another location. Here is an example of an error log record for a device that is attached to a Linux
operating system:

Figure 29: Linux Error Log record example
The following information describes the various error log entries that are depicted in Figure 29 on page
70.
First line
Provides the tape device special file name, the device serial, and the time stamp of when the error
message was recorded.
SCSI Path
Identifies the SCSI path for the logical unit. This path matches the order of the SCSI/Channel/ID/LUN
information in the
/proc/scsi/scsi file
.
CDB Command
The command data block of the SCSI command.
Status Code
The returned result from the Linux SCSI middle layer device driver scsi_mod.o. The 4 bytes represent
driver_byte, host_byte, msg_byte, and status_byte.
Sense Data
The full SCSI data that is returned from the target.
Description
Human-readable text string that is obtained by parsing the sense key field of the sense data.
Obtaining drive error information from Solaris system
The Solaris system does not provide error logs for analysis. Therefore, you must use the device diagnostic
tests and Device Error Log for problem determination. See “CE Logs menu (CE Offline Mode)” on page
133. When you locate a FID, go to “Maintenance starting point” on page 1.
See “TAPEUTIL in Sun (Solaris) system environment” on page 263 for information about the host
attachment software service tool tapeutil for Solaris systems.
Refer to the IBM Tape Device Drivers Installation and User's Guide for information about Solaris service
and diagnostic aids.
