Selecting A System Volume; System Control And Operation Environment - Fujitsu PRIMEPOWER 1000 User Manual

CHAPTER 6 System Configuration
For details on the SMC, see the
user's manual supplied with the SMC. (The manual is not applicable to the PRIMESTATION as
SMC, for this refer to the system administrator's guide "PRIMESTATION as LAN Console or
SMC".)
(4) File unit for a system volume
l The disk mounted in the Expansion File Unit is to be used as a system volume.
l This unit must be prepared in accordance with the configuration of the main unit.
6.1.2

Selecting a System Volume

The Expansion File Unit (UltraSCSI 2 ports) can be used as a system volume.
Up to 10 disks can be internally mounted on this file unit. This Expansion File Unit contains a
power supply and a fan which are hot swappable, providing system redundancy.
6.1.3

System Control and Operation Environment

SMC is a dedicated control unit for the main unit. As such, the SMC is connected to the main
unit using the interfaces described below and controlled by System Console Software developed
specifically for the SMC.
(1) HUB for System Control LAN (10Base-T), and LAN cables up to 30 m (98 ft)
l Used to establish a private LAN between the System Control Facility. In the standard
configuration, one HUB must be implemented.
l When the System Control Facilities are configured redundantly (e.g. System Control
Facility board option installed), two HUBs must be installed for the respective System
Control LANs.
l Four or more HUB ports must be installed to support this configuration. The number of
required ports depends on factors such as the system size (e.g. the number of partitions) and
whether or not the cluster configuration is enabled.
(2) HUB for User LAN (100Base-TX), and LAN cables
This HUB must be installed between the on-board LAN port on the System Board of the
partition and the User LAN port of the SMC. Be sure to prepare HUB and LAN cables as
required for the User LANs. A User LAN must be connected to the LAN port of the System
Board bearing the lowest number among the System Boards that construct the partition.
(3) Time synchronize function
l Time information on the main unit is synchronized to the time information in the SMC using
the NTP. If the SMC is not active, the OS uses the time information in the main unit as the
default value on boot-up process.
