possible read error.
Tape alert flags
Use this information to diagnose and resolve tape alert flags for the blade server.
Tape alert flags are numbered 1 through 64 and indicate a specific media-changer
error condition. Each tape alert is returned as an individual log parameter, and its
state is indicated in bit 0 of the 1-byte Parameter Value field of the log parameter.
When this bit is set to 1, the alert is active.
Each tape alert flag has one of the following severity levels:
Different tape drives support some or all of the following flags in the tape alert
log:
C - Critical
W - Warning
I - Information
Flag 2: Library Hardware B (W) This flag is set when an unrecoverable
mechanical error occurs.
Flag 4: Library Hardware D (C) This flag is set when the tape drive fails the
power-on self-test or a mechanical error occurs that requires a power cycle to
recover. This flag is internally cleared when the drive is powered-off.
Action
1. Insert a new CD or DVD into the optical drive
and wait for 15 seconds for the media to be
recognized; then, rerun the test. See "Diagnostic
tools overview" on page 97.
2. Make sure that the cable for the optical drive is
securely connected at both ends of the cable. See
your BladeCenter documentation for
information about the optical drive (media tray).
3. Make sure that the cable for the optical drive is
not damaged; then, replace the cable if damage
is present. See your BladeCenter documentation
for information about replacing the optical drive
(media tray).
4. Rerun the test. See "Diagnostic tools overview"
on page 97.
