Purpose
Changes the state of a partition. This command is operable only in the Integrated Virtualization Manager environment.
chsysstate -r lpar -o on { -n Name | --id PartitionID } [ -k KeylockPosition ] [ -b BootMode ] [ -m ManagedSystem ]
-f partition-profile-name
partition-profile-name都可以在hmc里面查看。
ManagedSystem_Name是物理服务器。
下面是个范例：
chsysstate -r lpar -o on -m ManagedSystem_Name -n lpar_host_name -f lpar_host_name -b sms
启动lpar，状态是power on，管理系统是ManagedSystem_Name,partition name是lpar_host_name， -f是profile名字，hmc里面可以查看到，启动到sms状态。
然后重新安装系统，用备份的文件。
-r ResourceType The type of resources to change: lpar Logical partition resources
-m ManagedSystem The name of the managed system. This attribute is optional because there is only one system to manage. The name may either be the user-defined name for the managed system, or be in the form tttt-mmm*ssssssss, where tttt is the machine type, mmm is the model, and ssssssss is the serial number of the managed system.
-o Operation The type of operation to perform:
chkey: Changes the keylock position
consoleservice: Disables a remote service session for the IBM? i partition (operator panel function 65) followed by the activation of the dedicated service tools for the IBM i partition (operator panel function 21).
dston: Activates dedicated service tools for the IBM i partition (operator panel function 21).
dumprestart: Restarts after initiating a dump
iopdump: Allows use of the IOP control storage dump (operator panel function 70). This operation is valid for IBM i partitions only.
iopreset: Resets or reloads the failed IOP (operator panel function 67). This operation is valid for IBM i partitions only.
on: Power on
osshutdown: Shuts down using the client partition's shutdown command. This is the safest shutdown option, so should be used if available (RMC state must be active).
remotedston: Enables a remote service session for the IBM i partition (operator panel function 66).
retrydump: Retries the dump on the IBM i partition and restarts the partition when the dump is complete (operator panel function 34).
shutdown: Shuts down
remotedstoff: Disables a remote service session for the IBM i partition (operator panel function 65).
-b BootMode Override the current power on mode setting. Valid values are:
norm: normal
dd: diagnostic with default boot list
ds: diagnostic with stored boot list
of: Open Firmware OK prompt
sms: System Management Services
查看当前的状态
lssyscfg -m ManagedSystem_Name -r lpar -F name:state
hmc_name:~> lssyscfg -m ManagedSystem_Name -r lpar -F name:state
lpar_host_name:Running
Description
The lssyscfg command lists attributes of partitions, partition profiles, or the managed system.
先登录到HMC状态，启动lpar，配制好网络启动，然后恢复。恢复的过程中hdisk0的名字会改变，但是pvid不会变，另外在sms启动的状态可以查看hdisk0的大小，pvid等信息来确认要恢复的rootvg
