Common Problems
SCSI Tape and Disk Tools report SCSI commands as failed in
the Test Activity Logs.
Some of the SCSI disk and tape tools log errors in their Test Activity logs indicating that
commands such as LOG SENSE and INQUIRY failed. This is usually because the drive
being tested is an older drive which did not implement these commands in the form they
are being used. If this is the case, the Cause/Action text in the log message will suggest
this as a possible cause of the problem.
No tools are available for a particular device.
Due to resource constraints, support tools for all device were not developed for this release.
Tools for these devices will probably be available in subsequent releases.
Some tools may not be available because they require a license. Currently the only tools
that require a license are expert tools. To see a list of the tools installed for a device and
the license level, if any, required to run the tool, use the "Device — >Current Device
Status…" command. The following is a display for a SCSI disk device:
Installed tools:
Diagnostic : None
Verifier : disk
Exerciser : disk
Informaton : scsi_disk
Expert Tool : scsi_disk (Licensed)
Firmware Update : scsi_disk
The "Device — >Select Class" command did not work.
This is usually because the "Device Type" and "Qualifier Type" you selected don't both
match a device in the system. For example, selecting a type of "Disk" and a qualifier of
"SCSI" will not select any devices because SCSI disks use qualifiers of "Hard," "Floppy,"
etc. Use the "Device — >Current Device Status" command to determine the valid type and
qualifier that apply to a specific device.
