If "INFO : 808 : Executed user programs at ADD_PRE timing" is not output, pre-process of the
collaboration program is delayed. Check which collaboration program takes a lot of time by seeing
/var/log/messages and 'collaboration program name.log' made in /opt/FJSVdr-util/var/log directory, if any.
Acquire the information of the collaboration program which takes a lot of time by below rpm command
and ask the Fujitsu engineer about the cause of its delay.
(Example) Checking the developer of the collaboration program "10-FJSVdr-util-kdump-restart"
$ rpm -qif /opt/FJSVdr-util/user_command/10-FJSVdr-util-
kdump-restart
...
Rebooting the partition is recommended because SB hot add process has been imperfect state.
2. Checking the time for activating added resources
Process of below messages in /var/log/messages is the process of activating added resources.
Dec 17 00:15:34 xxx dr-util[4457]: INFO : 802 : Add CPU30-59
(total 30)
Dec 17 00:15:34 xxx dr-util[4457]: INFO : 804 : Add
MEM98304-98559,114688-114943 (total 67108864 kiB)
...
Dec 17 00:15:47 xxx dr-util[4457]: INFO : 809 : Added SB3
If "INFO : 809 : Added SBX" is not output, process of activating added resources is delayed. Check that
the process of adding CPU or memory is performed by executing below command at several seconds.
- Checking the number of CPU
$ grep -c processor /proc/cpuinfo
30
- Checking the size of memory
$ cat /proc/meminfo |grep MemTotal
MemTotal:
In case that the number of CPU or the size of memory keeps increasing:
It is expected that cause of the delay is the load of the partition. The process of SB hot add can be
completed sooner by reducing the load of the partition.
In case that the number of CPU or the size of memory does not increase though they does not reach
expected quantity.
3. Checking post-process of collaboration program
Process of below messages in /var/log/messages is post-process of the collaboration program.
