCstation LX Service Manual • November 1993

4.3

Disk Drive Errors

TABLE 4-3

presents disk drive error conditions and corrective actions.

4.3.1

Verifying the Built-In SCSI Controller

To check whether the built-in SCSI controller is defective, test the drive response to
the

probe-scsi

command. To test additional SCSI host adapters added to the

system, use the

probe-scsi-all

command. Refer to Section C.1.5 “Probe-scsi,

Probe-scsi-all” on page C-7.

●

At the

ok

prompt, type

probe-scsi

.

See the following example.

TABLE 4-3

Troubleshooting Disk Drive Errors

Symptom

Corrective Action

Read, write, or parity error
reported by the operating system
or applications.

Replace the disk drive indicated by the failure
message. The operating system identifies the internal
disk drive 0 (SCSI target ID 3) as

sd0

and internal disk

drive 1 (SCSI target ID 1) as

sd1

.

Drive fails to boot or does not
respond to commands.

SCSI controller may be defective. See Section 4.3.1
“Verifying the Built-In SCSI Controller.” If SCSI
controller is OK, the SCSI ID jumpers or configuration
jumpers may be set incorrectly. Refer to Chapter 9
“Storage Devices.

Slow disk drive response.

If many SCSI devices are connected to the same SCSI
bus and if some of these devices, such as the 1.05-
Gbyte disk drive, are “fast SCSI” devices, you may
want to install an FSBE/S SCSI host adapter card to
the “fast SCSI” devices and put these “fast SCSI”
devices on a separate SCSI bus to speed up disk drive
response.
