Before you update the OS SP, uninstall HDLM. After you have updated the OS
SP, re-install HDLM.
For details on HDLM installation and uninstallation, see
3.6 Installing HDLM
and
3.23.11 Uninstalling HDLM
.
If the number of I/O operations that have occurred in the system exceeds the
execution performance of the system (in an environment in which all of the
conditions below exist), the KAPL05008-E message and the call trace of a kernel
might be output.
•
Hitachi WMS exists in HDLM management-target devices.
•
In the utility for setting HDLM driver option (
dlmsetopt
), the number of
retries for allocating memory is set to 0 through 2,147,483,646.
In this case, the system might become unstable, and an error might occur in the I/
O that is being executed. In the
dlmsetopt
utility, set -1 or a value greater than
the current value for the number of retries for allocating memory, and then restart
the system. If a call trace is output even after the retry count is set to -1, consider
adding memory and stopping unnecessary processes.
When a device is dynamically configured by using the udev function, the
messages shown below might be output to the console or syslog. However,
HDLM operations are not affected.
Output example:
scsi_id[
a01
]: scsi_id: unable to access parent device of '/
block/sddlma01'
For
a01
in the above examples, any alphanumeric character can be output.
