off: Do not output messages.
The default is off.
You do not need to reconfigure the hdisk or restart the host when you
change this parameter.
In the OS error log, HDLM messages are output when an error occurs on
a path or the path is recovered. You can distinguish between messages
for path errors and for path recovery by using labels in the OS error log.
¢
Label for a path error: HDLM_PATH_FAIL
¢
Label for path recovery: HDLM_PATH_RECOV
The label for path recovery is output if the Offline(E) or the Online(E)
paths become Online due to an online operation or automatic failback.
Take measures recommended by Recommended Actions in the OS error
log as necessary. In addition, the detailed data in the OS error log
contains maintenance information.
If a label for a path error is output, the detailed data contains the
following information:
• The first information item separated by spaces shows the
OSPathID (hexadecimal number) of a path with an error.
• The sixth information item separated by spaces shows the OS
error code (hexadecimal number) of the cause of the path error.
If a label for path recovery is output, the detailed data contains the
following information:
• The first information item separated by spaces shows the
OSPathID (hexadecimal number) of a path that has recovered
from an error.
If the message is output to the error log files (HDLM Manager log) at the
same time, check the content of that message also.
The following shows an example of an OS error log output by HDLM when
an error occurred on a path in the AIX 6.1 TL08 environment.In this
example, in the detailed data, the first information item separated by
spaces is 0001 indicating that OSPathID is 1, and the sixth information
item separated by spaces is 0005. Thus this OS error log indicates that
the OS error code 5 (EIO) has occurred.
