5.5 Powering Off the Physical Partition Requiring Maintenance


5.5 Powering Off the Physical Partition Requiring Maintenance
This section describes the procedure for powering off the physical partition requiring maintenance. This applies if the system has a building block configuration and is operating in multiple physical partitions.
Note - Before stopping physical partitions, inform the users of those physical partitions that the physical partitions will be stopped.
Note - When a physical partition is stopped by the operation of the XSCF command or the operation panel, all the logical domains on the physical partition are stopped. Stop applications as required.
  1. Log in to the XSCF shell.
  2. If the chassis requiring maintenance is operating as the master chassis, execute the switchscf command to switch the master XSCF to the standby XSCF.
    Enter "y" in response to the confirmation message.
    If the chassis requiring maintenance is the slave XSCF, go to step 4.
XSCF> switchscf -t Master
The XSCF unit switch between the Master and Standby states.
Continue? [y|n] :y
  1. Log in to the master XSCF again.
  2. Execute the showpparstatus command to check the operating condition of the physical partition.
    In the following example, [PPAR STATUS] displays "Running" for PPAR-ID 00, indicating that the physical partition is operating.
XSCF> showpparstatus -p 0
PPAR-ID        PPAR Status
00             Running 
  1. Execute the showdomainstatus command to check the operating condition of the logical domains.
    In the following example, [Status] of the logical domain displays "Solaris running", which indicates that Oracle Solaris is operating.
XSCF>  showdomainstatus -p 0
Logical Domain Name   Status
primary               Solaris running
4S-159-D0-G0          Solaris running
4S-159-D0-G1          Solaris running
4S-159-D0-G2          Solaris running
  1. Execute the showboards command to check the status of the chassis requiring maintenance.
    The BB-ID of the chassis requiring maintenance is indicated by the system board (PSB) number.
    In the following example, we can see that [PPAR-ID] of PSB 00-0 is "00."
XSCF> showboards -a
PSB  PPAR-ID(LSB) Assignment  Pwr  Conn Conf Test    Fault     
---- ------------ ----------- ---- ---- ---- ------- --------  

00-0 00(00)       Assigned    y    y    y    Passed  Normal
01-0 00(01)       Assigned    y    y    y    Passed  Normal
02-0 00(02)       Assigned    y    y    y    Passed  Normal
03-0 00(03)       Assigned    y    y    y    Passed  Normal
  1. Execute the poweroff command to stop all the logical domains on the physical partition requiring maintenance.
    Enter "y" in response to the confirmation message.
XSCF> poweroff -p 0
PPAR-IDs to power off:00
Continue? [y|n] :y
00 : Powering off

*Note*
 This command only issues the instruction to power-off.
 The result of the instruction can be checked by the "showpparprogress".
  1. Execute the showpparstatus command to confirm that the power to the physical partition has been turned off.
    In the following example, [PPAR Status] of PPAR-ID 00 displays "Powered Off", which indicates that the power to the physical partition has been turned off.
XSCF> showpparstatus -p 0
PPAR-ID        PPAR Status
00             Powered Off
