detach and attach CPU to Sun Fire 12K

detach von zwei CPU,s , jede CPU einzeln eingegeben, ohne/mit Reboot im online Betrieb

Zur Info: Domain CPU deaktivieren:

- Wenn man auf Domain psradm –f [cpuID] durchführt,  bleibt die Memory  bestehen (psradm besteht nur für eine Sitzung).
   Mann kann auch cfgadm -c configure SB2::cpu3 verwenden

- Wenn man auf SC über blacklist die cpu deaktiviert, dann ist das Memory das sich auf den Board befindet auch weg(Achtung).

Detach of CPU:

1.) Output:

SB7::cpu3                      cpu          connected    configured   ok

2.) Überprüfen wie viel einzelne Cpu’s vorhanden sind.
sms-svc:> showcomponent -d E

sms-svc:> showcomponent -d E SB7/P0

Component PROC at SB7/P0 is NOT disabled in the specified blacklist.

sms-svc:> showcomponent -d E SB7/P1

 Component PROC at SB7/P1 is NOT disabled in the specified blacklist.

sms-svc:> showcomponent -d E SB7/P2

 Component PROC at SB7/P2 is NOT disabled in the specified blacklist.

sms-svc:> showcomponent -d E SB7/P3

 Component PROC at SB7/P3 is NOT disabled in the specified blacklist.

sms-svc:> showcomponent -d E SB7/P4        ## CPU 4 ist nicht vorhanden

ERROR: Invalid component: SB7/P4

3.) Disable von zwei einzelnen Cpu’s über SC-Board
sms-svc:> disablecomponent -d E SB7/P2
sms-svc:> disablecomponent -d E SB7/P3

4.) Blacklist Datei wurde gefüllt.
Zur Info: Wenn man die cpu blacklistet wird auch die Memory die sich auf den Board befindet auch disabled !!!

sms-svc:> more /etc/opt/SUNWSMS/SMS1.5/config/E/blacklist

5.) Auf der Domain laufen noch die Cpu’s

SB7::cpu1                      cpu          connected    configured   ok

SB7::cpu3                      cpu          connected    configured   ok

6.) Im Laufenden Betrieb die Cpu’s herraus Konfiegurieren
root# cfgadm -c unconfigure SB7::cpu3
root# cfgadm -c unconfigure SB7::cpu2

7.) Nochmals Prüfen
root@RFX141 # psrinfo

224     on-line   since 05/11/06 15:25:19
225     on-line   since 05/11/06 15:25:2

SB7::cpu2                      cpu          connected    unconfigured ok
SB7::cpu3                      cpu          connected    unconfigured o

Zur Info:  Man braucht kein Reboot (init 6), aber zur Kontrolle habe ich einen Durchgeführt, ob die Blacklist File angezogen wird.

Nach reboot:
root# psrinfo

224     on-line   since 05/15/06 16:09:19
225     on-line   since 05/15/06 16:09:20

Attach of CPU:

1.) Nochmals Prüfen
root# psrinfo -p

3

root# cfgadm -al

Ap_Id                          Type         Receptacle   Occupant     Condition

SB2::cpu3                      cpu          connected    unconfigured ok
SB2::memory                    memory       connected    configured   ok

2.) Cpu einbinden auf Domain 
root# cfgadm -c configure SB2::cpu3
root# cfgadm -al

Ap_Id                          Type         Receptacle   Occupant     Condition
SB2                            V3CPU        connected    configured   ok
SB2::cpu0                      cpu          connected    configured   ok
SB2::cpu1                      cpu          connected    configured   ok
SB2::cpu2                      cpu          connected    configured   ok
SB2::cpu3                      cpu          connected    configured   ok
SB2::memory                    memory       connected    configured   ok

3.) Auf SC Board,  CPU aus Blacklist herausnehmen.
