CHAPTER 3 Component Configuration and Replacement (Add, Remove)
3.2 High availability configuration
Component
SB
CPU (*2)
DIMM (*2)
IOU (*3)
PCI_Box (*3) (*4)
*1: Hot remove of SB not possible.
*2: Physical replacement of CPU and DIMM as hardware is not possible. When replacing the CPU and the
DIMM, the SB is removed by the hot remove of SB. Or the partition is stopped.
*3: All PCI Express cards mounted in the partition must support PCI hot plug.
*4: DR function of PCI_Box is operated with DR function of IOU.
How to check the dr command package
Execute the following command, and check whether the dr command package has been installed.
# rpm –qa | grep FJSVdr-util
Example:
# rpm -qa | grep FJSVdr-util
FJSVdr-util-RHEL6-1.0.0-1.noarch
In case it has not been installed, see
Type of memory in DR
There are three types of memory of DR, shown below, depending on the conditions of use.
- Kernel memory
It is the memory internally used by the operating system. The kernel memory cannot be disconnected
from the system by SB hot-plug operation. It is secured from the memory of the Home SB at startup
- User memory
If is a memory in which the kernel memory is not loaded, the user memory can be hot-removed from the
system by the SB hot plug operation.
- Special memory
It is a hugetlbfs special memory. hugetlbfs cannot be disconnected from the system by SB hot plug
operation. Therefore, this memory is present only on the Home SB.
Notes / Limitations
- Two CPUs must be mounted on SBs in the partition where SB hot add is intended to be performed.
- All the SB firmware shall be of the same version number.
- Kernel memory is present only in the Home SB. Therefore, hot remove of Home SB is not supported.
- The Home SB cannot be changed to another SB while the partition is running. If you change the Home
SB, change it after powering off the partition.
- The DR function (SB hot add/ SB hot remove, IOU hot add/ IOU hot remove) is manually operated using
the DR operation of the MMB command of the command interface (CLI). There will be no automatic
processing in conjunction with proactive monitoring. DR operation is not possible in the maintenance
mode.
- When increasing the number of CPUs in the partition by SB hot add operation (hot add), additional CPU
licenses must be purchased for the software that is running in the relevant partition.
- The settings of the Reserved SB are deleted after the Reserved SB is incorporated into the partition by
hot add.
