Disk Subsystems Cabling Requirements
Configurations for JDACF03 & JDACF04
1. Follow the steps 1 to 3 of procedure above for each node to connect to an AMDAS.
2. Link the other branch of the Y cable of a node and the first SCSI bus (J03) on AMDAS
with a CBLG 157 cable.
Link the other branch of the Y cable of the other node and the first SCSI bus (J07) on
AMDAS with a CBLG 157 cable.
3. Connect the two terminators to the connectors J04 and J08 on the AMDAS.
4. Set the disk drives (2 to 12) in the trays A and D and (13 to 24 disks) in the trays B and E
of the AMDAS in compliance with the implementation order. Refer to Bull DPX/20 Escala
AMDAS JBOD Storage Subsystem User Guide , Pages 2 – 5.
Note: The ID number of the SCSI adapters on the nodes are set to 7 per default. These
IDs cannot be given the following values: 1 to 5 nor 8 to 13 when all the disk
slots of the AMDAS are used.
5. For the use of the ” Maintenance Manager Software ” (Lpp DMMGR),
connect the RS232 serial lines as shown in the steps 7 to 9 of the procedure above,
knowing that to power on/off the AMDAS, it is necessary to act on every power unit of
the AMDAS.
Note:
The two serial lines can be distributed on the two nodes. Using the ” Maintenance
Manager ” to power off or power on the AMDAS does not prevent from using the
physical switch on/off on each power unit
6. Follow the steps 10 to 13 of the procedure above in order to complete the installation of
the AMDAS.
Configurations for JDACF05 & JDACF06
1. Follow the steps 1 to 3 of the procedure above: to withdraw the terminators on the
adapters; to set; to connect the Y cables and the terminators.
2. Connect the other branch of the Y cable of one of the adapters to the first SCSI bus on
J03 of the AMDAS with a cable CBLG 157.
3. Connect the other branch of the Y cable on the second adapter to the second SCSI bus
on J07 of the AMDAS with a cable CBLG 157.
4. Connect the 2 terminators on the connectors J04 and J08 of the AMDAS.
5. Put the disk drives in the trays A and D (2 to 12 disks) and the trays B and E (13 to 24
disks) of the AMDAS in compliance with the implementation rules specified AMDAS
JBOD Storage Subsystem, pages 2 to 5.
Note: The ID number of the SCSI II Fast/Wide adapters in the Powercluster nodes are
given a value 7 per default. They cannot be given a value 1 to 5 nor 8 to 13, when all
the disk slots of the AMDAS are used.
6. Follow the steps 7 to 13 of the procedure above.
