Appendix E. TapeAlert Flags TapeAlert is a standard that defines various status conditions and problems experienced by such devices as tape drives, tape autoloaders, and tape libraries. Developed by Hewlett-Packard, the standard enables a host to read TapeAlert flags from a tape drive via the SCSI bus. The host reads the flags from Log Sense Page 0x2E.

Set when you load a cleaning cartridge into the drive. No action required. Set when you load an unsupported cartridge type into the drive or when the cartridge format has been corrupted. Use a supported tape cartridge. © Copyright IBM Corp. 2000 69

Appendix E. TapeAlert Flags
TapeAlert is a standard that defines various status conditions and problems
experienced by such devices as tape drives, tape autoloaders, and tape libraries.
Developed by Hewlett-Packard, the standard enables a host to read TapeAlert flags
from a tape drive via the SCSI bus. The host reads the flags from Log Sense Page
0x2E. This appendix lists the TapeAlert flags that are supported by the 3580 Tape
Drive.
TapeAlert Flags Supported by the 3580 Tape Drive
Flag
Number
Flag
Description
Action Required
3
Hard error
Set for any unrecoverable read,
write, or positioning error. (This flag
is set in conjunction with flags 4, 5,
or 6.)
See the Action Required column for
Flag Number 4, 5, or 6 in this table.
4
Media
Set for any unrecoverable read,
write, or positioning error that is due
to a faulty tape cartridge.
Replace the tape cartridge.
5
Read failure
Set for any unrecoverable read error
where isolation is uncertain and
failure could be due to a faulty tape
cartridge or to faulty drive hardware.
If Flag 4 is also set, the cartridge is
defective. Replace the tape cartridge.
If Flag 4 is not set, see “Chapter 5.
Troubleshooting” on page 35.
6
Write failure
Set for any unrecoverable write or
positioning error where isolation is
uncertain and failure could be due to
a faulty tape cartridge or to faulty
drive hardware.
If Flag 4 is also set, the cartridge is
defective. Replace the tape cartridge.
If Flag 4 is not set, see “Chapter 5.
Troubleshooting” on page 35.
9
Write protect
Set when the tape drive detects that
the tape cartridge is write protected.
Make sure that the cartridge’s
write-protect switch is set so that the
tape drive can write data to the tape
(see “Setting the Write-Protect
Switch” on page 26).
10
No removal
Set when the tape drive receives an
unload command after the host
prevented the tape cartridge from
being removed.
Refer to the documentation for your
host operating system.
11
Cleaning media
Set when you load a cleaning
cartridge into the drive.
No action required.
12
Unsupported format
Set when you load an unsupported
cartridge type into the drive or when
the cartridge format has been
corrupted.
Use a supported tape cartridge.
