Sunfire 20K/25K Dynamic Reconfiguration

Here is the procedure for detaching one system board (SB13 from one domain (say Domain A) and adding the the same with another Domain (Domain F).

1. Make sure the board is available in Domain A

root@Domain-A # cfgadm -al|grep SB13
Ap_Id                          Type         Receptacle   Occupant     Condition
SB13                           V3CPU        connected    configured   ok
SB13::cpu0                     cpu          connected    configured   ok
SB13::cpu1                     cpu          connected    configured   ok
SB13::cpu2                     cpu          connected    configured   ok
SB13::cpu3                     cpu          connected    configured   ok
SB13::memory                   memory       connected    configured   ok

2. Disconnect the board from Domain A using below command.

root@Domain-A # cfgadm -c disconnect SB13

Below messages may be visible in system log while doing above activity.

root@Domain-A # tail -15 /var/adm/messages

3. Once the disconnect command is finished, check the SB status is showing as disconnected.

root@Domain-A # cfgadm -al|grep SB13
SB13 V3CPU disconnected unconfigured unknown

4. Now SB13 can be deleted from domain A and attached to domain F (from system controller)

Configuring Zpool with Solaris Zone

Set up details:
Server: globalzone
Zone name: testzone
1. Creating testpool named testpool with two disks in global zone

root@global # testpool create testpool c4t60050768018E8327B800000000000005d0s0

c4t60050768018E8327B800000000000008d0s0

2. Checking the status of created pool testpool

root@global # zpool status -v testpool

pool: testpool
state: ONLINE
scrub: none requested
config:

   NAME STATE READ WRITE CKSUM
   testpool ONLINE 0 0 0
   c4t60050768018E8327B800000000000005d0s0 ONLINE 0 0 0
   c4t60050768018E8327B800000000000008d0s0 ONLINE 0 0 0

errors: No known data errors

3. Adding the pool to zone

root@global # zoneadm -z testpool halt

root@global # zonecfg -z testpool

zonecfg:testzone> add dataset

zonecfg:testzone:dataset> set name="testpool"

zonecfg:testzone:dataset> end

zonecfg:testzone> commit

zonecfg:testzone> exit

root@global # zoneadm -z testzone boot

4. Creating first filesystem named mqm

root@testzone# zfs create testpool/mqm

5. Setting quota for each file sy stem

root@testzone# zfs set quota=110G testpool/apps
root@testzone# zfs set quota=1G testpool/oraapps
root@testzone# zfs set quota= 4G testpool/mqm

6. Changing mount point from non-global zone

bash-3.00# zfs set mountpoint=/apps testpool/apps
bash-3.00# zfs set mountpoint=/var/mqm testpool/mqm
bash-3.00# zfs set mountpoint=/oracle/orapp testpool/oraapps

7. Since we don’t need to pool to mounted, removing pool from mounting

bash-3.00# zfs set mountpoint=legacy testpool
