Validating the simplified remote restart operation of a logical partition

You can validate the simplified remote restart operation of an AIX®, Linux®, or IBM® i logical partition by using the Hardware Management Console (HMC) command-line interface.

Before you begin

When the source and destination servers are managed by different Hardware Management Consoles, you must ensure that the HMC at the source server and the destination server is at version 8.5.0 or later.

Note: When the HMC is at Version 9.2.950, or later, and the firmware is at a level FW950, or later, for the remote restart operation to be successful on the logical partition that supports platform keystore capability, the user-defined system key that is configured on both the source and the destination system must match.

Procedure

To validate the simplified remote restart operation of a logical partition, type the following command from the HMC command line:
```
rrstartlpar -m <source managed system> -t <target managed system> -p <lpar name> |
--id <lpar id> -o validate
```
To validate the simplified remote restart operation of a logical partition when the source server and the destination server are managed by a different HMC, type the following command:
```
rrstartlpar -m <source managed system> -t <target managed system> -p <lpar name> | 
--id <lpar id>  --ip <IP address> [-u <user ID>] -o validate
```
Where
- IP address is the IP address or the host name of the HMC that manages the destination server.
- user ID is the user ID that is used on the HMC that manages the destination server.
If the HMC at the destination server is not at version 8.5.0 or later, the validation operation fails and error messages are displayed for your appropriate action.
To specify the destination shared processor pool, type the following command from the HMC command line:
```
rrstartlpar -m <source managed system> -t <target managed system> -p <lpar name>
| --id <lpar id> --ip <IP address> [-u <user ID>] - i|f 
“shared_proc_pool_name=<spp name>|shared_proc_pool_id=<spp id>” -o validate
```
Where
- shared_proc_pool_name is the name of the shared processor pool on the destination server.
- shared_proc_pool_id is the ID of the shared processor pool.
Note: The shared_proc_pool_id and shared_proc_pool_name attributes are mutually exclusive.

To specify the destination virtual Fibre Channel mapping, type the following command from the HMC command line:

rrstartlpar -m <source managed system> -t <target managed system> -p <lpar name> 
| --id <lpar id> --ip  <IP address> [-u <user ID>] - i|f  “virtual_fc_mappings
=slot_num/vios_lpar_name/vios_lpar_id/[vios_slot_num]/[vios_fc_port_name]”  -o validate

Where

slot num is virtual Fibre Channel slot number.
vios_slot_num is virtual Fibre Channel slot number of the VIOS.

To validate the simplified remote restart operation of a logical partition with a different number of dedicated processors or virtual processors on the destination server than what the partition was assigned on the source server, or with a different number of shared processing units on the destination server than what the logical partition was assigned on the source server, type the following command from the HMC command line:
```
rrstartlpar -o validate -m <managed system> -t <target system> [-p <partition name>
| --id <partition ID>] -i “desired_procs = <desired procs absolute value>|min, 
desired_proc_units = <desired proc units absolute value>|min”
```
The value for the desired_procs attribute indicates the number of processors with which logical partition can be restarted. The following are the possible values for this attribute:
- desired procs absolute value - Must be greater than or equal to the current minimum dedicated processors or virtual processors, and less than or equal to current maximum dedicated processors or virtual processors.
- desired proc units absolute value - Must be greater than or equal to the current minimum processing units, and less than or equal to current maximum processing units.
- min - The value of the current minimum processing units, or the current minimum dedicated processors or virtual processors. In the case of dedicated processors, the logical partition is started with the minimum number of dedicated processors or virtual processors the logical partition was assigned on the source server. In the case of shared processors, the logical partition is started with the minimum number of shared processing units the partition was assigned on the source server.
To validate the simplified remote restart operation of a logical partition when you want to start the logical partition with a different amount of memory on the destination server than what the logical partition was assigned on the source server, type the following command from the HMC command line:
```
rrstartlpar -o validate -m <managed system> -t <target system> [-p <partition name>
 | --id <partition ID>]  -i “desired_mem = <desired absolute memory>|min”
```
The value for the desired_mem attribute indicates the amount of memory with which the logical partition can be restarted. The following are the possible values for this attribute:
- desired_absolute_memory - Must be greater than or equal to the current minimum memory, and less than or equal to current maximum memory.
- min - The value of the current minimum memory. The logical partition is started with the minimum amount of memory the logical partition was assigned on the source server.
To validate the simplified remote restart operation of a logical partition when you want to start the logical partition with a different virtual switch on the destination server than what the logical partition was assigned on the source server, type the following command from the HMC command line:
```
rrstartlpar -o validate -m <managed system> -t <target system> [-p <partition name> 
| --id <partition ID>] -i “vswitch_mappings = <vlanId_1>/<source_vswitchName_1>/
<target_vswitchName_1>, …, <vlanId_n>/<source_vswitchName_n>/<target_vswitchName_n>”]”
```
