  9. 10.3 Removal of Expansion Rack 2, and Decrease of the Number of SPARC M10-4S Units to Four or Less

10.3 Removal of Expansion Rack 2, and Decrease of the Number of SPARC M10-4S Units to Four or Less


10.3 Removal of Expansion Rack 2, and Decrease of the Number of SPARC M10-4S Units to Four or Less
This section describes the procedure to remove expansion rack 2 and reduce the SPARC M10-4S units to four or less in expansion rack 1 (connection via a crossbar box). This procedure corresponds to pattern C in Figure 8-3. You need to stop the system during this work.

For details on the XSCF commands executed in each step, see the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 XSCF Reference Manual.
  1. Log in to the master XSCF.
    Execute the showbbstatus command to confirm that the XSCF to which you have logged in is the master XSCF.
    If it is a standby XSCF, retry to log in to the master XSCF.
XSCF> showbbstatus
BB#00 (Master)
  1. Execute the showhardconf command, and confirm the chassis serial number of the system board (PSB) targeted for release.
    For details, see "A.2.1 Checking the component status."
Note - If the serial number of the target chassis is being used as the system serial number, the initbb command cannot release the chassis. In this case, execute the switchscf command to switch the master XSCF.
  1. Execute the poweroff command to stop all the physical partitions.
XSCF> poweroff -y -a
PPAR-IDs to power off:00,01,02,03,04,05,06,07,08,09,10,11

  1. Execute the deleteboard command from the master XSCF to release a system board (PSB) from the physical partition configuration.
    The following example releases system boards 04-0, 05-0, 06-0, 07-0, 08-0, 09-0, 10-0, and 11-0 from the physical partition.
XSCF> deleteboard -c unassign 04-0 05-0 06-0 07-0 08-0 09-0 10-0 11-0
PSB#04-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#05-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#06-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#07-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#08-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#09-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#10-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#11-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
  1. Execute the showresult command, and confirm the end status of the previously executed deleteboard command.
    In the following example, 0 is returned as the end status, so the execution of the deleteboard command has completed correctly.
XSCF> showresult
0
  1. Execute the showboards command to check the system board (PSB) status.
    In the following example, system boards 04-0, 05-0, 06-0, 07-0, 08-0, 09-0, 10-0, and 11-0 are in the system board pool.
XSCF> showboards -a

  1. Execute the initbb command from the master XSCF to release the SPARC M10-4S to be removed from the system and initialize it.
    In bb_id, specify the ID (BB-ID) identifying the chassis.
XSCF> initbb -b bb_id
  1. The following example releases BB#11 from the system and initializes it.
XSCF> initbb -b 11
You are about to initialize BB/XB-Box.
NOTE the following.
1. BB/XB-Box is excluded from the system and halted.

2. PPAR-ID of the same value as BB-ID becomes invalid.

Continue? [y|n] :y
Note - After the execution of the initbb command, the target chassis is released from the system and enters the stopped state. Do not disconnect the power cords or various cables until the XSCF STANDBY LED on the panel and the rear READY LED of the target chassis are off.
  1. Execute step 7 on each chassis of the SPARC M10-4S to be removed.
  1. Confirm that the LED of the SPARC M10-4S to be removed is off, and then disconnect all the power codes of the chassis from the input power.
  1. Disconnect the cables that pass between the racks.
    Crossbar cables (optical) that pass between the racks are laid with spiral tubes.
    Disconnect cables from expansion rack 1, and lay them together in expansion rack 2.
  1. Disconnect expansion rack 1 from expansion rack 2.
    Disconnect the racks in the reverse order at the rack connection. For the procedure for the rack connection, see "3.3.3 Connecting racks."
  1. Remove the XSCF-BB control cables from the target SPARC M10-4S on expansion rack 1.
  2. Remove the crossbar cables (optical) from the target SPARC M10-4S on expansion rack 1.
Note - Do not hold the cable part when pulling out the crossbar cable. Pulling the cable part without the connector lock completely released may cause damage.
  1. Remove the target SPARC M10-4S from expansion rack 1.
    Remove the SPARC M10-4S from the rack by reversing the mounting procedure. For the procedure for mounting in the rack, see "3.4.1 Mounting the SPARC M10-4S in a rack."
The removed SPARC M10-4S enters the factory default status because the initbb command is executed. If you want to use it as another system, see "1.1 Workflow for the SPARC M10-4S" to perform installation.
