Configuration Procedures
The following gives the installation procedure of AMDAS JDA in an EPC800 configuration.
This procedure does not pretend to replace the set of documentation which deals with
AMDAS, from which those procedure are extracted from.
The referenced publications are:
• Bull DPX/20 Escala AMDAS JBOD Storage System – Setup & Operator Guide
• Peripherals AMDAS Storage Subsystem Installation Guide, Product Manual
• Peripherals JDA/SDA7 Storage SubSystem, Product Manual
The procedures are specified with reference to the AMDAS disk configuration diagrams
generated by the ordering document.
Configurations for JDACF01 & JDACF02
1. Withdraw the three terminators on the SCSI II Fast/Wide differential board before being
implanted on the Escala node and if Y cables are used as links to the AMDAS cabinet.
2. Connect the Y cable.
3. Connect the terminator on the shorter branch of the Y cable.
4. Link the other branch of the Y cable and the first SCSI bus (J03 on AMDAS with a CBLG
157 cable).
5. Connect the other terminator on the connector J04 on the AMDAS.
6. Open the tray ” A ” and set the disk drives (1 to 6) in compliance with the implementation
order:
– 1 disk on slot 0
– 2 disks on slots 0 and 1
– 3 disks on slots 0, 1 and 2
– and so on.
The geographical slot gives the ID number of every disk. Refer to Bull DPX/20 Escala
AMDAS JBOD Storage Subsystem User’s Guide, Pages 2 – 5.
Note: Take into account the external bus ID number of the SCSI adapter on the node (7
is the default value). The bus ID cannot be given the following values: 1 to 5 nor
8 to 13 when all the disk slots of the AMDAS are used.
Refer to the corresponding diagrams in this document.
7. Connect the RS232 plugs on the power units of the AMDAS (J31) to two TTY lines on
the Escala node(s). This enables remote power–on/off of the AMDAS.
8. Set the configuration parameters of these two TTY ways under AIX as follows: 4800
bauds, 8 bit, 1 stop bit, none parity, ssmmgr as term type. Refer to Bull DPX/20 Escala
AMDAS JBOD Storage Subsystem User’s Guide, Pages 2 – 14.
9. Install the ” Maintenance Manager Software ” (Lpp DMMGR). To install the Maintenance
Manager, refer to Bull DPX/20 Escala AMDAS JBOD Storage Subsystem User’s Guide,
Chapter 4.
This link in particular allows to power ON/OFF the AMDAS and to invalidate one ore
more disk drives.
10.Check on the rear panel that the switch number 7 of the DIP Switch is set to OFF. Refer
to Bull DPX/20 Escala AMDAS JBOD Storage Subsystem User’s Guide, Pages 2 – 12.
11.Connect the power cords.
12.Power on. The switch is located under the fans on each power unit.
13.Under AIX, run the cfgmgr command that enables to discover the disks.
