For disk errors, look for cxtxdx in the messages or the sd device equivalent..
Example, sd0 below, you can check against and compare the iostat -E and iostat -En command to find the correct disk.

All,
I am attempting to help tune a Sun for better performance (mainly for SAS 9.1), and have found indicators pointing to poor I/O utilization. I have run iostat -cx, and found one device in particular where the %w is in the 90's during processing. I have a feeling that this is where the SAS... (3 Replies)

tran_bus_reset
tran_bus_reset(9e) Driver Entry Points tran_bus_reset(9e)NAME
tran_bus_reset - reset a SCSI bus
SYNOPSIS
#include <sys/scsi/scsi.h> int prefix
tran_bus_reset(dev_info_t *hba_dip, int level);
INTERFACE LEVEL
Solaris DDI
PARAMETERS
hba_dip The dev_info_t pointer associated with the SCSI HBA.
level The level of reset required.
DESCRIPTION
The tran_bus_reset() vector in the scsi_hba_tran(9S) structure should be initialized during the HBA driver's attach(9E). It is an HBA
entry point to be called when a user initiates a bus reset through device control interfaces.
tran_bus_reset() must reset the SCSI bus without resetting targets.
level will be one of the following:
RESET_BUS Reset the SCSI bus only, not the targets.
Implementation is hardware specific. If it is not possible to reset the SCSI bus without changing the state and operating mode of the tar-
gets, the HBA driver should not initialize this vector or return failure.
RETURN VALUES
tran_bus_reset() should return:
1 on success.
0 on failure.
